To accomplish this, two different MODAS fields were used by the Weapon Acoustic Preset Program (WAPP) to determine suggested presets for a Mk 48 variant torpedo. The MODAS fields differ in that one uses altimeter data assimilated from three satellites while the other uses no altimeter data. The metric used to compare the two sets of outputs is the relative difference in acoustic coverage area generated by WAPP. Output presets are created for five different scenarios, two Anti- Surface Warfare scenarios and three Anti-Submarine Warfare scenarios, in each of three regions: the East China Sea, the Sea of Japan, and an area south of Japan that includes the Kuroshio current. Analysis of the output reveals that, in some situations, WAPP output is very sensitive to the inclusion of the altimeter data because of the resulting differences in the subsurface predictions. The change in weapon presets could be so much that the effectiveness of the weapon might be affected. / Lieutenant Commander, United States Navy

Approved for public release; distribution is unlimited. / The Marine Corps has recently embarked on the development of a Vertical Takeoff and Landing Unmanned Aerial Vehicle (VTUAV) to replace the aging Pioneer system. This thesis examines the critical elements this platform must possess in order to effectively support small units operating in urban environments. We address this issue by creating and exploring an agentbased simulation of a platoon conducting an urban patrol in a setting similar to those currently being encountered in Iraq. The platoon utilizes the VTUAV as an intelligence-gathering asset. We use an efficient designed experiment to generate data from the simulation scenario, and then use multiple regression and regression trees to relate the UAV capabilities to the patrol's operational effectiveness. Our results suggest that the effectiveness of a VTUAV is greatly influenced by noise in the urban warfare environment. We use a loss function, along with the regression models, to identify UAV configurations that improve operational effectiveness yet are robust to uncertainties about civilian and insurgent behavior. The VTUAV must have high communication capability, as well as accurate sensing, in order to perform well across a range of environmental conditions. / Captain, United States Marine Corps

The United States is and will continue to be engaged in a form of warfare in which the enemy finds shelter among and gains intelligence from the population. This is not a new form of warfare, but, given the advances in technology and increased globalization of the modern age, it has become an exponentially more lethal form of conflict. This thesis examines current U.S. unconventional warfare doctrine to determine its origins and assess its feasibility in different environments. Drawing upon the military theories of Clausewitz, this paper attempts to lay out a new approach and broaden the spectrum of American unconventional doctrine and irregular response. An examination of the American â hearts and mindsâ approach to unconventional warfare, based largely upon British colonial experience, suggests that current doctrine could be based on a faulty interpretation of history. Newly emerging knowledge points to the need to adopt an unconventional strategy focused more on establishing authority than gaining popularity. This approach, dubbed â authoritative control,â has both a historically successful track record and is fairly easy to implement. For the United States to be successful in future unconventional conflict, an expansion of doctrine must occur immediately.

This thesis examines the potential destabilizing implications of conventional prompt global strike capabilities that operate from or through space. Existing material on this subject is largely limited to debates over the merits of terrestrial verses space basing and arguments against deployment over perceived increases in the likelihood of inadvertent nuclear war. This thesis addresses these issues, but takes the next step and analyzes the root causes and proposes possible solutions to the "security dilemma" these weapons may create. The central finding is that in order to fully exploit the predicted advantages of conventional prompt global strike capabilities, significant changes to the enduring Cold War nuclear postures of the United States and Russia are necessary.

uction efforts. This thesis explores whether a DO is suitable for urban combat operations by analyzing the results of simulations created in Map Aware Non-uniform Automata (MANA). The employment of a DO is compared to employment of a traditional Marine infantry platoon in an urban combat scenario based upon data obtained from Operation al-Fajr, conducted in Fallujah, Iraq, in November 2004. The study also examines the effects caused by varying the terrain to that of Range 200, constructed at the Marine Air Ground Training Command, Twentynine Palms, California. Modeling insights, obtained by surveying Marines with urban combat experience in Iraq, tie into the research effort. This research indicates that the DO is marginally more effective than a Traditional Platoon in urban combat. DO also shows a greater sensitivity to combat outcomes due to urban density, and produced significantly better results in terrain with a lesser density of urban structures.

The purpose of this research is to investigate how to exploit frequency and polarization techniques in reducing the effects of jamming against UAV relay communication links in an urban warfare environment. There have been early studies investigating the diversity techniques against multipath and fading problems in urban environments. A medium without any jamming issues seems almost impossible to exist in today's warfare. Basically, noise jamming issues were taken into consideration. Urbana Wireless Toolset was used as the computer simulation. Even though it is a powerful tool to predict the radio wave propagation in urban environments, due to the problems about modeling the cities (lack of detail, like the shapes of the buildings, objects and vehicles that could be found in the streets, and other details that would contribute to the propagation mechanisms), it can only give us a trend with some guidelines instead of an exact mapping of propagation.

This thesis focuses on developing and analyzing a model for an aerially deployed real-time targeting sensor net to close the current gap that exists between the potential technological-doctrinal capability within society and that of the military. It outlines current real-time targeting need due to the decomposition of warfare after the fall of the Soviet Union, and portrays the targeting discrepancies in the Global War on Terror. From end-user surveys requirements are layed out for a system of systems to meet targeting needs. A feasible solution consisting of a system architecture anchored in existing commercial off the shelf technology is proposed to meet the discrete deliverables necessary to accomplish targeting goals to deal with asymmetric threats in opaque environments. / US Navy (USN) author.

The military threat of hostile submarines is increasing and the need for effective Anti-Submarine Warfare (ASW) operations is also increasing. In response, the ROK government and military have improved their ASW capabilities. In this thesis, the recommended track spacing for an Archimedes spiral search in a datum search problem was studied. To find a recommended track spacing, three analytical approaches were explored. Each of three analytical approaches has its own strengths and weaknesses. This analysis combined three analytical functions into a single parameterized expression. To find the best-fit parameters maximizing probability of detection, a simulation experiment with a NOLH (Nearly Orthogonal Latin Hypercube) design was used. / Korean Army author.
