The USS Lionheart' (NCC-85301) was a Pendragon-class Federation starship in service in the late 24th century. Commissioned alongside the USS Caerleon in 2384, it was the third Starfleet vessel to bear the name, and the fifth ship of its class to be launched. (Star Trek: Pendragon) Mary Barranco was offered command of the Lionheart, but turned it down in order to remain aboard the USS Pendragon during Captain Sinclair's absence. (PDN: "Odyssey")
