HII announced the delivery of first two Lionfish small uncrewed undersea vehicles (SUUVs) to the U.S. Navy under a program that could scale to 200 vehicles, with a contract value exceeding $347 million. Lionfish is based on HII’s REMUS 300 platform, a modular, open-architecture SUUV engineered for multi-mission adaptability and the program was developed in collaboration with the U.S. Navy and Defense Innovation Unit (DIU), to accelerate the adoption of dual-use commercial technologies into U.S. Department of Defense programs.
