HISTORY: The Cessna 172 is by far and away the most successful light aircraft built, and so it is not surprising that a significant portion of the nearly 42,000 built found their way into military service.
The 172 began life as a tricycle undercarriage development of the four place Cessna 170, the aircraft that also formed the basis of the 0-1 Bird Dog (described separately). The prototype 170 flew in September 1947, the prototype 172 in November 1955. The type was a success almost instantly, and through to 1986 the 172 was built in successively improved variants. An improved 172, aimed principally at civil customers, is due to enter production in 1996.
US military interest resulted in the July 1964 US Air Force order for Cessna 172Fs for pilot flight screening performed by civil firms under contract, designated the T-41 A Mescalero. These aircraft differ little from the civil 172F, and production took place between 1964 and 1967. The US Army also ordered 172s for pilot training, its T-41Bs based on the R172E with a 155kW (210hp) Continental IO-360 driving a constant speed prop. The USAF's T-41 C was similar to the T-41 B except for its fixed pitch propeller, and 52 were built for the USAF Academy. The T-41D, based on the T-41 C but with a 28 volt electrical system, was procured for a number of countries under the US's Military Assistance Program (MAP). 311 T-41 Ds were built between 1968 and 1978. In 1995 50 T-41 s remained in service with the US Air Force, although replacement with T-3 Fireflies was near completion.
Apart from 172s built as T-41s, several other countries procured civil 172s direct from Cessna, or from Reims-Cessna in France, which built several thousand FR172s under licence. In all, over 30 countries have operated military 172s or T-41 s.
Apart from basic pilot training, the 172 is also widely used for a number of secondary duties such as observation, liaison and border patrol.
