Nakajima C6N Saiun/Myrt
« on: February 16, 2014, 08:16:13 AM »

Hi! As most of you know, today we have many Japanese Navy aircrafts, including late war D4Y, B7A and even a project that has never been in battle - A7M in Il-2. I think that a very good additional to them would be a Japanese late war Recon/Torpedo Bomber/Night fighter carrier-based plane Nakajima C6N "Saiun" (amer. code name "Myrt"). It is a very interesting plane and I would like to ask somebody to make it (I'm not so good in modding to do it myself). If you want to know about Saiun, then read the article below (it's from wiki :) ).

The C6N originated from a 1942 Imperial Japanese Navy specification for a carrier-based reconnaissance plane with a top speed of 350 knots (650 km/h) at 6,000 m and range of 2,500 Nautical miles (4,960 km). Nakajima's initial proposal, designated N-50, was for a craft with two 1,000 hp engines housed in tandem in the fuselage, driving two propellers mounted on the wings. With the development of the 2,000 hp class Nakajima Homare engine though, this configuration was abandoned and Nakajima decided on a more conventional single-engine layout. However, the Homare's output turned out to be less than initially expected, so the design had to be optimized in other areas. The resulting aircraft was designed around a long and extremely narrow cylindrical fuselage, just large enough in diameter to accommodate the engine. The crew of three sat in tandem under a single canopy, while equipment was similarly arranged in a line along the fuselage. The C6N's low mounted laminar flow wing housed fuel tanks and was fitted with both Fowler and slit flaps and leading edge slats to lower the aircraft's landing speed to ease use aboard aircraft carriers. Like Nakajima's earlier B6N "Tenzan" torpedo bomber, the rudder was angled slightly forward to enable tighter packing on aircraft carriers.

The first flight was on 15 May 1943, with the prototype demonstrating a speed of 639 km/h (345 kt, 397 mph). Performance of the Homare engine was disappointing, especially power at altitude, and a series of 18 further prototypes and pre-production aircraft were built, before the Sauin was finally ordered into production in February 1944.

Although designed for carrier use, by the time it entered service in September 1944, there were few carriers left for it to operate from, so most were used from land bases. Its speed was exemplified by a famous telegraph sent after a successful mission: "No Grummans can catch us." The top speed of the Grumman F6F Hellcat was indeed of the same level, so overtaking a Saiun was out of the question.

A total of 463 aircraft were produced. A single prototype of a turbocharged development mounting a 4-blade propeller was built, this was called the C6N2 Saiun-kai. A night-fighter version C6N1-S with oblique-firing (Schräge Musik configuration) single 30 mm (or dual 20 mm) cannon and a torpedo carrying C6N1-B were also developed. The C6N1-B developed by Nakajima was not needed after Japan's aircraft carriers were destroyed. As Allied bombers came within reach of the Japanese home islands, there became a need for a first class night fighter. This led Nakajima to develop the C6N1-S by removing the observer and replacing him with two 20mm cannons. The C6N1-S's effectiveness was hampered by the lack of air-to-air radar, although it was fast enough to enjoy almost complete immunity from interception by Allied fighters.

Despite its speed and performance, on 15 August 1945, a C6N1 was the last aircraft to be shot down in World War II. Just five minutes later, the war was over and all Japanese aircraft were grounded.

yeahh what a great request!

those birds are really needed! they functioned as a form of AEW for the defending IJN fighters against incoming USN strikes;
the 343rd had some of those on roster for exactly that duty...

This fine looking plane is considered one of the greatest aircraft designs of WW2.
It was planned from the drawing board to fulfill an ambitious (and unique!) requirement from IJN that demanded almost impossible specifications concerning to speed and range for that time.
Unfortunately, as already said, the carrier fleet from which it was intended to operate did not exist anymore when the plane was service ready...
Great request!

I was very close to making a request for this very plane the other day. Now I
don't have to! Thank you for creating this topic.

You are welcome  ;) I was thinking about doing this for some time, too... But at that time I couldn't find password from my SAS account   :D
