General Dynamics–Grumman EF-111A Raven

The General Dynamics–Grumman EF-111A Raven is a retired electronic-warfare aircraft that was designed and produced by the American aerospace manufacturers General Dynamics and Grumman. It was operated exclusively by the United States Air Force (USAF); its crews and maintainers often called it the "Spark-Vark", a play on the F-111's "Aardvark" nickname.
