Gaah!! I swear the F6F is the Rodney Dangerfield of WWII fighters..."No respect, no respect I tell ya..."
Hellcat essentially won the Battle of the Marianas single-handedly, few planes can claim to have won a battle, but that's just not good enough for Corsair fanboys, is it?
Keep in mind we are talking about WARTIME aircraft and not who we would bet on in an air race here, okay?
The F4U was an impressive plane but wouldn't it be important for a carrier-based fighter, to, you know, actually be able to operate off carriers without design modifications or radically altering landing techniques?
Weird, isn't it, that the Hellcat didn't have teething problems? Maybe because it was designed to be easy to fly for inexperienced pilots, easy to produce, easy to keep operational in combat conditions, and to be rugged enough to get an inexperienced pilot back to the CV if he makes a mistake and catches some hits... and maybe such "irrelevant" or "unglamorous" qualities might just have been desirable, if, say, one had a naval force which was rapidly expanding in size over a short period of time, which, not coincidentally, would apply to the US Navy in late 43-44....
Oh ,yeah, and it was also 2/3 the price of the Corsair...and it was a good enough design initially that it was only produced in two major variants with relatively small changes between them.
Oh, and it was still plenty good enough performance-wise to shoot down the enemy in droves...
Maybe the F4U could have racked up huge kills in Marianas/Leyte Gulf if Chance-Vought designers might have thought about carrier handling characteristics, etc, instead of obsessing over squeezing out the last MPH from the airframe?
Sure, they eventually got F4U's on carriers and they did well but by that time the major naval-air battles of 1944 in Marianas/Leyte had been won...by Hellcat pilots.
But who cares? Looking cool, having your own TV show, and having awesome on-paper performance is far more important, right?
The Corsair did serve much longer but don't kid yourselves...it was for its bomb-trucking abilities rather than anything else once jet fighters came around. Grumman had an XF6F-6, which was an upgraded Hellcat, in the works, but decided to opt for the Bearcat, which wasn't as good a bomb-truck as the Corsair because the Bearcat was all about stuffing the biggest possible engine in the smallest possible airframe to get mega-performance, rather than being able to haul ordinance.
Not saying the Corsair wasn't a good aircraft, just saying that IMHO way too many people dismiss the Hellcat with the casual wave of the hand because the F6F's truly outstanding qualities aren't in the "sexy"
categories.
I can't vote for the late-war Japanese entries for the simple reason that if you ask me, they are vastly overrated, too little, too late, and what's the point of great airplanes when you have no functioning pilot-training program or can't produce reliable engines?
