Fleet Dilithium Mine
The Fleet Dilithium Mine is a fleet holding, i.e., a dilithium mine run by a fleet and operated by Reman contractors. The Fleet Dilithium Mine System is located in the Beta Ursae Sector Block and it provides similar amenities as the Fleet Starbase, including mail, exchange, and bank terminals as well as special Duty Officer assignments and daily mining missions. It has identical maps between Klingon and Federation fleets.

Dilithium Mine projects can be accessed through the Dilithium Mine filter in the Holdings tab of the Fleet panel.
The Dilithium Mine projects are designed to take less time and resources to complete, as opposed to the resource-intensive Fleet Starbase Projects. Contrary to the Embassy, Dilithium Mine projects often require a Dilithium Mine Provisions instead of Refined Dilithium. Also, instead of the three Starfleet tracks present in the Fleet Starbase advancement process, only two tracks (Trade and Development) are present in the Fleet Embassy advancement process.
- Unlocking higher Trade tiers will grant access to provisionable rewards such as Advanced Engineering consoles, provide upgrades to the Embassy's appearance.
- Unlocking higher Development tiers will grant upgrades to access to provisionable rewards such as Advanced Fleet Warp Cores, Miner Duty Officers.
