The Acamarian starship was a small spacecraft utilized by the Acamarian-Gatherers during the mid-24th century. These vessels were armed with phasers, and forward and aft shields, but were greatly outgunned by a Galaxy-class starship.
In 2366, the USS Enterprise-D sought a Gatherer ship commanded by Chorgan, in order to conduct discussions between the Acamarians and the rogue Gatherers. The Enterprise was fired on by the Gatherers' ship, but easily disabled its forward shield. Diplomatic talks were later held aboard the ship, discussing the reunification of the two peoples.
