The Starhammer missile was designed as a Field Replacement for the Pathfinder Ship Pegasus'sdepleted stock of Hammerhead missiles. It is similar in design and carries a warhead of similar yield. It can be distinguished from the Hammerhead by the yellow fins on its aft section.

The Starhammer was not a completely adequate replacement weapon, and were reputed to be somewhat unreliable, either failing to detonate upon reaching the target; or sometimes exploding short of the target.
