The Epsilon IX station was a Federation Epsilon type deep space communications array and subspace transceiver station that was in service to Starfleet in the late 23rd century. This space station was located in the Beta Quadrant near the Federation-Klingon border. By 2273, was under the command of Commander Branch.
In that year, as the V'Ger crisis unfolded, Epsilon IX transmitted detailed information to Starfleet Command about the engagement, and subsequent destruction, by V'Ger of a Klingon cruiser task force led by the IKS Amar. Epsilon IX was subsequently destroyed by V'Ger as it passed near the station and probably misinterpreted its sensor scans as a hostile action.
Two models of Epsilon IX were mounted on two separate walls of the Starfleet Officer's Lounge in 2285. One was near where Admirals Kirk and Morrow had a conversation, while another was in the lounge's entry room. The station was later honored by Starfleet when a Regula type station was named Epsilon IX in honor of the destroyed station.
