escorts
target [read-only array of Entitys]
The ship’s deployed targets.
fuel

hasSuspendedAI
hasSuspendedAI [read-only boolean]
true if the ship has suspended AIs, false otherwise.

heatInsulation [read/write double]
The ship’s heat insulation factor. 1.0 is normal, higher values mean more resistance to heat.
isBeacon
isBeacon [read-only boolean]
true if the ship is a beacon (i.e., can show up on the Advanced Space Compass with a character indicating its identity), false otherwise. (See also: beaconCode)

true if the ship has a military scanner jammer which is currently active false otherwise.
maxCargo
maxCargo [read-only integer]
The ship’s cargo capacity.
