I thought the answer to that question was simple: the F-22 is a pure fighter, and there’s no crying need for pure fighters to enforce the no-fly zone that can’t be met with older aircraft. Apparently, it’s a bit more complicated:
Conspicuously absent in the skies over Libya is the new American F-22. Despite modifying the F-22 to operate as a fighter-bomber, the F-22 was uniquely unsuited to operate as part of the international force assigned to stop Libya from attacking its own people. That job requires aircraft that can carry lots of smart bombs. Defeating the Libyan Air Force was not a major chore, and was easily handled by less capable (and cheaper to operate) air superiority fighters. Another problem was communications. The F-22 is not equipped to operate as part of an international aerial armada. The F-22 is a stealthy lone-wolf. Most of the time, the F-22 does not use its radio. To communicate with other F-22s, a special, short-range system is used. The F-22 does not have the full suite of communications equipment most NATO warplanes carry.

The 36 ton F-22 has internal bomb bays, like the F-117, to enhance stealthiness. Thus it can carry two half ton smart bombs, or eight 250 pound SDBs (ground penetrating Small Diameter Bombs) internally, in addition to a pair of air-to-air missiles. However, the F-22 is not yet modified to carry the SDB. The internal bays were originally designed to carry six air-to-air missiles, not bombs. Using the external hard points, which makes the aircraft more visible on radar, an F-22 can carry about four tons of bombs and missiles.
The F-22 has the most advanced radar and electronic warfare gear of any jet fighter. When you include the cost of research and development, each F-22 ends up costing nearly $400 million. But for pilots in certain types of combat, it’s money well spent. But not for what was needed over Libya, where most non-stealthy fighters can carry four or more tons of bombs and missiles.
