HII and Hitachi Lock In Multi-Year REMUS 300 UUV Production Agreement

POCASSET, Mass., July 01, 2025 (GLOBE NEWSWIRE) -- HII (NYSE: HII) announced the order from Hitachi, Ltd. (Hitachi) for more than a dozen REMUS 300 small uncrewed undersea vehicles (SUUVs) under a program that will deliver the vehicles over multi-years.

HII’s REMUS 300 platform is a modular, open-architecture SUUV engineered for multi-mission adaptability and was the commercial basis for the U.S. Navy’s Lionfish program.

The procurement by Hitachi builds on a long-standing relationship with Japan, an important U.S. ally in the Pacific region. The REMUS 300 platform is in service with several nations worldwide and offers critical interoperability with partner and allied forces.

“This procurement represents a key sale milestone for the REMUS 300 commercial program,” said Duane Fotheringham, president of Mission Technologies’ Uncrewed Systems business group. “We greatly appreciate the confidence Hitachi has placed in us. The success of our commercial REMUS 300 vehicles is a result of our work in the international markets and the high confidence our customers place in REMUS products. These vehicles deliver critical mine-hunting capabilities and flexible payload options to our allies and partners.”
