Through the creation of a large number of concept designs, the cost and vessel impact of deploying and supporting amphibious operations has been investigated. The investigation has looked at capabilities such as the transportation and delivery of vehicles, landing craft, aviation and embarked troops in a number of platform types such as LPDs, LHDs and Ro-Ros. A series of trends describing the costs of the capability have been investigated to estimate the cost of individual capabilities within a design. Over the timeframe of the study, vessel manning is predicted to change and a method of predicting the crew requirement has been developed to investigate the impact of reduced manning on amphibious platform designs. This is the first of two stages of work; in the second stage the requirements for a task group will be investigated to determine the best way to deploy capability at a fleet level.
