And the new boy makes good! Right on the money, my friend; the Ki-15 it is. The Ki-15 was remarkably fast for it's time; especially considering the engine and fixed undercarriage. You're up to ask the next question. Thanks; Ernie P.
Question: What warbird do I describe?
Clues:
(1). Began life as a mail plane.
(2) A fast mailplane.
(3) Was developed into a reconnaissance aircraft and light bomber.
(4) A single engine, low wing monoplane.
(5) A crew of two.
(6) Served with both the navy and army.
(7) First flew in 1936; first entered service in 1937.
(8) Set a world speed record over distance in 1937.
(9) Lightweight for its size.
(10) Speed was impressive; especially considering (A) The relatively anemic engine; and
(11) (B) the fixed and spatted undercarriage.
(12) The second plane built was purchased by a newspaper.
Answer: The Mitsubishi Ki-15; “Babs”.
The Mitsubishi Ki-15 (九七式司令部偵察機, Kyunana-shiki sireibu teisatsuki?) was a Japanese reconnaissance aircraft and a light attack bomber of the Second Sino-Japanese War and Pacific War. It began as a fast civilian mail plane. It was a single-engine, low-wing, cantilever monoplane with a fixed tailwheel undercarriage; it carried a crew of two. It served with both the Imperial Japanese Army and Navy (as the C5M). During World War II it was nicknamed "Babs" by the Allies.
The Ki-15 was designed by the Mitsubishi corporation to meet an Imperial Japanese Army Air Force requirement of 1935 for a two-seat, high-speed reconnaissance aircraft. The resulting aircraft was a low-wing cantilever monoplane with a fixed, spatted undercarriage, similar to other all-metal stressed-skin monoplanes developed elsewhere in 1930s, such as the Heinkel He 70 and the Northrop Alpha. Power was by a single Nakajima Ha-8 radial engine, giving 560 kW (750 hp) at 4,000 m (13,120 ft). The first prototype flew in May 1936, with testing proving successful, the aircraft meeting all performance requirements, reaching a speed of 481 km/h (299 mph) and showing good handling characteristics.
Service testing was completed without difficulty and the type was ordered into production under the official designation Army Type 97 Command Reconnaissance Plane Model 1 In May 1937, a year after the first flight, delivery of the first of 437 production aircraft to the army began.
Despite the relatively weak engine and fixed undercarriage, the Ki-15 was remarkably fast. During the initial flight testing, the Asahi newspaper Asahi Shimbun obtained permission to purchase the second prototype. The aircraft was given the designation Karigane (Wild Goose), flying on 19 March 1937, being named Kamikaze and registered as J-BAAI. It was the first Japanese-built airplane to fly to Europe and caused a sensation in 1937 by making the flight between Tokyo and London, for the Coronation of King George VI, between 6 April 1937 and 9 April 1937 in a flight time of 51 hours, 17 minutes and 23 seconds, a world record at the time. Following the success of the Japan-England flight, a small number of Ki-15s were sold to civil customers. One of the early production aircraft was named "Asakaze" (J-BAAL) and was also used by the "Asahi Shimbun"; others were used by various civilian operators as mail planes.
The Ki-15-I was almost immediately placed into operational service at the beginning of the war with China in 1937. The aircraft proved useful in the early period of the Second Sino-Japanese War and performed missions deep into Chinese strategic rear areas, as far as reaching Lanzhou. Its high speed gave it a distinct advantage until the Chinese Air Force acquired Soviet Polikarpov I-16 fighters. This aircraft was used for level bombing, close support and photo reconnaissance before being eventually replaced by the Mitsubishi Ki-30.
Plans were already in hand to improve the Ki-15-I, and in September 1939 the Ki-15-II was put into production with the 671 kW (900 hp) Mitsubishi Ha-26-1; the smaller diameter of this both reduced drag and overcame one of the major shortcomings of the initial version: poor forward field of view past the large-diameter of the initial Nakajima Kotobuki engine. The improved version entered production in September 1939 as the Ki-15-II.
The Japanese Navy, impressed by the performance of this aircraft, ordered 20 examples of the Ki-15-II under the designation “Navy Type 98 Reconnaissance Plane Model 1," or Mitsubishi designation C5M1, even before the Army. The Navy acquired subsequently 30 C5M2 aircraft which had an even more powerful 708 kW (949 hp) Nakajima Sakae 12 engine. They were used for reconnaissance duties. In a subsequent upgrade, the army also experimented with an even more powerful engine with 783 kW (1,050 hp) Mitsubishi 102 radial in the Ki-15-III which did not enter production.
When production ended, approximately 500 examples of all versions of the Ki-15 had been built, the majority in front-line service when the Pacific War began. By 1943, the Ki-15 had been relegated to second-line roles, but numbers were expended in kamikaze attacks in the closing stages of World War II.
