REMUS is the legacy-prime of DEPLOY's defense-subsea cell: the established incumbent (2001 Hydroid/WHOI lineage, now HII) against which the new-defense XL-AUVs (Anduril's Ghost Shark and Dive-LD) are measured, the subsea analogue to MQ-9 vs the new-defense aerial cohort.
✔
The lineage is verified: REMUS dates to 2001, HII acquired Hydroid in 2020 for about $350 million, and the REMUS 620 (2022) offers up to 110 hours of endurance and 275 nautical miles of range.
Price
No reviewed price is on record. We do not treat unverified analyst estimates as pricing data. There is no consumer price. The REMUS family is defense procurement equipment sold on contract, so DEPLOY records zero price points rather than a consumer figure.
Availability
Internal use only
REMUS is sold to defense customers, not consumers. Built by HII's Mission Technologies division, the family is fielded across the US Navy and allied forces; a torpedo-tube-launched 'Yellow Moray' variant was fielded from the submarine USS Delaware in 2025.
Real-world status
HII's REMUS family (REMUS 100/300/600/620) is the legacy-prime of DEPLOY's defense-subsea cell: autonomous undersea vehicles for mine countermeasures, hydrographic survey, ISR, and electronic warfare, with a lineage dating to 2001 (Hydroid and Woods Hole Oceanographic Institution heritage; HII acquired Hydroid in 2020 for about $350 million). The REMUS 620 (introduced 2022) is a medium-class long-endurance UUV with up to 110 hours of endurance and 275 nautical miles of range. It is the established-incumbent counterpart to the new-defense XL-AUVs (Anduril's Ghost Shark and Dive-LD).
⚠
Cap-flag procurement figures: large ceiling numbers (such as a 200-vehicle order) are orders, not delivered counts. DEPLOY anchors on the fielded record (the Yellow Moray variant from USS Delaware in 2025), not the ceiling.
