BOMB BAY CONFIGURATION.— There are four primary pylon assemblies (fig. 15-23) provided for carrying a maximum of eight bomb bay stores. The pylon consists of two BRU-12/A bomb racks mounted between two pylon ends. The BRU-12A bomb rack (fig. 15-24) is a modified MAU-38 series bomb rack. The BRU-12/A is interchangeable with the MAU-38, and installation, operation, maintenance, safety, and testing procedures are the same. There are three 1,000- or 2,000-pound class store pylon assemblies (fig. 15-25) provided for carrying a maximum of three 1,000- or one 2,000-pound class weapon. The pylon assembly consist of a BRU-14/A bomb rack with mounting adapters on station 4C. The Aero 1A adapters provide the BRU-14/A bomb rack with 30-inch suspension and load capabilities. Figures 15-26 through 15-31 show the various wing stations and bomb bay equipment configurations. For more information on the P-3 aircraft, refer to Airborne Weapons/Stores Loading Manual, NAVAIR 01-75PA-75. S-3 AIRCRAFT The S-3 (fig. 15-32) weapon control system has the units, panels, switches, logic circuits, interfaces, computer, and controls necessary for selecting, arming, and releasing the kill or search stores. Status lights indicate store selection errors and stores go or no-go status. Electrical jettison release systems are used to release or eject all the wing stores and all search stores of the S-3 aircraft. Armament Control Panel The armament control panel (ACP) provides the pilot with control for the manual delivery of forward-firing weapons, droppable stores, and the release of the SAR sonobuoy. 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. A1. A2. A3. A4. A5. A6. A7. A8. REVIEW NUMBER 2 ANSWERS TO QUESTIONS Q1. THROUGH Q8. In the F/A-18 aircraft, the armament safety override switch is located on the maintenance panel in the nosewheel well. The jettison modes of the F/A-18 aircraft include (1) emergency, (2) selective, and (3) auxiliary. If the emergency jettison is selected on the F/A-18 aircraft, all weapons from the five pylon stations are released. The auxiliary jettison mode is used in the F/A-18 aircraft when emergency and/or selective jettison fails. It is a gravity jettison mode. The AN/AWW-4 fuze function control system gives the F/A-18 aircraft the capability of using electric fuzes. To suspend and fire the Maverick missile from the F/A-18 aircraft, you should use the BRU-32A and the LAU-117/A combination. You should use the LAU-118/A to suspend the AGM-88 HARM missile on the F/A-18 aircraft. The LAU-115C/A missile launchers used on the wing pylon stations of the F/A-18 aircraft to suspend and launch an AIM-7 Sparrow missile. 15-22
