SINGAPORE --- A Lockheed Martin program has become the first casualty in the U.S. Defense Department’s race to deploy a diverse portfolio of hypersonic missiles as soon as possible.
The Hypersonic Conventional Strike Weapon (HCSW) program will be concluded after the delayed completion of a critical design review in spring 2020. The milestone event was originally scheduled for the third quarter of 2019.
As the DOD rolled out the fiscal 2021 budget request, the U.S. Air Force issued a termination for convenience notice to Lockheed’s Space division on Feb. 10.
Designed to be launched from a B-52, the Aerojet Rocketdyne-boosted HCSW was the first of five hypersonic missile prototype projects that have entered development since 2018. It features a “front end” derived from the Common Hypersonic Glide Body, which is the basis for boost-glide vehicles in development for the Army’s Long-Range Hypersonic Weapon and the Navy’s Intermediate Range Conventional Prompt Strike programs.
