associated operational analysis. It can be appreciated that to enter into this last concept stage with inadequate exploration of


performance issues, just


emphasises the inherently “political” nature of naval ship acquisition at the front end of the process and why it is often protracted and


seen to be unsuccessful


the solution space or of the style and is unwise as any submission to


proceed is likely to be vulnerable to probing, by approval authorities, on the impact of such issues. This


and


apparently costly, in comparison with the process for even the most sophisticated merchant vessel. However it


is still nothing like as expensive as the development processes for major aircraft programmes, given these include the production of several full scale prototypes. Rather than such extensive preproduction development, there are issues in the case of major naval programmes that are seen to need exploring which are more related to the environment in which design and acquisition are undertaken. This is a complex world well addressed in US Navy organisational papers (such as Tibbitts and Keane [19]) and, for the UK, in Reference 17 and its lengthy published discussion.
