Earth Outpost Station

A partial map of Earth Outpost Stations along the Romulan Neutral Zone.

The Earth Outpost Stations were a series of at least eight outposts, constructed on asteroids, that were located in Sector Z-6, along the Federation side of the Romulan Neutral Zone. They were established by treaty after the Earth-Romulan War of the 2160s, allowing Earth, and later the Federation, to monitor the Neutral Zone.

In 2266, four of the eight outposts came under attack and were pulverized by a powerful high-power plasma weapon utilized by a Romulan Bird-of-Prey. Among the destroyed outposts were Outpost 2, 3, 4 and 8.

In 2364, a border outpost reported a contingent of seven Romulan battle cruisers within sensor range. The outpost sent out a distress call, which was responded to by the nearby USS Berlin, however, Starfleet also requested the presence of the USS Enterprise, NCC-1701-D--D in the area was a vital show of force against the Romulans. This was necessary because together, the outpost and the Berlin would have been outgunned by the battle cruisers, had hostilities erupted.

By 2367, the Neutral Zone outposts had expanded in number, at least up to Outpost 23. Additional outposts in the region included Outpost Sierra VI.
