Background
The REMUS 600 is a heavyweight torpedo-tube-compatible uncrewed underwater vehicle (UUV) made by HII's Mission Technologies division, part of the REMUS family that has been deployed by more than 30 navies worldwide. In May 2026 a REMUS 600 was launched from and recovered through the torpedo tube of the US Navy submarine USS Delaware, the integration milestone that turns a submerged attack submarine into a forward-deployed sensor and mine-hunting host without surfacing.
HII has delivered more than 750 REMUS vehicles across its family of sizes. The REMUS 600 is designed for mine countermeasures, intelligence-gathering, and hydrographic survey, operating at medium depths for extended missions. Its torpedo-tube launch and recovery removes the need for a surface support vessel, giving submarines a clandestine underwater reach that surface-ship-launched UUVs cannot match.
The Royal Navy connection comes through HII's ARMOR Force initiative with Babcock, which is positioned around REMUS capabilities for Royal Navy submarines. For European navies protecting seabed cables and pipelines, torpedo-tube-launched UUVs maturing at this pace in the US fleet represent both a procurement reference and a timeline signal: the capability is moving from demonstration to operational delivery.
