In that year, CAP Scientific established the Centre for Operational Research and Defence Analysis (CORDA) as an independent unit to provide impartial assistance for investment appraisal.
In 1983, CAP Scientific teamed with Gresham-Lion, a British manufacturer of torpedo launch control equipment and now part of Ultra Electronics plc, to form a special purpose company, Gresham-CAP Ltd, to bid for the system.
Gresham-CAP offered a novel distributed processing system based on commercial off-the-shelf components and utilising a modular software architecture largely written in the Ada programming language.
The choice of Intel 80386 processors and MultiBus, when many competing chips were available and the PC had only recently reached the market, showed foresight as the basic architecture remains in service today on RN submarines.
(The choice of an array of INMOS Transputer chips to process sonar tracking data was less successful - whilst they did the job, the lack of long term support / future product line meant they have been phased out once general purpose processors were able to fulfill the role.)
The Falklands War prompted a further competition in British naval equipment supply when an analysis of the loss of HMS Sheffield showed that improvements were necessary in surface ship combat systems.
A contract for the command system for the navy's new Type 23 frigates was cancelled and put out to competition, and after a long campaign was awarded to the CAP and Gresham consortium, teamed with Racal Electronics.
Sema Group invited British Aerospace in as a co-investor in the business, and the activities which once formed CAP Scientific, Gresham-CAP and YARD, together with some BAe interests were merged in 1991 into a new entity, BAeSEMA.
