The Ja'VaK class disruptor tank is a large hover vehicle used by the Klingon Empire.
These machines were created pre-Organian Klingon Isolation. The Ja'VaK class tanks were created to bring as much firepower on to the battlefield as possible. They were both cheap and easily manufactured. The majority of the chassis is occupied by a generator in the rear which powers shields, the roof mounted disruptor and the anti-gravity system. These tanks were piloted by two Klingon warriors; one driver and the other is a gunner.
These tanks were noted for their durability and were known to perform at the best of levels even in the most hazardrous of situations. This made it one of the most frequently seen vehicles used by Klingon military forces.
