Starbase 39-Sierra is Starfleet's main hub for operations near and beyond the Romulan Neutral Zone.
Starbase 39-Sierra serves as an important Federation starbase near the Romulan Neutral Zone since at least the early 2360s. Over the past decades the starbase played a major role in Federation-Romulan relations and served as an intelligence base for Starfleet.
The starbase was also the hub for rescue and relief efforts after the destruction of Romulus by the Hobus supernova. As of 2409, it is commanded by Admiral T'nae, and the primary base of operations on the Romulan Front.
