Yes 15,000 Sherman’s as well. Although I remember it being P-40 and P-39s mostly?
There is another article I read that talks about the critical British Armor sent to the USSR right before the Battle of Moscow. The Nazis and commies and blown the crap out of each other tanks so that the British armor made up 1/3 of all medium types available for the battle to the Red Army.
I forgot about the Sherman’s

This is an interesting piece on us giving the light bombers to the Soviets, at the time I didn’t even know that, also I think there was a US Navy program to lend ships to the Soviet Navy around the time they declared war on Japan, need to find it again.
The T-34 was superior to the Sherman. A German General saw the T-34 for the first time early in Barbarossa and remarked that if the Russians could mass produce it, Germany would lose the war.
