William Masefield

William P. Masefield was a human male Starfleet officer who served during the 23rd century.

In 2284, Masefield held the rank of commodore and commanded the Baker-class USS Cooper. That year, the Cooper responded to a distress call from Rho Markessis VI with the landing party unexpectedly becoming involved in the planet's civil war.

After the incident on Rho Markessis VI, the Cooper was ordered to Arcanis IV near the Klingon Neutral Zone. (FASA RPG: Star Trek IV Sourcebook Update). Soon after its arrival, the vessel was diverted to the planet Axanar to search for a hidden Klingon base left over from the Four Years War. (FASA RPG: Return to Axanar).
