Mr Erichthe figure of 472 mph for the Ta is only one pilots impression the crate could travel faster than that,,,,,,,,,,,,,,,, and gents that will be included in my book
and no there is not enough data to compare.
The XP-72 was still an experimental 480mph aircraft and it seems had about the same speed. Advanced versions with a turbo-compounded engine were supposedly expected to be capable of well over 500 mph. Someone with more knowledge of American aircraft can expand.
A turbo-compound R-4360 was some way into the future at the end of WW2.
The Ta 152 was running well ahead of the XP-72 in terms of timeline. I suspect the XP-72 would have made a faster aircraft than the Ta 152 aircraft albeit with a lower service ceiliing simply because I can't see the Luftwaffe pushing it to the point of the Jumo 222E/F engine. They would call it quits at the Jumo 213J which would leave the Ta 152 flying considerably faster than the 472mph of the 2050 hp Jumo 213E engine.
The XP-72 had a wing loading of 58.3 pounds per square foot versus 45.9 for the Ta-152H, so the XP-72 had about 20% heavier wing loading. Slightly better turning for the Ta-152H, but not decisive.
The XP-72 had a span loading of 427.7 versus 243.5 for the ta-152H. High altitude maneuverability advantage to the Ta-152H.
The XP-72 had a power loading of 5.1 pounds per horsepower versus 5.6 for the Ta-152H. Advantage XP-72 by a large margin in climb (5280 feet per minute versus 3445 FPM).
The XP-72 went 503 mph versus 472 for the Ta-152H. Advantage XP-72. The XP-72 cruised at 490 mph versus 311 for the Ta-152H. Large advantage for the XP-72, which cruised faster than the Ta-152H's top speed.
Their ranges were almost equal, so no advantage either way.
The XP-72 had a ceiling of 43275 feet versus 50036 for the Ta-152H. Advantage Ta-152H ... assuming it had time to climb higher when the enemy was sighted.
As I see it, the XP-72 could engage or disengage in combat at will and climbed a LOT better ... at least until the XP-72 reached its service ceiling, but the Ta-152H was more maneuverable, particularly at high altitude. The ability to engage or disengage in combat is the deciding factor in my book, so I'd give the real-world combat advantage to the XP-72. Not in a dogfight, mind you, but in real combat. NOBODY dogfights at 40,000+ feet in a WWII fighter. They make one pass and then almost HAVE to break off because the turn performance is almost nil at that altitude. If they even MET in combat, the fight would be "one pass, haul a**," and they well might never FIND one another if they chose to turn around and engage.
I'd say the better combat mount was easily the XP-72, but the REAL deciding factor would most probably be the pilots. Both the Germans and the Americans had good pilots, so the outcome would probably be a toss up in any single encounter. The thing is, if the XP-72 had been built, it would have been built by the Americans in much larger numbers tha the Ta-152H's were built. The Germans DID build the Ta-152, but never had more than about 25 in service at any single moment in time.
So all the Americans would have had to do to win decisively was to field 250+ XP-72's and any encounter would have been a one-sided American win, with maybe a few losses, but the Ta-152H's would have been elimiated quickly by quantity of opposition ith similar quality pilots. Since that didn't happen, we are left with fictional conjecture.
My conjecture is that, one on one, the pilot would determine the victor, not the aircraft.
I like both aircraft a lot, but the Ta-152H is, by far, the better-looking aircraft. As is often the case, looks are only skin deep and the XP-72 is a VERY worthy challenger to the mighty Ta-152H.
Then again, so is the CAC-15.
The Ta 152H with a Jumo 213E1 engine, running of B4 (87 octane fuel) with seperate tanks for supplies of MW-50 (water methanol) and Nitrous Oxide existed as a 472mph fighter and saw service.
Actually the P-72 was in production and was probably better developed than the Ta-152. Whereas the XP-72 is reported to have a very smooth flight test program except for the failure of a turbocharger on number two, the Ta-152 had a troubled flight test program with several crashes and had very few flight test hours before being produced. Operationally there were also problems with the Ta-152H and I believe it ended the war grounded.The XP-72 was still an experimental 480mph aircraft and it seems had about the same speed. Advanced versions with a turbo-compounded engine were supposedly expected to be capable of well over 500 mph. Someone with more knowledge of American aircraft can expand.
In a fair comparison one would compare advanced versions of the Ta 152. These would used the Jumo 213J (of about 2700hp) or DB603N of abour 2800hp. This is a boost of power from about 2100 to 2800 hp ie about 30% and might produced a 8% increase in speed so up to about 500 mph.
I think the aircraft would be fairly evenly matched. The promised Superbolt perhaps being faster but the Ta 152 having a higher ceiling when using GM-1.
They could hardly get it working much less doubling the hp.Advanced versions of the Ta 152 with the Jumo 222E engine, potentially of around 4000hp were proposed, this engin being on the production schedule.
Given the amount of development time and the apparently easy flight test program, I would say the P-72 was a more mature design at it cancellation at VE day than was the Ta-152.The Ta 152 was running well ahead of the XP-72 in terms of timeline.
Another test stand engine.They would call it quits at the Jumo 213J which would leave the Ta 152 flying considerably faster than the 472mph of the 2050 hp Jumo 213E engine.
Both planes are a constant pile of "what ifs" in regards to intended engines, equipment and actual performance. there is far too little reliable data to really pick a winner of service versions that were months if not over a year (or 2?) from actual service use.
The USAAF wouldn't bother with the XP-72 as the P-80A could likely be in service within the same time scale and offered more potential. The R-4360 engine would
best be used in the B-29D/B-50 bomber which had serious speed with these engines.
My source says the XP-72 cruised at 300 mphMr GregP
1) Its an extraordinary claim that a piston engine airplane with maximum speed 503mph could cruise at 490mph. In my opinion is totaly unacceptable
I do not think this is an issue.5) Ta 152 s mechanicaly driven supercharger was faster reacting during dogfights than turbos .
A number of fighters from either side were "thrown in" before they had all their bugs ironed out.Mmmm, yes, saw service, but basically prematurely thrown in to slow down the dam break.
A bold statement impossible to verify. I know little more than what google has to offer about the XP-72, but from that I get no more than two prototypes ever took to the air. The 3 Fw 190 C prototypes with mechanical supercharger likewise showed no vices I know of yet still the Ta 152 had its share of teething issues. Some problems simply only come up over time. In the Ta-152 case the Jumo supercharger gear was the main source of the problems. The XP-72 existed in the form of two prototypes of which one crashed, how many flight hours were accumulated befor the program got cancelled? Did they represent the configuration that was to be produced (e. g. contra-rotating propeller and/or dash 19 engine)?Actually the P-72 was in production and was probably better developed than the Ta-152.
With all due respect, could we please stop acting like the world is so simple you can just magically pour money and resources into any development or production you want and, by that, speed it up indefinetly?True. Too bad Germany spent so much time and money developing planes like the Ta-152 and Do-335 when they had the superb Me-262, which would really make a difference.
In fair comparison? The XP-72 first flight was Feb 2, 1944, nearly a year before the Ta and had lots of flight tests under its belt. There is a lot of difference between an engine performing in an airframe and a prototype on a test stand.

In reality the Ta-152 would already be harassed from SL to 35k by the P-51H and P-47M tag team, both aircraft in production and either fielded are ready to be. In fact, the 1943 fielded P-51B was faster from SL to 20k than the Ta-152H with the EB engine, and, probably out climbed it (don't have good climb data on the Ta). The only area where the Ta had a clear advantage over contemporary allied aircraft was above 40k ft.
Jim yes I do...........
it might be a multi-volume history on JG 301, have been working on this for some time especially in regards to the night fighter situations with the unit. please do not ask me for publication times, as I have made mention of this work on numerous threads for several years in relationship to late war 44-45 engagements
