Location

Deep Space K-7 was located within Federation space, in the Beta Quadrant, and near the borderwith the Klingon Empire. (DIS: "Choose Your Pain") The nearest Klingon outpost was only 3.26 light years away from the station. K-7 and this Klingon outpost were also in the same quadrant as Donatu V and Sherman's Planet. (TOS: "The Trouble with Tribbles") The station was over two hundred light years from Bajor. (DS9: "Trials and Tribble-ations")

In 2256, this station's location was labeled on the star chart "Alpha/Beta Quadrant Overview" in the ready room aboard the USS Discovery. (DIS: "Magic to Make the Sanest Man Go Mad")

In 2258, the station's location was labeled on a star chart seen on the main viewscreen of the USS Enterprise. (DIS: "Such Sweet Sorrow, Part 2")

In 2259, the location of this space station was labeled on a stellar cartography chart that was seen on the USS Enterprise's ready room viewscreen. (SNW: "Strange New Worlds", "Children of the Comet", "Spock Amok")

In 2399, the location of Deep Space K-7 was labeled on a Federation star chart that was in Fleet Admiral Kirsten Clancy's office at Starfleet Headquarters. (PIC: "Maps and Legends")
According to StarTrek.com, this station was located near the Mempa sector in the Beta Quadrant. [1]

History

Deep Space K-7's location near the Klingon border, December 2256.

The station was operational by at least 2256. (DIS: "Choose Your Pain")

In 2257, during the first Federation-Klingon War, this station was occupied by the Klingons. (DIS: "The War Without, The War Within")

In 2259, the USS Enterprise was assigned on a priority one mission to deliver vidium power cells to K-7. (SNW: "All Those Who Wander")

In the year 2268, Cyrano Jones, an interstellar trader, introduced a litter of tribbles to K-7, which quickly grew into an infestation. (TOS: "The Trouble with Tribbles")

The infestation coincided with the arrival of Federation undersecretary Nilz Baris, who transported several tons of the grainquadrotriticale to K-7, intended for cultivation on Sherman's Planet. Unbeknownst to Federation officials, the grain had been poisoned by Klingon spy Arne Darvin in collusion with the visiting crew of the IKS Gr'oth. It was not until hundreds of tribbles were found dead, gorged on the poisoned grain, that the contamination was revealed. Fortunately though, the plan was uncovered thanks to the tribbles and foiled by Starfleet Captain James T. Kirk and the crew of the USS Enterprise, who also happened to be visiting the station at the time. (TOS: "The Trouble with Tribbles"; TAS: "More Tribbles, More Troubles")

In the year 2373, an elderly Arne Darvin traveled back to K-7 of the past, where he planted a tricobalt bomb intended to kill Captain Kirk and prevent his own "dishonor". Darvin was ultimately caught by Captain Benjamin Sisko and the crew of the USS Defiant and returned to the 24th century. This incident caused some minor changes in the timeline to take place. In one instance, Miles O'Brien and Julian Bashir, disguised as members of Kirk's crew, became involved in a barbrawl between Klingons and Enterprise crewmembers. After the fight, Kirk lined up his officers for questioning. Prior to the temporal change, Freeman was questioned by Kirk, but the temporal incursion caused O'Brien to take his place.

Layout

The thirty decks of K-7 and the three outboard modules labeled K-A, K-B, and K-C mainly consisted of storage areas and industrial fabrication facilities. Among the recreational areas available on the station was a bar frequented by intergalactic trader Cyrano Jones. The manager's office featured a two-person transporter pad. The station had two docking bay for small starships and auxiliary space vessels. There was little space designated for quarters.

In 2268, the Class F shuttlecraft NCC-K7 and the Spacematic, Cyrano Jones' vessel, were stored in docking bay 2. (DS9: "Trials and Tribble-ations")
