Gulo-Gulo, Latin for Wolverine, was the final generation of submarine that used the Odyssey hull platform. Substantial upgrades to the propulsion system and controls were made for the ISR 14 in 2017. These improvements greatly increased the speed and maneuverability of the submarine and laid the groundwork for future submarine design. Mack "Reverse" Galante served as the pilot of Gulo-Gulo during ISR 14.
