It is on the capital weapon tab. Perhaps there is the tech level or era issue? Although castrum must be available after the era of the development of screen launcher.

At least on 50.11 it shows normally so anything on the current commit did cause the error.

Updated to 0.50.12-nightly-2026-03-24, error is still present.

Screenshot show both craft already equipped with screen launcher (Castrum) and a new blank WarShip set to 3145 and Experimental tech level so anything like that is accounted for.
