Swarm-class battle droid

The Swarm-class battle droid was the Ssi-Ruuk equivalent to a starfighter.

Characteristics
Swarm-class droids were about two meters long, making them some of the smallest known starfighters. Because of their size and low production costs, Ssi-Ruuk vessels could carry hundreds of them into battle—at least 1,500 were present at the first Ssi-Ruuvi invasion of Bakura in 4 ABY.

They were tetrahedral and armed with four laser cannons, one at each vertex. These laser cannons could be turned through 360 degrees, giving the droid a wide field of fire, including the ability to fire backwards when chased.

Powered by entechment—which utilized the drained life sources of sentient beings usually P'w'ecks and occasionally even Humans—each droid used two life-forces. One operated the shields while the other piloted the fighter and operated the laser cannons and sensors. The life-forces in the battle droids received their commands from the Ssi-Ruuk command vessels via sensor arrays located on thrusters on each side of the vehicle.

Though they had fairly fragile hulls, the shield system had a unique ability to absorb and redirect incoming energy, similar to the Vangaard Pathfinder. The fusion thrust technology they employed was somewhat less advanced than equivalent Imperial systems and was more easily detected on sensors than many other fighters.
