AIM 120

	
Located in the ventral bays, the F-22 is armed with six AIM-120C Advanced Medium-Range Air-to-Air Missiles (AMRAAM). Weapons armament on the F-22 turned out to be a controversial issue in the past. In preferred conditions, a fighter such as the F-22 with internal weapons bays should have a compact missile with folding fins. This condition would mean the F-22 could not carry standard missiles. An anticipated problem of internal missiles with folding fins is they may not be capable of withstanding stresses when carried externally on current fighters. The latter is not acceptable in this modern age in military hardware. This is because of the ability for almost all Air Force weapons to be used on its current fleet of fighter aircraft. The ability for Air to Air and Air to ground weapons to be carried on multiple aircraft cuts down on costs and maintenance support.

The Aim 120C is a compromise. Reason being, the tails and wings of the missile have been reduced in size with the intent for the missile to fit better into internal bays. Best of all, there are no performance compromises with the reduction. In addition, the USAF has announced the AIM-120C will become the standard version for all of its fighters. The Aim-120C's will be propelled off of the missile rack inside of the weapons bays by pneumatic and/or hydraulic ejectors.


 
AIM 9

The F-22's side weapons bays (one on each side) will initially hold one Aim 9 Sidewinder missile. The Sidewinder is a heat seeking IR guided missile effective at short range. In the future however, the Aim-9x IR guided missile will be introduced which will have small tail surfaces unlike previous versions. Most likely, the F-22 will be capable of carrying two Aim-9x's per side. The Aim 9 Sidewinder will be extended on a trapeze mounted launcher before the launch. This is to allow the Aim 9's IR seeker to effectively acquire the target or "sniff" it.


M61A2 cannon

The F-22 will come equipped with an internal cannon. Lockheed Martin will install a M61A2 cannon, which is an improved version of the original M61. A new feature includes longer, composite-wound bullets. The M61A2 will be mounted just above the right wing root. To preserve the F-22's stealthy characteristics, an inward opening door will cover the muzzle until the weapon is fired.  It is capable of firing 100 rounds per second, carrying 480 rounds in all.

 
JDAM

In 1994, the USAF asked Lockheed Martin to develop an air to surface capability for the F-22. Provisions were later made to the lower weapons bays to accommodate one 1,000 pound GBU-30/32 Joint Direct Attack Munition (JDAM) per side. A simple GPS (Global Positioning System)/inertial system will guide the weapon to its target. Eventually later versions will have increased precision attack capability by including a programmable radar seeker. The F-22's air-to-surface operations will be carried out courtesy of its onboard synthetic aperture radar (SAR) mode.

In addition to the F-22's internal weapons bays, it will also be capable of carrying stores externally. Four underwing stations will be able to support up to 5,000 pounds. Underwing stores will be fitted to the F-22 when stealth is not critical. External drop tanks up to 600 US gallons can also be fitted onto the stations. This will increase the F-22's endurance and range significantly.


Following explains the systems and arrangements from: http://www.f-22raptor.com/

Arrangement 

The F-22 is capable of carrying existing and planned air-to-air weapons. These include a full complement of medium-range missiles such as the AIM-120A advanced medium range air-to-air missile (AMRAAM) and short-range missiles such as the AIM-9 Sidewinder.


The F-22 has four internal weapons bays for its main armaments. Two at the bottom of the mid-fuselage and two on the air intake sides. Four underwing hardpoints are mainly meant for fuel tanks on ferry flights, but can also carry a weapon load. Below the different weapons configurations are shown:


Air-to-air configuration; 2 AIM-9 [Sidewinder] missiles in the side bays + 6 AIM 120C [AMRAAM] missiles. (or 4 of the older AIM 120A [AMRAAM] missiles, which have longer fins)



Air-to-ground configuration; 2 AIM-9 [Sidewinder] missiles in the side bays + 2 AIM 120C [AMRAAM] missiles + 2 GBU-32 JDAM 450 pounds bombs. (or 2 GBU-30 JDAM 1000 pound bombs and no AMRAAM missiles)
External combat configuration; 2 fueltanks + 4 missiles.

Ferry configuration; 4 external fuel tanks + 8 missilesBelow is picture of the missile ejection system which can be found in the main weapons bay. If the pilot decides to fire a missile, the beapons bay door of the referring missile will open, the mechanism will carry the missile outside the plane, the missile can lock and it is fired. When the missile is away, the ejection system will retract into the weapons bay again and the bay door closes to preserve the fighters stealthyness.



Mission
The F-22 Raptor is the Air Force's newest fighter aircraft. Its combination of stealth, supercruise, maneuverability, and integrated avionics, coupled with improved supportability, represents an exponential leap in warfighting capabilities. The Raptor performs both air-to-air and air-to-ground missions allowing full realization of operational concepts vital to the 21st century Air Force.

The F-22, a critical component of the Global Strike Task Force, is designed to project air dominance, rapidly and at great distances and defeat threats attempting to deny access to our nation's Air Force, Army, Navy and Marine Corps. The F-22 cannot be matched by any known or projected fighter aircraft.

Features
A combination of sensor capability, integrated avionics, situational awareness, and weapons provides first-kill opportunity against threats. The F-22 possesses a sophisticated sensor suite allowing the pilot to track, identify, shoot and kill air-to-air threats before being detected. Significant advances in cockpit design and sensor fusion improve the pilot's situational awareness. In the air-to-air configuration the Raptor carries six AIM-120 AMRAAMs and two AIM-9 Sidewinders.

The F-22 has a significant capability to attack surface targets. In the air-to-ground configuration the aircraft can carry two 1,000-pound GBU-32 Joint Direct Attack Munitions internally and will use on-board avionics for navigation and weapons delivery support. In the future air-to-ground capability will be enhanced with the addition of an upgraded radar and up to eight small diameter bombs. The Raptor will also carry two AIM-120s and two AIM-9s in the air-to-ground configuration.

Advances in low-observable technologies provide significantly improved survivability and lethality against air-to-air and surface-to-air threats. The F-22 brings stealth into the day, enabling it not only to protect itself but other assets.

The F-22 engines produce more thrust than any current fighter engine. The combination of sleek aerodynamic design and increased thrust allows the F-22 to cruise at supersonic airspeeds (greater than 1.5 Mach) without using afterburner -- a characteristic known as supercruise. Supercruise greatly expands the F-22 's operating envelope in both speed and range over current fighters, which must use fuel-consuming afterburner to operate at supersonic speeds.

The sophisticated F-22 aerodesign, advanced flight controls, thrust vectoring, and high thrust-to-weight ratio provide the capability to outmaneuver all current and projected aircraft. The F-22 design has been extensively tested and refined aerodynamically during the development process.

The F-22's characteristics provide a synergistic effect ensuring F-22A lethality against all advanced air threats. The combination of stealth, integrated avionics and supercruise drastically shrinks surface-to-air missile engagement envelopes and minimizes enemy capabilities to track and engage the F-22. The combination of reduced observability and supercruise accentuates the advantage of surprise in a tactical environment.

The F-22 will have better reliability and maintainability than any fighter aircraft in history.  Increased F-22 reliability and maintainability pays off in less manpower required to fix the aircraft and the ability to operate more efficiently.

Background
The Advanced Tactical Fighter entered the Demonstration and Validation phase in 1986. The prototype aircraft (YF-22 and YF-23) both completed their first flights in late 1990. Ultimately the YF-22 was selected as best of the two and the engineering and manufacturing development effort began in 1991 with development contracts to Lockheed/Boeing (airframe) and Pratt & Whitney (engines). EMD included extensive subsystem and system testing as well as flight testing with nine aircraft at Edwards Air Force Base, Calif. The first EMD flight was in 1997 and at the completion of its flight test life this aircraft was used for live-fire testing.

The program received approval to enter low rate initial production in 2001. Initial operational and test evaluation by the Air Force Operational Test and Evaluation Center was successfully completed in 2004. Based on maturity of design and other factors the program received approval for full rate production in 2005. Air Education and Training Command, Air Combat Command and Pacific Air Forces are the primary Air Force organizations flying the F-22.  The aircraft designation was the F/A-22 for a short time before being renamed F-22A in December 2005.
