BAE Systems has secured a systems engineering and integration support services contract to continue working with the US Navy Strategic Systems Programs (SSP) office.
The five-year contract is worth up to $478m.
The SSP is responsible for maintaining the Strategic Weapons System and Attack Weapons System on-board current US Ohio and UK Vanguard class submarines.
The office will also be in charge of overseeing the weapon systems on future US Columbia and UK Dreadnought class submarines.
BAE Systems Integrated Defense Solutions vice-president and general manager Lisa Hand said: “We are proud to continue providing full system-level lifecycle capabilities to SSP that will help advance their digital engineering strategy to ensure the readiness of the navy’s strategic missions.
“BAE Systems brings extensive systems integration expertise to a wide range of defense initiatives that support two-legs of the nation’s nuclear triad.”
The company stated that it uses model-based and digital engineering approaches to help in optimising the performance and operating costs of highly complex weapon systems.
The applications support system requirements, design, analysis, verification and validation activities throughout the lifecycle of the systems.
Headquartered in the UK, BAE Systems offers defence technology services across the air, maritime, land and cyber domains.
It employs around 89,600 people in more than 40 countries.
The company recently tested advanced precision kill weapon system (APKWS) laser-guided rockets at Yuma Proving Grounds in the US.
The test demonstrated the counter-strike capabilities of the rockets against Class 2 uncrewed aerial systems (UAS).
