Trampler
Most raids get easier once your Trampler can carry the crew, loot, and guns the run actually needs, because it is the walking base behind every deployment.
Stationary Turret Control starts paying off when the Trampler can spare both the slot and the 80 mm shell space to make controlled fire matter.
Stationary Turret Control only pays when the Trampler is built to support it. The weapon itself is not the whole decision; shell storage, firing angles, crew attention, and repair margin all come with it. If the run plan can keep 80 mm shells stocked and hold good shooting lanes, this mount gives the crew deliberate turret pressure. If ammo space is already tight, the mount usually steals more from the build than it gives back.
It comes through Trampler armament paths and uses 80 mm shells. In practice, the real gate is not finding the mount but having enough shell space and route time to justify it.

40 mm Autocannon is worth mounting when the Trampler can stay fed on 40 mm shells and keep a firing lane long enough to cash in on steady auto-gun pressure.
70 mm Shotgun Cannon makes sense when your Trampler can stay loaded with standard shotgun-cannon shells and actually press close fights.
80mm Naval Cannon makes sense when your Trampler can stay fed on 80 mm shells and actually take the kind of fight where a heavy cannon matters.
It pays off when the Trampler can hold angles, feed 80 mm shells, and stay repaired long enough for controlled shots to matter. That is when the mount adds real pressure instead of becoming cargo.
It falls off when shell space, repair room, or route tempo are already under stress. A mounted gun that the crew cannot afford to feed is usually worse than carrying the support space instead.
Yes, when the Trampler can actually support controlled fire with shell space, stable angles, and enough repair margin to stay in the fight.
The first check is whether the Trampler can hold safe firing angles, then whether shell storage and crew attention are strong enough to keep the mount useful.
