The question that this report seeks to address is what is the best approach to acquiring a large number of warships in an emergency? Two approaches were tried by the U.S. Navy during World War One and Two. The first approach was to use an existing fleet destroyer design and attempt to accelerate production by increasing the number on order and the number of building yards. The second approach was to develop simpler and less capable emergency escort designs which lent themselves to quick...

This thesis addresses the problem of routing a navy Carrier Strike Group (CSG), or other groups of ships, through a maritime chokepoint that presents one or more shore-based missile threats. The goal is to identify a path that minimizes risk to the CSG's HVU (High Value Unit, i.e., the CSG's aircraft carrier). The HVU's escort ships are assigned optimal positions relative to the HVU during the transit to maximize the overall probability of avoiding and/or defeating attacks. The problem is...

The thesis explores the phenomena unique to echo-ranging with a source widely separated from the receiver. In an asset-austere era of antisubmarine warfare, this technique serves as a tactical advantage, particularly in the passive tracking of a submarine. Particular emphasis is placed on the terms of the sonar equation most affected by the bistatic geometry: Reverberation level and target strength. The research is particularly applicable to ongoing NATO and Naval Laboratory work involving the...

Japan has significant capabilities to protect its sealanes out to 1000 nautical miles to the south of its main ports. By concentrating military expenditures on forces to improve air defense, strait control, and convoy operations, Japan could have a credible defense, even in the worst possibility: global war and a Soviet attack. The Japanese should concentrate on improving the air defense of Japan and the ocean between Iwo Jima and Okinawa, increasing their stockpile of mines and their mine...

The summer of 1991 marked the first time in recent history that Russia offered to escort ships of other countries across the Northern Sea Route (NSR). For moving cargo between the North Pacific region and Northern European ports, the NSR, along Russia's northern coastline, is between 35 and 60% shorter than the traditionally used routes through the Suez and Panama Canals. In addition to its shorter distance, there already exists an extensive ports and shipping infrastructure, a current cargo...

This thesis is the application of the concept of design-to-cost to the project of the FFG frigates. Using the available data relative to the major escort programs since 1950, a curve of force effectiveness vs. number of ships, similar to that presented by Vice Admiral Price in his congressional testimony on design of the patrol-frigate or FFG-7, was constructed and the results discussed.

The finite element program VAST, and experimental vibration data are used to analyze a serious vibration problem with the new mast on the Mackenzie class ship, DDE 261, HMCS AU'APPELLE. It has been determined that the mast's natural frequency of vibration falls into the range of excitation frequencies produced by the propeller shaft rotation. It is postulated that the propeller excitation is driving both resonant hull and mast modes together. After analysis of some possible solutions using...

What is the fully burdened cost of supply to combatant ships in remote locations? Currently, there are directives that require an estimate of the fully burdened cost of energy in a number of analyses in acquisition, but the approved method(s) for estimating this cost are still being developed. Several analyses fail to account for the indirect costs associated with supplying logistics assets. Therefore, we propose a method for estimating the fully burdened cost of supply in a self-sustaining...

The Navy needs to revolutionize the way it designs and builds the next generation of warships. With the amphibious fleet next in line for modernization, the Navy should give this group of ships improved warfighting capabilities. Currently, Naval amphibious ships rely on escorts from Carrier Battle Groups to protect them on the high seas in route to the Amphibious Objective Area and during the amphibious assault. These ships have no land attack, anti-air warfare, or anti-surface warfare...

Screening methods are beneficial for studies involving simulations that have a large number of variables where a relatively small (but unknown) subset is important. In this paper, we show how a newly proposed Lasso-optimal screening design and analysis method can be useful for efficiently conducting simulation screening experiments. Our approach uses new criteria for generating supersaturated designs, and a new algorithm for selecting the optimal tuning parameters for Lasso model selection. We...

High-speed displacement vessels are widely used in most of the smaller navies because they provide low operating cost, combined with performance adequate for policiing 200 nm Exclusive Economic Zones. Feasibility designs of this kind of vessel, such as corvettes and patrol boats, always require calm water resistance estimates. This paper attempts to use available data to analyze main hull form parameters that effect the resistance characteristics of the vessel. A few high speed round bilge...

Ship defense in convoy operations against Anti-Surface Missiles (ASM) has been an important aspect of Naval Warfare for the last two decades. Countries in a state of conflict often conduct threatening operations in their own territories in order to slow or stop the enemy merchant ship traffic through the straits or littoral waters. Such littoral scenarios, the quantity and capability of ASM's in non-NATO countries pose a significant threat to the safe operation of the NATO forces in the waters...
