Every last F14 Tomcat that America has in flyable storage is being shredded to prevent spares reaching Iran!
The Grumman F-14 Tomcat is a supersonic, twin-engine, two-seat, variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental program.
The F-14 was the first of the American teen series fighters which were designed incorporating the experience of air combat against MiG fighters during the Vietnam War. As of 2012, the F-14 was only in service with the Islamic Republic of Iran Air Force, having been exported to Iran in 1976, when the U.S. Had amicable diplomatic relations with Iran's government.
In January 2007, the U.S. Department of Defense announced that sales of spare F-14 parts would be suspended over concerns of the parts ending up in Iran. In July 2007, the remaining American F-14s were shredded to ensure that any parts could not be acquired.
In summer of 2010, Iran requested that the United States deliver the 80th F-14 it had purchased in 1974, but delivery was denied after the Islamic Revolution. In October 2010, an Iranian Air Force commander claimed that the country overhauls and optimizes different types of military aircraft, mentioning that Air Force has even installed Iran-made radar systems on the F-14.
