The F-22 is the premier air superiority fighter. No other country has anything like it. A few squadrons would be sufficient for the U.S. to maintain air superiority in any theather of war. The F-15 the current air superiority fighter is still a great aircraft and in the hands of our great pilots is still invincible, but this jet has been in service since the early 70's. Many nations have comparable aircrafts to the F-15, such as the Russian SU-27 which has many variations including a potentially carrier capable one in the SU-37. The Chinese have their own copies of the Russian aircraft as wel as several indigenous versions that they can export to smaller nations.
The point is that without the F-22 the U.S. runs a real chance of having it's air dominace challenged in the coming years.
Please call your congress person and ask them to keep the F-22 program as well as the new f-35 engine upgrade going to endure our Soldiers, Airmen and Marines can keep kicking @#$#@ and keepoing us safe.
