This is the Firestorm class fusion pulse cannon. It is an adaptation of the fusion cannon which uses new gravimetric technology. It is specialized to deliver high velocity pulses of fusing hydrogen. The Firestorm is based on the idea of Connor MacLeod.
First, hydrogen collected for the reactor system is injected into the fusion initiation chamber. The hydrogen is then accelerated to 250,000,000 m/s with electromagnetic and gravimetric forces and packed into gravimetric field as it exits the barrel. A laser is then used to ignite fusion as the packet leaves the barrel. This weapon can be discharged at a rate of 1 packet/barrel/s.
