CAP Scientific

CAP Scientific Ltd was a British defence software and systems company established in 1979 by four former employees of Scicon, a BP subsidiary. The founders wanted to create a specialist enterprise focused on software and computer systems for United Kingdom defence applications, and secured backing from CAP-CPP, a commercial software house. The company subsequently became part of the wider CAP Group and operated in a period when military computing was dominated by large contractors supplying bespoke hardware and proprietary systems. The company's early development centred on research and engineering work for the Royal Navy and the United Kingdom Ministry of Defence. Its naval activities included support for the Admiralty Research Establishment, maritime technology programmes, machinery-control systems, surveillance systems, and command systems for surface ships and submarines. CAP Scientific also developed land and air defence capabilities, including work as prime contractor for the British Army's Brigade and Battlegroup Trainer. Outside defence, it created a Scientific Systems business covering areas such as energy generation and conservation. In 1985 it established the Centre for Operational Research and Defence Analysis, or CORDA, as an independent analytical unit providing assistance with investment appraisal and defence analysis. A major turning point came during the Falklands War in 1982. The Royal Navy required additional computational capacity for improved fire-control solutions for the submarine-launched Harpoon system. CAP Scientific rapidly integrated an experimental Digital Equipment Corporation PDP-8 installation into a Royal Navy submarine before its deployment to the South Atlantic. This was an early example of adapting commercially available computing equipment for an urgent military requirement. The work led to the development of a standard submarine fit known as DCG, which provided additional processing capacity for submarine command systems and demonstrated CAP Scientific's ability to respond quickly to operational needs. The company built on this reputation when the Ministry of Defence opened a competition for the command system of the planned Vanguard-class submarines, which would carry the Trident missile system. In 1983 CAP Scientific joined Gresham-Lion, a British supplier of torpedo-launch control equipment, to create Gresham-CAP Ltd. The consortium won the competition with the Submarine Command System, or SMCS. Rather than relying on traditional purpose-built electronics, the system used distributed processing, commercial off-the-shelf components, modular software, and substantial use of the Ada programming language. Its architecture used Intel 80386 processors and MultiBus technology; earlier use of INMOS Transputer processors for sonar tracking was later phased out as more general-purpose processors became suitable for the task. The SMCS award was strategically important because it displaced Ferranti, which had supplied command systems for Royal Navy ships and submarines for many years. It was regarded as an important example of open competition in British defence procurement and helped establish CAP Scientific as a credible naval systems supplier. The founders later sold their entire shareholding to CAP-CPP. CAP-CPP subsequently became CAP Group plc, and CAP Group acquired YARD Ltd in June 1986. YARD was a marine engineering consultancy formerly associated with Yarrow Shipbuilders. CAP Scientific and its related businesses then became involved in the development of a surface-ship command system for the Royal Navy's Type 23 frigates. Working with Gresham-CAP and Racal Electronics, the business adapted the SMCS architecture into a distributed system generally referred to as the Surface-Ship Command System, or SSCS. CAP Group merged with the French company Sema-Metra SA in 1988 to form Sema Group plc. The defence activities were subsequently associated with Sema Scientific. The Type 23 programme…

CAP Scientific was founded in 1979 by four colleagues from Scicon, a BP subsidiary. They sought to establish a specialist United Kingdom company supplying software and computer systems for defence applications and obtained financial and organisational backing from CAP-CPP. The company entered a defence market in which large prime contractors generally delivered purpose-built military computers, but CAP Scientific pursued partnerships and newer distributed-computing approaches. By the mid-1980s the business had developed several divisions. Its Maritime Technology operation supported the Admiralty Research Establishment and worked with Vosper Thornycroft Controls on machinery-control and surveillance systems for Royal Navy ships and submarines. Its Naval Command Systems operation provided action-information-organisation expertise for surface and submarine fleets. A Land Air Systems business undertook research and development and acted as prime contractor for the British Army's Brigade and Battlegroup Trainer. The company also created a Scientific Systems operation for non-defence work in energy generation and conservation, and established CORDA in 1985 as an independent centre for operational research and defence analysis. The Falklands War produced the company's first major breakthrough. In 1982 the Royal Navy needed greater computing capacity for urgent fire-control work involving the RN-Harpoon missile. CAP Scientific's engineers rapidly fitted an experimental Digital Equipment Corporation PDP-8 system to a submarine before it sailed for the South Atlantic. This deployment helped establish DCG, a standard additional-processing fit for Royal Navy submarines, and demonstrated the military value of commercial computing equipment adapted for operational use. In 1983, the Ministry of Defence opened a competition for the command system of the Vanguard-class submarines. CAP Scientific partnered with Gresham-Lion in Gresham-CAP Ltd and won the contract with the Submarine Command System. SMCS used distributed processing, commercial off-the-shelf components, modular software, and Ada. Its architecture included Intel 80386 processors and MultiBus. INMOS Transputers were also used for sonar tracking, although they were later replaced as general-purpose processors became more capable and easier to support. The competition win displaced Ferranti, a long-established supplier of Royal Navy command systems. The company later participated in the competition for the command system of the Type 23 frigates. With Gresham-CAP and Racal Electronics, it developed a surface-ship derivative of the SMCS architecture, known as SSCS. The large fixed-price programme overran and contributed to financial and organisational difficulties affecting the participating businesses. During this period CAP Group merged with Sema-Metra SA in 1988 to become Sema Group plc, and the defence operation was associated with Sema Scientific. In 1991 Sema Group placed most of its defence activities, including the businesses descended from CAP Scientific and YARD Ltd, into the BAeSEMA joint venture with British Aerospace. British Aerospace bought out Sema's interest in 1998. The subsequent 1999 merger of British Aerospace and Marconi Electronic Systems created BAE Systems, under which parts of the former CAP Scientific operation continued, including activities later associated with BAE Systems Insyte. CAP Scientific consequently survives as a corporate and technological predecessor rather than as an independent active brand.

A specialist British defence software and systems company focused on applying distributed computing, commercial off-the-shelf hardware, and modular software to naval command, control, surveillance, and military training requirements.

• DCGSubmarine computing fit1982

  DCG was a standard additional-processing installation developed after CAP Scientific's urgent Falklands-era deployment of an experimental PDP-8 system in a Royal Navy submarine. It provided extra computational capacity for submarine command systems and represented an early operational use of commercial off-the-shelf computing equipment in a military setting.

• Submarine Command System (SMCS)Naval command-and-control system1983

  SMCS was the distributed command-system architecture proposed by Gresham-CAP for the Royal Navy's Vanguard-class submarines. It used commercial processors and bus technology together with modular software, much of it written in Ada. The system became the foundation for later naval command-system developments and helped CAP Scientific displace Ferranti in a significant British defence procurement competition.

• Surface-Ship Command System (SSCS)Surface-ship command system

  SSCS was a surface-ship adaptation of the SMCS distributed-processing architecture developed for the Royal Navy's Type 23 frigate programme. CAP's consortium worked with Gresham-CAP and Racal Electronics on the system. The programme involved a large fixed-price contract that overran and contributed to later corporate restructuring around the defence business.

• Brigade and Battlegroup Trainer (BBGT)Military training system

  BBGT was a British Army training and simulation programme for which CAP Scientific's Land Air Systems business served as prime contractor.
