 | Currently acoustics is the primary modality for underwater communication even though it presents a difficult channel. To try and cope with the challenges of the channel many MAC protocols and PHY layer techniques have been proposed. In this paper we present a research platform that allows developers to easily implement and compare their protocols in an underwater network and configure them at runtime. We have built our platform using widely ... |

| The Department of Defense and, subsequently, the U.S. Navy have embraced a strategy of exerting influence through information dominance versus amassing a large presence. This philosophy, called Net-centric Warfare, uses sensor and network technology to leverage naval platforms towards realizing effects previously achievable only by a larger force. In adapting this strategy, the U.S. Navy has realized many benefits, but has also increased its reliance on the technologies implementing Net-centric ... |

| In the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic mobile communication for tactical Special Operation Force (SOF) networks, as well as SOF units that are ad hoc networking with first responders conducting emergency/rescue and disaster relief operations. Such network scenarios cannot rely on centralized and organized connectivity, and should instead employ ... |

| No longer does Naval Surface Warfare merely entail battle between symmetric naval fleets conducted in large open water engagements. Today's Surface Warriors must have the training and capability to also fight asymmetric threats in congested locations of strategic value. Operations conducted within straits, choke points, and island cluttered littorals pose considerable risk and numerous challenges for today's Navy. Shore based anti-ship missiles, torpedo and missile carrying small fast patrol boats, ... |

| When groups of platforms, sensors, and weapons are able to communicate with each other in real-time, they form a network. Modern warfare increasingly involves network-centric operations, the military strategy that seeks to translate informational advantages gained through the cooperation of all platforms in the network into increased overall mission effectiveness. For this thesis, the Time-to-Kill is our metric to quantify mission effectiveness because a given time-sensitive target is vulnerable to ... |

| Land platforms are increasingly required to carry out a wide range of roles in support of very diverse operations ranging from high intensity conflict to Operations Other Than War (OOTW). The acceptance of casualties is low and reduction is a strategic political imperative. As a result, crew/platform survivability is important to mission effectiveness and success. Methods for achieving survivability need to be objectively assessed and prioritized to meet cost constraints. ... |

 | On April 6, 2009, Secretary of Defense Robert Gates announced a number of decisions regarding the Department of Defense's (DOD's) proposed FY2010 defense budget. Among these was a decision to defer the procurement of an 11th San Antonio (LPD-17) class amphibious ship (and of another sealift-type ship called the Mobile Landing Platform, or MLP) from FY2010 to FY2011 in order to assess costs and analyze the amount of these capabilities ... |

| Self-Propelled Semi-Submersibles now transport an estimated 75% of cocaine originating from Colombia and headed for the United States. There are several types of search platforms (i.e., units to detect, classify, and interdict) being employed by the Joint Interagency Task Force South to combat the semi-submersibles. We use a defender-attacker optimization model to maximize the defender?s probability of successful detection and classification of the semisubmersible through the advantageous disposition of these ... |

| An investigation has been carried out into the effects of wireframe detail and model subprocessing on the predicted optical frequency (OF) signature of a platform. This report describes the results of that investigation. Overall it is concluded that to be able to compare the computed OF signatures of different platforms with validity, the models of the platforms have to incorporate the same level of wireframe detail, especially in internally-heated regions ... |

| Superstructure sea spray icing and atmospheric icing from snow, freezing rain, freezing drizzle, rime, sleet, and frost reduce the safety of offshore platform and supply boat operations. Though icing reduces safety and reduces operational efficiency, it has not caused the loss of offshore platforms. Supply boats are at greater risk of loss from icing than are platforms.

| Increasingly high aircraft power demands require that the interactions between an aircraft's electrical subsystem and the engine subsystem be considered in dynamic, system-level tests. Traditionally, system-level dynamics have only been captured in completely assembled aircraft systems. Component-level or subsystem-level optimization is no longer appropriate because highly interdependent dynamics between subsystems only become apparent during system-level analysis. In an effort to mitigate program risk, enable system-level optimization, and reduce the high ... |

| Gain and bandwidth metrics of broad-band low-profile antennas severely deteriorate when they are placed conformally onto the conductive skins of air, sea, and ground platforms. This detrimental effect is primarily due to out-of-phase reflections from the conductive body interfering with the antenna's self radiation. Furthermore, lateral waves launched by the antenna couple into the thin substrate placed between the antenna and the platform, giving rise to surface waves resulting in ... |

One concept that has been around since the 50s but yet to be utilized on a launch platform is the aerospike, or plug nozzle.

| Ship performance characteristics, such as max-sustained speed, acceleration, and maneuverability are generally pre-determined as a platform requirement based on precedents. However, these pre-determined performance characteristics have far reaching impacts on the size, logistics, manning, and cost of the ship platform. Instead of designing to pre-defined platform performance requirements, ship performance characteristics should be determined based on fulfilling mission objectives. This research evaluates the viability to effectively determine if the ship ... |
