Outpost 4
Outpost 4 was an outpost constructed a mile deep on an asteroid of almost solid iron by Starfleet in 2160. The outpost's protective shield was made of cast rodinium. This outpost was one of seven Earth Outpost Stations located on the Federation side of the Federation-Romulan border in Sector Z-6. This sector was in Galaxy Quadrant YX-12-114, which was a minor quadrant of the Beta Quadrant. (TOS: "Balance of Terror"; PIC: "Disengage")
History
The outpost was under the command of Commander Hansen Al-Salah by 2259. Under a retrofit directive, the USS Enterprise and the USS Cayuga delivered state-of-the-art matter synthesizers and a set of fully automated mining craft to Outpost 4. (SNW: "A Quality of Mercy")
The Enterprise arrives at Outpost 4 after it was attack by a Romulan Bird-of-Prey.
In 2266, Outpost 4 came under attack by an unknown starship that was later discovered to be Romulan Bird-of-Prey. Although protected by full deflectors, the outpost was hit by a powerful high-energy plasma torpedo that completely blew out the outpost's deflector shield, as well as taking out its phasers and killing its weapons crew. The second attack by the plasma torpedo hit the outpost, unprotected, resulting in the base's disintegration.
Within the next century, this outpost had been replaced with a new outpost bearing its name. In 2366, this outpost received a warning from Starfleet Command about an alleged Romulan base on Nelvana III. (TOS: "Balance of Terror"; TNG: "The Defector")
