Lockheed Martin continues TMRR work on Mk21A RV
Prototype flight test plan to be altered
Lockheed Martin has obtained a $34.94 million contract modification from the USAF Nuclear War Center, for continued technology maturation and risk reduction (TMRR) R&D work on the Mk21A Reentry Vehicle (RV).
Under a $108 million contract awarded in October 2019, Lockheed Martin is already working closely with the USAF and the National Nuclear Security Administration on TMRR to modify existing Mk21 RVs. The aim is to add the capability to deliver the W87-1 warhead (pictured) for the Ground Based Strategic Deterrent system.
To further mature the technology, Lockheed Martin will now modify the TMRR prototype flight test plan to include preparations for a second flight test and development of two prototype RVs with telemetry capability.
Work is expected to be completed by 21 October 2022.
