The USAF contracted [Vous devez être inscrit et connecté pour voir ce lien] in 1974 to convert some existing [Vous devez être inscrit et connecté pour voir ce lien] into [Vous devez être inscrit et connecté pour voir ce lien]/[Vous devez être inscrit et connecté pour voir ce lien] (ECM) 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 for electronic warfare support.

Design and development
In the late 1960s, the U.S. Air Force sought a replacement for aging [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] aircraft. The Air Force studied the use of Navy [Vous devez être inscrit et connecté pour voir ce lien] during 1967-68.
[Vous devez être inscrit et connecté pour voir ce lien] However, the Air Force desired a penetrating electronic jamming aircraft with supersonic speed.
[Vous devez être inscrit et connecté pour voir ce lien][Vous devez être inscrit et connecté pour voir ce lien] The Air Force decided in 1972 to modify F-111As into electronic warfare aircraft as a cost effective option.[Vous devez être inscrit et connecté pour voir ce lien]

In January 1974 the Air Force awarded electronic warfare study contracts to [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].
[Vous devez être inscrit et connecté pour voir ce lien]
Grumman was selected as the EF-111 prime contractor in December 1974, then was awarded a contract to modify two F-111As into EF-111 prototypes in January 1975.
The first fully equipped model, known then as the "Electric Fox", flew on 10 March 1977, and deliveries to combat units began in 1981.
A total of 42 airframes were converted at a total cost of US$1.5 billion, the last delivered in 1985.

The Raven retained the F-111A's navigation systems, with a revised AN/APQ-160 radar primarily for ground mapping.
The primary feature of the Raven, however, was the Raytheon [Vous devez être inscrit et connecté pour voir ce lien]E jamming system, developed from the Navy's ALQ-99 on the Prowler.
Its primary electronics were installed in the weapons bay, with transmitters fitted in a 16 feet (4.9 m) long ventral "canoe" [Vous devez être inscrit et connecté pour voir ce lien]; the complete installation weighed some 6,000 pounds (2,700 kg).
Receivers were installed in a fin-tip pod, or "football", similar to that of the EA-6B.
The aircraft's electrical and cooling systems had to be extensively upgraded to support this equipment.
The cockpit was also rearranged, with all flight and navigation displays relocated to the pilot's side, and flight controls except throttles being removed from the other seat, where the electronic warfare officer's instrumentation and controls were installed.
