The three-barreled automatic weapon in the cupola could operate independently or be locked to the same point of aim as the main gun. Eight intake ducts pierced the upper surface of the hull, feeding air down to drive fans in armored nacelles below.
At rest, the tanks sat on their steel skirts. When the vehicles were under way, they floated on a cushion of air pressurized by the fans.At full throttle,the power required to drive a tank was enormous, and the fusion bottle which provided that power filled the rear third of the hull.
