Specifications
of F-22 (F/A-22) Following information and some graphics from F22 Virtual Resource
The F22 Raptor’s airframe is comprised mainly of four (4) large “chunks”, or pieces that are produced by separate companies (see illustration below for part and manufacturer).

*The engines (PW-F119-100) are delivered and
manufactured by Pratt and Whitney *The Aft Fuselage, main wing structures, power
generation units, fire protection system, and other various parts, mostly found
in the main fuselage. Boeing also manages many of the subsystems dealing with
fuel, electrical components, and engine operation. *Lockheed Marietta produces and manages the
fins, flaps, ailerons, production of the forward fuselage, and joining the large
chunks of the aircraft together. *Lockheed Ft. Worth manages and oversees the
production and assembly of the main fuselage, or the mid area of it. This job is
possibly the most difficult of all, because of the aircraft’s size, and the
fact that most of the wiring, tubing, and systems run through this portion of
the aircraft.
"The structural loads of the F-22 are mostly absorbed by 5 titanium bulkheads." from F22Virtual Resource (No longer On-line). The "fins" of the aircraft are divided into two types: the horizontal (which control vertical movement) and the vertical (which control the horizontal movement). The horizontal fins (located at the rear of the aircraft) not only provide the plane with extra maneuverability etc... , but also act as a heat shield for the exhaust of the engines, so the thermal trace of the F22 is at a minimum. The vert. fins are angled in the similar fashion of the F-22's body, to help reduce its radar signal. These also contain many internal antennas inside the body of the fin itself, as a way to conceal them and help maintain the stealth abilities of the aircraft.
