Well, and have you ever seen anything that wasn't low-tech? The icon itself is a Hound.
I have attached an image. One can see
exactly how many and which hull. These are
exactly the (mothballed and other) ships of the fleet. No randomness, no uncertainty. The ships with a red lightning outline are
exactly the ships this suggestion concerns itself with, the rest are
exactly not.
You can get them in code via
List<FleetMemberAPI> ships = <fleetHandle>.getFleetData().getMembersListCopy();
for (FleetMemberAPI ship : ships) {
if (ship.isMothballed()) {
<do stuff>
}
}
