General Dynamics F-111 Aardvark

Nicknames: Flying Pig, Whispering Death, Swinger, Switchblade, SparkVark.

F-111 Aardvark

The F-111 first flew in December 1964 under the TFX (tactical fighter, experimental) designation. It was developed to meet a joint service requirement for a long range interceptor and deep-strike interdictor. Entering the US Air Force service in 1967, it saw action in the Vietnam war, where structural defects and problems with the terrain-following radar caused the loss of several aircrafts. Withdrawn for modifications, the F-111 was reintroduced with considerable success in 1972, earning the nickname "Whispering Death" from the Vietcong.

Dubbed Aardvark which is Afrikaans for "Earth Pig" ( because of its long snout), the F-111 fighter-bomber was favored by Tactical Air Command ( TAC ) units for use on long range, deep interdiction attacks against targets within enemy territory. The FB-111A was used by the Strategic Air Command ( SAC ) as a medium bomber (See patch below). The Aardvark has side-by-side seating for the pilot and weapons systems operator. The two crew members sat in a pressurized capsule which served as an emergency escape module. This module was designed to permit safe escape throughout the entire flight and could serve as a survival shelter on the ground or in the sea.  A Pave Tack laser designator system enables pinpoint delivery of FB-111 Patchordnance. The F-111's wings can be changed in flight from a straight to swept-back delta configuration, hence sometimes they are referred to by their nicknames "Swinger" and "Switchblade".

In 1975, the F-111A underwent modifications by Grumman Aerospace resulting in the EF-111A, which was the electronic warfare derivative of the Aardvark, so it was hardly surprising that its crews quickly adopted the unofficial name "Spark Vark" for their mount. When the modifications were completed, the airframes had been totally re-wired, the weapons bay had been modified and the aircraft was outfitted with the AN/ALQ-99E jamming system which jams enemy radar signals and provide a protective electronic shield for attacking aircrafts.

Initial operational capability (IOC) was achieved in November 1983, and the EF-111A was named the "Raven". Prior to the official designation, Grumman referred to the EF-111A as the "Electronic Fox". As mentioned earlier, the EF-111A community commonly referred to it as the "Spark Vark". The Raven has no armament capability and is therefore forced to rely on high-speed evasion in the event of running into fighters.

However, a dwindling US Defence budget and the drive to consolidate forces, led to the decision to withdraw the Raven from service. The last unit to operate the much-loved and highly effective EF-111A Raven was the 429th Electronic Combat Squadron ( ECS ) at Cannon AFB, New Mexico. The official retirement ceremony was hosted by the 27th Fighter Wing at Cannon AFB, over 1 ~ 3 May 1998, with the final deactivation on 19 June. The Ravens now reside among other classic types in the dusty rows of Aerospace Maintenance and Regeneration Center (AMARC) formerly known as Military Aircraft and Storage Disposition Center (MASDC). AMARC is located in the Davis-Monthan AFB way out in the Arizona desert and is the "mecca" for literally thousands of surplus aircrafts.

Another era in aviation history has been drawn to a close with the retirement of the EF-111A Raven from US Service.

F- 111  Aardvark  Variants
F-111 Pre-production variant, first flew in December 1964.
F-111A Production variant.
F-111B Developed for the US Navy, but was cancelled before its production due to severe weight problems.
F-111C Flown mainly by the Royal Australian Air Force.
F-111D Has improved avionics with better navigation, air-to-air delivery systems and newer turbofan engines. The D proved to be maintenance intensive and was retired in late 1992.
F-111E Has modified air intakes to improve the engine performance at speeds above 2.2 Mach. Most F-111Es served with the 20th Fighter Wing RAF Station, Upper Heyford, England to support NATO.
F-111F Last of the production variants. Modified to carry the Pave Tack system in their weapon bays.
F-111G The FB-111As were reworked as F-111Gs, and these served in a training role until 1993.
FB-111A Used by Strategic Air Command (SAC) as a medium bomber, the FB-111A has longer-span wings.
EF-111 Dubbed as the Raven. This model is the modified version of the F-111A and is equipped with the AN/ALQ-99E jamming sub-system.
