The most capable air-superiority fighter in the world when it entered service in 1976 with excellent radar and avionics for BVR (Beyond Visual Range) engagements and surprising agility for dogfighting. The F-15 has since been developed into an excellent multi-role aircraft. By 2010 the F-22 will replace the F-15 in the air superiority role, although the "Strike Eagle" variant will retain its frontline role.%n
