BACKGROUND: The Sentinel class was designed to be a cruiser-sized partner to the Defiant-class Heavy Escort. Production delays caused by the Breen attack on the Sol System resulted in only one ship being finished before the end of the Dominion War, the class ship U.S.S. Sentinel, NCC-99724. Shortly thereafter, funding for the class was cut when opponents of a more militant Starfleet were able to persuade the Council that the ship was not needed. As the Sentinel had already been commissioned, Starfleet decided to keep it in service and has assigned it a mission to patrol the reestablished Demilitarized Zone.
NOTE; I am not an artist; I see this ship as resembling the Defiant but also with some things reminiscent of the Sovereign class. Anyone care to take a shot at drawing it?
