Insights

Defense Industry Analyst

HII's 750th REMUS UUV delivery confirms its dominance in naval autonomous systems with impressive global market penetration and platform longevity.

HII's milestone of delivering its 750th REMUS unmanned undersea vehicle (UUV) to the German Navy represents a significant achievement in the defense autonomous systems sector. With REMUS systems now deployed across 30+ countries including 14 NATO members, HII has established an impressive global footprint that solidifies its market leadership position.

The most compelling aspect of this announcement is the 90% operational rate of REMUS units delivered over the past 23 years. This exceptional platform longevity demonstrates both superior engineering and substantial lifecycle value—metrics that defense procurement officials prioritize when making acquisition decisions. The long service life translates to reduced total ownership costs and higher return on investment for military customers.

The REMUS platform's open architecture design enables rapid technology insertion and payload integration, allowing customers to adapt the systems for diverse missions including mine countermeasures, hydrographic surveys, intelligence gathering, and environmental monitoring. This versatility has clearly contributed to its market success.

Of particular strategic interest is the recent demonstration of REMUS deployment from Virginia-class submarine torpedo tubes. This capability significantly extends operational reach while reducing risk exposure for naval personnel. For investors, this submarine integration creates potential for additional retrofitting contracts across existing submarine fleets.

Germany's selection of the REMUS 300 reinforces HII's position as a trusted NATO supplier at a time when European defense spending is increasing in response to regional security concerns. This contract enhances HII's international revenue diversification while strengthening its position in the growing autonomous naval systems market.

LONDON, Sept. 10, 2025 (GLOBE NEWSWIRE) -- DSEI EXPO - HII (NYSE: HII), America’s largest military shipbuilder, and a leader in advanced unmanned autonomous technology solutions, today announced the completion of production of the 750th REMUS unmanned undersea vehicle (UUV) for a customer.

The German navy will receive the 750th REMUS, a REMUS 300, produced at the HII unmanned facility in Pocasset, Massachusetts.

This marks the continued global adoption of REMUS systems to support national security and maritime operations.

The REMUS line of UUVs is fielded in more than 30 countries, including 14 NATO members. Known for modularity, endurance, and proven performance, REMUS vehicles are deployed across defense, commercial, and research sectors for critical missions including mine countermeasures, hydrographic survey, intelligence gathering, and environmental monitoring.

Over 90% of REMUS units delivered in the past 23 years remain in service, demonstrating platform durability and lifecycle value both critical in defense acquisition decision-making.

The REMUS open-architecture design allows rapid payload integration, enabling mission-specific configurations and future tech insertions, key factors in maintaining operational relevance and cost efficiency over time.

“The 750th REMUS order is an achievement that reflects both the trust of our international partners and the innovation of our teams,” said Duane Fotheringham, president of the Unmanned Systems business group in HII’s Mission Technologies division. “We are proud to support Germany as it strengthens its undersea capabilities and look forward to continuing to advance unmanned solutions that enhance security and operational readiness worldwide.”

The German navy selection of REMUS underscores HII’s role as a key partner in NATO’s collective defense efforts, providing allies with reliable and mission-proven technology for evolving undersea challenges.

The REMUS UUV family delivers critical advantages across modern naval operations and the autonomous systems have been proven to operate independently or in conjunction with crewed platforms. This includes the recent successful demonstration of the launch and recover of REMUS autonomous undersea vehicles from the torpedo tubes of Virginia-class nuclear submarines. This capability will significantly extend mission range, reduce detection risk, and limit personnel exposure.
