Bomb Release System

The bomb release system provides the aircraft with capabilities for release of conventional weapons. The system uses the BRU-32, BRU-33, BRU-41, and BRU-42 gas ejector bomb racks for suspension and release of weapons. Normal release is provided in four electrically controlled modes of operation. The system

consists of the A/G weapon release switch and weapon control system's basic controls and components.

AN/AWW-4 Fuze Function Control System

The AN/AWW-fuze function control system gives the aircraft the capability of using electric fuzes. The system uses the Mk 39 bomb arming unit in the BRU-32/A and BRU-33/A bomb racks. The Mk 39 bomb arming unit denies all voltage to the weapon until it has actually separated from the bomb rack. Voltage is supplied by the PP-6419 power supply to the bomb arming unit through the aircraft wiring. There are four voltages selected on the DDIs. When release is initiated, voltage is supplied through an interconnecting cable to the weapon during the first few inches of fall of the weapon. No voltage is supplied to the bomb rack until the bomb release switch is pressed. The system consists of the PP-6419 power supply and the armament system's basic controls and components.

Rocket Firing System

The rocket firing system gives the aircraft the capability to fire rockets. The system uses the BRU-32/A and BRU-33/A bomb racks for suspension of the rocket launchers. When the bomb release switch is pressed, voltage is supplied through aircraft wiring to the vertical ejector rack (VER). Wiring within the VER allows the rocket to fire. The system consists of the armament system's basic controls and components.

Walleye Guided Weapon System

The Walleye guided weapon system gives the aircraft the capability for release and guidance of a Walleye weapon. The system uses the BRU-32/A bomb rack, bomb release system, and the AN/AWW-4 fuze function control system for fuzing. Video is supplied from the weapon through the aircraft wiring to the DDIs. No voltage is supplied to the bomb rack until the bomb release switch is pressed. The system consists of the CAGE/UNCAGE switch and the armament system's basic controls and components. The CAGE/UNCAGE switch is on the throttle. When the switch is pressed, it cages/uncages the weapon selected.

The AN/AWW-9B, AN/AWW-12A, and AN/AWW-13 data link systems are used with the Mk 21 and Mk 27 Walleye weapons and with the Walleye guided weapon system. The data link systems provide control and guidance to these weapons by using a data pod that is externally mounted to the aircraft. The systems use the BRU-32/A bomb rack. Video is

supplied from the weapons and pod to the DDIs through the aircraft wiring. The systems consist of the armament system's basic controls and components.

AGM-65 Maverick System

The AGM-65 Maverick system gives the aircraft the capability to fire a Maverick missile. The system uses the BRU-32/A bomb rack and the LAU-117/A launcher for suspension and firing of the Maverick missile.

AGM-88 HARM System

The AGM-88 HARM system gives an aircraft the capability to fire a HARM missile. The system incorporates the BRU-32/A bomb rack and the LAU-118/A launcher for suspension and firing. Control of the missile is supplied through the armament computer.

AIM-7 Sparrow Fire Control System

The AIM-7 Sparrow fire control system gives the aircraft the capability to fire an AIM-7 missile. The system incorporates the LAU-116/A launcher for fuselage stations and the BRU-32/A bomb rack with the LAU-115C/A launcher on wing pylon stations for suspension and firing. Control of the missile is supplied through the armament computer and the radar system.

AIM-9 Sidewinder Fire Control System

The Sidewinder fire control system gives an aircraft the capability for firing an AIM-9 missile. The system uses the LAU-7 launcher for wing tip stations and the BRU-32/A bomb rack with a LAU-115C/A launcher configured with the LAU-7 launcher on wing pylon stations for suspension and firing. Control of the missile is supplied through the armament computer.

M61A1 20-MM Gun System

The M61A1 20-mm gun system gives an aircraft the capability to fire this gun. The system enables selecting, arming, and firing. Depending on the mission objective, the gun can be operated in the air-to-air (A/A) or air-to-ground (A/G) computer mode. There are two A/G modes-continuously computed impact point (CCIP) and manual (MAN). There are three A/A modes-director, disturbed, and cage. Control of the gun is supplied through the SMP. No voltage is supplied to fire the gun until the trigger switch is pulled and all landing gear is up and locked. The gun fire control

system consists of four subsystems-the gun and associated ammunition feed, hydraulics, gun gas purging and ammunition cooling, and gun electronics.
