John Jason Harriman II, the son of Starfleet Admiral John "Blackjack" Harriman, was a human male in Starfleet in the late 23rd and early 24th centuries. He rose through the ranks rapidly, in part due to his father's influence, eventually being assigned command of the newly commissioned USS Enterprise-B in 2293. Despite a rocky start, he became one of the most well-regarded captains in the fleet.
Early Life
Harriman was born aboard the USS Sea of Tranquility and lived most of his childhood on a series of starships. Until his entrance into Starfleet Academy, He had never spent more than a few weeks planetside. This was a uncomfortable experience for Harriman as he found the sky in particular to induce agoraphobic reactions. After a few months however, he recovered and excelled in his studies. He studied the Romulan Star Empire in depth, an interest he had maintained after hearing stories of his grandfather's participation the Earth/Romulan War as told by his father. He graduated in three years on an accelerated program.
Aboard the Hunley
As a Lieutenant, Harriman served on the USS Hunley as the Conn Officer. During a disasterous conflict with the Romulan Vessel Daami and its commander Aventeer Vokar, the vessel was disabled and severely damaged, the majority of the senior staff killed during the attack. With a romulan boarding party on the way, Harriman was able to beam over to Daami and hold Vokar captive at gunpoint. Though Harriman was tempted to kill Vokar for what he had done, he was unable to, but was succesful in capturing the Daami and returning both ships to federation space. This incident would spark a fierce rivalry between Harriman and Vokar for over two decades.
Aboard the Enterprise
He resigned his command in 2311, following the Tomed Incident, and that same year, he was married to Amina Sasine. (TLE novel: Serpents Among the Ruins)
Liaison to S.C.E.
In 2371, Harriman, then an admiral, was Starfleet liaison to the Starfleet Corps of Engineers. (TNG short story: "Full Circle")
