Mattlott, you make a great point. Can the F-22 or 35 take hits and still keep dishing it out?

<b>F-22 undergoes live fire test</b> Thursday, August 30, 2001

WRIGHT-PATTERSON AFB, Ohio (AFMCNS) The successful F-22 Raptor live fire test here Aug. 22 completed one more objective toward the operational deployment of the Air Forces newest fighter aircraft.
F-22 program officials here said the test evaluated the aircrafts structural design by simulating having an anti-aircraft artillery round hit it in flight. Computer controlled hydraulic jacks pushed against the wings to simulate a maneuvering airplanes flight loads. A battery of jet engines blew high-velocity air across the wing and the fuel tanks were filled with fuel.
Glenn Miller, F-22 System Program Office deputy director, said he was very pleased with the test.
The F-22 performed as we expected, Miller said. We use these tests to confirm the ability of the F-22 to withstand combat-induced damage. Survivable designs mean reduced loss of aircraft and more importantly our pilots in combat.
The test facility looked like a combination of a science laboratory and Hollywood movie set with cameras and banks of lights. High-speed photography captured the results of the high-explosive incendiary round hitting the aircraft.
Test team members viewed in slow motion to see the detailed effects of the exploding round. Testers also collected numerous other measurements to help understand the test results.
With the wings loaded with fuel, flight loads and airflow applied, lights and cameras came on and the round fired and exploded within the wing fuel tank, test officials reported. The explosive bullet generated a shock wave that traveled through the fuel and imparted loads on the wings skin and internal structure.
A portion of the wing skin deformed into the air stream and then ripped off, officials said. The damaged wing remained largely intact due to unique features of the F-22 wing design. This limited structural damage would allow a pilot to fly the airplane home.
Additional tests will be conducted in the next several weeks to determine the damaged wings remaining flight capability, officials added. These tests will apply even higher flight loads.
A joint government and contractor team led by the F-22 SPO at the Aircraft Survivability Research Facility here conducted the test. The test team consisted of members of the 46th Test Wing Detachment, assisted by the Raptor prime contractor, Lockheed Martin and Boeing who designed and built the Raptor wings.
The Raptor has completed several live-fire tests since the being of the F-22 design phase. Prototypes of portions of the airplane were shot with explosive bullets.
These tests provided Lockheed and Boeing designers with data needed to refine usage of new materials and construction techniques. These earlier tests led to several design changes. This test demonstrated the effectiveness of some of these changes.
After completing its flight tests last year, Raptor 4001, the first flight-test aircraft, flew here to prepare for live-fire testing.
The airplane was installed in the Aircraft Survivability Research Facility in April 2000. Since then, the government and contractor team has been preparing the test facility. (Aeronautical Systems Center Public Affairs contributed to this article.)
