REMUS 600
HII (Huntington Ingalls Industries) 600-series Remote Environmental Monitoring Unit System; a torpedo-tube-launched autonomous underwater vehicle used for mine countermeasures and ISR.
A REMUS 600 was launched from and recovered through the torpedo tube of the US submarine USS Delaware in May 2026, the milestone HII showcased weeks later at Farnborough's Combined Naval Event to pitch submarine-launched underwater drones to the Royal Navy.

The REMUS 600 is a heavyweight, torpedo-tube-compatible uncrewed underwater vehicle built by HII's Mission Technologies division, part of the wider REMUS family that has been delivered to more than 30 navies worldwide . It operates at medium depths for extended missions, doing mine countermeasures, intelligence-gathering and hydrographic survey work that would otherwise need a crewed vessel or a support ship overhead.
Its defining feature is that it needs no surface support vessel: launched and recovered through a submarine's torpedo tube, it gives an attack submarine a clandestine underwater reach that surface-ship-launched drones cannot match, at the cost of the size and payload constraints a torpedo tube imposes.
The Royal Navy route for REMUS 600 runs through HII's ARMOR Force initiative with Babcock, which positions the vehicle's capabilities for eventual submarine integration rather than a stand-alone export sale.
REMUS 600 fires from a submarine
In May 2026 a REMUS 600 was launched from and recovered through a torpedo tube aboard USS Delaware, the integration milestone that turns a submerged attack submarine into a forward-deployed mine-hunting and sensor host without it ever surfacing . HII showcased the demonstration weeks later at the Combined Naval Event in Farnborough, pitching the capability to the Royal Navy alongside its Babcock partnership.
For REMUS 600 specifically, the demonstration is the clearest evidence yet that torpedo-tube launch and recovery, long a design goal for the wider REMUS family, now works in practice rather than on a test rig, at a moment when European navies are under pressure to prove submarine-launched seabed capability against a maturing US-led effort.
