General Dynamics / Grumman EF-111A Raven

EF-111A

The General Dynamics–Grumman EF-111A Raven is an electronic-warfare aircraft designed to replace the EB-66 Destroyer in the United States Air Force.

Its crews and maintainers often called it the “Spark-Vark”, a play on the F-111’s “Aardvark” nickname.

The USAF contracted with Grumman in 1974 to convert some existing General Dynamics F-111As into electronic warfare/electronic countermeasures (ECM) aircraft.

The USAF had considered the Navy / Marine Corps Grumman EA-6B Prowler, but desired a penetrating aircraft with supersonic speed.

The EF-111 entered service in 1983 and served until its retirement in 1998.

Electronic warfare conversion of the F-111A, 42 conversions including two prototypes.
