Passengers: 100 (battle droids, repair droids)
Cargo Capacity: None
Altitude Range: Ground level up to 30 meters
Cost: Not available for sale
Move: 21; 60 kmh
Fire Arc: Special (below tank)
Fire Rate: 1/5

Damage: 8D (piston), special (see Game Notes)
Game Note: The seismic hammer creates a shockwave, targets caught in the blast area take 5D physical damage, are blown 1D+4 meters distance and knocked to the ground. Furthermore the hammer creates a 50 meter wide by 30 meter deep crater. Displaced matter radiates from the center of impact in a wave, treat as Difficult terrain. On a failed result the defender is stuck in the displaced matter, if the roll fails by 10 or more, the target is buried (4D suffocation per round until rescued). Buildings and vehicles take double damage.
A modified version of the seismic tank was converted to an orbital spacecraft, removing the seismic hammer and converting the space to cargo. They were used to release a substance above the planet Ukio that adhered to the planetary shield, blocking light from half the planet, dropping surface temperatures and destroying crops.
Background: The seismic tank, also referred to as “seismic charge minelayer” or “seismic hover tank,” was a massive, fifty-five-meter-tall repulsorlift craft with a huge seismic driver in its core. Magnetic impellers guided the driver, which was almost frictionless, through a channel located in the center of the tank. The heavy metal core of the driver gave it an enormous amount of inertia as it fell toward the ground below. The impellers were also responsible for keeping the driver perfectly centered in the channel and for making sure the resulting shockwave did not travel up the shaft and into the rest of the vehicle.
Four repulsorlift generators carried the tank at heights of up to thirty meters, while stabilizing repulsorlifts lined the tank’s lower section. To result in its full gravitic force being intact upon impact, the repulsorlifts did not envelop the entire craft. This resulted in the tank being very unwieldy and slow. The seismic tank was operated from a topside command bridge by a team of battle droids. Repair droids monitored the driver, as misalignment could result in a shockwave ripping the vehicle apart. The tank was also capable of being modified for space flight and use as a chemical dispenser into planetary atmospheres.
