F-5A Freedom Fighter / F-5E Tiger II, Northrop


F-5A Freedom Fighter / F-5E Tiger II

The F-5 was developed as a cheap 'export fighter' for military assistance programs. It was a small jet fighter with short-span wings, twin-engined and optimized for easy maintenance. The F-5 was never used on a large scale by the USAF, but because of characteristics similar to the MiG-21, the F-5 was used as 'agressor' aircraft. The USAF did also use the closely related T-38 supersonic trainer. While the F-5A (799 built) was a very basic aircraft with minimal equipment, the F-5E Tiger II (1166 built) was much more capable. Finally, the much-modified, single-engined F-5G was renamed F-20. At least 28 countries used the F-5.

F-5A Freedom Fighter

The F-5 is a supersonic fighter combining low cost, ease of maintenance, and great versatility. More than 2,000 F-5 aircraft have been procured by the USAF for use by allied nations. The F-5, which resembles the USAF Northrop T-38 trainer, is suitable for various types of ground-support and aerial intercept missions, including those which would have to be conducted from sod fields in combat areas.
The F-5 first flew on July 30, 1959 and deliveries to the Tactical Air Command for instructing foreign pilots began in April 1964. Pilots from Iran and South Korea were the first to be trained in the F-5, followed by pilots from Norway, Greece, Taiwan, Spain, and other Free World nations which have adopted the F-5. A two place combat trainer version, the F-5B, first flew in February 1964. In 1966-67, a USAF squadron of F-5s flew combat missions in Southeast Asia for operational evaluation purposes.

F-5E Tiger II

The F-5E "Tiger II" was a greatly improved version of the earlier F-5A "Freedom Fighter". Redesigned as a highly maneuverable, lightweight and inexpensive air superiority fighter, the -E featured an air-to-air fire control radar system and a lead computing gunsight. More powerful J85 engines required the fuselage to be both widened and lengthened. The forward wing root was redesigned to give the "Tiger II" wing its characteristic triple delta shape.
The first flight of the F-5E was on 11 August 1972. The first USAF unit to receive the aircraft was the 425th TFS at Williams AFB, Arizona responsible for training foreign pilots in the F-5 aircraft. The most well known use of the "Tiger II" was as an aggressor aircraft at the USAF Fighter Weapons School, Nellis AFB Nevada. The aggressor pilots of the 64th Fighter Weapons Squadron were trained in Soviet tactics and used the -Es to simulate MiG-21s for training USAF pilots in aerial combat skills. Eventually, aggressor squadrons were formed at RAF Alconbury, U.K. and Clark AB, PI for training USAF pilots stationed overseas along with pilots of friendly foreign nations.

Iranian 'Saegheh' (Thunder)

Iranian Saegheh / Thunder In September 2006, Iran announced the development of a domestically manufactured war plane named "Saegheh" (Thunder), which it described as similar but superior to the American F-18 fighter jet.

Iran unveiled its first locally manufactured fighter plane during large-scale military exercises, state-run television reported. The report said the bomber Saegheh is similar to the American F-18 fighter plane, but "more powerful." It also said the plane was "designed, optimized and improved by Iranian experts." State TV said the Iranian air force had commissioned the Saegheh plane after many test flights in the past year.

After closer inspection it's clear the airframe is 'just' a F-5E with twin-tails added and probably new engines (maybe RD-33's). The plane on top of this picture is a F-5, the plane below it the new 'F-18 like plane'.
