RB-79N Fisheye

The Ball unit was also used in environments other than space. The RB-79N Fisheye was designed for underwater use. The generator output was increased to 425 kW(as compared to the 400 kW of the other Ball configurations) and a multiple barrel long spear launcher was mounted to replace the 180 mm cannon. The manipulators were also enlarged for melee combat. This type had a single propeller instead of two thrusters on the back of the unit.
