I started two parallel campaigns, USN one with Wildcats and IJN with Zeros... I'm quite surprised that A6M3 doesn't feature in the IJN airplane selection screen http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif . I'm aware that airplane doesn't have a hook but by the time it is available to my squadron it shouldn't matter, since Japanese carriers... well. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Also About F4U-1C... it is available only in Iwo Jima and not in later campaigns... have these been pulled from combat ops later on (historically) or is it another DGen aberrance http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif ?

I think the F4U-1C was withdrawn from service because it's cannons were unreliable.

F4U-1C should be in service from April '45 to the end AFAIK. They weren't withdrawn from service, but were briefly restricted to lower altitudes due to gun heaters not being installed because somebody at USN Bureau of Ordnance cancelled high-alt tests. http://forums.ubi.com/images/smilies/53.gif Pilots discovered this the hard way. Shortly thereafter, the restriction was lifted.

As far as A6M Model 32, my understanding is that they weren't particularly numerous outside of New Guinea. I think the Model 22 was more common, but we don't have that in IL2.

F4U-1C were only a few that saw action , something like 155 F4U-1C were sent in front lines , other sources says only 200 were produced so they really appeared in tiny numbers compared to other USN variants

For A6M3 , i have campaigns where it is available , in any case , you can modify this quite often by going in Dgen folder and search for "Planes INx" (x being a number ) for IJN , "Planes UNx" for USN , those files display planesets for each campaign , so you just have add A6M3 or F4U1C in the list http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Thank you guys... I am just crazy for as much as possible historical accuracy... therefore I wont use Hamps if they weren't historically used by IJN at some of the available theaters in game http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif .

I'll look into it...


Also F4U-1C being represented by 155 types on PTO... good enough for me http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif .

BTW can anyone explain lack of Hook under A6M3 fuselage, thus making it effectively unusable for carrier ops http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif . Funny, I always though A6M3 was a carrier borne navy fighter.

they saw the need fopr more performance, and stuck a better engine in the M3s

this necessitated removal of the forward fuselage fuel tank

range suffered a lot, enough that the IJN to decide they were not feasible for carrier ops, so they used them for IJN land bases until the tankage increased again in follow-on models

with carrier ops not in the cards for the M3s, they also did away with hook, wingtip folding, etc

In mid-1941, work began on a new version of the Zero Fighter, the A6M3 powered by a 1130 hp Sakae 21. This engine was equipped with a two-speed supercharger instead of a single-speed unit as used on the earlier Sakae 12. The new engine required that the firewall be moved 8 inches further aft, which reduced the fuselage fuel capacity from 21.6 Imp gall to 13.2 Imp gall. The shape of the engine cowling had to be changed in order to incorporate the supercharger air intake in its upper lip.
The first A6M3 flew in June of 1941. Although the aircraft performed satisfactorily, the flight trials of the A6M3 were somewhat disappointing since performance figures fell below the calculated values. In addition, production had to be delayed until sufficient numbers of Sakae 21 engines became available.

The type was placed in production as the Navy Type 0 Carrier Fighter Model 32. Beginning with the fourth aircraft, the ammunition supply for the wing-mounted 20-mm cannon was increased from 60 rpg to 100 rpg. Soon thereafter, in order to simplify production and maintenance, the folding wingtips and the tab balances were removed, reducing the wingspan to 36 feet 1 1/16 inches and wing area to 231.75 square feet. This resulted in a slight increase in the level speed with little adverse effect in the overall maneuverability. Japanese pilots did find that both the maneuverability and climb rate of the new clipped-wing Zero Fighter were slightly poorer than those of the earlier A6M2, but the aircraft was considerably faster in a dive, the ailerons were more effective, and the roll rate was better at high speed.

343 A6M3s were built by Mitsubishi, with an unspecified number also being built by Nakajima at Koizumi.

Following limited service in Japan, the A6M3s were deployed to the New Guinea/Solomons area in the late spring of 1942 in preparation for the invasion of Australia. Initially, the Allies thought that the A6M3 was an entirely new fighter because of its squared-off wingtips, and Capt. Frank McCoy's team at the Directorate of Intelligence of the Allied Air Forces, Southwest Pacific Area, assigned it the code name HAP, after the nickname of General Henry Arnold, the USAAF's Chief of Staff. The General was not amused, and had Capt. McCoy called onto the carpet to explain just what he was up to. Capt McCoy seems to have survived this particular episode, but the code name of the new square-winged fighter was quietly changed to HAMP. When Allied intelligence finally recognized that the aircraft was not a new design but was actually a modified version of the ZEKE, it was renamed ZEKE 32.

Following the American landing at Guadalcanal, the A6M3 were forced to operate from bases 560 nautical miles away from the landing force. During this operation, a large number of A6M3s were lost because they had insufficient range. The Sakae 21 engine of the A6M3 had a higher fuel consumption rate than the Sakae 12, and this, acting in concert with the reduced fuel capacity resulting from the installation of the two-speed supercharger, had an adverse effect on range, which had been one of the strong points of the A6M2. In order to increase the range, a 9.9 Imp gall fuel tank was fitted in each wing outboard of the cannon. The folding wingtips were restored. This new version was still known under the short designation A6M3, but bore the new designation of Navy Type 0 Carrier Fighter Model 22. It could be externally distinguished from earlier A6M3 models by the rounded-off wingtips. The aircraft was known as the Navy Type 0 Carrier Fighter Model 22A when long-barreled 20-mm Type 99 Model 2 Mk 3 cannon were installed. The rounded-wingtip Model 22 became the prime carrier fighter of the A6M3 series, some 560 being built by Mitsubishi.

Thanks... some nice info there.
