In 1938, when the [[Mitsubishi Ki-21|Ki-21]] [[heavy bomber]] began to enter service with the [[Imperial Japanese Army]], its capability attracted the attention of the [[Imperial Japanese Airways]]. In consequence a civil version was developed and this, generally similar to the Ki-21-I and retaining its powerplant of two 708 kW (950 hp) Nakajima Ha-5 KAI [[radial engine]]s, differed primarily by having the same wings transferred from a mid to low-wing configuration and the incorporation of a new [[fuselage]] to provide accommodation for up to 11 passengers. This transport version appealed also the navy, and following the flight of a [[prototype]] in August 1940 and subsequent testing, the type was ordered into production for both civil and military use.<ref>{{Harvnb|Francillon|1979|pp=182–183.}}</ref> |

This initial production '''Ki-57-I''' had the civil and military designations of '''MC-20-I''' and '''Army Type 100 Transport Model 1''', respectively. A total of 100 production Ki-57-Is had been built by early 1942, and small numbers of them were transferred for use by the Japanese navy in a transport role, then becoming redesignated '''L4M1'''. After the last of the Ki-57s had been delivered production was switched to an improved '''Ki-57-II''', which introduced more powerful 805 kW (1,080 hp) Mitsubishi Ha-l02 14-cylinder radial engines installed in redesigned nacelles and, at the same time, incorporated a number of detail refinements and minor equipment changes. Civil and military designations of this version were the '''MC-20-II''' and '''Army Type 100 Transport Model 2''', respectively. Only 406 were built before production ended in January 1945. Both versions were covered by the Allied [[World War II Allied names for Japanese aircraft|reporting name]] "'''Topsy'''".<ref>{{Harvnb|Francillon|1979|pp=183–184.}}</ref> |

The Mitsubishi Ki-57 was a Japanese passenger transport aircraft, developed from the Ki-21 bomber, during the early 1940s.
Development
[edit]In 1938, when the Ki-21 heavy bomber began to enter service with the Imperial Japanese Army, its capability attracted the attention of the Imperial Japanese Airways. In consequence, a civil version was developed and this, generally similar to the Ki-21-I and retaining its powerplant of two 708 kW (950 hp) Nakajima Ha-5 KAI radial engines, differed primarily by having the same wings transferred from a mid- to low-wing configuration and the incorporation of a new fuselage to provide accommodation for up to 11 passengers. This transport version appealed also to the navy, and following the flight of a prototype in August 1940 and subsequent testing, the type was ordered into production for both civil and military use.[1]
This initial production Ki-57-I had the civil and military designations of MC-20-I and Army Type 100 Transport Model 1, respectively. A total of 100 production Ki-57-Is had been built by early 1942, and small numbers of them were transferred for use by the Japanese navy in a transport role, then becoming redesignated L4M1. After the last of the Ki-57s had been delivered production was switched to an improved Ki-57-II, which introduced more powerful 805 kW (1,080 hp) Mitsubishi Ha-102 14-cylinder radial engines installed in redesigned nacelles and, at the same time, incorporated a number of detail refinements and minor equipment changes. Civil and military designations of this version were the MC-20-II and Army Type 100 Transport Model 2, respectively. Only 406 were built before production ended in January 1945. Both versions were covered by the Allied reporting name "Topsy".[2]
Variants
[edit]- Ki-57-I Army Type 100 Transport Model 1: Powered by two 708 kW (950 hp) Nakajima Ha-5 KAI radial engines and a redesigned fuselage to accommodate 11 passengers. About 100 aircraft of this type were built including the civil version.
- MC-20-I: Same as above but built for civil use with Imperial Japanese Airways (Dai Nippon Koku KK).
- Ki-57-II Army Type 100 Transport Model 2:Powered by two 805 kW (1,080 hp) Mitsubishi Ha-102 Zuisei 14-cylinder radial engines installed in redesigned nacelles. Minor equipment and detail refinements were also incorporated. 306 aircraft of this type were produced before the end of production in January 1945.
- MC-20-II: Same as above but built for civil use with Imperial Japanese Airways (Dai Nippon Koku KK).
- L4M1: A small number of Ki-57-Is were transferred for test by the Japanese navy as transports and were redesignated L4M1.
