Accuser-class

The Accuser-class dreadnought was originally designed and put into service by the Klingon Empire in the late 23rd century. But because of their intimidating size and formidable firepower, they were extremely expensive both to build and operate. Only a handful were actually completed when the Praxis Incident occurred, devastating the Empire's ability to field an interstellar fleet. As a result, only a few ever actually entered service, all of which were mothballed in the aftermath of Praxis.

The Accuser-class features a unique experimental beam weapon dubbed the Anti-Matter Field Projector. The AMFP drew antimatter directly from the ship's reactor and projected it along a modified tractor beam, creating a powerful energy weapon. While a very effective weapon, the AMFP's energy requirements were extreme, adding to the ship's already expensive operating costs and proving too taxing a weapon to deploy on smaller ships.

Starfleet Intelligence has only been able to confirm the existence of six distinct Accuser-class space frames between 2293 and 2340, one of which is confirmed destroyed and with none having been encountered by Federation forces. By 2340, Starfleet Intelligence has high confidence that the five remaining space frames account for most if not all of the existing ships of the class, but has low confidence about their status or whereabouts.
