FACILITY MAJOR SPACEDOCK

REGION TARSAS / VESPER MARCH

Starbase 74 is the primary Starfleet facility in the Vesper March. Located in orbit of Tarsas, it is one of Starfleet's large spacedock-class installations, capable of enclosing a starship for repair, refit, resupply, and crew rotation. For vessels assigned to the March, it is the nearest true home port before the routes thin into the frontier.

The station was badly damaged during the Borg invasion of 2381 and spent two years under reconstruction. Its recommissioning was not a return to quiet interior service. Starbase 74 was rebuilt as a forward operating base, relief hub, frontier gateway, and monitoring station for the Tholian-facing approaches north of the March.

Facility Profile

Type	Major Starfleet spacedock, orbital command facility, refit point, and regional logistics centre.
Location	Tarsas system; inner edge of the Vesper March and practical doorway between the Federation interior, Eventide, Bynaus, and the deeper frontier.
Current Status	Active and rebuilt after the 2381 Borg incursion. Operating under heightened regional watch protocols in December 2385.
Command Role	Seat of Starfleet's regional authority in the Vesper March, including task force command functions, ship assignment coordination, and secure fleet communications.
Civilian Interface	Relief shipping, controlled diplomatic arrivals, commercial support traffic, Bynar technical liaison, and transfer routing for Eventide-bound personnel and supplies.
Classification Note	General facility role is public. Detailed defence grids, sensor tasking, contingency staging plans, and intelligence annexes remain restricted.

History and Rebuild

The Tarsas facility grew out of the 23rd-century Starfleet survey and settlement push into what is now called the Vesper March. Early survey routes, scattered outposts, and civilian frontier traffic made the system a natural logistics point. By the early 24th century, Starbase 74 had become the region's principal Starfleet installation.

For much of its service life, the station supported routine patrols, exploration assignments, Bynar technical liaison, civilian shipping, and repair work on ships moving between the Federation interior and the southern frontier. As the Federation's attention shifted elsewhere during the Cardassian border crisis, the Dominion War, reconstruction, and the early Typhon Pact cold war, the March became quieter. Starbase 74 remained, but it carried more of the region's weight with fewer ships available to share it.

The Borg invasion changed the station's meaning. Damage from the 2381 crisis turned Starbase 74 into one more visible scar in a Federation full of scars. The decision to rebuild it as a forward operating base was therefore practical and symbolic at once. Starfleet needed a stronger regional anchor, but it also needed to prove that damaged places could be repaired without becoming monuments to fear.

Regional Functions

Open Functions Refit, repair, and resupply for Starfleet vessels operating in the Vesper March. Relief convoy coordination for Eventide and other post-invasion support routes. Fleet communications relay and secure briefing point for regional commands. Personnel transfer, medical referral, shore leave routing, and hearings. Diplomatic and technical liaison with Bynaus, Eventide, and approved visiting delegations.

Restricted Functions Long-range monitoring of Tholian-facing routes and the northern buffer region. Sensor fusion with edge watchposts, patrol assets, and automated survey relays. Threat assessment for indirect Pact-linked activity in the March. Contingency planning for rapid Starfleet concentration if the region destabilises. Secure storage and review of compartmentalised operational reports.

Classified Operational Annex

Tholian Watch	Starbase 74 maintains continuous analysis of patrol patterns, buffer incidents, subspace irregularities, and traffic anomalies along the northern approaches. Tholian activity is usually sparse, ambiguous, and politically sensitive.
Regional Staging	The station is rated to concentrate Starfleet vessels, relief assets, evacuation capacity, and command staff if the March destabilises. Routine operations remain proportionate and visible rather than escalatory.
Intelligence Handling	Reports involving Tholian movements, Romulan cover activity, Tzenkethi-linked intermediaries, unexplained Hovath signals, and edge-watch incidents are routed through restricted channels for command review.

Relationship to Nearby Nodes

Eventide	Nearest major civilian Federation community, approximately 11 light years from Starbase 74 — roughly ten days at warp 6. Relief shipping and Starfleet support pass through the station, but Eventide's civilian administration resists militarisation.
Bynaus	The Bynar home system and one of the March's most important technical partners. Bynar specialists support computer systems, diagnostics, data recovery, and complex technical investigations when assigned.
Ulysses Watch Routes	Western and northwestern edge-watch routes contribute to early-warning coverage. Detailed station records and active incident files are compartmentalised.
Tholian Buffer	The politically sensitive northern pressure zone. Starbase 74 is responsible for maintaining a clear regional picture without provoking avoidable escalation.

For crews assigned to the March, Starbase 74 is less a destination than a promise that the Federation has not abandoned the map. Beyond it lie Eventide's amber light, Bynaus's quiet brilliance, the edge watchposts, the Tholian-facing routes, and the deeper frontier. The station cannot solve the March by itself. It can keep the lights on while others try.
