The Imperial O-BATS is a new weapon, designed to negate
planetary defenses at a much lower cost than traditional head on
attacks, or complicated ground assaults. These ships are launched
toward the target planet in groups of around 100, with their solar
panels closed, and their rather primitive anti-sensor cloak engaged
(+1D to opponent's sensor checks). Once they all are within range
of their target, their panels unfurl, and they take aim against
planetary defensive weapons. The Ion Cannon of the O-BATS is of
limited range and power, but it can penetrate the planetary
shields. As soon as the satellites open fire, Imperial support
craft move in to defend them against enemy starfighters. Once the
planetary weapons are down, the O-BATS immediately open fire on the
planetary shield generators. Once that target is eliminated, they
attempt to orient on any enemy starships that come their way.
After the space battle is over, the surviving O-BATS are gathered
up by the Star Destroyer that launched them, and repaired for their
next mission. O-BATs are not self repairing, and they operate on
a combination of solar power and stored fuel, that only lasts for
three hours.
