Mars Defense Perimeter spacecraft

The mighty defenders of Earth

Mars Perimeter Defense Ships were only seen in part two of TNG "Best of Both Worlds", attempting to intercept and destroy or repel a Borg Cube that was approaching Earth. Only three were seen.

Specifications

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 are armed with phasers and photon torpedoes or behave more like long-range guided missiles.
• It is not clear whether they are capable of warp speed or are limited strictly to impulse speeds.
• 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.
