US submarines to get torpedo tube-based autonomous vehicles

The U.S. Navy is set to enhance its submarine capabilities through a new contract awarded to L3Harris Technologies by the Department of War’s Defense Innovation Unit. The contract involves delivering the Torpedo Tube Launch and Recovery (TTLR) system, which enables submarines to deploy and retrieve Iver4 900 autonomous underwater vehicles (AUVs) via torpedo tubes. This system allows submarines to conduct intelligence, surveillance, reconnaissance, mine detection, and seabed warfare missions without surfacing or endangering personnel, thereby increasing operational stealth and flexibility. A key feature of the TTLR system is its modular design, allowing integration into existing submarine classes without the need for new vessel construction, making it a cost-effective upgrade. The system incorporates advanced lithium-ion battery technology approved for both submarine and aviation use, enabling longer mission durations and hot-swappable power units for continuous operations. This innovation supports the Navy’s manned-unmanned teaming strategy and enhances interoperability with allied naval forces, including collaborations
