US Navy to Deploy Uncrewed Underwater Vehicles from Submarines by End of 2024

The US Navy (USN) is set to deploy a torpedo-tube launch-and-recovery (TTL&R) uncrewed underwater vehicle (UUV) capability on an operational submarine for the first time. This deployment will begin by the end of 2024 in the European theatre. Although submarines have previously used UUVs, the TTL&R method simplifies deployment and retrieval, enhancing capabilities and maneuverability in the underwater domain.

Vice Admiral Rob Gaucher, Commander of Submarine Forces, announced at the Naval Leaders' Combined Naval Event 2024 (CNE 24) in Farnborough, UK, that the UUVs would be installed on the USS Delaware in the coming weeks and will be deployed by year's end. The Delaware, a Virginia-class nuclear-powered attack submarine commissioned in April 2020, is part of the USN's plan to develop a fully integrated SSN-based UUV capability.

Vice Adm Gaucher emphasized the importance of increasing UUV operations within the submarine force and outlined plans to accelerate this development in 2024. The deployment will include an HII REMUS 600 UUV, tested successfully in late 2023 when launched and recovered via the Delaware’s torpedo tube. The US Navy’s regional commanders in Europe will seek exercises and opportunities to test this TTL&R-based UUV capability during the Delaware’s deployment across the Atlantic.

The second successful test of the TTL&R capability occurred on the Delaware in December 2023, following an earlier test in the Pacific. Vice Adm Gaucher highlighted the need to integrate emerging commercial UUV technologies into regular naval operations, stressing the importance of practical experience and trials.

The TTL&R capability, part of the AUKUS (Australia/UK/US) strategic partnership, exemplifies new concepts and technologies being developed under Pillar 2. This development underscores the collaboration between the three navies in advancing subsea and seabed warfare capabilities, with UUVs playing a crucial role in defending underwater infrastructure.

Vice Adm Gaucher concluded by emphasizing the need for more exercises and development to expand uncrewed operations, aiming for exponential growth in the use of uncrewed systems.
