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 weapons (Space and ground), deflectors and shields, and via crafting materials.

It is a time-based currency (~480 Dilithium Ore icon.png per 15 minutes of gameplay according to Cryptic) in that it is obtained from certain missions, mostly repeatable every 20 hours, that require time for a player to complete. The currency is given out as dilithium ore, which must be refined (up to 8000 per day) using the ship's Inventory Asset tab.

Dilithium can only be traded to other players for Zen Zen small icon.png via the Dilithium Exchange (Located in the More menu via the down-arrow, on the mini-map. It is also possible to set a keybind in the options menu to permit direct access via keystroke). Trade values are restricted to 50-500 refined dilithium Refined dilithium icon.png per Zen.



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

PvE queue

All STFs and event-type missions accessible form the PvE queue grant a set amount of dilithium upon completion according to their difficulty level:

  • Normal - 360 Dilithium Ore icon.png
  • Advanced - 720 Dilithium Ore icon.png
  • Elite - 1,440 Dilithium Ore icon.png

Fleet actions reward 480 Dilithium Ore icon.png for space, and 640 Dilithium Ore icon.png for ground maps. [3] There is also a daily mission for a random fleet action rewarding 960 Dilithium Ore icon.png and 50 Fleet Marks [4].

PvP and global PvE

Empire Defense

  • Faction KDF.png “Empire Defense: Borg” - 1440 Dilithium Ore icon.png
  • Faction KDF.png “Empire Defense: Cardassians” - 1440 Dilithium Ore icon.png
  • Faction KDF.png “Empire Defense: Federation” - 1440 Dilithium Ore icon.png
  • Faction KDF.png “Empire Defense: Romulans” - 1440 Dilithium Ore icon.png

Missions no longer rewarding dilithium

Duty Officer Assignments

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

Reputation System Projects

All projects rewarding 800 or 2000 reputation points give 140 Dilithium Ore icon.png or 340 Dilithium Ore icon.png, 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.



Duty Officers

Lt. Ferra at Starfleet Academy and Lt. S'stas at Klingon Academy are selling Duty Officers of Uncommon and higher quality for Dilithium.

Season 5 Conversion

For Season 5, players had many currencies converted to dilithium (at the following rates, up to the first 160,000 dilithium)[6]:
