Huntington Ingalls Industries (HII) said Monday it delivered the first two Lionfish small uncrewed undersea vehicles to the US Navy under a program that could scale to 200 vehicles, with a contract value exceeding $347 million.

Based on its REMUS 300 platform, the company said Lionfish is designed to support critical undersea warfare needs, including mine countermeasures, intelligence, surveillance and reconnaissance, anti-submarine warfare, and electronic warfare.

The program was developed in collaboration with the US Navy and the Defense Innovation Unit to accelerate the integration of dual-use commercial technologies into US Department of Defense programs, it added.
