This is an experimental larger Bird of Prey Heavy Frigate. It was rarely seen, and some in Starfleet even doubted it's Existence, but a few times, Starfleet Intelligence, who designated the ship VF-4A, documented around two vessels of the class built, that rarely saw combat, and were part of some fleet operations, including the "Time Trap" mission, when some Klingons had fooled Captain James T. Kirk in 2287 into thinking he was a century into the future and made his injuries sustained in a storm seem to be healed, taking him aboard the lead ship in a fleet of mostly D-12s, D-32s, L-42s, and K-22s, with the VF-4as being part of this fleet.
