During the past ten years I have been involved in the development of Naval SAGW as leader of the Seacat, Seaslug and Sea Dart Project Teams within the RAE Weapons Department. The RAE's general responsibility has been that of co-ordinating R&D authority, plus being R&D authority for specific parts of the missile, but the detailed range of responsibility, plus its title, has varied from time to time and project to project.

In addition to the co-operation between the various project teams in Weapons Department we have across-the-board teams developing mathematical modelling techniques and programmes, and my colleagues from industry and the Royal Navy in the audience will note a familiar emphasis on modelling in my lecture.
