According to the Department of War’s announcement, the agreement also supports a Foreign Military Sale.
Work is scheduled to take place in Washington, D.C., accounting for 68% of the effort, with 16% each carried out in Kings Bay, Georgia, and Bangor, Washington.
The contract is expected to be completed by 30 September 2031.
Funding includes an initial allocation of $18.4m from fiscal year 2025 under the One Big Beautiful Bill Act, with no funds set to expire at the end of the current fiscal year.
Deployed on Ohio-class submarines operated by the US Navy and Vanguard-class submarines in the UK, the Trident II D5 system is central to the countries’ at-sea nuclear deterrents.
The missile itself is a three-stage, solid-fuel design, capable of delivering multiple re-entry vehicles over intercontinental ranges.
To address issues of ageing and obsolescence, life-extended versions of the D5 missile (D5LE) have been introduced and are set to remain in service on the current and future replacement classes of ballistic missile submarines.
Separately, BAE Systems has received a $99.2m hybrid contract to provide systems engineering and integration support for the Portfolio Acquisition Executive (PAE) Strategic Systems Programs (SSP).
The contract covers a range of services including engineering, integration, technical data, fleet support, programme management, cybersecurity, and documentation.
The work, which will also support a Foreign Military Sale, is set to take place primarily in Rockville, Maryland, with additional activity in Washington, Cape Canaveral, Saint Mary’s, Silverdale, Groton, Frederick, North Kingstown, York, Huntsville, and Barrow-in-Furness in the UK, along with various other minor locations.
Completion is expected by 30 September 2027.
