Does anyone have or know if the Navy provided a graph or numbers for the climb test?
Thanks

Interesting. I have seen three or four other comparisons saying the Vorsairs was superior to the P-51, but never this document.
Interesting that the Corsair is more maneuverable, but not surprising. One of the requirements for a Naval aircraft is good low-speed handling, which naturally translates into good maneuverability at medium speeds. The F4U seems to carry this into higher speeds.
I'm pretty sure an F6F will ALSO out-maneuver any P-51 since it has the most wing area of any single-seat WWII fighter, but it is also slower and likely has not as good roll performance.
The Super Hellcat turned into the Bearcat, but would likely have been a sure winner absent the F8F
The choice of the F4U over the P-51 / P-47 / F6f in Korea is starting to be more clear.
Note that F4U running very high MP compared fleet standard, and to P-51B 67", when 115/145 or 130/50 fuel was available to boost to 75". Note also that P-51B was carrying wing racks to slow it down about 12mph and reduce 500fpm in climb.Does anyone have or know if the Navy provided a graph or numbers for the climb test?

Yes, thanks for your response. I've never put too much stock in this test since the Corsairs weren't standard production aircraft drag wise plus one ran at 65" instead of the normal 60" of boost. The Navy claimed that in the climb test "the F4U's are everywhere superior in climb, having an estimated margin of from 750 feet to 1,000 fpm at various altitude levels." In this first loadout, the P-51B weighed 9,423 lbs. and the F4U's weighed 12,162 lbs. (one ran at 65", the other at 60") In the second loadout, the P-51 weighed 9,100 lbs. the F4U's weighed the same 12,162 (same boost settings) with the Navy stating at this loadout "the F4U's are superior in climb to 20,000 feet and the P-51B superior above that altitude to ceiling." Neither of those Navy quotes make sense to me except the P-51B being superior above 20,000 feet. That's why I wondered if there's any data or chart to back up what the Navy said.Note that F4U running very high MP compared fleet standard, and to P-51B 67", when 115/145 or 130/50 fuel was available to boost to 75".

Didn't look to the load outs to see if both were flown at full internal load - and as far as turn and roll performance, pilot skill matters.
agreed, Corsair or Mustang, is like asking Cindy Crawford or Charlize Theron.Sort of like choosing "the most beautiful woman," which is very dependent both on the observer and possibly on how many clothes she is not wearing at the time.
In the comparison, it would definitely be superior, save possibly turn - but the available HP delta would probably tip the scales at low altitude - above 20K+ it should dominate everywhere but roll.Also the P-51 uses the 1650-3 geared for high alt instead of the 1650-7 geared for more Performance in lower altitude.
The clean P-51 with 1650-7 and 75inches might come out on top.
about 17mph faster at full throttle height.the clean P-51B with 75" seems a bit faster
My take on this is that the this test was rather "cooked" to push the performance of the F4U-4.Note that F4U running very high MP compared fleet standard, and to P-51B 67", when 115/145 or 130/50 fuel was available to boost to 75".

Beg pardon? There were a lot of P-51s in Korea, particularly in the early days.Interesting. I have seen three or four other comparisons saying the Corsairs was superior to the P-51, but never this document.

I'm pretty sure an F6F will ALSO out-maneuver any P-51 since it has the most wing area of any single-seat WWII fighter, but it is also slower and likely has not as good roll performance.

Ironically, albeit post war, the USN did do simulated carrier landings with a hooked P-51H or two, and it did better than the similarly converted P-51D (better low speed handling, better load factor and strength/durability at combat or landing weight, etc). The USN and Grumman also used a P-51H, but that was for R&D into airfoil research, and was otherwise a standard P-51H (not converted for simulated carrier landings).
+1 on that.My take on this is that the this test was rather "cooked" to push the performance of the F4U-4.
I'm not sure that many enthusiasts insist that the bent wings were on the Corsair directly because of the big prop. The big prop required a lot of height difference between the prop hub and the ground/deck. Going with the wing with even a small dihedral would've meant that the U/C legs are inordinately long, and long legs will be more prone to breakage than the short legs. Thus the bent wings - use this type of layout so the legs can be shorter and thus stronger.And for those who may still insist that the Bent Wings on the F4U was to allow the large diameter propeller, I have to point out that the prop on the F4U-1 is, in fact an F6F propeller - Same Hub and Blades.
With the P-47s unlimited range and payload coupled with its complete invulnerability I am surprised it isnt still being made, in fact it is a wonder the USA made anything else. There is a fantastic series of Youtube videos on the P-47 explaining it all.Brings me back to the thought that if the USAF had held on to the P-47 instead of the P-51D we'd have lost a lot fewer fighter-bomber pilots in Korea than we did.
