Mars Defense Perimeter spacecraft
We know almost nothing about these spacecraft.
- It is not clear whether they are manned warships or drones of some kind.
- It is not clear whether they have warp capability or are limited to impulse speeds.
- It is not clear whether they are armed with weapons like phasers and photon torpedoes or behave more like long-range missiles.
- It is not clear whether they have shields to protect them from enemy fire.
What is clear is that the Borg ship made short work of them, destroying each with a single weapon pulse.
According to the Star Trek Encyclopedia, these ships are unmanned drones.
