The U.S. Air Forces new F-22 fighter is expensive (over $200 million
each) partly because of its extensive array of electronic sensors. The air
force, looking to get this expensive bird some work, considered sending a few
to Iraq. There, the F-22 would use its sensors to detect enemy activity on the
ground. Problem is, the F-22 sensors are tuned to detect much fainter signals
present during a high altitude air-to-air combat. When tested closer to the
ground, the F-22 sensors were overloaded. The fix for that problem was to
re-tune the F-22 sensors, and the spiffy new F-22 sensors and hardware are
amazingly reconfigurable. But at this point someone pointed out that, it was a
lot cheaper to buy more Predators, especially the larger Predator B (which cost
about less than five percent of what the air force is paying for F-22s). The
Predator is cheaper to operate, can stay in the air longer, and can be easily
fitted with less expensive sensors, better suited to the noisy ground level
environment. The big bottleneck with Predators is training crews fast enough.
Since Predators stay in the air for 24 hours or more per sortie, you need
several shifts of crews. New operator stations (using multiple flat screen
displays and display software based on computer game technology) now enable one
operator to handle two Predators simultaneously, but the new stations were
supposed to make it possible for one pilot to run up to four UAVs at once.
Didn't work out that way, although improvements in the operator station
software, and the availability of more experienced UAV jockeys, might fix
that.
In
the meantime, F-22s are being sent to the Pacific. There, as air superiority
fighters, they pose a very real threat to the Chinese and North Korean air
forces.
