President Roosevelt signs the Lend - Lease bill to give aid to Britain and China ( 1941 ) The lend - lease policy, formally titled `` An Act to Promote the Defense of the United States '', ( Pub. L. 77 -- 11, H.R. 1776, 55 Stat. 31, enacted March 11, 1941 ) was a program by which the United States supplied Free France, the United Kingdom, the Republic of China, and later the Soviet Union and other Allied nations with food, oil, and materiel between 1941 and August 1945. This included warships and warplanes, along with other weaponry. The policy was signed into law on March 11, 1941 and ended during September 1945. The aid was free for some countries, although some countries were repaying with gold, and some military equipment were required to be returned after the war. In return for the aid, the U.S. was given leases on army and naval bases in Allied territory during the war. A total of $ 50.1 billion ( equivalent to $681 billion presently ) worth of supplies was shipped, or 11 % of the total war expenditures of the U.S. In all, $31.4 billion ( equivalent to $427 billion today ) went to Britain and its Empire, $11.3 billion ( equivalent to $154 billion today ) to the Soviet Union, $3.2 billion ( equivalent to $43.5 billion today ) to France, $1.6 billion ( equivalent to $21.7 billion today ) to China, and the remaining $2.6 billion to the other Allies. Reverse lend - lease policies comprised services such as rent on air bases that went to the U.S., and totaled $7.8 billion ; of this, $6.8 billion came from the British and the Commonwealth. The terms of the agreement provided that the materiel was to be used until returned or destroyed. In practice very little equipment was returned. Supplies that arrived after the termination date were sold to Britain at a large discount for £ 1.075 billion, using long - term loans from the United States. Canada operated a similar program called Mutual Aid that sent a loan of $1 billion and $3.4 billion in supplies and services to Britain and other Allies. This program effectively ended the United States ' pretense of neutrality and was a decisive change from non-interventionist policy, which had dominated United States foreign relations since 1931.

After the defeat of France during June 1940, the British Commonwealth and Empire were the only forces engaged in war against Germany and Italy, until the Italian invasion of Greece. Britain had been paying for its material with gold as part of the `` cash and carry '' program, as required by the US Neutrality Acts of the 1930s, but by 1941 it had liquidated so many assets that its cash was becoming depleted. During this same period, the U.S. government began to mobilize for total war, instituting the first - ever peacetime draft and a fivefold increase in the defense budget ( from $2 billion to $10 billion ). In the meantime, as the British began becoming short of money, arms, and other supplies, Prime Minister Winston Churchill pressed President Franklin D. Roosevelt for American help. Sympathetic to the British plight but hampered by public opinion and the Neutrality Acts, which forbade arms sales on credit or the loaning of money to belligerent nations, Roosevelt eventually came up with the idea of `` lend -- lease ''. As one Roosevelt biographer has characterized it : `` If there was no practical alternative, there was certainly no moral one either. Britain and the Commonwealth were carrying the battle for all civilization, and the overwhelming majority of Americans, led in the late election by their president, wished to help them. '' As the President himself put it, `` There can be no reasoning with incendiary bombs. '' In September 1940, during the Battle of Britain the British government sent the Tizard Mission to the United States. The aim of the British Technical and Scientific Mission was to obtain the industrial resources to exploit the military potential of the research and development work completed by the UK up to the beginning of World War II, but that Britain itself could not exploit due to the immediate requirements of war - related production. The shared technology included the cavity magnetron ( key technology at the time for highly effective radar ; the American historian James Phinney Baxter III later called `` the most valuable cargo ever brought to our shores '' ), the design for the VT fuze, details of Frank Whittle 's jet engine and the Frisch -- Peierls memorandum describing the feasibility of an atomic bomb. Though these may be considered the most significant, many other items were also transported, including designs for rockets, superchargers, gyroscopic gunsights, submarine detection devices, self - sealing fuel tanks and plastic explosives. During December 1940, President Roosevelt proclaimed the U.S.A. would be the `` Arsenal of Democracy '' and proposed selling munitions to Britain and Canada. Isolationists were strongly opposed, warning it would result in American involvement with what was considered by most Americans as an essentially European conflict. In time, opinion shifted as increasing numbers of Americans began to consider the advantage of funding the British war against Germany, while staying free of the hostilities themselves. Propaganda showing the devastation of British cities during The Blitz, as well as popular depictions of Germans as savage also rallied public opinion to the Allies, especially after the defeat of France. After a decade of neutrality, Roosevelt knew that the change to Allied support must be gradual, especially since German Americans were the largest ethnicity in America at the time. Originally, the American policy was to help the British but not join the war. During early February 1941, a Gallup poll revealed that 54 percent of Americans were in favor of giving aid to the British without qualifications of lend - Lease. A further 15 percent were in favor with qualifications such as : `` If it does n't get us into war, '' or `` If the British can give us some security for what we give them. '' Only 22 percent were unequivocally against the President 's proposal. When poll participants were asked their party affiliation, the poll revealed a political divide : 69 percent of Democrats were unequivocally in favor of Lend - Lease, whereas only 38 percent of Republicans favored the bill without qualification. At least one poll spokesperson also noted that, `` approximately twice as many Republicans '' gave `` qualified answers as... Democrats. '' Opposition to the lend - lease bill was strongest among isolationist Republicans in Congress, who feared the measure would be `` the longest single step this nation has yet taken toward direct involvement in the war abroad ''. When the House of Representatives finally took a roll call vote on February 9, 1941, the 260 to 165 vote was largely along party lines. Democrats voted 238 to 25 in favor and Republicans 24 in favor and 135 against. The vote in the Senate, which occurred a month later, revealed a similar partisan difference. 49 Democrats ( 79 percent ) voted `` aye '' with only 13 Democrats ( 21 percent ) voting `` nay. '' In contrast, 17 Republicans ( 63 percent ) voted `` nay '' while 10 Senate Republicans ( 37 percent ) sided with the Democrats to pass the bill. President Roosevelt signed the lend - lease bill into law on 11 March 1941. It permitted him to `` sell, transfer title to, exchange, lease, lend, or otherwise dispose of, to any such government ( whose defense the President deems vital to the defense of the United States ) any defense article. '' In April, this policy was extended to China, and in October to the Soviet Union. Roosevelt approved US $1 billion in Lend - Lease aid to Britain at the end of October 1941. This followed the 1940 Destroyers for Bases Agreement, whereby 50 US Navy destroyers were transferred to the Royal Navy and the Royal Canadian Navy in exchange for basing rights in the Caribbean. Churchill also granted the US base rights in Bermuda and Newfoundland for free, allowing British military assets to be redeployed. After the United States entered the war in December 1941, foreign - policy was rarely discussed by Congress, and there was very little demand to cut Lend Lease spending. In spring 1944, the House passed a bill to renew the Lend Lease program by a vote of 334 to 21. The Senate passed it by a vote of 63 to 1. Administration President Roosevelt established the Office of Lend - Lease Administration during 1941, appointing steel executive Edward R. Stettinius as head. During September 1943, he was promoted to Undersecretary of State, and Leo Crowley became director of the Foreign Economic Administration which was given responsibility for Lend - Lease. Lend - lease aid to the USSR was nominally managed by Stettinius. Roosevelt 's Soviet Protocol Committee was dominated by Harry Hopkins and General John York, who were totally sympathetic to the provision of `` unconditional aid ''. Few Americans objected to Soviet aid until 1943. The program began to be ended after VE Day. During April 1945, Congress voted that it should not be used for post-conflict purposes, and during August 1945, after Japanese surrender, the program was ended. Prior to his death during April of that year, Roosevelt had announced his intention to end the program from September 1945.

See Military production during World War II. Lend - Lease would help the British and Allied forces win the battles of the late war ; the help it gave in the battles of 1941 was trivial. In 1943 -- 1944, about a quarter of all British munitions came through Lend - Lease. Aircraft ( in particular transport aircraft ) comprised about a quarter of the shipments to Britain, followed by food, land vehicles and ships. Even after the United States forces in Europe and the Pacific began to attain full strength during 1943 -- 1944, Lend - Lease continued. Most remaining allies were largely self - sufficient in front line equipment ( such as tanks and fighter aircraft ) by this time, but Lend - Lease provided a useful supplement in this category even so, and Lend - Lease logistical supplies ( including motor vehicles and railroad equipment ) were of enormous assistance. Much of the aid can be better understood when considering the economic distortions caused by the war. Most belligerent powers decreased severely production of non-essentials, concentrating on producing weapons. This inevitably produced shortages of related products needed by the military or as part of the military - industrial complex. For example, the USSR was very dependent on rail transportation, but the war practically ended rail equipment production. Just 446 locomotives were produced during the war, with only 92 of those being built between 1942 and 1945. In total, 92.7 % of the wartime production of railroad equipment by the USSR was supplied by Lend - Lease, including 1,911 locomotives and 11,225 railcars which augmented the existing prewar stocks of at least 20,000 locomotives and half a million railcars. Furthermore, much of the logistical assistance of the Soviet military was provided by hundreds of thousands of U.S. - made trucks. Indeed, by 1945, nearly a third of the truck strength of the Red Army was U.S. - built. Trucks such as the Dodge 3⁄4 ton and Studebaker 21⁄2 ton were easily the best trucks available in their class on either side on the Eastern Front. American shipments of telephone cable, aluminum, canned rations, and clothing were also critical. Lend - Lease also supplied significant amounts of weapons and ammunition. The Soviet air force received 18,200 aircraft, which amounted to about 13 % of Soviet wartime aircraft production. And while most tank units were Soviet - built models, some 7,000 Lend - Lease tanks were deployed by the Red Army, or 8 % of war - time production. According to the Russian historian Boris Vadimovich Sokolov, Lend - Lease had a crucial role in winning the war : On the whole the following conclusion can be drawn : that without these Western shipments under Lend - Lease the Soviet Union not only would not have been able to win the Great Patriotic War, it would not have been able even to oppose the German invaders, since it could not itself produce sufficient quantities of arms and military equipment or adequate supplies of fuel and ammunition. The Soviet authorities were well aware of this dependency on Lend - Lease. Thus, Stalin told Harry Hopkins ( FDR 's emissary to Moscow in July 1941 ) that the U.S.S.R. could not match Germany 's might as an occupier of Europe and its resources. Nikita Khrushchev, having served as a military commissar and intermediary between Stalin and his generals during the war, addressed directly the significance of Lend - lease aid in his memoirs : I would like to express my candid opinion about Stalin 's views on whether the Red Army and the Soviet Union could have coped with Nazi Germany and survived the war without aid from the United States and Britain. First, I would like to tell about some remarks Stalin made and repeated several times when we were `` discussing freely '' among ourselves. He stated bluntly that if the United States had not helped us, we would not have won the war. If we had had to fight Nazi Germany one on one, we could not have stood up against Germany 's pressure, and we would have lost the war. No one ever discussed this subject officially, and I do n't think Stalin left any written evidence of his opinion, but I will state here that several times in conversations with me he noted that these were the actual circumstances. He never made a special point of holding a conversation on the subject, but when we were engaged in some kind of relaxed conversation, going over international questions of the past and present, and when we would return to the subject of the path we had traveled during the war, that is what he said. When I listened to his remarks, I was fully in agreement with him, and today I am even more so. In a confidential interview with the wartime correspondent Konstantin Simonov, the famous Soviet Marshal G.K. Zhukov is quoted as saying : Today ( 1963 ) some say the Allies did n't really help us... But listen, one can not deny that the Americans shipped over to us material without which we could not have equipped our armies held in reserve or been able to continue the war. Returning goods after the war Roosevelt, eager to ensure public consent for this controversial plan, explained to the public and the press that his plan was comparable to one neighbor 's lending another a garden hose to put out a fire in his home. `` What do I do in such a crisis ? '' the president asked at a press conference. `` I do n't say... ' Neighbor, my garden hose cost me $15 ; you have to pay me $15 for it '... I do n't want $15 -- I want my garden hose back after the fire is over. '' To which Senator Robert Taft ( R - Ohio ), responded : `` Lending war equipment is a good deal like lending chewing gum. You do n't want it back. '' In practice, very little was returned except for a few ships. Since the Lend - Lease agreement did not provide any practical mechanism for allied nations to make good on any materials or equipment destroyed in the war, the United States government was in fact implicitly conceding that it did not expect the return of every piece of material and equipment that it was loaning to its allies. Any suggestion otherwise in the part of the administration was intended more as political rhetoric to keep public opinion favorable as opposed to serious foreign policy. The intended and actual commitment the United States expected from its allies was to prevent the conflict from reaching the North American continent, which helped to ensure that the United States would be the world 's strongest and most prosperous industrial power by the end of the war. Joseph Stalin, during the Tehran Conference during 1943, acknowledged publicly the importance of American efforts during a dinner at the conference : `` Without American production the United Nations ( the Allies ) could never have won the war.

The Lend - Lease Memorial in Fairbanks, Alaska commemorates the shipment of U.S. aircraft to the Soviet Union along the Northwest Staging Route. American deliveries to the Soviet Union can be divided into the following phases : `` pre Lend - lease '' 22 June 1941 to 30 September 1941 ( paid for in gold and other minerals ) first protocol period from 1 October 1941 to 30 June 1942 ( signed 7 October 1941 ), these supplies were to be manufactured and delivered by the UK with US credit financing. second protocol period from 1 July 1942 to 30 June 1943 ( signed 6 October 1942 ) third protocol period from 1 July 1943 to 30 June 1944 ( signed 19 October 1943 ) fourth protocol period from 1 July 1944, ( signed 17 April 1945 ), formally ended 12 May 1945 but deliveries continued for the duration of the war with Japan ( which the Soviet Union entered on the 8 August 1945 ) under the `` Milepost '' agreement until 2 September 1945 when Japan capitulated. On 20 September 1945 all Lend - Lease to the Soviet Union was terminated. Delivery was via the Arctic Convoys, the Persian Corridor, and the Pacific Route. The Arctic route was the shortest and most direct route for lend - lease aid to the USSR, though it was also the most dangerous as it involved sailing past German - occupied Norway. Some 3,964,000 tons of goods were shipped by the Arctic route ; 7 % was lost, while 93 % arrived safely. This constituted some 23 % of the total aid to the USSR during the war. The Persian Corridor was the longest route, and was not fully operational until mid-1942. Thereafter it saw the passage of 4,160,000 tons of goods, 27 % of the total. BM - 13N Katyusha on a Lend - Lease Studebaker US6 truck, at the Museum of the Great Patriotic War, Moscow. The Pacific Route opened in August 1941, but was affected by the start of hostilities between Japan and the US ; after December 1941, only Soviet ships could be used, and, as Japan and the USSR observed a strict neutrality towards each other, only non-military goods could be transported. Nevertheless, some 8,244,000 tons of goods went by this route, 50 % of the total. In total, the U.S. deliveries through Lend - Lease amounted to $11 billion in materials : over 400,000 jeeps and trucks ; 12,000 armored vehicles ( including 7,000 tanks, about 1,386 of which were M3 Lees and 4,102 M4 Shermans ) ; 11,400 aircraft ( 4,719 of which were Bell P - 39 Airacobras ) and 1.75 million tons of food. Roughly 17.5 million tons of military equipment, vehicles, industrial supplies, and food were shipped from the Western Hemisphere to the USSR, 94 % coming from the US. For comparison, a total of 22 million tons landed in Europe to supply American forces from January 1942 to May 1945. It has been estimated that American deliveries to the USSR through the Persian Corridor alone were sufficient, by US Army standards, to maintain sixty combat divisions in the line. The United States delivered to the Soviet Union from October 1, 1941 to May 31, 1945 the following : 427,284 trucks, 13,303 combat vehicles, 35,170 motorcycles, 2,328 ordnance service vehicles, 2,670,371 tons of petroleum products ( gasoline and oil ) or 57.8 percent of the High - octane aviation fuel, 4,478,116 tons of foodstuffs ( canned meats, sugar, flour, salt, etc. ), 1,911 steam locomotives, 66 Diesel locomotives, 9,920 flat cars, 1,000 dump cars, 120 tank cars, and 35 heavy machinery cars. Provided ordnance goods ( ammunition, artillery shells, mines, assorted explosives ) amounted to 53 percent of total domestic production. One item typical of many was a tire plant that was lifted bodily from the Ford Company 's River Rouge Plant and transferred to the USSR. The 1947 money value of the supplies and services amounted to about eleven billion dollars. British deliveries to the Soviet Union Red Army in Bucharest near Boulevard of Carol I. with British - supplied Universal Carrier. A Valentine tank destined for the Soviet Union leaves the factory in Britain. In June 1941, within weeks of the German invasion of the USSR, the first British aid convoy set off along the dangerous Arctic sea route to Murmansk, arriving in September. It carried 40 Hawker Hurricanes along with 550 mechanics and pilots of No. 151 Wing to provide immediate air defence of the port and to train Soviet pilots. The convoy was the first of many convoys to Murmansk and Archangelsk in what became known as the Arctic convoys, the returning ships carried the gold that the USSR was using to pay the US. By the end of 1941, early shipments of Matilda, Valentine and Tetrarch tanks represented only 6.5 % of total Soviet tank production but over 25 % of medium and heavy tanks produced for the Red Army. The British tanks first saw action with the 138 Independent Tank Battalion in the Volga Reservoir on 20 November 1941. Lend - Lease tanks constituted 30 to 40 percent of heavy and medium tank strength before Moscow at the beginning of December 1941. British Mk III ' Valentine ' destroyed in the Soviet Union, January 1944. Significant numbers of British Churchill, Matilda and Valentine tanks were shipped to the USSR. Between June 1941 and May 1945, Britain delivered to the USSR : 3,000 + Hurricanes 4,000 + other aircraft 27 naval vessels 5,218 tanks ( including 1,380 Valentines from Canada ) 5,000 + anti-tank guns 4,020 ambulances and trucks 323 machinery trucks 1,212 Universal Carriers and Loyd Carriers ( with another 1,348 from Canada ) 1,721 motorcycles £ 1.15 bn worth of aircraft engines 1,474 radar sets 4,338 radio sets 600 naval radar and sonar sets Hundreds of naval guns 15 million pairs of boots In total 4 million tonnes of war material including food and medical supplies were delivered. The munitions totaled £ 308m ( not including naval munitions supplied ), the food and raw materials totaled £ 120m in 1946 index. In accordance with the Anglo - Soviet Military Supplies Agreement of 27 June 1942, military aid sent from Britain to the Soviet Union during the war was entirely free of charge. Reverse Lend - Lease Reverse Lend - lease was the supply of equipment and services to the United States. Nearly $8 billion ( equivalent to $124 billion today ) worth of war material was provided to U.S. forces by her allies, 90 % of this sum coming from the British Empire. Reciprocal contributions included the Austin K2 / Y military ambulance, British aviation spark plugs used in B - 17 Flying Fortresses, Canadian - made Fairmile launches used in anti-submarine warfare, Mosquito photo - reconnaissance aircraft, and Indian petroleum products. Australia and New Zealand supplied the bulk of foodstuffs to United States forces in the South Pacific. Though diminutive in comparison, Soviet - supplied reverse lend - lease included 300,000 metric tons of chromium and 32,000 metric tons of manganese ore, as well as wood, gold and platinum. In a November 1943 report to Congress, President Roosevelt said of Allied participation in reverse Lend - lease :... the expenditures made by the British Commonwealth of Nations for reverse lend - lease aid furnished to the United States, and of the expansion of this program so as to include exports of materials and foodstuffs for the account of United States agencies from the United Kingdom and the British colonies, emphasizes the contribution which the British Commonwealth has made to the defense of the United States while taking its place on the battle fronts. It is an indication of the extent to which the British have been able to pool their resources with ours so that the needed weapon may be in the hands of that soldier -- whatever may be his nationality - who can at the proper moment use it most effectively to defeat our common enemies. In 1945 -- 46, the value of Reciprocal Aid from New Zealand exceeded that of Lend - Lease, though in 1942 -- 43, the value of Lend - Lease to New Zealand was much more than that of Reciprocal Aid. Britain also supplied extensive material assistance to American forces stationed in Europe, for example the USAAF was supplied with hundreds of Spitfire Mk V and Mk VIII fighter aircraft. The cooperation that was built up with Canada during the war was an amalgam compounded of diverse elements of which the air and land routes to Alaska, the Canol project, and the CRYSTAL and CRIMSON activities were the most costly in point of effort and funds expended.... The total of defense materials and services that Canada received through lend - lease channels amounted in value to approximately $419,500,000.... Some idea of the scope of economic collaboration can be had from the fact that from the beginning of 1942 through 1945 Canada, on her part, furnished the United States with $1,000,000,000 to $1,250,000,000 in defense materials and services.... Although most of the actual construction of joint defense facilities, except the Alaska Highway and the Canol project, had been carried out by Canada, most of the original cost was borne by the United States. The agreement was that all temporary construction for the use of American forces and all permanent construction required by the United States forces beyond Canadian requirements would be paid for by the United States, and that the cost of all other construction of permanent value would be met by Canada. Although it was not entirely reasonable that Canada should pay for any construction that the Canadian Government considered unnecessary or that did not conform to Canadian requirements, nevertheless considerations of self - respect and national sovereignty led the Canadian Government to suggest a new financial agreement.... The total amount that Canada agreed to pay under the new arrangement came to about $76,800,000, which was some $13,870,000 less than the United States had spent on the facilities. Canadian aid to Britain Main article : Billion Dollar Gift and Mutual Aid Canada had its own version of lend - lease for Britain. Canada gave Britain gifts totaling $3.5 billion during the war, plus a zero - interest loan of $1 billion ; Britain used the money to buy Canadian food and war supplies. Canada also loaned $1.2 billion on a long - term basis to Britain immediately after the war ; these loans were fully repaid in late 2006. The Gander Air Base ( RCAF Station Gander ) located at Gander International Airport built in 1936 in Newfoundland was leased by Britain to Canada for 99 years because of its urgent need for the movement of fighter and bomber aircraft to Britain. The lease became redundant when Newfoundland became Canada 's tenth province in 1949. Most American Lend - Lease aid comprised supplies purchased in the U.S., but Roosevelt allowed Lend - Lease to purchase supplies from Canada, for shipment to Britain, China and Soviet Union. Repayment Main article : Anglo - American loan Congress had not authorized the gift of supplies delivered after the cutoff date, so the U.S. charged for them, usually at a 90 % discount. Large quantities of undelivered goods were in Britain or in transit when Lend - Lease terminated on 2 September 1945. Britain wished to retain some of this equipment in the immediate post war period. In 1946, the post-war Anglo - American loan further indebted Britain to the U.S. Lend - Lease items retained were sold to Britain at 10 % of nominal value, giving an initial loan value of £ 1.075 billion for the Lend - Lease portion of the post-war loans. Payment was to be stretched out over 50 annual payments, starting in 1951 and with five years of deferred payments, at 2 % interest. The final payment of $83.3 million ( £ 42.5 million ), due on 31 December 2006 ( repayment having been deferred in the allowed five years and during a sixth year not allowed ), was made on 29 December 2006 ( the last working day of the year ). After this final payment Britain 's Economic Secretary to the Treasury formally thanked the U.S. for its wartime support. Tacit repayment of Lend - Lease by the British was made in the form of several valuable technologies, including those related to radar, sonar, jet engines, antitank weaponry, rockets, superchargers, gyroscopic gunsights, submarine detection, self - sealing fuel tanks, and plastic explosives as well as the British contribution to the Manhattan Project. Many of these were transferred by the Tizard Mission. The official historian of the Office of Scientific Research and Development, James Phinney Baxter III, wrote : `` When the members of the Tizard Mission brought the cavity magnetron to America in 1940, they carried the most valuable cargo ever brought to our shores. '' While repayment of the interest - free loans was required after the end of the war under the act, in practice the U.S. did not expect to be repaid by the USSR after the war. The U.S. received $2 M in reverse Lend - Lease from the USSR. This was mostly in the form of landing, servicing, and refueling of transport aircraft ; some industrial machinery and rare minerals were sent to the U.S. The U.S. asked for $1.3 B at the cessation of hostilities to settle the debt, but was only offered $170 M by the USSR. The dispute remained unresolved until 1972, when the U.S. accepted an offer from the USSR to repay $722 M linked to grain shipments from the U.S., with the remainder being written off. During the war the USSR provided an unknown number of shipments of rare minerals to the US Treasury as a form of cashless repayment of Lend - Lease. This was agreed upon before the signing of the first protocol on 1 October 1941 and extension of credit. Some of these shipments were intercepted by the Germans. In May 1942, the HMS Edinburgh was sunk while carrying 4.5 tonnes of Soviet gold intended for the U.S. Treasury. This gold was salvaged in 1981 and 1986. In June 1942, the SS Port Nicholson was sunk en route from Halifax, Canada to New York, allegedly with Soviet platinum, gold, and industrial diamonds aboard ; the wreck was discovered in 2008. However, none of this cargo has been salvaged, and no documentation of its treasures has been produced.
