The Grumman A-6 Intruder was known for being an unattractive attack bomber. However, it was noted for excelling at its intended missions and was a versatile bomber. The naval aircraft first flew in 1960 and was superseded by the F-14 Tomcat and the F/A-18 Hornet family. Its Cold War legacy is arguably overshadowed by its remarkable contemporary Harrier jump jet. The Harrier has continued to be used by the Marines, and the last are expected to retire in the coming years.
