[3][41], Ford had switched over to the single-tailed B-24N in May 1945, but the end of the war in Europe in the same month brought a rapid end to Liberator production; the contract with Ford was officially terminated on 31 May 1945 and orders for 5168 unbuilt B-24N-FO bombers were cancelled as well. Meanwhile, Ford was savaged in the Detroit press because it took too long. Kaiser-Frazer produced some 739,000 cars at Willow Run between 1947 and 1953, when the company acquired Willys-Overland and moved all operations to the Willys factory in Toledo, Ohio. [7] Indeed, the majority of the plant was demolished in late 2013 and early 2014. That was the schedule six days a week. Out of sheer necessity, Willow Runs 42,500-member He was violently anti-union and there were serious labor difficulties, including a massive strike. Consolidated maintained control over design changes and so did the Army Air Corps (retitled U.S. Army Air Force in June 1941). Sorensen was shocked. Starting with 2,600 acres of Henry Ford's bare farmland, ground was broken on the 3.5 million sq.-ft. facility in April of 1941, and the first B-24 Liberator four-engine bomber flew off the giant Willow Run airfield in September of 1942. [11] The Willow Run plant featured a large turntable two-thirds of the way along the assembly line, allowing the B-24 production line to make a 90 turn before continuing to final assembly. All true, but he didnt mention the hard steel dies he authorized, the same types used to slam auto parts into shape, damaged and defaced the softer aluminum, a metal comprising 85 percent of B-24 content. For Our Members-. Approximately one-third of the plant's assembly line workers were female. [7] The 175,000-square-foot (16,300m2) portion of the original bomber plant that Yankee seeks to preserve is less than 5% of the massive facility, comprises the end of the former B-24 assembly line at the far eastern edge of the property, and contains the two iconic bay doors from which the finished Consolidated B-24 Liberator bombers exited the plant during World War II. The plant initially built components. After the war, these residences served students attending the nearby University of Michigan on the G.I. Warren Avis, a decorated B-24 pilot in the 376th Bombardment Group, opened the nations first airport rental car service in the terminal and grew it into Avis Rent A Car Systems. That hulking plant was idled in the early 1990s, putting about 4,000 people out of work. As American involvement in the war seemed more likely, the U.S. government approached Ford Motor Company about making parts and subassemblies for B-24 bombers. Working with a scale model, they shifted equipment and work stations for maximum efficiency. The water is treated in a modern treatment plant completed in 1939. Between them, there was a shelter for more than 15,000 people, roughly the number of people living in Ypsilanti at the time. While there were many injuries, it is notable that Willow Run did not record a single fatality while the factory was in service. The plant's kitchen prepared nearly 10,000 rolls each day. The company also develops, designs, and manufactures peripherals and components for its products. [48], By the May 1, 2014, deadline, the Yankee Air Museum had raised over $7 million of its original $8 million fundraising goal, which was enough to enable the building's owners to move forward with signing a Purchase Agreement with Yankee, with the actual purchase expected to be finalized in late summer or fall of 2014. heavy aircraft. Simply moving workers to and from the plant was a major logistical challenge. Easements were acquired from landowners across the county line in Ypsilanti Township where the Liberator plant (and eventually the airport terminal) would be built. It appears that Camp Willow Run shut down after the 1941 season with the coming of the bomber plant, many of the boys went to work at the Willow Run village industry plant, and others moved on to the apprentice and trade school. Next WRBP Meeting -. Not given to understatement, he proclaimed that the one-level superstructure would be the most enormous room in the history of man.. It was an attempt to reverse the trend toward ever-increasing weight of the Liberator as more and more armament, equipment, and armor had been added, with no corresponding increase in engine power. Four 1,200-hp Pratt & Whitney R-1830 Twin Wasp engines assembled by Buick Motor Division shook the earth as the newly minted war machines cast aloft on test flights. The main building would be more than a mile long with dual, parallel assembly lines. As he spoke, the country had fewer than 3,000 warplanes in its arsenal, most obsolete. Over the course of the war, the hospital handled more than two million medical cases. The bugs were eventually worked out of the manufacturing processes, and by 1944, Ford was rolling a Liberator off the Willow Run production line every 63 minutes, 24 hours a day, 7 days a week. No one had ever manufactured airplanes on such a scale before. The B-24H differed from earlier B-24s by having a second turret placed in the nose of the aircraft to increase defensive firepower. Thought to be overly ambitious in its scope, the plant hoped to boost bomber production from one aircraft per day to one plane per hour. For government officials, Ford offered significant advantages. [47], Building owner RACER Trust extended the original fundraising deadline (August 1, 2013) a total of three times since the Yankee Air Museum launched its SaveTheBomberPlant.org campaign. By the end of the war, Ford had pushed 8,865 B-24 heavy bombers out the Willow Run doors for the Army . The others, completed in the 1930s, were located in Dearborn, Michigan (site of the Fords' Fair Lane estate); Sudbury, Massachusetts; two in Richmond Hill, Georgia (the Fords' winter home); Macon, Michigan; and Willow Run.

During a January 1941 inspection tour of the Consolidated San Diego plant with Edsel Ford, gentlemanly 45-year-old company president and son of cantankerous autocrat Henry Ford, Sorensen belittled the operations deliberate, labor-intensive procedures. With so many young men drafted into the armed forces, Willow Run's workforce was unusually diverse for its time: African Americans, whites, older people, younger men unable to serve in the military, and -- most notably -- women. Changeovers required onerous delays and costly retooling. Workers at Willow Run built a staggering 8,685 B-24 bombers -- 6,792 complete planes and 1,893 knock-down kits -- by the time the last one was finished on June 28, 1945. restore a piece of the building, about 175,000 square feet. While assembly workers formed the heart of Willow Run's workforce, there were numerous administrative, clerical and support staff members too. [3][4], By autumn 1943, the top leadership role at Willow Run had passed from Charles Sorensen to Mead L. Thirty-eight tons of structural steel, five million bricks, and six months later, the $65-million colossus began churning out parts while equipment was still being installed and roof and walls remained unfinished. Ford would eventually sell its land to the Reconstruction Finance Corporation's Defense Plant Corporation in July 1944, shortly after the Ford farms were transferred to the company's ownership. The Willow Run Expressway also connected with the Detroit Industrial Expressway, built at the same time. Charles Sorensen boasted that Ford would produce B-24s at the rate of one each hour. An unknown number dwelt in the memories of plant foremen. most enormous room in the history of man.. GM also produced vehicles next door at its Willow Run Assembly plant beginning a few years later, in 1959. Sections included center wing, outer wings and wing tips, fuselage, nacelles, flight deck, nose and tail. The plant produced both Kaiser and Frazer models, including the compact Henry J, which with minor differences was also sold through Sears-Roebuck as the Allstate. Along with the B-17, the B-24 formed the backbone of the Allies' air war over Europe. we intend to restore a piece of the building, about 175,000 square feet. Efforts to desegregate Willow Run Lodge and Village and build additional integrated housing were rebuffed by the Detroit Housing Commission and the National Housing Agency,[25] so noted African-American architect Hilyard Robinson was contracted to design an 80-unit community. Now signifying "the arsenal of democracy", at the outset Ford's Willow Run Bomber Plant was nearly a failure. Willow Run stepped up outsourcing of parts production and subassemblies to almost 1,000 Ford factories and independent suppliers while focusing on building B-24s in more predictable designs that minimized shutdowns. For this reason, a series of Air Technical Service Command modification centers were established for the incorporation of these required theater changes into new Liberators following their manufacture and assignments. The factory prompted the creation of the Washtenaw County Health Department and was a key part of America's "arsenal of . A rough-hewn, hard-charging martinet, Cast Iron Charlie played a principal role in conceiving and designing the worlds first moving assembly line at Fords Highland Park plant bordering Detroit. Willow Run ran two nine hour shifts. [36][37], While the planes were being serviced and made ready for overseas movement, personnel for these planes were also being processed. Although Ford had an option to purchase the plant once it was no longer needed for war production, the company declined to exercise it, and ended its association with Willow Run. Handcrafted versions were pressed into service in England, but the San Diego company lacked resources and methods for high-volume production of the largest, most complex airplane ever designed. Pilots, co-pilots, navigators and crew chiefs were assigned as a crew for each aircraft, sleeping on 1,300 cots as they waited for the B-24s to roll off the assembly line. Despite intensive design efforts led by Ford production executive Charles E. Sorensen,[30] the opening of the plant still saw some mismanagement and bungling, and quality was uneven for some time. Some 12,000 women worked at the Willow Run bomber plant, each paid the same 85 cents an . Although officially retired, Henry Ford still had a say in the company's affairs and refused government financing for Willow Run, preferring to have his company build the factory and sell it to the government, which would lease it back to the company for the duration of the war. Bill. the end of the assembly line where 8700 b-24s rolled out. Ford had no say in the matter; production chaos ensued. The 1st CC was responsible for completing the organization and equipment of tactical and combat bombardment squadrons prior to their deployment to the overseas combat theaters. This made the farmers dislike the plant and its employees because the farmers viewed Willow Run and its employees as attempting to change the established community. In November 2016, RACER Trust sold Willow Run to an entity created by the State of Michigan, which leases the property to the American Center for Mobility (AMC).[9]. The chosen site was farmland owned by Henry Ford on the eastern edge of Michigan's Washtenaw County, near a creek called Willow Run. By the end of the war, Ford had pushed 8,865 B-24 heavy bombers out the Willow Run doors for the Army . 550 sizes, and it weighed 18 tons.

A ghostly, decaying reminder of the industrial and military history echoing within its cavernous expanse, Willow Run was demolished in 2014. [36][38], Once production began, it became difficult to introduce changes dictated by field experience in the various overseas theaters onto the production line in a timely fashion. Crew size was up to ten, and range was up to 3,000 miles. Public bus lines offered 35 daily trips from Detroit, while private carriers offered 130. In on-site classrooms, newly hired workers sat through orientation lectures on the aircraft industry in general, the B-24's specific importance to the war, and the dire consequences should the Allies lose the fight. Up to 8,000 students per week completed training and reported for work. The first Ford-built Liberator rolled off the Willow Run line in September 1942; the first series of Willow Run Liberators was the B-24E.

Employees Assembling Bomber at Willow Run Plant, March 1943, Employees Assembling Bomber at Willow Run Plant, March 1943 / back. Kaiser also built two C-123 Provider airframes at Willow Run, which were scrapped before delivery, as a procurement scandal involving the company put an end to any chance for future Air Force contracts. The first Ford-built Liberator rolled off the Willow Run line in September 1942; the first series of Willow Run Liberators was the B-24E. Hundreds bought their first pair of shoes upon arrival. Perhaps the most impressive breakthrough at Willow Run was Ford's technique for assembling the B-24's center wing section. plant, each paid the same 85 cents an hour as their Production steadily increased, reaching the magical plane-per-hour pinnacle in mid-1944 while accounting for half of all B-24s assembled that year. The Willow Run plant was formally dedicated on October 22, 1941, in a ceremony attended by Major Jimmy Doolittle of the U.S. Army Air Forces. Ford proved them wrong, not easily nor entirely, during a 2.5-year production run in a 3.5-million-square-foot factory built over Willow Run Creek near Ypsilanti, MI. Following the success of the Save the Bomber Plant campaign, the Museum purchased a portion of the Willow Run Bomber Plant that produced B-24 Liberators during World War Two.

Sorensen protested that Willow Run could not function under these strictures. Automobiles of the era had 15,000 parts and weighed around 3,000 pounds. The salvaged Hydramatic transmission tooling and machinery relocated to Willow Run and were back in production just nine weeks after the fire.[43]. But no project captured the public's imagination like Willow Run, where Ford Motor Company built one B-24 Liberator airplane every 63 minutes. The automaker had . Ford created a permanent jig into which wings could be moved in and out by overhead crane. Well build the whole plane or nothing, Sorensen barked, accompanied by the audacious claim that Ford would assemble new B-24s every hour. Part of the airport complex operated at various times as a research facility affiliated with the University of Michigan, and as a secondary United States Air Force Installation. Construction on the Willow Run Bomber Plant began that spring and it soon became the largest factory under one roof in the world. There was no sequence or orderly flow of materials, no sense of forward motion, no reliance on machined parts, he said.

He went on to oversee operations at the companys River Rouge complex where 100,000 workers could produce 10,000 cars a day, from raw materials to finished products. For the next six months, Sorensen shuttled 70-man teams of engineers and draftsmen back and forth on 2,300-mile trips from Ford headquarters to the Consolidated works in San Diego to immerse themselves in B-24 design, engineering, parts and components. At the request of the government, Ford began to decentralize operations and many parts were assembled at other Ford plants as well as by the company's sub-contractors, with the Willow Run plant concentrating on final aircraft assembly. Frank B. Woodford, 'Willow Run Poses Problems,' New York Times, 19 April 1942, E10; Glenn H.

The delivery of seven YB-24Ns by Ford in June 1945 marked the end of Liberator production at Willow Run.[3][42]. [15] Ford Motor was to have first option on the plant after war production ended, an option it ultimately chose not to exercise, although a rumor in Drew Pearson's syndicated column had Ford planning a postwar use as a tractor factory,[16] but that never came to pass. [3][4] The Birmingham Air Depot's primary mission was modifying Liberators from Willow Run. Design, CMS, Hosting & Web Development :: ePublishing. The plant was originally designed to be able to continue to operate if parts of it were ever bombedwhich resulted in dedicated water, compressed air and gas lines to different areas of the building.". All Rights Reserved BNP Media. Overhead cranes would hoist completed sections onto the final assembly line for joining into a finished aircraft, the same way cars were put together, but on a grand scale in a massive new plant. Because of the many structural changes required to accommodate the nose turret, the first B-24Hs were delivered slightly behind schedule, with the first machines rolling off the production lines at Ford in late June 1943. The center includes a proving ground where smart cars react instantly to all manner of potentially dangerous and problematic situations. Five main contractors hurried the project along, and parts of the plant began production in September 1941.

The team developed the B-24's build sequence from these divisions. Automatic flushing toilets in numerous bathrooms throughout the building didn't stop. Sorensen, Edsel Ford and Henry Ford well understood the difficulties in precision mass production. Established aircraft manufacturers, used to a much slower rate, considered the claim preposterous. male counterparts. Winston Churchill called his specially outfitted B-24 the Commando. The U.S. government contributed $200 million to the project.Originally 975 acres of farmland owned by Henry Ford, the site was developed by the Ford Motor Company into Willow Run ran two nine-hour shifts. [17], Architect Albert Kahn designed the main structure of the Willow Run bomber plant, which had 3,500,000 square feet (330,000m2) of factory space, and an aircraft assembly line over a mile (1600m) long. '"[31], A 1943 committee authorized by Congress to examine problems at the plant issued a highly critical report; the Ford Motor Company had created a production line that too closely resembled an automobile assembly line "despite the warning of many experienced aircraftmen."[32]. This section was known as Willow Run Village. Sixty-seven feet long, the B-24 had 450,000 parts and 360,000 rivets in Workers on the factory floor could purchase meals from lunch wagons that traveled the facility. Since 1992, it has been home to the Yankee Air Museum. Here is his description of the visit and how he conceived the Willow Run bomber plant that eventually manufactured 8,800 of these aircraft. The Yankee Air Museum was able to gain control of approximately 144,900 square feet of the plant,[54] and plans to develop a permanent home for the museum. The 60-year-old production czar viewed mass production of B-24s as the crowning achievement of his career. Employees at Willow Run celebrated the completion of their 6,000th airplane in September 1944. The metal entry doors were also fashioned with magnets to effectively keep the door shut. Blacks and other minorities were welcomed and so were immigrants. [23] The flat-tops contained four, six, or eight apartments with one, two, or three bedrooms. Some 2,500 were parked in an Arizona desert awaiting the day when their aluminum skin and innards would be smelted into ingots for production of coffee percolators, toasters, pots and pans, and myriad other consumer and industrial products to satisfy the ravenous maw of Americas peacetime economy. But just when that milestone seemed possible, the government drastically cut its order for B-24s. His sketches embraced the two fundamentals of mass production: standardized, interchangeable parts and continuous, orderly flow punctuated by stops at assembly stations where workers and machines performed repetitive tasks. No two were alike.. The massive plant turned out 8,645 Liberators vs. 9,808 manufactured by four factories of Consolidated, Douglas Aircraft, and North American Aviation. Some riveted parts were replaced with cast pieces to simplify and speed their manufacture.
