Joint Direct Attack Munitions The F-22 also will have a modernized version of the proven M61 internal gun and growth provisions for other weapons. The aircraft also will be capable of carrying joint direct attack munitions (JDAMs) and other ground-attack weapons.
Air-to-surface capability The F-22 has a secondary role to attack surface targets. The aircraft will be capable of carrying two 1,000-pound joint direct attack munitions (JDAMs) internally and will use on-board avionics for navigation and weapons delivery support.
Specifications Designation � AIM-120 Type � Radar-guided medium-range air-to-air missile Contractors � Hughes Missile Systems and Raytheon Company Powerplant � Aerojet two-stage solid propellant rocket motor Guidance � Inertial midcourse, with active radar terminal homing Warhead � High explosive, directed fragmentation weighing 48 LB Dimensions � Length: 12 ft. 0 in.; Body Diameter: 7 in.; Fin Span: 1 ft., 6 in. (AIM-120C) Weight � 345 lbs. Performance � Cruising speed approximately Mach 4; Range: Approximately 30 miles F-22 Loadout � When the F-22 is in first-day-of-a-war combat configuration, all missiles are carried in the main weapons bay only. Typical combat load � Six AIM-120C. Three in each side of the main weapons bay with the center missile staggered ahead of the inboard and outboard missiles. The F-22 can carry four of the older, longer-finned AIM-120A if necessary.
AIM-9 SIDEWINDER
Specifications Designation � AIM-9 Nickname � Sidewinder Type � Heat-seeking (infrared) short range air-to-air missile Contractors � Raytheon Company and Loral Autoneutronics Powerplant � Thiokol Hercules Mk. 36 Mod 11 solid propellant rocket motor Guidance � Solid-state infrared (IR) homing Warhead � High explosive, blast fragmentation weighing 20.8 lb. Dimensions � Length: 9 ft. 5 in.; Body diameter: 5 in.; Fin Span: 2 ft. 1 in. Weight � 191 lbs. Performance � Maximum speed above Mach 2; Range: More than 10 miles F-22 Loadout � Two AIM-9M (One missile in each side weapons bay) NOTE: There are no plans to carry the AIM-9 in the F-22's main weapons bay.
GBU-32 JDAM Joint Direct Attack Munition
Specifications Designation � GBU-32 Type � JDAM is a tail guidance kit that converts existing unguided free-fall bombs into near precision-guided "smart" munitions. It also includes strap-on strakes that attach to the bomb's body for stability. Contractor � McDonnell Douglas Aerospace Powerplant � None Guidance � Inertial Navigation System (INS)/Global Positioning System (GPS) Warhead � For F-22, the JDAM tail guidance kit fits on the Mk. 83 1,000-pound-class conventional bomb Weight � Weight of the Mk. 83 bomb and tail guidance kit is approximately 1,015 pounds Performance � The combination of the stealthy F-22 and the precision capability of the GBU-32 allows the F-22 pilot to drop the weapon from altitudes of approximately 40,000 feet; Range: Approximately 15 miles F-22 Loadout � The GBU-32 is only carried in the F-22's main weapons bay. Typical combat load � Two GBU-32. One GBU-32 is carried inboard in each side of the main weapons bay. When loaded with GBU-32, there is still sufficient room in the F-22's main weapons bay to carry two AIM-120C air-to-air missiles (one in each side of the bay, in addition to the two AIM-9 Sidewinders in the side weapons bays), which means that even on a mission to attack ground targets, the F-22 retains significant air-to-air combat capability.
M61A2 20-mm Cannon
Specifications Designation � M61A2 Type � Six-barrel, hydraulically operated 20mm Gatling gun Contractor � General Dynamics Armament Systems Rate of Fire � 6,000 rounds per minute Rounds Available � 480 Effective Range � Several thousand yards
