The SM-53 Magazine converts the ALE-50/55 RF decoy system into an advanced infrared expendable decoy system. It does this in a flightline configurable manner, in that the only action required to prepare the system for flight, is to install the appropriate magazine
(ALE-55 RF decoy or SM-53 IR decoy).
The SM-53 capitalizes on the existing ALE-50/55 launcher system in three main areas:
1) It uses the ALE-50/55 chassis to house the SM-53 magazine.
2) It uses the ALE-50/55 conditioned/redundant power and (squib fire) commands sent from the cockpit.
3) It passes BIT information through the ALE-50/55 Launch Controller (IMPLC) back to the cockpit.
The SM-53 can be installed in aircraft equipped with ALE-50/55 decoy dispensers (such as the F-18E/F) with no aircraft modifications.
