The US Navy has selected Huntington Ingalls Industries to install hypersonic missiles on the Zumwalt class destroyers USS Zumwalt and USS Michael Monsoor. The retrofit process will involve the removal of both 155mm Advanced Gun System mounts and associated below deck infrastructure to accommodate launch tubes for the Vertical Launch System for the Common Hypersonic Glide Body (C-HGB) developed for the Army, Air Force and Navy.
