The USS Quasar (NCC-M06) was an Antares-class cargo ship in service to the Federation Starfleet in the mid-23rd century. Captain Allen Clark served as the ship's captain starting in the early 2260's and Clause Elberg as his chief engineer starting in 2265. Elberg would leave the ship in 2268 for earth to work on a new starship project at the Heisenhoff research post in Munich Germany. Clark would continue on as the ship's captain. (Star Trek: Eagle)
