3.0 Main fuselage components
The F/A-22 fuselage is built in 4 major parts which are manufactured by different companies. The illustration below shows who is taking care of what component.

:: who takes care of what regarding manufacturing the F/A-22 ::


- Lockheed Martin in Marietta takes care of constructing the Forward fuselage, the fins, flaps, ailerons and front-end flaps and for mating the three major fuselage components.

- Lockheed Martin in Fort Worth takes care of building the Mid Fuselage. This is the largest and most complex of the F/A-22 assemblies. It is approximately 17 feet long, 15 feet wide, and six feet high and weighs about 8,500 pounds as shipped. Most of the wiring and tubing for the aircraft subsystems is integrated here.

- Boeing takes care of building the Aft fuselage, main wings, power supplies, auxiliary power units, auxiliary power generation systems, airframe-mounted accessory drives and the fire-protection system.

Boeing also takes care of the aircraft's environmental control system and fuel, electrical, hydraulic and engine subsystems.

A completed aft fuselage weighs 5,000 pounds and measures 19 feet long by 12 feet wide.
  :: The aft fuselage being handled in the BOEING plant ::
The aft fuselage is 67 percent titanium, 22 percent aluminum and 11 percent composite by weight.

- Pratt & Whitney delivers the 2 F119 jet engines that power the F/A-22. Click here for the F119 engine specifications, thrustvectoring and other information about jetengines.



4.0 Inner Structure
Most of the structural loads are absorbed by 5 titanium bulkheads in the middle section of the F/A-22. The largest one has a dimension of 16 ft by 6 feet, weighing 149 kg (329 lb).

:: The largest bulkhead  (boom) right after birth. The space on the top-right position is neccessary to give room for the F/A-22's gun ::

The welded booms of the aft fuselage are extremely weight-efficient and reduce the use of traditional fasteners by approximately 75 percent.


5.0 Wings
The wings of the F/A-22 are the so-called large area clipped delta type, being efficient at high speed. The wings have large leading edge flaps, which make the aircraft capable of also being efficient at low speeds and to enable it to reach extreme Angles of Attack (AOT) of over 60 degrees.

The F/A-22's wings, which function as fuel tanks, have undergone a series of pressure tests to ensure they are leak proof. Boeing applied several advanced manufacturing processes to build the wings, which are made primarily of titanium and composites.


5.1 Fins
The fins are located at the back end of the plane and when viewed from the side, the large fin blocks the heat radiation of the aircrafts engine exhausts as well as any radar search scan.

The surfaces and edges are positioned on the F/A-22 in groups. The horizontal aileron edges are aligned parallel with the main wings, as well as the fins which are angled the same as the sloped body sides of the plane (looked at from the front). The vertical fins contain besides the steering rudders, several antenna's and sensors, used by the avionics for target acquisition as well as communications.


6.0 Weapons bays
The F/A-22 is armed with 6 AIM-120C missiles, or 2 GBU-30 1000 lb JDAM bombs in the ventral bays. These are located on the bottom of the plane. 2 AIM-9 Sidewinder missiles are stored internally in the sides of the air intake ducts.


The weapons bays are covered by doors, which are closed during normal flight. When an AIM-9 missile is fired, the door opens, an ejection mechanism is positioning the missiles outside the plane and the missiles is fired. The AIM-120C missile just drops from the plane and ignites its rocket when it is on a safe distance from the plane. After firing a missile, the doors close again to preserve stealth.


7.0 Landing Gear
The landing gear is a Menasco retractable tricycle type, stressed for no-flare landings of up to 3.05m/s downward speed. The nosewheel tyre measures 23.5 x 7.5-10 and the 2 mainwheel tyres measure 37 x 11.5-18.


8.0 Air inlets
The air intakes are located to the sides of the narrower part of the fighter's nose. The inner tubes, where gas and liquid flow, curves inward then upward, to cover the front part of the engine. Looking at the F/A-22 from the front, the face of the engine is completely invisible dramatically decreasing the chance of radar detection.


9.0 Cockpit
The F-22's cockpit is one of the very first "all-glass" cockpits for tactical fighters – there are no traditional round dial, standby or dedicated gauges. It accommodates the largest range of pilots (the central 99 percent of the Air Force pilot population) of any tactical aircraft. It is the first baseline "night vision goggle" compatible cockpit, and it has designed-in growth capability for helmet-mounted systems. The canopy is the largest piece of polycarbonate formed in the world with the largest Zone 1 (highest quality) optics for compatibility with helmet-mounted systems. While functionality is critical, the F-22's cockpit design also ensures pilot safety with an improved version of the proven ACES II ejection seat and a new pilot personal equipment and life support ensemble.


The F-22's cockpit represents a revolution over current "pilot offices", as it is designed to let the pilot operate as a tactician, not a sensor operator. Humans are good differentiators, but they are poor integrators. The F-22 cockpit lets the pilot do what humans do best, and it fully utilizes the power of the computer to do what it does best.
