F-22 Design Shows More Than Expected


New performance info released on the premium fighter jet on the planet, the F-22; a selection below.
Ranges of the new lines of AESA radars are classified. But they are estimated at about 90 mi. for the smallest (aimed at the F-16 radar-upgrade market). The F/A-18E/F and F-35 (with radar ranges of 100 mi.) are followed by the F-22 (110-115-mi.). The largest is carried by the upgraded F-15Cs and Es (125 mi.). By comparison, the range for a mechanically scanned, F-15C radar is 56 mi. according to Russian air force intelligence. U.S. aerospace officials agree that an AESA radar "at least doubles" the range over standard military radars.

When coupled with the electronic techniques generator in an aircraft, the radar can project jamming, false targets and other false information into enemy sensors. Ranges for electronic attack equal the AESA radar plus that of the enemy radar. That could allow electronic attack at ranges of 150 mi. or more. The ability to pick out small targets at a long distance also lets AESA-equipped aircraft find and attack cruise missiles, stealth aircraft and small UAVs.
