Introduction
The Grumman A-6 Intruder was an all-weather medium attack aircraft used by the United States Marine Corp (USMC) and United States Navy (USN). The Intruder was a replacement for the piston driven Douglas A-1 Skyraideer.
When the A-6 was scheduled for replacement, the strike mission was taken over by the Grumman F-14 Tomcat. The first A-6 flight was on 19 April 1960. The USN retired the last active Intruder on 28 February 1997. Grumman Aircraft built 693 A-6 Intruders.
