In the fictional Star Trek universe, two ships have been given the designation USS Bellerophon.
The USS Bellerophon (NCC-62048) was a Nebula class starship destroyed by the Borg at the Battle of Wolf 359 circa stardate 43997 in 2366. (The official spelling of NCC-62048 is Bellerephon, but this is assumed to be a misspelling.)
Bellerophon had to approach Pegasus while it drank from a well; Polyeidos told him which well—the never-failing Pirene on the citadel of Corinth, the city of Bellerophon's birth.
Bellerophon felt that because of his victory over the Chimera he deserved to fly to Mount Olympus, the realm of the gods.
The third HMS Bellerophon (1907) was the lead ship of a three ship class which were a follow up to HMS Dreadnought (1906) she fought at the Battle of Jutland.
