Exploitation of Self Organization in UAV Swarms for Optimization in Combat Environments
This investigation focuses primarily on the development of effective target engagement for unmanned aerial vehicle (UAV) swarms using autonomous selforganized cooperative control. This development required the design of a new abstract UAV swarm control model which flows from an abstract Markov structure, a Partially Observable Markov Decision Process. Self-organization features, bio-inspired attack concepts, evolutionary computation (multi-objective genetic algorithms, differential evolution), and feedback from environmental awareness are instantiated within this model. The associated decomposition technique focuses on the iterative deconstruction of the problem domain state and dynamically building-up of self organizational rules as related to the problem domain environment. Resulting emergent behaviors provide the appropriate but different dynamic activity of each UAV agent for statistically accomplishing the required multi-agent temporal attack task. The current application implementing this architecture involves both UAV flight formation behaviors and UAVs attacking targets in hostile environments. This temporal application has been quite successful in computational simulation (animation) with supporting statistical analysis.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

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.

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.

Put the Joint Back in the Joint Strike Fighter
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.

Airborne Platforms for Emergency Communications and Reconnaissance in Domestic Disaster Response
Since the 19th century, aircraft have played a significant role in military operations worldwide. From the use of observation balloons in the American Civil War, to the introduction of jet-powered aircraft in World War II, to the advent of remotely piloted aircraft (RPA) like the Reaper and Global Hawk, the role of aircraft has been ever expanding as technology advances in our nation's Air Force. One of the initial roles of military of aircraft was to provide intelligence, surveillance and reconnaissance (ISR) to battlefield commanders. That role continues today in a variety of situations. One of those situations is disaster response in the continental United States. US Air Force aircraft and sensor technology can provide detailed imagery and video of affected areas to assist with relief efforts. These aircraft can also be used to assist in another critical area of disaster response: communications restoral. Multi-role aircraft, manned, unmanned, and remotely piloted can be used to provide this ISR capability and provide communications service to an area affected by a disaster. Responding to a US Northern Command requirement, this research paper will explore which types of airborne platforms, to include airships, tethered aerostats, traditional heavier than air remotely piloted platforms, and others, can provide emergency communications and wide area surveillance both prior to a disaster situation, and during the US Government's response operations. The US Government response to Hurricane Katrina will be used as a case study to determine exactly what communications and ISR capabilities will be required to support disaster response operations. Lessons learned from Hurricane Katrina will also be explored.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Taking the Initiative
The 2001 Report of the Commission to Assess United States National Security Space Management and Organization stated that the United States is an attractive candidate for a "Space Pearl Harbor," and cited several vulnerabilities to include satellite malfunction, ground station equipment failures, hackers, as well as the Chinese threat. In June 2010, President Obama's National Space Policy of the United States of America established several principles, including one which states that the U.S. "will employ a variety of measures to help assure the use of space for all responsible parties, anddeter others from interference and attack." This is a complex and multi-faceted task, and there are several challenges associated with protecting US space systems, to include the assignment of a party responsible for protection and surveillance, vesting that agency with the necessary authority, training personnel in the importance of protecting space assets, and developing a comprehensive operational picture that provides sufficient granularity to not only prevent an attack, but should an attack occur, attribute it to the responsible party. This challenge is further exacerbated by the need to include a wide variety of agencies with numerous goals and cultures in any protection/surveillance schema.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Weaponeering the Future
Direct Energy weapons can exist on the battlefield of today. Yet, the warfighter needs to know what Probability of Damage theses weapons can attain. Currently, the Joint Munitions Effectiveness Manual calculates a Single Sortie Probability of Damage for conventional Blast and Fragmentation weapons. Using Futures Research methodology allows determination of what effects Direct Energy weapons will impart in the year 2035. The Status of Futures Index (SoFI) method compares complex entities to one another across multiple dimensions. Adapting the Single Sortie Probability of Damage formula for Lasers, Microwave and Millimeter wave weapons allows a determination of their effectiveness. The required formulas for each type of Direct Energy Weapons' Probability of Damage (or Effect) are derived and explained. The Direct Energy weapons are compared to both conventional weapons and one another. Adjusting these Probability equations adjusted for various inputs enables a forecast of the future capabilities of each weapon. The current trend trajectory establishes a baseline estimate of future Probabilities of Effect. Then, disruptive technologies are analyzed for their effect on the weapons capabilities. Each type of weapon poses a unique challenge. For Laser to match the capabilities of Blast/Fragmentation weapons, the power output must be increased. Microwaves, not only require increases in power, but also advances in antenna technology. Millimeter wave weapons can currently produce the required power, but manufacturing the weapons proves an obstacle. To overcome these difficulties, new technologies must be pursued. The SoFI method allows continuous evaluation of progress toward the goal of effective Direct Energy Weapons.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Employment of Unmanned Aircraft Systems for Canadian Forces Anti-Submarine Warfare
Fixed-wing Unmanned Aircraft Systems (UAS) technology has experienced exponential growth over the past 10-15 years and is now employed as an intelligence, surveillance, and reconnaissance (ISR) asset by virtually every modern military force in the world, as well as by civil law enforcement agencies. Currently, more than 30 nations are developing or manufacturing more than 250 models of UAS. Substantial commercial market growth and competition in fixed wing UAS platforms for military and law enforcement applications resulted in a wide variety of UAS platforms from small, hand-launched aircraft that operate at low altitudes for short-duration, to large, complex turbo-prop and jet powered aircraft capable of long-endurance operations at medium and high altitudes. Employment of Medium-Altitude, Long-Endurance (MALE) and High-Altitude, Long Endurance (HALE) UAS in the anti-submarine warfare (ASW) role is rapidly becoming feasible through emerging technologies and expanded payload capacities, the most significant of which are secure high-bandwidth Beyond Line of Sight (BLOS) satellite datalink communications, miniature light-weight sonobuoys, and real-time shore-based acoustic processing. As a result, UAS may be a technically feasible future Canadian Forces (CF) ASW capability as a complementary or stand-alone alternative to manned fixed-wing and rotary-wing maritime ASW 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.

The Last Manned Fighter
This research paper addresses the question of: Can and should the Air Force pursue a unmanned multi-role fighter to replace manned systems? Unmanned aircraft systems (UAS) have demonstrated enormous intelligence, surveillance, reconnaissance (ISR) capabilities in both flexibility and persistence. Current and emerging technology may permit unmanned fighters to replace conventional multi-role aircraft in the face of high endurance missions, evolving threat systems and political pressure to preserve human life. This research is framed in the context of a specialized weapon in military aviation; an unmanned multi-role fighter capable of replacing manned systems and their respective missions. This paper gives a brief history of unmanned air vehicles and their employment as weapons to demonstrate the evolution from ISR platform to unmanned combat air vehicle, then evolves into two main sections of "can we" and "should we" pursue this avenue of development. The primary means of answering the research question is both technical and philosophical. Before being able to answer if the Air Force should pursue an unmanned fighter it is necessary to determine if it is technically feasible for such a system.

Spectrum Management
As recently as September 2007, Deputy Secretary of Defense Gordon England directed the establishment of a task force to coordinate unmanned aircraft systems (UAS) issues and determine a way ahead to provide for "common, joint, and operationally effective UAS programs."1 Aren't the systems we have now common, joint, and operationally effective? Why the need for a task force and why did he mention specific areas to address including streamlining acquisition and management, interoperability, integration of UAS into civil airspace, frequency spectrum and bandwidth use, and payload and sensor management?2 The answers are not easy ones, but mainly concern the issue of increasing demand for these systems and their products, and the current existing challenges. The communications area of frequency and bandwidth availability is one case where these challenges will continue to increase as demand increases.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Sleep Deprivation and Its Effect on Combat Effectiveness
This paper examines the effects of sleep loss on the combat effectiveness of the US Army's leaders and soldiers. It begins with an examination of US and Soviet doctrine for conducting continuous operations. This section discusses the doctrinal methods and procedures that both major powers employ to maintain continuous pressure on their opponent. After laying the theoretical groundwork, it then examines the changes that have occurred in tactical force design since World War II to determine what has been done to enhance or degrade our ability to execute that doctrine. After this discussion on the mechanical aspect of combat, the paper discusses the effects of sleep loss on units and the individual soldier. It concludes that the US Army currently has no doctrine for the conduct of combat over an extended period of time. Adequate doctrine has been provided for the conduct of operations in periods of both limited and unlimited visibility, but the doctrine necessary to transition to continuous operations is not available. Furthermore, recent changes in the force structure of our combat units (primarily Armor and Mechanized Infantry) have significantly reduced the redundancy and robustness in those units that is necessary to conduct continuous operations. During continuous operations our units will be affected by loss of sleep. Sleep deprivation affects the cognitive skills of our leaders greater than the physical skills of our soldiers. To fight the continuous operations that will be forced upon us by our opponent, we must prepare ourselves to combat the effects of sleep loss first.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Upon This Rock
The use of space permeates all aspects of the American way of life. If the U.S. is to protect its space capabilities, it must increase its space situational awareness (SSA) to provide the foundation for activities in space. In the year 2030, congestion will describe the space environment. Space debris will be abundant, and satellite size will diminish through technology proliferation. The Air Force, as the Executive Agent for Space, will need to diagnose and attribute space events to meet this threat; however, current radar and optical telescopes cannot resolve these small objects.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Force-Multiplier for the F-15C
The Joint Tactical Information Distribution System (JTIDS) data link for the F-15C is a force-multiplier for the year 2000 and beyond. The Department of Defense must commit the funds to this critical program now. It will enable the USAF to gain and maintain air superiority over enemy airspace even with the dwindling numbers of airframes left in the inventory. The operational F-15C is over 20 years old and has had many major upgrades to the basic platform to extend and enhance its superiority over any potential opponent. The USAF must be allowed to purchase JTIDS for its F-15C's to preserve air superiority over future battlefields. The critical operational issues that must be addressed when evaluating an upgrade as a force-multiplier are: is mission effectiveness increased, is situational awareness increased, is mutual support enhanced, and is it interoperable with other C4I systems?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 Undersea Vehicles and Guided Missile Submarines
During the Cold War the United States developed the Trident class ballistic missile submarine (SSBN) to replace the aging fleet of forty-one Poseidon ballistic missile submarines. Each of the eighteen Trident class submarines built to carry the mantle of strategic nuclear deterrence was extremely large and quiet with tubes for twenty-four ballistic missiles. Following the breakup of the Soviet Union and the end of the Cold War, the United States conducted a review of its nuclear posture, which determined that only fourteen of these submarines were necessary to meet the needs of U.S. national security.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

JSTARS, E-10A and the Kill Chain
This research paper examines the Joint Surveillance Target Attack Radar System (JSTARS), its successes and shortfalls, its eventual replacement, the E-10A, and how both fit into the Find, Fix, Track, Target, Engage, and Assess (F2T2EA) Kill Chain construct for Effects-Based Operations in a Network-Centric environment. Information Superiority is a key enabler for dominance of the 21st Century battlespace. To this end, sensor-to-shooter operations are crucial for timely enemy force attrition. JSTARS' ability to conduct Intelligence, Surveillance, and Reconnaissance (ISR) as well as command and control operations is a lynchpin to providing the Joint Force Commander the predictive battlespace awareness (PBA) necessary for combat operations. Despite limitations in training, joint force education and experience, and its utilization in the Kill Chain, JSTARS' role will only increase in importance and expand with the fielding of the E-10A aircraft to provide real-time ISR and Battle Management Command and Control (BMC2) support to the Joint Force Commander.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Impact of Weapon System Complexity on Systems Acquisition
This paper reviews the previous use of the term complexity with respect to weapon systems. It then moves past these dated inferences that weapon system complexity is merely a synonym for cost or technical challenge and establishes a formal definition of complexity based on the interactions between the entities comprising the system. Due to difficulties in direct measurement of interactions, an equation is introduced to calculate the theoretical maximum number of interactions and to use this as the measurement of complexity. Based on this definition, analysis of data for aircraft avionics and airborne reconnaissance sensors suggests convincingly that system complexity is indeed increasing exponentially. Increasing complexity can be linked to system development cost and schedule and production cost as previously inferred by at least some researchers. No single solution exists for addressing this trend of increasing complexity. Attempts can be made to either limit the amount of complexity of future weapon systems while still providing adequate performance increases or to better cope with complexity. In regard to the latter, it has been suggested that acquisition is analogous to Clausewitzian warfare in some key respects and that the cultivation of acquisition genius should be pursued in like manner to the cultivation of war genius.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Tactical Reconnaissance
Ever since the Isrealis demonstrated how Unmanned Aerial Vehicles (UAVs) could be effectively used in operations, interest in UAVs has intensified. Following their successful employment on the battlefield in Desert Storm, technology has driven the development of more capable UAVs. The major improvements in UAVs in recent years have been in the role of tactical reconnaissance. In this role the UAV has significant capabilities to offer, some that are unmatched by other platforms. This paper will demonstrate that with the growing importance of information in warfare the UAV is suited to fill the information gap on the battlefield. The doctrine for UAV operations has not kept pace with the fast paced developments in this field. Their organization also needs to break out of the traditional mind-set. When employed in an efficient manner, the inherent qualities of expendability and low cost make the UAV capable of significantly complementing manned aircraft platforms in the role of tactical reconnaissance.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Deux Ex Machina
With the rapid growth of communication and computational capacity, one area of the military that is an obvious candidate for transformation is command and control (C2). Network Centric Warfare (NCW) advocates believe that linked sensors, shooters, and decision makers will be able to plan and execute combat action more rapidly and more effectively than non-linked units. Skeptics of NCW believe it has the potential to place too much emphasis on the technical and tactical aspects of warfare. Another potential weakness of the NCW concept is information overload at all levels of command. Sensor fusion is a method of using computer algorithms to combine information from various sensors into one track to reduce information overload. Sensor fusion algorithms may combine discrete tracks or may combine measurements from two or more sensors. Sensor fusion may involve input from similar sensors, such as two radars, or dissimilar sensors such as a radar and a forward looking infrared (FLIR).This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Integrating the B-2 Into Link 16 Operations
Network centric warfare is a key enabler to present day military operations. Link 16, a tactical data link, is one means that combat air forces utilize to leverage network centric warfare. In the past, the B-2 community relied on stove-piped communications systems, but now the B-2 is in the early stages of implementing a fully integrated Link 16 system. This paper will show that the current integration of Link 16 will enhance the B-2's overall mission effectiveness by decreasing aircrew workload, increasing situational awareness, and eliminating many opportunities for human error. However, the current Link 16 implementation also has several hurdles to overcome in order to be fully effective. These hurdles, which include implementing hardware and software improvements, maximizing training opportunities, and emphasizing a commitment to Link 16 use in combat operations, are also addressed.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
