Due to ongoing PvE queue and reward balance changes in Delta Rising, some dilithium reward amounts listed below may be incorrect.[1][2]

In Star Trek Online, Dilithium is a major form of currency predominantly earned and used in the end game. Players can use dilithium to purchase various things ranging from new ships when the player reaches a new rank to new officers, equipment (Space and ground), upgrading or re-engineering equipment, and via crafting materials.

Dilithium is further subdivided into 2 separate sub-currencies:

Each character has a 10 million Dilithium Ore balance limit and also a 10 million Refined Dilithium balance limit at any given time. Any Dilithium Ore or Refined Dilithium received to exceed these balance limits would be lost.

All Task Force Operations, including STFs and Special Events accessible from the TFO queue menu, grant a set amount of dilithium upon completion according to their difficulty level:

Normal - 360

Advanced - 720

Elite - 1,440

You may also choose to play a Random TFO, which will grant a random bonus reward of 500 to 2500 on Normal difficulty, or 700 to 3500 on Advanced difficulty.

Fleet actions [ edit | edit source ]

Fleet actions were older Task Force Operations that rewarded 480 for space, and 640 for ground maps. [5] There was also a daily mission for a random fleet action rewarding 960 and 50 [6]. They are currently unavailable.

Foundry has been shut down in April 2019.

Authors of user-generated missions can also be donated 25, 50 or 100 (refined!) by any player who completes their missions.

Duty Officer Assignments [ edit | edit source ]

Most Duty Officer Assignments provide a small amount of Dilithium (usually between 5 to 50 , with 125 to 150 on critical success) and a few provide larger quantities.

Reputation System [ edit | edit source ]

All projects rewarding 800 or 2000 reputation points give 140 or 340 , respectively. There are also special projects which grant more dilithium:

Continued support projects are more profitable than exchanging marks via "Ongoing Efforts" Projects in the long term as they offer a better mark to dilithium ratio (~1:23 vs 1:10) but need to be reslotted and filled once per hour for maximum efficiency.

Dilithium Vouchers [ edit | edit source ]

Q: What are “Fleet-Only Dilithium” and “Reputation-Only Dilithium”?

A: These are special Vouchers that fulfill the same purpose as existing Dilithium, but can only be used to fulfill Project requirements for the respective features, either Fleets or Reputations. These Dilithium Vouchers does not need to be refined, and cannot be traded for Zen. Projects that require Dilithium will deduct from the appropriate Voucher pool before deducting from your Refined Dilithium.
