AN/ALE-39 Countermeasures Dispensing System

The system dispenses expendable payloads that consist of chaff, flares, or RF jammers, either individually or in groups. Three dispensers are installed in the aircraft, one on each side of the fuselage and one on the centerline on the fuselage bottom.

Search Store System

The search store system has the necessary equipment and accessories to carry and release sonobuoys. Also, the sono system can carry and release several other search-related stores.

Part of the search store system consists of unpressurized size A sonobuoy launch tubes (SLTs). These are installed in the underside of the aircraft fuselage. There are 60 SLTs. The SLTs are not accessible from the pressurized aircraft cabin (flight station); therefore, the designation "unpressurized."

The SLTs maybe reloaded only from the outside of the aircraft. Look at figure 15-33. It shows the arrangement of the SLTs as you look up at the lower fuselage.
