The Raptor is still shaping up to be a fine aircraft platform

The United States Air Force (USAF) F-22A Raptor has only been in operational service for a little over a year now, and the advanced fighter aircraft is already shaping up to be quite a formidable weapon in the skies. The F-22 can supercruise (achieve supersonic speeds without afterburner) at Mach 1.58 and has a top speed of Mach 2+ thanks to its twin Pratt & Whitney F119-PW-100 turbofan engines.

Over the past year, F-22s have partaken in a number of simulated "wargames" to display the capabilities of the aircraft. In one two-week excursion in Alaska, designated Northern Edge, the "Blue Air" team which was led by F-22s simply obliterated its "Red Air" threat.

The Red Air threat was composed of a number of previous generation Air Force and Navy aircraft including the F-15, F-16 and F/A-18 Super Hornet. During the exercise, in which more than 40 aircraft littered the skies, the Blue Team achieved a remarkable 241-to-2 kill ratio. It should be noted that the 2 aircraft lost on the Blue Team were F-15C aircraft and not the F-22s.

"They [the Red Air adversaries] couldn’t see us," Tolliver said. "And that’s what makes the F-22 special. I’m out there and I have weapons like an F-15C or an F-16, but ... I’m basically invisible to the other guy’s radar," said Toliver.

The F-22's also scored a 97% mission effective rate during Northern Edge, flying 102 out of 105 assigned sorties. No other new aircraft to enter service into the USAF has been able to achieve such high readiness levels.

Over the past year, the F-22 has had many other success stories. The aircraft has successfully handled alternating air-to-air and air-to-ground operations and have provided additional sensor coverage for trailing friendly aircraft. F-22s have also released JDAMs from an altitude of 50,000 feet while traveling at Mach 1.5 and successfully fired AIM-120C-5 and AIM-9M missiles at live drone aircraft.

Despite all of the successes, there is still room for improvement in the F-22 program. The aircraft's mechanical readiness is now pegged at 70 to 75%, which is slightly lower than the USAF's optimal 75 to 78% rating. Also, pilots are asking for dual-mode satellite/laser guided bombs for the aircraft as well as a helmet-mounted firing system for weapons. Other improvements already in queue include an upgraded radar system and enhanced capabilities in the event of an electronic attack.

RE: Over budget

The F-22 has gone over budget by a factor of four: the Air Force wanted to buy 700, but now will buy fewer than 200.


You just alluded to a major reason that the aircraft is so over budget. It isn't simply an overrun in cost per aircraft. The more you build, the less each one costs. When the Air Force says they want 700, then decides that they only want 200, the cost is going to go up by a lot because you still have to pay the development costs for the aircraft no matter how many you build. I'm not saying this is the only reason, and yes, the plane does cost more than it was supposed to - even if there were still 700 being ordered, but it is pretty safe to say that the cuts in production have a lot to do with the factor of four cost overrun you are talking about.
