Nakajima A6M2-N RUFE

Japan was the only nation to produce and deliver into service float-equipped single-seat interceptor fighter seaplanes (the British Spitfire float adaptation did not progress beyond the experimental stage). When in 1940 the Japanese navy initiated the design of a new interceptor seaplane (the Kawanishi N1K1 Kyofu, or 'Rex'), the need was also expressed for a stopgap aircraft and the Nakajima company was instructed in February 1941 to develop a float-equipped version of the excellent Mitsubishi A6M2 Zero naval interceptor. As evidence of Japan's long-standing plans for territorial expansion through the Pacific, it had been recognized that in the inevitable 'island-hopping' war there would be few ready-made air bases from which to provide air cover during the occupation of the smaller islands, and that the construction of runways would be impractical. Although equipped with almost a dozen aircraft-carriers, the Japanese would be unable to use them in support of every single island invasion.

After removing the wheel landing gear and fairing over the wheel wells of a standard A6M2, Nakajima mounted a large float under the fuselage by means of a forward-raked central pylon and a pair of V-struts below the cockpit; two cantilever stabilizing floats were also mounted under the wings. The standard Zero gun armament was retained, and the first prototype was flown on 7 December 1941, the day on which the Japanese navy attacked Pearl Harbor.

Entering production as the Nakajima A6M2-N and codenamed 'Rufe' by the Allies, the new fighter still displayed a creditable performance, being first issued to the Yokohama Kokutai and deployed to Tulagi in the Solomons where the Japanese had first landed during the Battle of the Coral Sea. However, almost all the 'Rufes' were destroyed in a strike on the seaplane base by 15 Grumman F4Fs from USS Wasp on 7 August 1942. Better success attended the 'Rufes' which fought in the later Aleutian campaign, but losses soared as soon as American fighter strength could be built up. During the final year of the war, when American heavy bombers and naval aircraft opened their great attacks on the Japanese homeland, 'Rufes' of the Otsu Kokutai, based on Lake Biwa, were thrown into the battle as interceptors in defence of Central Honshu but suffered very heavy losses. Total production of 'Rufe' amounted to 327 before being halted in September 1943.

The seaplane interceptor concept was outdated from the start but using the Rufe as catapult launched seaplana wasn't a bad idea

How do you pronounce "rufe" Is it roof or rough?

I have to agree with Griffin about the identity of the floatplane at the Adm. Nimitz Museum. I was there back in the late 1960's when they had a Kawanishi N1K Kyofu (Rex) on display out in the open air. It was in excellent condition and whoever bought it later on might have wanted to restore it to flyable condition.
Only 97 Rex's were ever built making them rarer and probably even more expensive to obtain than the Rufe.

There is a fine example of this aircraft in storage at the National Museum of Naval Aviation. This aircraft is not on display and cannot be viewed by the public.

Effectively Jim,a sole Rufe was captured by Russia in Manchuria in 1945 october and was tested during 5 months and finally in 1946 march the plane was scrapped

Was any rufe captured by russians?

It was not a Rufe, it was a Rex (Kyofu). They sold it and the SBD to buy the PT boat.

There is an intact,original, unrestored....in very good condition "Rufe" at the Pacific War Museum in Fredricksburg, Texas. The museum is directly behind the Admiral Nimitz Museum on Main St. The Rufe was not on common display the last time I was there in 2004 but, a docent took me into the storage area to view it because of intense interest. It was magnificent and I have photos of it.

Is there anywhere in North America or even in the entire world that one of the A6M2-N floatplane has been preserved and put on display?
Thank you
