The US tested a new warhead for the Sentinel nuclear intercontinental missile

The Mk21A warhead is being developed by Lockheed Martin as part of the Sentinel program, the implementation of which is experiencing difficulties.

The US Air Force in cooperation with the Lockheed company Martin on June 8 announced the first successful test of the Mk21A warhead intended for the Sentinel intercontinental ballistic missile (ICBM). The tests took place on June 17 in California — the warhead was successfully launched by a Minotaur I rocket and flew over the Pacific Ocean. This was reported by the Air and Space Forces Magazine online edition on June 18.

The details of the test are not disclosed, but it is known that the Mk21A warhead is being developed by Lockheed Martin under a contract signed last year. According to the data, the company plans to complete development by October 2039, creating a relatively cheap modification based on the previous Mk.21 warhead from the Minuteman III ICBM.

The Sentinel ICBM is planned to be universal and possibly be placed on mobile platforms. Despite the challenges encountered in the development of Sentinel, including shifting timelines, the US Air Force continues to ramp up efforts to modernize the nation's nuclear arsenal.

“The Mk21 is critical to combating a rapidly changing global threat landscape. Their further development and deployment will ensure a reliable and effective deterrence system for the foreseeable future,” — representatives of Lockheed Martin emphasized.

The authors of the material note that the main goal of the Sentinel program — to replace the outdated Minuteman III ICBMs with new, more modern systems, which will make it possible to ensure the strategic security and effectiveness of the US national defense until 2030.
