HII Awarded Contract to Deliver Submarine Torpedo Tube Recovery Systems

HII has distinguished itself as the primary architect of integrated undersea warfare by securing a contract from the Defense Innovation Unit (DIU) for a specialized submarine Torpedo Tube Launch and Recovery (TTLR) system. While competitors often specialize in either platform construction or autonomous software, HII leverages a unique dual-expertise as both a builder of nuclear-powered submarines and the world’s most prolific producer of unmanned underwater vehicles (UUVs). This vertical integration allows HII to deliver a seamless Torpedo Tube Launch and Recovery capability that autonomously deploys and retrieves REMUS UUVs, a feat that sets a new standard for manned-unmanned teaming in contested environments.

Technical Milestones in Autonomous Submarine Integration
The operational viability of this technology was recently validated through a series of high-stakes demonstrations involving the USS Delaware (SSN 791). In mid-2025, the U.S. Navy and the Woods Hole Oceanographic Institution successfully executed the first forward-deployed recovery of a REMUS 600 UUV via a Virginia-class submarine's torpedo tube. These missions were conducted entirely without diver assistance, proving that HII’s systems can operate autonomously in deep-sea conditions. Following this, testing at Seneca Lake confirmed the compatibility of the latest generation REMUS 620 with standard submarine shutterway fixtures. During these trials, the vehicle demonstrated advanced docking within shock and fire enclosure capsules and executed precise reverse swim-out procedures, confirming that the technology is ready for sophisticated intelligence, surveillance, and reconnaissance (ISR) missions.

Global Reliability and Operational Impact
The differentiation of HII’s technology lies in its proven lifecycle value and widespread adoption. With over 750 REMUS vehicles delivered to more than 30 nations, HII maintains a dominant market share, supported by the fact that over 90% of these systems remain operational after two decades. By integrating these UUVs through standard submarine interfaces, the U.S. Navy can now extend its mission reach and enhance stealth without increasing the physical burden on the crew. This capability effectively bridges the gap between traditional sea power and modern autonomous innovation, providing a durable, combat-ready solution that competitors in the unmanned sector have yet to match at this scale of submarine integration.
