The USS Maat (NCC-1794) was a Constitution-class Federation heavy cruiser starship of the Achernar-subclass, ordered for construction in the 23rd century, named for the star Maat.
Construction of Maat was authorized by the Starfleet appropriation of stardate 5930. (ST reference: Star Fleet Technical Manual)
- The stardate given would seem to suggest this ship was ordered during the TAS era. It is not positively known if this vessel was built, only that it was authorized.
