Star Trek Fleet Command: Vi'dar Loop and Borg Refinery Guide

To establish a self-sustaining mid-game economy in Star Trek Fleet Command, unlock the Vi'dar at Operations 25 and cycle it daily through Borg hostile space and the Borg Refinery. The Vi'dar is a specialized interceptor engineered to harvest Inert Nanoprobes from Borg Tactical Probes. Refining these probes produces Active and Charged Nanoprobes, funding ship upgrades, Borg research, and daily faction reputation and credit packs.

Unlocking the Vi'dar at Operations 25

The Vi'dar becomes buildable once you construct the level 25 Shipyard at Operations 25. You should prioritize this ship immediately over standard faction combat vessels.

To build the hull without spending real currency:

• Collect 100 Blueprints: Accumulate blueprints through recurring Borg events, Saturday Cosmic Cleanup token exchanges, and event store redemptions.
• Save Event Tokens: Direct non-cash event payouts toward Vi'dar blueprints until you reach the 100-blueprint requirement.
• Avoid Using Standard Combat Ships for Harvesting: Standard interceptors, explorers, and battleships lack the specialized armor piercing, critical damage mitigation, and protected cargo capacity needed to harvest nanoprobes efficiently.

Delaying the Vi'dar build stalls mid-game progression, as the Borg Refinery remains locked behind nanoprobe harvesting.

Hunting Borg Tactical Probes

Inert Nanoprobes drop exclusively from Borg Tactical Probes located in dedicated Borg systems. Regular hostiles in standard systems do not drop Borg progression materials.

When routing your farming runs, balance hostile difficulty against repair costs:

• Target Levels 25 Through 28 Initially: Low-tier Borg Tactical Probes yield fewer nanoprobes per target, but they allow you to destroy dozens of hostiles in a single deployment before shields drop.
• Avoid High-Tier Probes Prematurely: Probes at level 29 and above hit with high-output energy weapons that rapidly drain shields, causing heavy hull damage and burning excessive Tritanium on station repairs.
• Fill Protected Cargo: Stay in the system until you fill the Vi'dar's specialized protected cargo hold, then recall the ship before sustaining catastrophic hull damage.

Optimal Bridge Crews for Mitigation

Because Borg Tactical Probes rely on energy weapon volleys, defensive damage-mitigation crews dramatically outperform offensive attack crews by extending your hull survival.

Use one of the following bridge configurations:

• Standard Hostile Mitigation Setup: Place Pike in the captain's chair, flanked by Moreau and Chen. Pike boosts officer abilities, Moreau reduces hostile weapon penetration, and Chen mitigates incoming energy damage.
• Borg Farming Setup: Place 5 of 11 on the bridge to increase hostile loot drops while boosting damage mitigation. This setup accelerates how quickly you fill your cargo hold.
• Crews to Avoid: Do not deploy burst-damage PvP pairings like Kirk and Spock. Raw offensive firepower without hostile mitigation depletes your hull too quickly during extended farming runs.

Upgrade Priorities and the Borg Refinery Loop

Refine your collected Inert Nanoprobes every 24 hours in the Borg Refinery to acquire Active Nanoprobes, Charged Nanoprobes, and progression credits.

Invest your early refined materials according to these operational milestones:

• Ship Components First: Allocate Active Nanoprobes into the Vi'dar’s impulse engines, warp core, shields, and weapons before spending materials on broad Borg research.
• Reach Tier 6 Before Heavy Research: Maintain component upgrades until the Vi'dar reaches at least Tier 6. Delaying non-essential research nodes keeps your ship scaling ahead of repair costs.
• Warp Range Milestones: Upgrading warp components expands your operational range into deep Borg systems, granting access to higher-yield level 29+ hostiles.
• Cargo Expansion: Upgrading cargo bays increases your protected nanoprobe limit, preventing hostile players from stealing your yield on your return flight.

Daily Borg Refinery Conversions

Once the Vi'dar reaches stable farming tiers, excess refinery conversions feed directly into daily faction advancement.

Redeeming these faction bundles daily bypasses the standard faction mission bottleneck, significantly cutting the time needed to unlock faction ships such as the Enterprise, D4, and Augur.
