About REMUS 300

REMUS 300 is a small-class autonomous underwater vehicle built on HII's REMUS technology platform. Its modular energy and payload sections support field reconfiguration, wet or dry payload integration and battery exchange through blind-mated end caps. The vehicle is rated to 305 metres, reaches 5 knots and supports mission durations up to 30 hours depending on its energy configuration.

Operators program missions for autonomous execution using HII's Odyssey management suite, with navigation supported by inertial, GPS, long-baseline and Doppler-velocity inputs. Applications include mine countermeasures, search and recovery, environmental assessment, archaeology and offshore survey. The US Navy's Lionfish system is based on REMUS 300; a 2023 contract covered an initial nine vehicles with options that could expand the programme to 200.
