From 'Tank Buster vs Combat Vehicle P.67 re Battle of the Bulge..
"During the period 16-27 Dec' the 9th AF flew a total of 4,860 sorties against all kinds of ground targets. The recorded claims of their P-47 groups totalled 479 tanks & other AFVs & 1,356 motor
vehicles destroyed or damaged.
During the same period the LW achieved more than 1,600 sorties by day, but it is not known if any of these involved the use of airborne anti-tank weapons."
& P.68, re losses to A2G heavy fighters..
"There was no gradual decline of these losses until the last month of fighting; even in Feb' 1945,
just 2 months before the end, 150 P-47s & 57 Typhoons were lost."
The Germans also tried night A2G attacks.. P.68.
"...attempts were made to attack Allied armour, motor vehicles, HQs & dumps at night by Ju 87D-7
night-attack bombers usually working in pairs, while NSGr 20 operated at night with FW 190G-2 fighter-bombers, but this was hardly 'tank busting'."
& P.46 -47,
"...the most suitable fighter types had also been narrowed down, & thanks to its inherent stability & rugged construction the P-47 was a clear favourite."
"Of the 18 FGs under the 9th AF on 5 June `44, no less than 13 were equipped with the P-47
Thunderbolt, by then already established as the most powerful contemporary American fighter-bomber."
