I noted this on my website at LINK

Basically everyone started WW2 with 0.20 to 0.30 MJ of gunpower (3.7 cm US and German Guns); and then 1940, you saw a jump to 0.70 to 1.5 MJ in the 50mm weapons (US/GER/SOV), followed by a jump in late 1941 and early 1942 to a range of 1.2 to 2.1 MJ (US 75mm, Soviet 7.62 cm, German 7.5 cm).

That had enormous implications; for many tanks had been designed years earlier with protection schemes for the prior generation of gunpower, and there just wasn't enough time to replace them (production needs).

This affected everyone's medium tank families:

US: Sherman
GER: Panzer IV
SU: T-34
UK: Cromwell

But for obvious reasons, since WW2; everyone focuses on the Sherman.
