A Mighty Arsenal is a Star Trek Fleet Command mission in which you gather a stockpile of weapons. It is recommended for level 29, starts at warp 1 and needs warp 24 to complete. You collect the weapons in Leone, donate 1M Tritanium, defeat 15 hostiles of level 27 or higher, then return to your station. There is no scripted boss. The reward is all speed ups, 33 3 Hour Speed Ups and 100 1 Hour Speed Ups, which adds up to 199 hours of build or research time.
A Mighty Arsenal objectives
There are four objectives and no choice split:
- Get the weapons. Location: Leone.
- Donate 1M Tritanium.
- Defeat 15 Hostiles of Level 27 or higher.
- Return to your Station.
Leone is the only named system. After picking up the weapons there, you make a 1M Tritanium donation, then work through a kill count of 15 hostiles at level 27 or above. The kill count does not name a system. The final step brings you home.
Where and what warp
A Mighty Arsenal starts at warp 1 and needs warp 24 to complete. Leone is the one fixed stop. The recommended level is 29, two above the minimum level of the hostiles you need to beat.
A Mighty Arsenal rewards
| Reward | Amount | Total time |
|---|---|---|
| 3 Hour Speed Up | 33 | 99 hours |
| 1 Hour Speed Up | 100 | 100 hours |
Completing A Mighty Arsenal also unlocks the next mission in the storyline.
What the speed ups are worth
Together the two stacks come to 199 hours, a little over eight days. At level 29, that is enough to take a real bite out of a long upgrade. For comparison, Operations 30 lists an unboosted build time of more than 12 days, so this one mission covers well over half of it.
The 1 Hour Speed Ups are the more flexible of the two, since they fit shorter timers without waste. Save the 3 Hour Speed Ups for the long builds.
How it compares with nearby missions
| Mission | Recommended level | Warp to complete | Donation | Combat | Rewards |
|---|---|---|---|---|---|
| Sanctum | 29 | 20 | None | 10 hostiles of level 28 or higher | 55,000 Dilithium, 4 30 Minute Speed Up |
| A Mighty Arsenal | 29 | 24 | 1M Tritanium | 15 hostiles of level 27 or higher | 33 3 Hour Speed Up, 100 1 Hour Speed Up |
| A Family Reunion | 30 | 26 | 1.5M Tritanium | Guard in Ascher, about 296,419 | 21 3★ Uncommon Refined Crystal, 38 Augment Credits, 1 Day Peace Shield |
Of these three, A Mighty Arsenal pays by far the most time. Sanctum asks for fewer kills but pays only two hours of speed ups.
Tips
Have 1M Tritanium on hand before you reach Leone. The donation is the objective right after the weapons pickup, ahead of the kill count.
Pick hostiles at level 27 or higher. The objective sets that floor, so lower-level targets will not count toward the 15.
Bring a combat ship that can take repeated fights. Fifteen kills is the biggest count of the three missions compared above.
Double or Nothing is a neighbouring mission in the same storyline. Sanctum and A Family Reunion have their own pages, and every mission by level is on the mission guide.
