Boeing began major assembly of the aft fuselage for the world's first F-22 air dominance fighter on June 17, 1996.

The aft fuselage also contains all or part of the aircraft's environmental control system and fuel, electrical, hydraulic and engine subsystems.

The aft fuselage is 67 percent titanium, 22 percent aluminum and 11 percent composite by weight.

The aft fuselage was designed entirely on the three-dimensional computer-aided design (CAD) system called CATIA.

Approximately 25 percent (by weight) of the aft fuselage comprises large electron-beam welded titanium subassemblies called booms.

Lockheed Martin in Fort Worth, Texas, is responsible for building the mid-fuselage section of the F-22.

Lockheed Martin is responsible for overall F-22 program management.

By weight, the Boeing-built portion of the wing is 42 percent titanium, 35 percent composite and 23 percent aluminum, steel and other materials in the form of fasteners, clips and other miscellaneous parts.

The aft fuselage houses the two Pratt & Whitney-built F119 engines that power the F-22.

A completed aft fuselage weighs 5,000 pounds.

A completed aft fuselage measures 19 feet long by 12 feet wide.

The aft fuselage is designed to withstand supersonic speeds for extended periods of time and extremely "high-g" maneuvers.

The largest of these booms, the forward boom, spans more than 10 feet and weighs approximately 650 pounds.

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

Lockheed Martin in Marietta, Ga., is responsible for the forward-fuselage section and for mating the three major fuselage components.

Boeing began assembly of the left-hand wing for the world's first F-22 air dominance fighter on January 17, 1996.

Each wing weighs about 2,000 pounds.
