Roden 632 O-2A Skymaster U.S. Navy Service 1:32

In the early 1960s, the Cessna aircraft company built a small commercial aircraft, the Model 337. Compared with similar aircraft of the same class, it had an unusual layout: a tractor engine in front, and a pusher in the rear. Instead of the classic fuselage layout, two booms extended backwards from the wing, which were connected by the horizontal tail assembly. The aircraft could carry two crew members, and four passengers or up to 450 kg of payload. It was quite successful commercially, but Cessna also hoped to find an outlet in a military role. In 1967 a military version of the machine appeared, the O-2A Skymaster.

With the start of the Vietnam War, the US Air Force began to actively employ light aircraft as scouts, for fire direction or lightweight communications. One of the most widely used was the O-1 Bird Dog, but it was not always able to perform certain military tasks, such as controlling targeting for other planes. The O-2 was more suited to this type of task and, therefore, was soon involved in missions of this kind in the Vietnam conflict.

Also, the O-2 could be used as a light strike plane, like its predecessor the O-1. For this, pods of unguided rockets and other light weapons could be hung under the wing of the aircraft. Some machines, designated O-2B, carried out 'psychological warfare missions — they were fitted with speakerphones broadcasting calls to the population to stop the war, but this exercise was not successful.

Another important application for the O-2 was the rescue of pilots whose planes had been downed in an area of operations. The O-2 could take off from the shortest airstrips and land in the most unsuitable places for this purpose. Many US Air Force pilots had this machine to thank for their rescue.
