This model is the float plane version produced by Nakajima. It was delivered to the J.N.A.F. before the end of 1942. And first entered combat operations at Guadalcanal. The only graphs I have for this variant are from the T.A.I.C. report 103.

Altitude.Speed/Climb
Meters...mph / fpm
S.L......228/2270
.1,000...238/2321
.2,000...248/2372
.3,000...258/2423
.4,000...268/2474
.5,000...272/2170
.6,000...267/1772
.7,000...260/1374
.8,000...250/-964
.9,000...235/-578
10,000....../-180

Speed: FTH: 273 mph./4,481.7 m.

 

Climb: Critical altitude: 2,485 fpm./4,207.3 m.

TIME TO CLIMB: There is a graph for this, BUT I do not believe it is accurate. It shows 4.3 minutes to 10,000 ft. and 8,7 minutes to 20,000 ft. which is quite plausible. But it also show 2.0 minutes to 5,000 ft. Note the A/C's maximum climb rate. The only way it could climb to 5,000 ft. that quickly would be in a zoom climb.....I'm just saying that is why I did not post the figures I deciphered from the T.A.I.C. graph dated December 1944.

Combat Ceiling: 26,040 ft.
Operational Ceiling: 30,165 ft.
Service Ceiling: 33,465 ft.

Armament: 2 x 7.7mm /500 rpg. + 2 x 20mm / 60 rpg.

Range: 630 mls / 122 mph / 1,500 ft / 87 gallons internal. 1,585 mls / 124 mph / 1,500 ft / 233 gallons maximum external.

Engine: Nakajima Sakae 12: 925 hp. @ take off. 935 hp.W.E.P @ 13,800 ft.

Wing Loading: 22.44-lbs./sq.ft.

Power Loading: 5.797-lbs./hp.

Combat Weight: 5,420 lbs.

Note 1: The low wing loading of this bird allowed it to turn inside most other maneuverable fighters even with Its pylons. The pylons however, greatly reduce roll rate.

Note 2: Even with flotation pylons this A/C was able to climb to altitude faster than a P-40E. 30,000 ft. reached in 16.5 minutes according to the graph.

From The Mitsubishi A6M2 Zero-Sen, Profile Publications No.129 by Rene J. Francillon:

  

     " Despite the drag of the float installation and its engine delivering only a maximum of 950 hp., the A6M2-N was

quite fast and its maneuverability was still superior to that of most Allied single-seat fighters. A total of 327 A6M2-N's

were built by Nakajima in their Koizumi plant between December 1941 and September 1943."
