                                          Mitsubishi  A5M - A6M2 Model 11 / 21

 

19 May 1937: The IJNAF issues preliminary planning documents for the Prototype 12-Shi carrier-

     based fighter, intended as a replacement for the Mitsubishi A5M Type 96 "Claude".

 

7 July 1937: Beginning of the 2nd Sino-Japanese War that ended 9 September 1945. The 1st

     Sino-Japanese War was from 1 August 1894 to 17 April 1895.

 

September 1937: The A5M Type 96 makes its combat debut over China.

    

5 October 1937: The IJNAF issues its final planning requirements for the Prototype 12-Shi 

     Carrier Fighter; A maximum speed of 270 knots (311 mph.) at 4,000 m., A climb to 3,000 m.

     in 3.5 minutes. A range of 1,010 mls. on internal fuel and 1,685 mls. with auxiliary drop

     tank. Maneuverability equal or better than the A5M. A wingspan of no more than 12 meters.

     Armament to be 2 x 20 mm. cannon in the wings and 2 x 7.7 mm. machine guns in the

     upper cowl + carry 2 x 60 kg. bombs. It had to be able to take off in less than 230 ft. into

     a 30 mph. wind. The landing speed of less than 58 knots (67 mph.).

 

17 January 1938: Nakajima leaves the competition ofter a technical review held at the

     Naval Aircraft Establishement at Yokosuka. They felt the requirements were too

     stringent.

 

April 1938: Mitsubishi's design was approved by the Technical Staff.

 

19 March 1939: 1st A6M1 prototype was completed at Mitsubishis Nagoya plant and

     transferred by ox-drawn cart to the Army's training airfield at Kagamigahara. It was

     designed by a team lead by Jiro Horikoshi.

     Engine: Mitsubishi Zuisei 13: 875 hp.

 

1 April 1939: 1st flight of the A6M1 with Mitsubishi's test pilot Katsuzo Shima. A slight

     vibration in flight was noticed.

    

17 April 1939: The two-blade variable pitch propeller of the original A6M1 was

      replaced with a three-blade constant speed unit which ended the vibration

      problem.

 

25 April 1939: The A6M1 prototype attained 265 knots/3,000 m. (305 mph./9,842 ft.).

 

1 May 1939: The Koku Hombu advised Hirokoshi that the IJNAF intended to replace

     the Mitsubishi Zuisei 13 engine with the Nakajima Sakae 12 offering 950 hp. The

     IJNAF designates the two Zuisei-powered prototypes the A6M1 and the Sakae-

     powered model the A6M2.

 

18 October 1939: 1st flight of the 2nd A6M1 prototype.

 

December 1939: The A6M2 prototype began flight trials. Performance and

     maneuverability exceeded all requirements.

 

21 July 1940: Yokosuka Kokuta sent 15 Type 0 fighters to China for operational

     testing by the 12th Kokutai based at Hankow. Armament: 2 x 20 mm./60 rpg

     wing cannon + 2 x 7.7 mm./500 rpg. cowl machine guns.

 

31 July 1940: The IJNAF formally accepted the Type 0 fighter as the Mitsubishi

     A6M2 Type 0 Carrier Fighter Model 11. This was shortened to Zero-Sen.

 

19 August 1940: 1st mission of the 12th Kokutai.

 

13 September 1940: Zero-Sen pilots claim 27 Chinese fighters shot down over

     Chungking in their first combat with Chinese I-15bis and I-16 fighters with

     no losses.

 

Note: By the end of 1940 the 12th Kokutai pilots had claimed 59 fighers destroyed

     in aerial combat plus another 101 destroyed on the ground for the loss of 3

     Zero-Sens to anti-aircraft fire. This is where the legend of the Zero-Sen's

     invincibility began.

 

Note: To allow the Zero-Sen to fit on the carrier elevators better, Mitsubishi

     introduced folding wingtips on the 65th production aircraft. This became the

     A6M2 Model 21.

 

                                        Mitsubishi A6M4 Model 41 / 42

 

1943: Two A6M2s were fitted with experimental turbo-superchargers for high

     altitude interception. The lack of proper material caused fires and poor

     performance.

                                                 Mitsubisi A6M3 Hamp / Zeke 32 / Zeke 22

     500 rpg. machine guns in the upper cowl.

     increased turning circle and decreased range.

     Wing Area: 231.746 sq. ft.

 

15 July 1941: 1st flight of the A6M3 Model 32 prototype.

 

December 1941: The first of 560 A6M3 Model 22s was completed. Production of the Model 22 was

April 1942: 1st deliveries of the A6M3 Model32 to the IJNAF. Range of this model decreased at a
     greater rate than that of the A6M2 under combat situations because of the thirstier Sakae 21

     engine.

June 1943: A6M3 Model 32 No.904 was pulled from the Mitsubishi production line. It

     was given several modifications that were supervised by Mijiro Takhashi. The main

     Engine:

     92 octane fuel:   1,130 hp./T.O.,   1.,100 hp./2,850 m.,   980 hp./6,000 m.

     100 octane fuel: 1,120 hp./T.O.,   1,210 hp./2,438 m.,   950 hp../6,584 m.

     Armament: 2 x 20 mm. Type 99-2 Mark 4 cannon/125 rpg. + 2 x 7.7 mm. Type 97/500 rpg./ 

          750 m./s. muzzle velocity and 600m. range.

     Maximum Dive Speed: 460 mph.

Laurelix,

     In your sources you list "Specification and Performance of Service Airplanes

of the I.J.N. (10th September 1945). What exactly is that?
