Er chaps, I suggest that you bone up on "lend-lease" that the US offered us prior to their entry into the war - we couldn't have kept the sea-lanes open without them (Liberty Ships, Corvettes and LRPA Liberators) and well over 25% of the British Military's equipment was from the USA for North Africa, Italy, Normandy, Arnhem and Far East campaigns (Sherman Tanks, DC3 Dakotas, P-40 Tomahawks, Liberators, Catalinas, Jeeps, Lee-Grant Tanks, etc...).
Here's the idea of the ships:
Type # Class Years Country
Carrier BAVG 5 Long Island 1941-42 UK
Carrier CVE 29 Brogue 1942-43 UK
Cruiser (CL-5) 1 Milwaukee 1944 USSR
Coast Guard Cutter 10 Lake/Chelan 1941 UK
Weather Patrol (WAG) 3 Wind 1945 USSR
Destroyer (DD) 50 Wicks,Clemson 1940 UK
Destroyer Escort (DE) 46 Buckley UK
Destroyer Escort (DE) 8 Cannon,Evarts Brazil,China
Frigate (PF) 27 Tacoma USSR
Gunboat (PG) 10 Corvette
Patrol Craft (PC) 44 PC-461 FR,USSR
Sub Chaser (SC) 142 SC-497 FR,USSR
Mine Sweepers (AM) 35 Admirable USSR
Motor Torpedo Boat (PT) 185 several USSR
Submarines (SS) 9 R-,S-boats 1941 UK
Oilers (AOG) 3 Halawa France
Liberty Ships ?of 2,710 UK
Landing Ships 35 LST UK, Greece
Plus, the "lend lease" for the Soviets was immense - some 18,700 aircraft for starters (about 20% of all their military aircraft)
So no, the Soviets did not win the war - we all did, but without the US I doubt whether the UK and Soviet Union would have managed.
