Shipborne Reconnaissance Aircraft
C6N Saiun. 彩雲 Sayyun (Rainbow Cloud). In the course of the conduct of hostilities, when the American aviation significantly increased the effectiveness of its actions, there was an urgent need to adopt a specialized long-range high-speed reconnaissance aircraft. Improvised scouts from conventional carrier-based torpedo bombers have already ceased to satisfy the Japanese command.
In the spring of 1942, the design of the aircraft, which received the military designation C6N1, was headed by Yasuo Fukuda and Yoshizo Yamamoto. A new 18-cylinder Homare-21 small-diameter radial engine with a capacity of 1820 hp was chosen as the power plant. with., during the design, special attention was paid to the purity of aerodynamic forms. On May 15, 1943, the first C6N1 prototype took off. The aircraft showed good flight characteristics, but the engine turned out to be unreliable, moreover, it did not develop the required power at high altitudes.
A total of 19 aircraft were built from March 1943 to April 1944, some of them were equipped with a new, more powerful Homare-21 engine with a three-bladed propeller shaft instead of a four-bladed one. Finally, in the spring of 1944, the aircraft was sent to mass production with a new 1900 hp engine. from.
The C6N1 reconnaissance aircraft turned out to be one of the best aircraft in the world in its class. The Allied aircraft received the code designation Mirt.

High speed and long flight range allowed the Sayuns to avoid encounters with most enemy fighters and conduct reconnaissance in remote areas where Japanese aircraft were not expected to appear.
