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.
