The Devilfish, also known as the One Man Submersible Devilfish, OMS Devilfish Sub, or simply the Devilfish sub, was a compact submarine vehicle produced by Kuat Drive Yards. It saw service with the Grand Army of the Republic's clone SCUBA troopers throughout the Clone Wars. These Devilfish subs were notably employed during the Battle of Mon Cala and provided to the Gungan Grand Army as reinforcements. Following the Battle of Dac City during the rule of the Galactic Empire, seatroopers also made use of OMS Devilfish subs.
This military vessel, the OMS Devilfish, was specifically engineered for operations in aquatic environments. While it did not possess heavy armor, it compensated with rapid propulsion jets and a dual blaster cannon mounted at the front.
