Why the USAAF gave up on the A-36 in favour of the P-47.

[Kutscha]

The so called high performance German fighters did not appear in units til the fall of 1944 and in any great numbers to the very late fall of 1944. The 1.98ata Me109K-4 did not appear, and then only in penny pocket numbers if at all, til late March 1945. By mid April the 4 Gruppe authorized to use 1.98 boost had retreated to south east Germany where it was very unlikely they would encounter any Spitfires of any Mark.

To put the numbers of German fighters, by type, available on can look at Bodenplatte. Of the 990 fighters the following is the percentage:

Fw190A-9 > 2,5%
Fw190A-8 > 27.3%
Fw190D-9 > 18.6%
Me109G-6 > 0.2%
Me109G-10 > 6.3%
Me109G-14 > 18.8%
Me109K-4 > 11.9%
Me109G-14/AS > 14.4%
