The EF-111A Raven is a variant of the F-111 Aardvark which is specialized for service as a tactical electronic jamming aircraft.
The EF-111A Raven is known affectionately as the “Fat Tail” and the “Spark Vark.”
The Raven had its beginning in the 1970s when the Grumman Company began modifying 42 F-111A aircraft with the addition of the electronic jamming equipment to create the EF-111A aircraft. The modifications consisted of a 16-foot-long narrow canoe-shaped radome on the underside for the fuselage to house the antennae for the high-powered jamming transmitters and a fin-tip pod on the vertical stabilizer to house the receiving antennae and other equipment, including a processor to detect hostile radar emissions. The electronic jamming equipment weighed approximately 8,000 Ibs. As a result of the modifications, the electronic warfare officer, the right seat crewmember, no longer performed flight-related duties but only monitored the aircraft’s electronic jamming equipment.
In 1984, Grumman/General Dynamics Corporation began building additional modification kits for the EF-111A to enable the aircraft to operate in three roles: standoff jamming, close in jamming and penetration/escort.
