The Littoral Combat Ship, or the Designs of Liquid Sovereignty

Experiments were conducted at the U.S. Naval Academy's Hydromechanics Laboratory to determine the effect of finite water depth on the resistance, heave, and trim of two different trimaran models. The models were tested at the same length to water depth ratios over a range of Froude numbers in the displacement speed regime. The models were also towed in deep water for comparison. Additionally, the side hulls were adjusted to two different longitudinal positions to investigate possible differences resulting from position. Near critical speed, a large increase in resistance and sinkage was observed, consistent with observations of conventional displacement hulls. The data from the two models are scaled up to a notional 125-m length to illustrate the effects that would be observed for actual ships similar in size to the U.S. Navy's Independence Class Littoral Combat Ship. Faired plots are developed to allow for rapid estimation of shallow water effect on trimaran resistance and under keel clearance. An example is provided.

Littoral Combat Ship

In 2014, the Small Surface Combatant Task Force completed an innovative study on alternate proposals to procure a capable and lethal small surface combatant. Modified Littoral Combat Ship (LCS) concepts, new design concepts, and existing design concepts were examined. This paper describes the set-based design approach employed to conduct this study.

Littoral Combat Ship

Recent experience with the Littoral Combat Ship (LCS), Focused Mission Ship, Ship Structure Committee (SSC) Project SR 1437 and other programs for the US Navy has required the development of structural designs for the unique loads that occur on high speed craft. Using the ABS Rules for Building and Classing High Speed Naval Craft (ABS HSNC) and the DNV Rules for Classification of High Speed, Light Craft and Naval Surface Craft, (DNV HSLC&NSC) the hull girder, slamming and vehicle deck loads required for the design of a US Navy High Speed craft/combatant are reviewed herein. Materials and allowable stresses associated with each of the class society’s rules are summarized along with the required loads and resulting structural modifications for SSC Project SR 1437, which used each of the two rule sets to determine the structural modifications for converting a commercial, high speed ferry into a high speed military transport capable of unrestricted (i.e., open ocean) operation.

The U.S. Navy's at-sea replenishment system is a mobile supply line designed to support the deployed carrier task force (CTF)/cruiser/destroyer (CRUDES) surface action group (SAG) and forward deployed units while at sea. In the Pacific, the main component of the mobile supply line, the combat logistics force (CLF) ship, has become a possible target with the development of the anti-ship ballistic missile. With the ability to target and disable a CLF, an enemy can now disable a deployed CTF/CRUDES fleet by eliminating its required resources. With the goal of preserving the CLF's capabilities to perform its mission while avoiding ASBM threat, the authors consider the possibility of utilizing a “mini-CLF” to shuttle fuel between CLFs operating in a safe environment and warships operating in a threat zone. The authors perform two analyses: they (1) analyze the feasibility of using the Littoral combat ship/joint high-speed vessel, reconfigured as a shuttle to transport resources, and (2) analyze requirements for development of a new class of ships to support the CTF/CRUDES SAG while deployed in the Pacific.
