There have been claims from P-47, P-38, P-51D/K and FW-190D pilots that they all broke the sound barrier during the war trying to dive away from attackers. Of those four aircraft I would say that the P-51D was the one that was most probable to do it. The radials and the P-38 probably are too draggy. To the best of my knowledge the FW-190D used a wood prop due to wartime shortages of metal so I don't think it would have been able to either.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

No prop plane has ever broken the sound barrier,it is not possible with the kind of aerodynamics in use at the time.
The fastest recorded WW2 prop plane was a Spitfire MK. XI Photo-Reco plane that was used in tests at Boscombe Down for transonic research and it was dived to Mach 0.82.

L-188, it is physically impossible to break the sound barrier on a prop-engined AC because the propellers lose efficiency on transonic speeds, so the pilots merely experienced the instability caused by transonic speeds on those fighters.
WW2 sound barrier? I heard about the Me-262 breaking it, only to crash making a big crater on the ground. So, I don’t think that counts

It´s quite a while ago but I remember having read in Guinness book of records that the Republic P 47 holds the speed record for WWII-prop-fighters (it was reported to be 806 KMH's if memory serves me well)
Now this source was stating nowhere wether this record was set up during WWII or in post war-period nor was it mentioning the version of the "Jug" that was involved.

I read recently an article debating the "supersonic" Spit at Boscombe Down - I can't recall the details but will try and dig it out. But if we're talking about operational production aircraft in level flight, then the Hawker Tempest and and Focke Wulf Ta152 must be contenders.

As Colin suggested, it would be wise if you specified "operational fighter speed in level flight." This would have prevented all the supersonic dive legends that have appeared in response to your question.
I believe NKP S2 was correct. It was the P-47M interceptor version of the Thunderbolt. The P-51H was not as fast and didn't see service in WWII.
Glenn-Had you posted a shot of a Sea Fury the shameless plug would have worked for me. Is that wide-and-slow thing you posted related to the Provost, or are you going to tell me the Australians made that many mistakes on one design?
