Tension-Compression Fatigue of Hi-Nicalon/SiC Ceramic Matrix Composite at 1200 C in Air and Steam
The tension-compression fatigue of a Hi-Nicalon /Silicon Carbide ceramic matrix composite (CMC) was studied at 1200?簞C in laboratory air and in steam environment. The CMC investigated in this effort consisted of an oxidation inhibited HyprSiC matrix reinforced with laminated woven Hi-Nicalon fibers. Fiber preforms had pyrolytic carbon fiber coating with boron carbide overlay applied were then densified with the HyprSiC oxidation inhibited matrix through chemical vapor infiltration (CVI). The tensile stressstrain behavior was evaluated and the tensile properties measured at 1200?簞C. Tension-compression fatigue tests were conducted at a frequency of 1.0 Hz with a ratio of minimum stress to maximum stress of R = -1.0. Tension-compression fatigue behavior was studied for fatigue stresses ranging from 80 to 300 MPa in air and in steam. Fatigue run-out was defined as 2x10璽 繕 cycles. Fatigue limit (based on a run-out condition of 2x10璽 繕 cycles) was 80 MPa in air and in steam. The presence of steam decreased the fatigue life of specimens tested above the fatigue limit. Specimens that achieved fatigue run-out were subjected to tensile tests to failure to characterize the retained tensile properties. The material retained 100% of its tensile strength. Reduction in tensile modulus was 68% while the change in compressive modulus was negligible.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Excel-Based Surveillance Planning and Scoring Tool for the Scud Hunting Mission
The research effort presented here is focused on the development of a basic mathematical model to simulate multiple sensors surveiling multiple targets akin to the scud-hunting problem which faced coalition forces during Operation DESERT STORM and Operation IRAQI FREEDOM. Drawing on similarities between the scud-hunting problem and the classical fractional knapsack problem, a greedy heuristic is employed in an attempt to maximize the overall surveillance contribution of each individual sensor. Using Microsoft Excel and Visual Basic for Applications (VBA), a model is constructed which builds sensor flight paths to maximize the overall surveillance effort from the group of sensors, scores the overall effectiveness of the surveillance effort, and provides this information to the analyst in a timely manner. Recommendations for further research to improve the utility of the model are included.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Fabrication and Evaluation of Graphite Fiber-Reinforced Polyimide Composite Tube Forms Using Modified Resin Transfer Molding
The techniques necessary for the fabrication of a complex three-dimensional tubular form using a PMR-type resin have been developed to allow for the construction of several tubes with good physical and mechanical properties. Employing established resin transfer molding practices, the relatively non-hazardous AMB-21 in acetone formulation was used to successfully impregnate four layers of AS4 braided graphite fiber preform previously loaded around an aluminum cylindrical core in an enclosed mold cavity. Using heat and vacuum, the solvent was evaporated to form a prepreg followed by a partial imidization and removal of condensation products. The aluminum core was replaced by a silicone rubber bladder and the cure cycle continued to the final stage of 550 F with a bladder internal pressure of 200 lbs/sq in while simultaneously applying a strong vacuum to the prepreg for removal of any additional imidization products. A combination of several modifications to the standard resin transfer molding methodology enabled the mold to 'breathe', allowing the imidization products a pathway for escape. AMB-21 resin was chosen because of the carcinogenic nature of the primary commercial polyimide PMR-15. The AMB-21 resin was formulated using commercially available monomers or monomer precursors and dissolved in a mixture of methyl alcohol and acetone. The viscosity of the resulting monomer solution was checked by use of a Brookfield rheometer and adjusted by adding acetone to an easily pumpable viscosity of about 600 cP. In addition, several types of chromatographic and thermal analyses were of the braids, and excess handling of the preforms broke some of the microscopic fibers, needlessly decreasing the strength of the finished part. In addition, three dimensional braided preforms with fibers along the length of the tube will be significantly stronger in tension than the braided preforms used in this study.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Directed Energy Weapon System for Ballistic Missile Defense
Ballistic missiles carrying nuclear weapons and the proliferation of nuclear weapons represent two of the gravest threats to the security of the United States, its service members, and allies. It may come as no surprise that the international threat environment the U.S. will face for many decades to come will be fundamentally different from the Cold War era and different from today's global fight against terrorist organizations and extremism. The list of global actors who possess ballistic missiles or seek to acquire the technology has grown exponentially over the years from a total of nine countries in 1972 to 33 countries today. Rogue states, chief among them North Korea and Iran, continue to place a premium on the acquisition of nuclear weapons technology and the platforms to delivery them. Both India and Pakistan have active nuclear programs and North Korea solidified its position in the world as a nuclear-capable state. While Russia contains that world's second largest nuclear stockpile, China possesses the world's most active ballistic missile development program.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Hypersonic Global Strike Feasibility and Options
This paper explores the feasibility of hypersonic weapons and aircraft as global strike options in the 2035 timeframe. The paper proposes there are currently two limitations or gaps in U.S. prompt global strike capabilities; timeliness, and increasingly the ability to gain access to the highly-defended target area. Additionally, the USAF has a long history of using advanced technology to stay ahead of the threat defense systems and gaining access to target sets, and by 2035, anti-access and area denial (A2/AD) technologies will increasingly threaten the USAF ability to hold any target on the globe at risk. Therefore, given the fact that technologies will continue developing to diminish and deny the advantages of stealth and space assets, could speed once again allow access to denied, heavily defended targets and close the gap for prompt global strike by 2035? The analysis begins with a brief overview of past hypersonic programs and reveals the lack of coherent government policy or USAF confidence in future military utility for hypersonic weapons or aircraft.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Combat Identification Modeling Using Neural Networks Techniques
The purposes of this research were: (1) validating Kim's (2007) simulation method by applying analytic methods and (2) comparing the two different Robust Parameter Design methods with three measures of performance (label accuracy for enemy, friendly, and clutter). Considering the features of CID, input variables were defined as two controllable (threshold combination of detector and classifier) and three uncontrollable (map size, number of enemies and friendly). The first set of experiments considers Kim's method using analytical methods. In order to create response variables, Kim's method uses Monte Carlo simulation. The output results showed no difference between simulation and the analytic method. The second set of experiments compared the measures of performance between a standard RPD used by Kim and a new method using Artificial Neural Networks (ANNs). To find optimal combinations of detection and classification thresholds, Kim's model uses regression with a combined array design, whereas the ANNs method uses ANN with a crossed array design. In the case of label accuracy for enemy, Kim's solution showed the higher expected value, however it also showed a higher variance. Additionally, the model's residuals were higher for Kim's model.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Where's My GPS?
The United States possesses the most powerful military force in the world and the underpinning for that force is provided by the ubiquity of Positioning, Navigation and Timing (PNT) systems; the United States Air Force's Global Positioning System (GPS) is by far the most prevalent. The vast majority of US combat systems and capabilities, including foundational capabilities such as global situational awareness and precision long-range strike, heavily leverage the capabilities provided by GPS. However, by integrating GPS into every significant combat system, it is argued that the USAF has inadvertently created a vulnerability that will be exploited by future foes. The USAF and our joint partners cannot afford to operate without GPS and PNT capability and therefore must learn to operate through GPS and PNT degradation. To do so, the USAF must develop and nurture across its core competencies two critical capabilities: the ability recognize a degraded PNT environment and the ability to successfully operate in said environs. The threat should not be over-stated but neither should decision-makers and leaders wish away the challenges presented by operations in PNT degraded environments. Rather, a combination of mitigations such as testing, exercises, training, policy changes, material solutions and operational tactics, techniques and procedures must all be synchronized in a manner that guarantees that US combat forces are equipped and trained to achieve mission success in all PNT environments.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Strikestar 2025
The United States military of the year 2025 will need to deal with a widevariety of threats in diverse parts of the world. It will be faced withbudgetary restraints that will dictate system trades favoring those militaryelements that offer utility over a wide spectrum of conflict and add to theability to project power over long distances. The United States military of the year 2025 will also exist in a social and political environment that willdictate the need to minimize United States personnel losses and enemy collateral damage.An opportunity exists to exploit planned advances in intelligence, surveillance, reconnaissance, and the development of unmanned aerial vehicles (UAV) to address future military needs. Through all-source, coordinated intelligence fusion, it will be possible to supply the war fighter with all-weather, day or night, near-perfect battlespace awareness. This information will be of precision targeting quality and takes advantage of multiple sources to create a multidimensional view of potential targets. Early in the twenty-first century, reconnaissance UAVs will mature to the extent that reliable, long-endurance, high-altitude flight will be routine, and multiple, secure command and control communications links to them will have been developed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Routing UAVS to Co-Optimize Mission Effectiveness and Network Performance With Dynamic Programming
In support of the Air Force Research Laboratory's (AFRL) vision of the layered sensing operations center, command and control intelligence surveillance and reconnaissance (C2ISR) more focus must be placed on architectures that support information systems, rather than just the information systems themselves. By extending the role of UAVs beyond simply intelligence, surveillance, and reconnaissance (ISR) operations and into a dual-role with networking operations we can better utilize our information assets. To achieve the goal of dual-role UAVs, a concrete approach to planning must be taken. This research defines a mathematical model and a non-trivial deterministic algorithmic approach to determining UAV placement to support ad-hoc network capability, while maintaining the valuable service of surveillance activities.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Measuring the Operational Readiness of an Air Force Network Warfare Squadron
As part of its squadron activation, the 315th Network Warfare Squadron (NWS) requested assistance from the Air Force Institute of Technology in developing criteria for declaring Initial Operational Capability (IOC) and Full Operational Capability (FOC) to assess the unit's operational readiness. The research methodology included a review of current Department of Defense (DoD), Joint, and Air Force publications and instructions, as well as a review of three different unit activations: the new Air Force Cyberspace Command, an F/A-22 Fighter Squadron, and an Intelligence Squadron. By comparing the Joint Capabilities Integration and Development System (JCIDS) process and the Status of Resources and Training System (SORTS) process, it is clear that unit readiness is measured and reported by SORTS Category Levels (C-Level) to support wartime missions, not by IOC and FOC milestones. This paper reviews SORTS computations and provides a case study of a notional Air Force NWS to propose that any new cyber squadron should report operational readiness starting with C-5 for unit activation, then C-3 to declare initial operational readiness, and finally C-1 to declare full wartime mission readiness.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Nanotechnology Weapons
Innovations from nanotechnology are starting to make their way into products on the commercial market as well as information and combat systems for the military. Improvements brought about by nanotechnology will be revolutionary, but, nanotechnology will also present entirely new threats. Steps must be taken now to address the asymmetrical menace posed by future nanotechnology weapons. Production rates of nanomaterials are also rising dramatically, yet there is a general lack of agreement and understanding about their dangers. Sometime within the next 5-10 years, development of a new type of chemical or biological weapon based on discoveries in nanotechnology could be a very real possibility, yet the Department of Defense (DOD) has not initiated programs to focus specifically on understanding or preventing this new type of threat. The DOD should take action now to solve the unknowns as it relates to the dangers of nanostructures, raise awareness on the dangers of nanotechnology within US research institutions and internationally alike, and introduce nanotechnology weapons into DOD educational environments and strategic planning.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Simulation Modeling and Analysis of TNMCS for the B-1 Strategic Bomber
Simulation provides a method of modeling complex systems which would otherwise be impractical for quantitative experimentation. While other analytic techniques have been used to explore Total Non-Mission Capable [due to] Supply (TNMCS) rates, simulation offers a novel approach to discovering what aspects of the supply chain impact this metric. This research develops a discrete event simulation to investigate factors which affect TNMCS rates for the B-1B by modeling the core processes within the Air Force (AF) supply chain. A notional fleet of 16 aircraft at a single air base (Ellsworth AFB, SD) is modeled based on historical supply and maintenance data. To identify and quantify the effects of various factors, an experimental design is used for analyzing the output of our high-level discrete event simulation. Additionally, two different approaches to reporting and modeling Air Logistics Center (ALC) stockage effectiveness (SE) are compared to our baseline simulation. This exploration shows several factors which significantly impact TNMCS rates and have the potential to reduce them to their current targets.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Thermal Characteristics of Pitch Based Carbon Foam and Phase Change Materials
Phase-change thermal energy storage devices offer thermal control systems an option that allows a smaller heat sink to be used by absorbing the thermal energy quickly and storing it in the phase change to prevent failure of electronic components and then slowly releasing the heat to the heat sink. This paper experimentally determined the transient response of carbon foam with a phase-change material by measuring the response to a step temperature input to test samples. The transient response was recorded until steady state was reached. An analytic response was created and compared against the measured response. A simplified analytic prediction of the transient response was developed by using an energy balance. This approximation was then compared against the experimental results.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Rapid Runway Repair
Minimum Operating Strip (MOS) selection determines the exact placement of the MOS on the damaged runway, and therefore, the amount of munitions that need to be neutralized and the amount of damage that will need to be repaired. MOS selection, in essence, is the key determinant of the time required to attain an operational takeoff and recovery surface. Since the MOS selection stage determines the events and scope of work for all of the Rapid Runway Repair (RRR) stages that follow, it could be argued that this is the most important stage in the entire RRR process. The primary purpose of this research was to evaluate the application of a decision analysis methodology for the selection of a MOS during the RRR process. The secondary purpose was to determine the effect of additional considerations on both the MOS selected and the repair time. MOSs selected utilizing the outlined methodology were compared to a MOS selected using the current USAF method. Results showed that additional considerations have an impact on both MOS selection and time to repair. Results also showed that the outlined methodology selected a MOS with a shorter repair time, despite additional damage, than the MOS selected using the current USAF method.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The purpose of this research effort is to investigate and analyze high energy laser and high power microwave directed energy technologies that could enhance special operations forces (SOF) warfighting capabilities within the next 10-15 years. The primary objective of this paper is to present an assessment of the potential military utility of these technologies in support of SOF warfighting roles and missions. The intent of this paper is to offer a broad, strategic perspective on the ways in which directed energy technologies could transform the conduct of future special operations missions. Since the end of the Cold War, the Department of Defense (DOD) has embarked upon a number of efforts to reshape America's armed forces to meet a new set of security challenges. The process of re-tooling our armed forces has been an iterative one, and continues today under the banner of "defense transformation." This paper explores the concept of defense transformation, how directed energy technologies align with DOD transformation constructs, and how they might, or might not, support SOF transformation objectives and future warfighting requirements. To do this, operational measures of effectiveness (MOEs) are derived from various DOD, Air Force, and SOF transformation roadmaps, as well as Air Force and USSOCOM concepts of operation. Using these MOEs as a framework for analysis, this paper presents an assessment of the potential military utility and transformational value of directed energy technologies that could, one day, be developed into air-to-ground weapons for use by SOF strike platforms.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Estimating the Effects of Radio Frequency Identification Tagging Technologies on the Army's War-Time Logistics Network
Some civilian business practices, such as radio frequency identification (RFID) tags, were used for the first time by the Army in a major conflict during Operation Iraqi Freedom (OIF). RFID tags were attached to every container and pallet in all sustainment shipments entering and exiting the area of operations (AOR). Although RFID tagging was somewhat successful during OIF, the logistics network still suffered significant problems, to include lack of asset visibility and ineffective theater distribution. Implementing business practices on the battlefield seems like an easy answer to these problems, but the implementation of RFID tags may or may not easily transition to a military of combat environment. The purpose of this research was to discover if the business practice of using RFID tags to track equipment and supplies could be effectively used in a war-time environment by the Army's logistics network.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Behavior of Three Metallic Alloys Under Combined Axial-Shear Stress at 650 C
Three materials, Inconel 718, Haynes 188, and 316 stainless steel, were tested under an axial-torsional stress state at 650 C. The objective of this study was to quantify the evolution of the material while in the viscoplastic domain. Initial and subsequent yield surfaces were experimentally determined to quantify hardening. Subsequent yield surfaces (yield surfaces taken after a preload) had a well-defined front side, in the prestrain direction, but a poorly defined back side, opposite the prestrain direction. Subsequent yield surfaces exhibited isotropic hardening by expansion of the yield surface, kinematic hardening by translation of the yield surface, and distortional hardening by flattening of the yield surface in the direction opposite to the last prestrain. An existing yield function capable of representing isotropic, kinematic, and distortional hardening was used to fit each yield surface. Four variables are used to describe each surface. These variables evolve as the material state changes and have been regressed to the yield surface data.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Oxidation Kinetics of Continuous Carbon Fibers in a Cracked Ceramic Matrix Composite
Experimental observations and results suggest two primary regimes as a function of temperature, i.e., diffusion and reaction controlled kinetics. Thermogravimetric analysis of carbon fiber in flowing oxygen gave an activation energy of 64.1 kJ/mol in the temperature range of 500 to 600 C and an apparent activation energy of 7.6 kJ/mol for temperatures from 600 to 1400 C. When C/SiC composite material was unstressed, matrix effects at temperatures from 900 to 1400 C protected the internal fibers. When under stress, self-protection was not observed. Increasing the stress from 10 to 25 ksi caused a 67 to 82 percent reduction in times to failure at temperatures from 750 to 1500 C. Based on experimental results, observation, and theory, a finite difference model was developed, which simulates the diffusion of oxygen into a matrix crack that is bridged by carbon fibers. The model allows the influence of important variables on oxidation kinetics to be studied systematically, i.e., temperature, reaction rate constant, diffusion coefficient, environment, and sample geometry.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Guide to the Biosolids Risk Assessments for the EPA Part 503 Rule
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Prediction of Long-Term Strength of Thermoplastic Composites Using Time-Temperature Superposition
Accelerated tests for composite failure were investigated. Constant ramp transverse strength tests on thermoplastic composite specimens were conducted at four temperatures from 300 F to 450 F and five duration times from 0.5 sec to 24 hrs. Up to 400 F, the time-temperature-superposition method produces a master curve allowing strength at longer times to be estimated from strength tests conducted over shorter times but at higher temperatures. The shift factors derived from compliance tests applied well to the strength data. To explain why strength behaved similar to compliance, a viscoelastic fracture model was investigated based on the hypothesis that the work of fracture for crack initiation at some critical flaw remains constant with time and temperature. The model, which used compliance as input, was found to fit the strength data only if the critical fracture energy was allowed to vary with stress rate. Fracture tests using double cantilever beam specimens were conducted from 300 F to 450 F over time scales similar to the strength study. The toughness data showed a significant change with loading rate, less variation with temperature, did not form a master curve, and could not be correlated with the fracture model. Since the fracture model did not fit the fracture data, an alternative explanation based on the dilatational strain energy density was proposed. However the usefulness of this model is severely limited because it relies on a critical parameter which varies with loading rate.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Prepositioned Trailers for Aircraft Battle Damage Repair Support
Air superiority is essential in today's wartime environment. Aircraft that are damaged and not returned to combat can have a considerable impact on the quest for dominance in the air. To maintain operational effectiveness, an organization must have the capability to quickly repair damaged aircraft. The purpose of an Aircraft Battle Damage Repair (ABDR) program is to rapidly and effectively repair damaged aircraft to fly additional operational sorties and further contribute to wartime objectives. This capability must consist of providing the necessary tools and equipment for the rapid repair of aircraft. When an ABDR team deploys in support of an organization in a wartime environment, it is expected that the team will be fully functional, autonomous, and have on hand the resources necessary to complete all tasks. From a logistics standpoint, this is a feasible objective using different methods, with the present method used being prepositioning. During combat operations, Air Mobility Command (AMC) is heavily tasked with movement of personnel and equipment. The prepositioning of ABDR trailers could provide relief on AMC resources already strained to their limits. This research seeks to determine if the AF should continue to preposition ABDR trailers to augment strategic airlift during combat operations by determining the best course of action for providing ABDR trailers to ABDR teams during combat operations. This research will evaluate the effectiveness of both prepositioning and airlifting ABDR trailers.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Minimizing the Risks of Diminishing Manufacturing Sources and Material Shortages
The Air Force faces increasingly difficult challenges to maintain and sustain its highly technical weapon systems, struggling against rapid technology advancement and diminishing lifecycle for electronic systems. The reduced lifecycle times have not only complicated sustainment, the lifecycles have diminished to the point that new military aircraft designs face challenges of obsolescence within the manufacturing cycle, and in some cases before manufacturing even begins. This research project explores Diminishing Manufacturing Sources and Material Shortages (DMSMS) and obsolescence cost associated with electronic avionic components. The overall research question asks how obsolescence management can be improved in the Air Force. This project utilizes two integrated models, the first, to determine electronic avionics demand requirements for a fleet of 96 aircraft over a 30-year period, and the second, to evaluate sustainment cost over time for a) re-engineering strategy, b) lifetime buy strategy, and c) programmed redesign strategy. Statistical analysis and long-term cost comparison of these three strategies will provide a framework to evaluate specific weapon systems for future studies and to develop an attainable low-cost sustainment strategy.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Rapid Prototyping, Acquisition and Deployment of Technology Pushed Weapon Systems Using Nontraditional Acquisition Processes
With the explosion of technology driven systems and their ability to effectively meet military operational need it is imperative we in the acquisition community have the ability to rapidly acquire, deploy and support these potential life saving technological advancements. This paper will explore five non-traditional acquisition processes and use case studies to clarify and outline a defined process to best get new technology into the operators' hands in the most time efficient manner possible. This paper includes a description of the traditional acquisition process, five non-traditional acquisition processes, and the criteria a program must meet to gain access to these processes. The culmination of this effort is the identification and development of a rapid technology pushed weapon system acquisition and deployment checklist/process, and lessons learned from the Project Angel Fire and Predator case studies.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Passive Geolocation of Low-Power Emitters in Urban Environments Using TDOA
Low-power devices such as key fobs, cell phones, and wireless routers are commonly used to control Improvised Explosive Devices (IEDs) and as communications nodes for command and control. Quickly locating the source of these signals is difficult, especially in an urban environment where buildings and towers can cause interference. This research presents a geolocation system that combines the attributes of several proven geolocation and error mitigation methods to locate an emitter of interest in an urban environment. The proposed geolocation system uses a Time Difference of Arrival (TDOA) technique to estimate the location of the emitter of interest. Using multiple sensors at known locations, TDOA estimates are obtained by cross-correlating the signal received at all the sensors. A Weighted Least Squares (WLS) solution is used to estimate the emitter's location.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Analysis of the Potential for Using Over-The-Horizon Radar Systems for Space Surveillance
The Australian Defence Force is investigating the development of a space surveillance system. While several dedicated facilities for space surveillance are in operation around the world, Australia's Over-The-Horizon Radar (OTHR) network has some potential for this role. The OTHR operates in the HF band and is constrained by the propagation effects of the ionosphere. A spherically stratified ionospheric model and a model for a nominal OTHR antenna are developed that allow calculation of path propagation, power distribution, and clutter returns. A software-based radar receiver processing system is modeled to determine detection probabilities and the minimum detectable radar cross-section of targets in typical low earth orbit (LEO) trajectories. The high clutter power levels, coupled with long target ranges and high velocities, mean that range-Doppler tradeoffs have a great impact on the resulting detection capabilities. While the system as modeled has the potential to provide some coverage for LEO targets, operational constraints mean the necessary conditions for detection of space targets would rarely be met while the system is involved in traditional OTHR tasking. Further, the long wavelengths and large antenna beams mean the accuracy of any positioning information is low.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Improving the Estimation of the Military Worth of the Advanced Tactical Laser Through Simulation Aggregation
Fielding High Energy Laser (HEL) weapon systems presents technological challenges as well as employment and financial challenges. The risk associated with the challenges mandates the development process include computer simulation models capable of predicting weapon system performance from the engineering level to assessing the military worth of employing HEL systems in combat scenarios. This research effort focuses on developing laser performance data at a higher fidelity engagement model and integrating the performance data into a mission level model. The propagation of the laser from the transmitting aperture to the target is modeled at the engagement level through the employment of the High Energy Laser End-to-End Operational Simulation (HELEEOS), developed by the AFIT Center for Directed Energy (CDE).This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Achieving Decision Making Superiority
The USAF is making a commitment to dominate the cyberspace domain in the same manner it dominates the air and space domains. This commitment comes during a time of accelerating growth in technology. If the current acceleration in technology continues, by the year 2025 defending U.S. cyberspace equity will require speed only available through automation of our cyber systems and decision making processes. To fly, fight and win in cyberspace the USAF should prepare for an OODA loop (observe, orient, decide, and act) measured in microseconds. Who will harness the capabilities of the cyber domain and integrate them with existing air and space capabilities? The infrastructure to protect our networks exists, but where is the cadre of cyber warriors (CW) to be educated? The accelerating pace of change in cyber technology brings new capabilities and increased availability for all players from nation states to small terrorist cells and criminals. This paper examines the need for the USAF to combine the specialized skills of CW with tactical genius and a warrior culture in a Cyber Weapons School (CWS).This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Theater Space Warfare
Theater space warfare is emerging from two streams of evolution in military space: the role of space in military operations and the role of the theater in space operations. Indispensable at the strategic level throughout the Cold War, space is now proving indispensable at the operational and tactical level. As the incorporation of space into warfare accelerates over the next decade, the concept of space-enabled warfare puts a premium on access to space and effective integration into joint operations. The role of the theater in space operations is also evolving, from passive consumer to that of an active consumer and producer of space effects. Microsatellites, near-space assets, and adversary satellite jammers all necessitate active theater participation in space operations. Unfortunately, today's joint doctrine has missed this on-going evolution, leaving the US military ill prepared to optimize space across joint operations.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Stealth
This paper traces the development of stealth as an example of the way in which technology is invented, selected, acquired, and employed by the U.S. Armed Forces. The relationship between technology and the American culture that uses it is the foundation of the discussion. Stealth, as a specific technology, is traced from the prominent position of technology in the American way of war through its employment on the battlefield in Operation DESERT STORM. Lessons from this development highlight the different levels of success achieved by the American way of war as contrasted to the American way of acquisition. Finally, doctrine technology application, future opportunities, and limitations are explored in an effort to flesh out a comprehensive view of how the development of stealth contributed to the American way of war and what lessons can be applied to the key supporting element, the American way of acquisition. The apparent effectiveness of the application of stealth technologies should not imply that the same level of success was achieved in the acquisition of those technologies. The seemingly unplanned convergence of basic research, a well understood requirement, a number of supporting technologies, and the right entrepreneur is compared to a robust application of stealth technology to combat through the medium of doctrine. The author concludes that doctrine does not have the same effect on the technology process selection as it has on its application and that the importance of the human element to technology development has not diminished, but continues to grow.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Nanotechnology
Numerous technological changes have taken place in the last 50 years; many of them were considered science fiction in the twentieth century. Geoffrey Hunt and Michael Mehta said nanotechnologies are making the jump from science fiction to science reality.1 Popular science fiction author Michael Crichton has written two best seller novels that include a discussion of nanotechnology and future possibilities. Nanotechnology is actually a family of nanoscale technologies and is a swiftly rising field whose dynamics and forecast pose many challenges not only to scientists and engineers but also to society at large. This Nanotechnology covers a broad assortment of procedures and uses that will make some products better, cheaper, and faster, and it will enable the creation of products and applications that are currently beyond our ability to envision. Although many have called nanotechnology the next industrial revolution, much research needs to be done to ensure the future safety of the world and the human race due to the use of this revolutionary technology at the nanoscale.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Unmanned Combat Aerial Vehicles
With the success of Unmanned Aerial Vehicles (UAV) in Operations Allied Force, Enduring Freedom, and Iraqi Freedom, many in Congress and DoD are pushing to put more UAV capability on the battlefield of tomorrow. More importantly, the desire is to have these UAVs shift from reconnaissance to offensive combat platforms commonly referred to as UCAVs (Unmanned Combat Aerial Vehicles). UCAV's first mission is Suppression of Enemy Air Defenses (SEAD) and its complementary mission of Electronic Warfare (EW) sometimes referred to as jamming. Early support for these particular missions can be traced to a couple of factors. The first is the need to supplement and eventually replace the current Low Density/High Demand (LD/HD) manned systems such as the F-16CJ for SEAD and the EA-6B for EW. While these assets are limited in quantity, they are also artificially limited in employment capability due to concern for the aircrew in the dangerous environment in which they are forced to operate. This paper investigates the UCAV alternatives, to include sensor and weapon technology, and then recommends a course of action. The challenges of making a UCAV that can do the same job as a manned aircraft cheaper and more effectively will be the key drivers in deciding whether this is the right direction.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Short Takeoff Vertical Land (STOVL) technology existed for high-performance aircraft since the late 1960s, but the United States Air Force (USAF) elected not to acquire a STOVL fighter despite the United States Marine Corp (USMC) and coalition partners such as Great Britain and Italy investing in such fighters. The former Chief of Staff of the Air Force (CSAF) stated the USAF is interested in acquiring a STOVL variant (designated as the F-35B) of the Joint Strike Fighter (JSF) in addition to the F-35A, the USAF JSF variant.1 To date, the current CSAF has not reversed this decision but this may be due to the absence of a study that clearly states the advantages and disadvantages of the F-35B for the USAF. The USAF still needs a research project to examine this subject and clearly state the pros and cons.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Space 2035
Space capabilities are vital to United States national power, commerce, science, and prestige. These capabilities will grow even more vital to the United States' and the global economy by 2035. What will the space technology and operating environment look like in 2035? Technology trends in two fundamental areas -- spacecraft and space transportation -- indicate space technologies, capabilities, products, and services will become far more affordable, ubiquitous, globally available, and interconnected. By 2035, the Space Cloud will emerge. Analogous to the network model of cloud computing, the primary nodes of the Space Cloud will be globally accessible, space-based, have access to virtually limitless solar power resources, possess a global high altitude field of regard, and will be both distributed and collaborative.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Slimeball
To date, the development of non-lethal weapons (NLW) has concentrated on one-on-one applications and other small, tightly controlled situations. The development of broader scale NLW has lagged, however, even though the technical barriers to their employment do not appear to be insurmountable. In the maritime domain, in particular, making NLW available to decision makers could have decisive effects in a variety of potential and very real situations. "The Slimeball" is a two-part weapon system consisting of a floating sticky foam barrier that will resist attempts to remove it, and a submerged gel barrier that will impede movement through a ship channel. The parts can also be used independently of each other, depending on the type of munitions used to deliver the material and the desired effects. The primary consideration for successfully employing the system is to only use it in facilities that are sheltered from open water and exhibit restricted waterways, such as jetty-protected harbors or underground facilities with narrow adits. The individual components of the Slimeball already exist or can be manufactured to designers' specifications, and some are even commercially available, but to date they have not been combined in the manner described here.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Transforming U.S. Air Force Enlisted Aircraft Maintenance Training
How can the United States Air Force transform the way it trains a new generation of enlisted aircraft maintainers to support modern weapon systems despite a diminishing workforce? Infusing the latest commercial 3-D interactive computer technology into Air Force enlisted maintenance training programs capitalizes on the current generation's inherent technical skills, prepares them to work on advanced aircraft systems and saves scarce resources. From 1996 through 2003 the Air Force Audit Agency evaluated aircraft maintenance training in the Air National Guard, Air Force Reserve and active duty units and found all three require drastic improvements. An analysis of Bloom's Taxonomy on the cognitive, affective and psychomotor learning domains sets the groundwork for how the proliferation of computer technology improves knowledge, attitude and skills for young aircraft maintainers. The overall result is a transformation from antiquated classrooms used by previous generations to a digital classroom of the future that focuses on existing computer technologies. High-tech, interactive computer systems transform the way a new generation of Airmen learn aircraft systems and maintenance procedures. The Air Force produces a better trained maintenance workforce by slashing classroom time, increasing aircraft system knowledge and fostering greater interest in training.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Assessing the US's Current Ability to Understand and Test EMP Effects on Systems
During the Cold War, the United States as a nation, and its military in particular, were very focused on nuclear warfighting. After winning the Cold War this focus became significantly lessened. However, in the past decade new concerns have arisen and it is once again realistic to think that the US military might have to operate in a nuclear environment. The one nuclear effect with the possibility to effect very large areas almost immediately after a nuclear explosion is the electromagnetic pulse (EMP). The EMP has the ability to affect any system which is or is composed of electronics or conductive media (e.g., metal). As the most advanced military in the world, the US military is highly dependent upon advanced electronic systems to operate. By obtaining a better understanding of how an EMP is formed and propagated and then affects systems, the military can better design, test, and certify its systems to ensure that they are capable of operating in an EMP environment, and the better understanding will enable this to be done in a cost-effective manner. This paper shall look at what we know about EMP, the facilities and resources we have for improving that understanding, and make some recommendations for how to best move forward with future programs.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Airborne Laser and the Future of Theater Missile Defense
The theater ballistic missile (TBM) problem encountered in the Persian Gulf War revealed an alarming deficiency in US defenses. This paper takes a brief look at the major theater missile defense (TMD) systems in use and under development by the US today. Second, it focuses on the performance of the Army's Patriot defense system in the Gulf War. Finally, the paper offers an in-depth look at the development of the Airborne Laser (ABL) and how it should fit into an overall national structure for TMD. The paper concludes that Patriot performance in the Gulf war was unsatisfactory, not just because of system flaws, but because of the concept of point defense itself. The ABL provides a unique solution to collateral damage inherent in point defense concepts. In addition, the ABL can provide advanced warning to other theater defense systems in the event of a mass launch which could overtax the ABL's capabilities. The paper offers several recommendations for the future direction of TMD. First, phase out point defense completely and channel those funds into development of the other TMD systems which minimize collateral damage to the assets they are intended to protect. Second, expedite development of the ABL as the first line of TMD, backed up by long-range theater systems. Third, continue to develop true theater defense systems; that is, systems which have a range of hundreds of kilometers such as the Navy's Aegis and the Army's THAAD systems, preventing TBMs from getting close to their intended target.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Persistent Space Situational Awareness
In the decades since the space program first began, the United States has become more and more dependent on space across a broad spectrum of military, commercial, and civil applications. That dependence brings with it an inherent vulnerability, and recent evidence of the growing threat, combined with acknowledged gaps that exist in our ability to rapidly characterize and attribute attacks on our satellites results in a compelling need for a robust space situational awareness (SSA) capability. The Distributed Real-time Awareness Global Network in Space (DRAGNETS) is one solution that leverages the trend toward distributed, networked military capabilities that nanotechnology will enable within the next 20 years. The DRAGNETS approach uses distributed constellations of thousands of very small sugar cube-sized femtosats to maintain continual cognizance of the space environment. Current and future advances in nanotechnology will lead to substantial miniaturization of satellite functions and allow the Air Force to field flexible, adaptive, and responsive systems as part of an overall SSA architecture. In order to realize the DRAGNETS vision, the Air Force should plan phased investments leading to an operational assessment of a prototype DRAGNETS constellation at a technology readiness level of 7 by 2025. The end result will be a capability that, when integrated with existing ground and space-based SSA assets, provides Combatant Commanders and senior decision makers with the necessary awareness to preserve maximum flexibility in the use of US space capabilities.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
