General Dynamics EF-111 Raven

The General Dynamics/Grumman EF-111A Raven was an electronic warfare aircraft designed to replace the B-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 until 1996.

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 EA-6B Prowlers, but was reluctant to adopt a Navy aircraft. The EF-111 entered service in 1983 and served until it was retired in 1998. Afterwards, the Air Force began depending on Navy and Marine Corps EA-6Bs (and later EA-18Gs) for electronic warfare support.
