General Dynamics Receives $65M Contract in Support of Royal Navy Dreadnought Class SSBN, HMS Valiant

General Dynamics Mission Systems (GDMI) has been awarded a contract, worth around $65 million, in support of the UK Royal Navy’s second Dreadnought Class ballistic missile submarine (SSBN), the future HMS Valiant.

The cost-plus-incentive-fee contract is for the Strategic Weapon System Fire Control Subsystem hardware, associated deliverables, and spares for production efforts supporting HMS Valiant, and the U.K. Software Facility.

The contract was awarded by U.S. Navy’s Strategic Systems Programs (SSP) which directs the development, production, logistic support, and sustaining engineering effort of the Navy’s Strategic Weapons Systems. The SSBNs of both the Royal Navy and the U.S. Navy are armed with the same submarine-launched ballistic missile (SLBM), the UGM-133A Trident II/ Trident D5.

The contract work will be performed in Pittsfield, Massachusetts, and is expected to be completed Aug. 22, 2025.

It was announced later last year, by the then UK Defence Secretary Gavin Williamson, that the second Dreadnought class SSBN will be named HMS Valiant.

The Dreadnought class is the future replacement for the four Vanguard class ballistic missile submarines currently operated by the Royal Navy. Like their predecessors, the new submarines will also carry UGM-133A Trident II (D5) submarine launched ballistic missiles (SLBM).

Once built, the submarines will measure 153.6m long, with a displacement of 17,200 tonnes. They are being delivered by the newly-formed Dreadnought Alliance, a joint management team established between the UK Ministry of Defence (MOD), BAE Systems and Rolls-Royce.

Provisionally named “Successor” (being the successor to the Vanguard class SSBNs), it was officially announced in 2016 that the first of class would be named HMS Dreadnought, and that the class would be the Dreadnought class. The next three boats will be called HMS Valiant, HMS Warspite and HMS King George VI.

Construction on HMS Dreadnought started in October 2016 at the Barrow-in-Furness shipyard operated by BAE Systems Maritime – Submarines. The submarine is expected to enter service in the late 2020s or early 2030s.
