Well, yes and ... no ... it is a rather complex and sadly very often overlooked chapter of WW2. Since this is really getting off topic ...
(...) since the collapse of the Soviet Union, a trickle of information has emerged from archives in Moscow, shedding new light on the subject. While much of the documentary evidence remains classified “secret” in the Central Archives of the Ministry of Defense and the Russian State Archive of the Economy, Western and Russian researchers have been able to gain access to important, previously unavailable firsthand documents. I was recently able to examine Russian-language materials of the State Defense Committee—the Soviet equivalent of the British War Cabinet—held in the former Central Party Archive. Together with other recently published sources, including the wartime diaries of N. I. Biriukov, a Red Army officer responsible from August 1941 on for the distribution of recently acquired tanks to the front lines, this newly available evidence paints a very different picture from the received wisdom. In particular, it shows that British Lend-Lease assistance to the Soviet Union in late 1941 and early 1942 played a far more significant part in the defense of Moscow and the revival of Soviet fortunes in late 1941 than has been acknowledged.

There have been a few very crucial battles that the Soviets won in 1941 and 42, and British supplies played a crucial role here, it might have been THE life saver for the Soviets in those engagements. Who knows?. Particularly those two first years against the Germans have been the heaviest in losses for the Sovietunion, in terms of men and material. For example, during Barbarossa the Soviets lost more then 20 500 tanks in 1941! That's 7 times the size of the whole German tank army in just 6 months!
If you take a closer look at the battle of Moscow for example, it shows how important the British aid was for the Soviets in this short period, before their own production and industry took over, which was in mid/late 1942. Moscow was a turning point for the Soviets in the war. And it is hard to say, what would have happend Moscow and other key battles on the east front without the British support.
(...)The tanks reached the front lines with extraordinary speed. Extrapolating from available statistics, researchers estimate that British-supplied tanks made up 30 to 40 percent of the entire heavy and medium tank strength of Soviet forces before Moscow at the beginning of December 1941, and certainly made up a significant proportion of tanks available as reinforcements at this critical point in the fighting. By the end of 1941 Britain had delivered 466 tanks out of the 750 promised.
The point is, I am not saying that British supplies won the war on the east. But if the Brits did nothing to support their Soviet ally? Who knows what might have happend ... Lend Lease as a whole played a huge role for the Soviet war machine, but I think the Brits, played the most important role, simply beacuse they have been so quick with their support! Beating the Germans in 1941 and 42 seemed like a very difficult task and a gamble, particularly as the US faced a very serious adversary with the Empire of Japan in 1941 and 42!. But After 1943? Beating both Japan and germany, was just a matter of when, not if. So the supplies that the Soviets received in 1941 and 42 have been proably a lot more crucial to their war efforts. You know, if the american supplies have been like a sledge hammer blowing at the German body, then the British ones have been like a needle, but to the heart.
(...)Once again, raw figures do not tell the whole story. Although British shipments amounted to only a few percent of Soviet domestic production of machine tools, the Soviet Union could request specific items which it may not have been able to produce for itself. Additionally, many of the British tools arrived in early 1942, when Soviet tool production was still very low, resulting in a disproportionate impact. The handing over of forty imported machine tools to Aviation Factory No. 150 in July 1942, for example, was the critical factor in enabling the factory to reach projected capacity within two months.
Lend-Lease aid did not “save” the Soviet Union from defeat during the Battle of Moscow. But the speed at which Britain in particular was willing and able to provide aid to the Soviet Union, and at which the Soviet Union was able to put foreign equipment into frontline use, is still an underappreciated part of this story. During the bitter fighting of the winter of 1941–1942, British aid made a crucial difference.
