Im aware of that Widewing.
I was just saying that comparing it to a P51D is silly since the airframe was designed in 1940-1941.
If he wants to compare it then he should compare it to a similar plane. Like the P47N or Do335. Very late war planes.
I'm sorry, but you have made an incorrect assumption. Vought designed the F4U airframe in 1939! Structurally, there is little difference between the F4U-1 and the F4U-4. In fact, one could argue that the P-51D was substantially more different from the NA-73X (or even XP-51) than the F4U-4 was from the XF4U-1 of 1940. Moreover, the XF4U-1 flew 6 months BEFORE the NA-73X.
But wait, let's look even closer. North American's Mustang had to be re-engined to attain the level of performance seen in the P-51D/K. Vought's design was such that the F4U-4 did not require a complete engine swap, but merely used an improved version of the same engine that powered the prototype. Vought's design was still in frontline service in the French Navy long after the P-51D had been sold off to third world air forces or relegated to hobbyists and air racers.
What about the P-47N? Well, its basic airframe was designed in 1940, and test flown one year to the day AFTER the XF4U-1. In the case of the N model, it was designed as an ultra-long range escort fighter. As a fighter bomber it was no better than the D model. In fact, it accelerated slower, climbed slower and offered no improvement in overall agility. It was, however, faster if you had the extra time to wait for it to slowly wind-up to speed. Remember, the P-47N had a basic weight of over 11,000 lbs as compared to the F4U-4's basic weight of 9,300 lbs. Max takeoff was about 21,000 lbs for the P-47N and "normal" max of 14,000 lbs for the F4U-4, which could be "overloaded" to 16,830 lbs. In other words, the F4U-4 could fly circles around the P-47N, haul nearly 50% more ordnance and was at least as resistant to battle damage. In the Jug's favor was a speed advantage at very high altitude and considerably greater range. However, range is seldom a major consideration for close support and attack missions.
You have forgotten the classification. We are discussing fighter-bombers.
As to the Do 335, it was designed as a bomber interceptor, not a fighter-bomber. Moreover, although it was fast, it was no match for the far more agile single engine fighters swarming over Germany. Should I mention that only 13 Do 335A-1 and A-12 (two seater night fighter version) were completed before the war ended?
