D19b Nefarious Class Destroyer image from Planets Nu
The with the right friendly code, D19b's glory device will cause it to explode when an unfriendly cloaked vessel enters the area. This explosion damages all ships in the area, exposing the cloaker. While perhaps not as good as a Loki, there are no races with D19b immunity and D19bs give the Fascists a rudimentary but effective defense against cloaking ships.
pop - explode the ship (after movement)
trg - explode the ship if a cloaked ship is detected (after movement)
(In Planets.nu, ships with glory devices don't need fuel to self-destruct; but in earlier versions of Host, fuel is required for these FCs to work.)
