Quoted: These threads are nearly as bad as the aviation post accident speculation here. It's okay to say or write, "I don't know", or "Here are performance charts for the airplanes, let's take a look at the differences". Instead it's the usual "derp, obviously the Corsair, it can operate from a boat, and it has an air-cooled engine", or, "Herp, the Mustang is just plain purty, it looks fast".

Quoted: I really hate finding factual errors in these kinds of web pages... "Packard version of the 1,650-horsepower turbocharged Merlin 61." The V-1650-3 fitted to the P-51B was supercharged, not turbocharged. Also, "The Corsair had 86 per cent more firepower than the P-51B because its .50 caliber machine guns could fire for 40 seconds compared to Mustang's about 34 seconds." What math did they use? Mine says that's about an 18% advantage. View Quote View All Quotes View All Quotes Quoted: I really hate finding factual errors in these kinds of web pages...

Quoted: FWIW, regarding "out turning" an opponent: I've never read an 'official' flight test of wwii a/c that includes turn rate data. Exception: 1 on 1 comparisons with other a/c, how many turns it might take to get behind an opponent and other turn rate circumstances, like speed. It's as if turn rate was a mere curiosity. Dogfighting happened, generally, among an average pilot, when/after he is screwing up or has already screwed up. Dogfighting, as a tactic, was for exceptional pilots. Maneuver was to be avoided when possible. View Quote Remember that it wasn't until even after Korea (about 1960) that the energy-maneuverability concept was even considered. This is when a more analytical view of how dogfights actually occurred was developed, and measures of turn rate and turn radius were actually made and compared. There's not even really good data today about the E-M capability of the WWII fighters because nobody is actually out there taking their multimillion-dollar museum pieces and pushing the engine or airframes to see what they're actually capable of....and it wouldn't matter, since they're not running the same fuels with the same combat weights and equipment anyway. Also realize that the vast majority of aerial victories in WWII (on both sides) were unobserved kills, where the one who was shot down likely didn't ever see who shot them down. They were kills of opportunity rather than the turn circle lufberies that we tend to think of now. Fighter pilots of the time thought more about slashing attacks than sustained turn fights with actual tracking gun shots, so that's why they were primarily concerned with dash speed or climbing ability. |

Quoted: Welp, that settles that. Doesn't that story and comparison involve a P51 "B" and not the superior "D"model? The D-model was the one produced in highest numbers for the war, and the one most of us are familiar with. But again...between these two high performance planes, the pilot will make the difference. |

When I was younger I lived/breathed air plane stuff. Being an Air Force brat we had great libraries and I check out/read all kinds of old books about WW2 and Korea.
If I remember correctly the Japanese believed the Corsair was the best fighter we had when the altitude was under 20,000 feet. The Lightning was better above 20,000 feet. The Mustang was felt to be the best all around, low or high altitude fighter we had. |

Quoted: Not exactly. A slower aircraft with a smaller turn circle can easily best a faster, more powerful adversary. It is about turn rate, turn radius, and energy....not speed in and of itself. View Quote Not in a real fight. No offense intended: I think you're writing from simulation scenarios. In a real life fight to stop an enemy from doing something, speed and firepower are supreme. Speed. Firepower. Climb. In that order was what pilots wanted. Maneuvering your fast airplane obfuscated its advantage. |

It would 100% depend upon the pilots in each and where the fight was taking place.
It also depends upon which model and when and where the fight was happening: most P-51s* cruising around at night would mostly just be waiting for an F4U-5N to sneak up on it but an AU-1 Corsair loaded down for a ground attack mission is going to be in a bad spot vs a clean P-51 ??????? If you look at most air combat,it’s very rarely a one on one duel like a perfect Maverick vs Jester scenario. Someone almost always has some form of numerical or situational advantage that means more than a small difference in aircraft performance. Simply looking at statistics doesn’t really do much in the real world,I mean the number of MiGs shot down vs Sabres shouldn’t have been so lopsided if the pilots only played trump cards and likewise the Arabs should never have looked so bad. *yes I know what an AN/APS-13 set is. |

Quoted: Not exactly. A slower aircraft with a smaller turn circle can easily best a faster, more powerful adversary. It is about turn rate, turn radius, and energy....not speed in and of itself. View Quote With speed, the pilot has the option to push the fight or leave it. You are missing the key points. The jap planes in ww2 could easily outturn the us planes from mid war forward but the us pilots used boom and zoom tactics where they would use their speed advantage to engage and disengage from the fight. They dictated the rules of the fight because they could pick their fight. The only way a faster, more powerful adversary is going to lose to a slower aircraft with a smaller turn circle is if they screw up. That is what the US and UK learned quickly in the early days of the pacific fight. Once they changed their tactics, they did a lot better. Once they started receiving faster planes, they did much better. |

Quoted: Count the total number of rounds available. View Quote OK. Per the article: "The F4Us carried 391 rounds per gun while the P-51B only had 350 for the inboard guns and 240 for the four outboard ones." Corsair 391 x 6 = 2,346 P-51B (350 x 2) + (240 x 4) = 1,660 2,346/1,660 = 1.41 So by that metric it's a 41% advantage. Significant, to be sure. But that's not my point. |

Pilot skill and chance will determine that one. The aircraft are too closely matched for technical specs to be of any predictive value. Many pilots have been defeated by opponents in technically inferior aircraft.

But, they sure understood it then and relative performance characteristics of the aircraft in ww2 were often enough to exploit speed advantages. In that time, it was the most important trait as relative speed advantage could be used to dictate the fight.

Hartmann said that most of his kills never saw him and that he wasn’t a very good shot so he fired from exceptionally close range. He learned this as Krupinski’s wingman as he preferred to not try maneuvering with the enemy,just zoom in to dump rounds and run away to repeat.
I think perhaps movies and lore has warped aerial combat into thinking it was all this ballet in the air rather than what it quite frankly was most of the time. |

Quoted: and we are still talking ww2 time frame but you choose to stick to your current and accurate to current times dogma. Again, there's nothing in the thread title that says, "only knowing what they knew in 1944." Still interested in your bonafides. If you want some more on what they did and didn't know in WWII, go take a look at Boots Blesse's 1954 Weapons School paper (a.k.a. No Guts, No Glory!) codifying the combat experiences of his Sabre squadron in Korea. Keep in perspective that most everything you read in there was a new change in what was being taught before and what was "commonly understood" by the WWII vets who had written fighter tactics up to that point. They're just scratching the tip of understanding rate/radius and energy, but can't quite put it into those words. They are putting their finger on tactics that are derived from rate/radius/energy, but they aren't getting to the root of why. They're hinting around the concepts of cornering velocity being able to produce the best rate of turn....hinting around the idea of a rate fight (although mostly as a defensive concept, rather than an offensive one)...and almost getting the single-circle/radius fight identified in their discussion of the "scissors". So, 10 years after WWII, they're just starting to be able to identify the actual reasons that some tactics have worked, and some haven't. It will be another 10 years after this before Boyd publishes his first Weapons School paper about Energy Maneuverability theory, and it will take another 5 years or so after that for E-M to be widely accepted and understood. EDIT: No Guts, No Glory PDF if anyone wants to read it. I think it's a great read. |

View Quote According to the "fly off" test results, the Corsair was faster below 15,000, at par up 25,000 and only above 25,000 did the Mustang have the lead in speed. And in all cases the speed between the aircraft were within + / - 10mph of each other, so it's not like one was a subsonic Mig 17 and the other a Mach 2 F-4 Phantom (very large speed differential). While the Corsair had more firepower (6x .50s Vs. 4 .50s in the B & C model P-51) , better maneuvering and more rugged construction & protection, (advantages) I think it would still basically boil down to who saw & struck the other by surprise first. That's always been the surest way to "win" in Air Combat. BIGGER_HAMMER Edited to add : I'm always amazed at the GD'ers who try to make "I know better" arguments against actual professionals who have really DONE these things for years or even decades. |

Let's get back to what you are telling me I'm wrong about. I said, in the context of ww2 fighters, that speed is what allows a pilot to dictate the fight. That is, with a speed advantage, the pilot has the ability to engage or disengage a slower fighter at will. You are saying rate of turn ie turn advantage is more important than a speed advantage.

If it was as simple as what you're trying to imply, no Corsair would have ever been lost to a Zero. If you look at a modern US tactics manual -- maybe there's an old 3-1 for one of the fighters on wikileaks -- and drill down to what it recommends versus a specific adversary, what you're going to see is a going-in gameplan, followed up by a long series of "if this, then that" branches of a decision tree. There's a basic strategy based on what is known about your airplane's performance and that airplane's performance, but the unknowns (where is the fight taking place, what angles, what energy state, what weapon state, fuel state, awareness/SA, mistakes made in executing your own tactic, identifying mistakes made by adversary, etc) mean that a canned gameplan is probably not going to just work. This is true even in what should be simple matchups between, say, an F-16 and a MiG-21. Bottom line: no, the guy with more speed doesn't get to "dictate the fight". Even the old platitude of "speed is life", which used to be one of the basic BFM rules during the Vietnam era, has been changed to "nose position vs energy" to account for the nuance that in some circumstances speed is not life. |

I have no bonfides relevant to this discussion.
In wwii, because of the colossal buildup of airpower, most American pilots were green. What I've timidly offered in this discussion were preferred tactics probably suited to green pilots participating in combat with opposing aircraft in numbers far exceeding any aerial combat since. Intense maneover was discouraged, I think, for the sake of the green pilots who were flying excellent a/c; and who did well enough if they stayed with their leader in combat. Most pilots were never well positioned to get a kill. A small percentage of pilots 'went after them.' The excellent agressive pilots got kills. The aggressive, unskilled go getters got killed. The skill of these excellent pilots, I think, was cataloged and taught to later pilots like ME. |

The gunnery training in the States before deployment taught basics about deflection shooting, but very little about how to maneuver into a position of advantage. Some of the 8th AF fighter units in England instituted their own on-the-job training course that they called "clobber college" for the new pilots that showed up. There were no formal tactics manuals that even existed then, so it was basically the more experienced pilots trying to pass along what they'd learned and what worked. |
