The Soviet Union mainly produced tanks and aircraft. None of which were technologically advanced, let's be honest. They were rugged designs of easy maintenence and build.
The T-34, the Soviet MBT, was comparable in everything to the M4 Sherman. By that I mean it got burnt with ease by the Wehrmacht tanks but it over-whelmed them with far superior numbers.
Aircraft, the same.
Almost everything else was supplied by the Allies. We sent them oil, food, trucks, jeeps, APCs, boots, coats, radios, telephone wire, metal roads, guns, tanks, aircraft.
The Arctic Convoys going to Murmansk and ArchAngel'sk delivered, well, here's some numbers; 16 percent of Soviet tank production, 12 percent of Self-propelled guns (that includes mobile-AA) and 100 percent of armoured personel carrier production.
In 1941, 487 Matildas, Valentines and Tetrachs were received from Britain and 182 M3A1 Light Tanks (Stuarts) and M3 Medium Grants. A year later it had risen to 2487 from Britain and 3023 from the U.S.
Britain and her empire diverted 14% of her total war production to the Soviet Union.
The U.S supplied 501,660 'trucks which consisted of 77,972 Jeeps, 151,053 1 ton trucks and 200,662 2 ton trucks.
All together Britain, Canada and the U.S provided the Soviet Union with 22,800 armoured vehicles.
The Soviet Union received 342 M2 Half-Tracks, 2 M3s, 421 M5s and 413 M9s. For those who don't know the different marks largely depended on the size, in those.
They also received (I thought it was M16s) 1000 M17s and 100 M15A1s. M17s look like that M16 I showed and carried the same quad Browning .50 cal. The M15 carried a single auto-matic 37mm. Mobile AA.
I have loads of numbers of the individual tanks but I'm not going through them all. Interestingly enough though at the Battle of Prokhorovka, part of the Kursk battle, the only heavy tanks available to the 5th Guards Tank Army were 35 Churchills.
No matter what Soviet propaganda may tell, the Soviet tank crews liked many of the Allied tanks, especially the M4A2 Sherman and Infantry Mk.III Valentine.
I forgot aircraft but the only numbers I know are 3000 Hurricane IIB and Cs and 1,300 Spitfire Vbs. Also, a few Hurricane IID and IVs - I think around 60 IID and IVs but I'll have to find my source to remind me.
