Construct Defense Platform B. is a station mission in Star Trek Fleet Command that asks you to build your second Defense Platform to strengthen your station’s defences. It has one objective, needs only warp 1 to start and finish, and the game lists a recommended level of 1. The reward is 500 Tritanium and two 3 Minute Repair Speed Ups. Finishing it unlocks the mission to upgrade Defense Platform B to level 2. The reward covers the Tritanium the platform costs to build.
Construct Defense Platform B. objectives
There is a single objective and no choice split:
- Construct Defense Platform B.
No system is named and no hostile is listed. The mission clears when Defense Platform B is placed at level 1.
Where and what warp
Warp 1 to start and warp 1 to complete, with no pickup system. Everything happens on your station.

Defense Platform B cannot be placed until you research Defense Platforms to level 1. The game lists these first-level costs:
