Momentum and Inertia is a level 25 mission in Star Trek Fleet Command where you defend the Trill embassy. It is picked up in Beta Assembly, and needs warp 20 both to start and to finish. You reach the embassy, defeat a rebel ship at roughly 73,260 strength, beam the Ambassador aboard and take them to a medical facility in Gemet. The reward is six 3 Hour Speed Ups and 11,000 Dilithium, and completing it unlocks the next part of the chain.
Momentum and Inertia objectives
There are four objectives and no choice split:
- Reach the embassy. Location: Beta Assembly.
- Defeat the rebel ship. Location: Beta Assembly. Enemy strength is roughly 73,260.
- Beam the Ambassador on board. Location: Beta Assembly.
- Bring the Ambassador to a medical facility. Location: Gemet.
The first three objectives all happen in Beta Assembly. You arrive at the embassy, fight the rebel ship, then beam the Ambassador aboard. The last step is a trip to Gemet to reach a medical facility.
The rebel ship is the only fight, and at about 73,260 it is the step that decides whether your ship is ready.
Where and what warp
The mission is picked up in Beta Assembly. The game lists warp 20 to start and warp 20 to complete. Beta Assembly and Gemet are the only two systems in the mission.
The recommended level is 25.
Momentum and Inertia rewards
| Reward | Amount |
|---|---|
| 3 Hour Speed Up | 6 |
| Dilithium | 11,000 |
Completing the mission also unlocks the next part of the chain.
The Trill rebellion missions compared
Momentum and Inertia sits between two other missions about the Trill ambassador and the rebels. Current game data for all three:
| Mission | Recommended level | Warp to complete | Combat | Rewards |
|---|---|---|---|---|
| Daggers Out | 25 | 20 | 10 hostiles of level 23 or higher | 240 3★ Explorer Parts, 1 Day Speed Up, 50,000 Tritanium |
| Momentum and Inertia | 25 | 20 | Rebel ship at about 73,260 | 6 3 Hour Speed Ups, 11,000 Dilithium |
| Into Thin Air | 25 | 20 | 10 hostiles of level 23 or higher | 240 3★ Interceptor Parts, 80 3★ Explorer Parts, 335,000 Parsteel |
Daggers Out ends with a return to the ambassador in Beta Assembly, and Into Thin Air starts there too, meeting Senise and then the Trill ambassador. Momentum and Inertia is the one with a named ship to beat rather than a hostile count.
Tips
Bring a combat ship. The rebel ship at about 73,260 comes early, before you can beam the Ambassador aboard, so the fight blocks the rest of the mission.
Six 3 Hour Speed Ups add up to 18 hours of speed ups, the most useful line in the reward for most players. Save them for long builds or research.
Call Your Shot is also picked up in Beta Assembly at warp 20 and level 25, so the two missions pair well if you are working through the area.
Previous mission: Daggers Out. Next mission: Into Thin Air. Other missions by level are on the mission guide.
