HII has been awarded a contract by the Defense Innovation Unit (DIU) to deliver a submarine Torpedo Tube Launch and Recovery (TTLR) system. The system is designed to autonomously deploy and recover HII?s REMUS unmanned underwater vehicle (UUV) from U.S. Navy submarines. The DIU contract builds on HII?s 120-year leadership in undersea warfare as one of two builders of U.S. nuclear-powered submarines, as well as the world?s largest producer of UUVs, and on a series of recent milestone achievements in manned?unmanned teaming.

HII is advancing fully integrated, autonomous maritime capabilities that expand the reach and enhance the effectiveness of the U.S. Navy and its allies. These advancements reinforce HII?s role as a leading sea power company and a key innovator in manned-unmanned teaming across two core growth areas: nuclear-powered submarine design and construction, and autonomous unmanned systems. Integrating UUVs through standard submarine interfaces extends mission reach, enhances stealth, and reduces operational risk and crew burden.
