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.
