The Air Force has given Lockheed Martin a $996 million contract to produce a reentry vehicle (RV) for its new Sentinel intercontinental ballistic missile by Oct. 20, 2039.

Under this sole-source acquisition deal, announced Oct. 30, Lockheed will engineer, manufacture, and design the new RV, dubbed MK21A, in several locations including King of Prussia, Penn.

The contract, overseen by the Air Force Nuclear Weapons Center, aims to reduce technical risks and ensure the affordability of the RV, according to the Pentagon’s release.

The specialized RV will carry the W87-1 warhead, which entered a new phase this year in its Modification Program involving tests and analysis to validate the chosen design.

National laboratories are developing and producing test hardware for the warhead, expected to deploy in the early 2030s with the Sentinel ICBM.
