Star Trek Expanded Universe

Starbase 11 was a Federation facility, in use from the 22nd to at least the 24th centuries. Located in the Saken sector, it was the closest base to Planet Q, and had the facilities to repair numerous starships.

In DIS: "If Memory Serves", Starbase 11 is said to be two light-years from Talos IV.

It was located on a planet named Yko. It was described as having "a constant tropical climate, brilliant blue oceans, and lush green forests." (Star Trek: The Next Generation novel: Moments Asunder)

22nd Century[]

Starbase 11 was constructed by Terrans ca. 2150, shortly before the Earth-Romulan War; it was "one of the few Earth facilities to be constructed planetside." (Star Trek: New Worlds, New Civilizations).

Later that year, on stardate 3012.4, after suffering severe delta radiation poisoning, Fleet Captain Christopher Pike was sent to Starbase 11 where he received the best medical treatment at the base's Sector General Hospital.

The USS Saratoga docked at Starbase 11 on stardate 9618.9 and shortly thereafter Captain Edward Stanfield was informed of his transfer to the command of the USS Valkyrie.

The combined power of the Starfleet and Klingon ships drove the Cardassians away. (Star Trek: Pendragon)

Shortly after the end of the Dominion War in 2375, the starbase commemorated 225 years of continuous service to first the Earth Starfleet and then the Federation Starfleet. Admiral Michael Carlin had been in command of Starbase 11 for 28 years.
