L3Harris Technologies has been awarded a contract modification to provide services and support for flight test instrumentation systems for the Trident II Strategic Weapon System, with work including activity at the Barrow-in-Furness facility in the United Kingdom.
The modification, awarded to L3Harris subsidiary Interstate Electronics Corporation in Anaheim, California, covers “new procurement options under a previously awarded and announced contract” and is structured as a cost-plus-fixed-fee and cost-plus-incentive-fee arrangement. Work is expected to be completed by February 2029.
The bulk of the work will be performed in the United States, with Yorba Linda, California accounting for 55 per cent of the programme, Cape Canaveral, Florida 30 per cent, and Washington DC seven per cent. The remaining work is split between Barrow-in-Furness in the United Kingdom at three per cent, Bremerton, Washington at two per cent, Kings Bay, Georgia at two per cent, and Groton, Connecticut at one per cent.
The Barrow-in-Furness element reflects the UK’s role in the Trident II programme, with the town home to BAE Systems’ submarine construction facility where the Royal Navy’s Vanguard-class ballistic missile submarines, which carry the Trident II D5 missile, are maintained and where the successor Dreadnought-class boats are being built.
Funding obligated at time of award totals $59.6 million, drawn from fiscal 2026 operations and maintenance, research, development, test and evaluation, other procurement and weapons procurement funds. The notice confirms the contract action “also benefits a Foreign Military Sale”, a reference to the UK’s participation in the shared Trident programme, and was awarded “on a sole source basis” given the specialised nature of the work.
