The Tornado Aircraft (shown below) entered service with the RAF in the mid 1980s as a result of a multi-national development programme. Production ceased in 1998. The F3 variant replaced the Phantom. It was the first RAF swing wing aircraft and had a top speed of Mach . It was armed with four Skyflash radar-guided missiles and four Sidewinder infra-red homing air-to-air missiles providing a fire-and-forget capability. Some 100 RAF F3 Tornadoes have been upgraded to carry the recently developed Advanced Medium Range Air-to-Air Missiles (AMRAAM) a radar guided fire-and-forget air-to-air missile.
