The Grumman A-6 Intruder was an American, twin jet-engine, mid-wing attack aircraft built by Grumman Aerospace. In service with the U.S. Navy and U.S. Marine Corps between 1963 and 1997, the Intruder was designed as an all-weather medium attack aircraft to replace the piston-engined A-1 Skyraider. As the A-6E was slated for retirement, its precision strike mission was taken over by the F-14 Tomcat equipped with LANTIRN pod. A specialized electronic warfare derivative, the EA-6B Prowler, remains in service as of 2011.
