Ford Once Made A Mile-long Factory To Build Bombers Faster Than Anyone Thought Possible

By nan mediate of 1938, Europe had begun inching toward destruction. Adolf Hitler had taken complete Austria, nan opening of Germany's bloody run that would propulsion nan continent into nan chaos of World War II. Across nan Atlantic, U.S. President Franklin D. Roosevelt understood nan request for nan American subject to beryllium prepared for nan coming war, thing nan state had failed to do earlier World War I. He petitioned Congress for 10,000 caller airplanes, a large inquire fixed that nan state was still successful nan throes of nan Great Depression, and nowhere adjacent nan subject powerhouse it is today. Its Army Air Corps classed moreover lower, pinch a meager arsenal of outdated planes.

Congress reached a compromise, approving just complete half of nan requested number of planes to beryllium built complete nan adjacent 5 years. However, nan tide of warfare was successful Germany's favor, and by 1940, nan Nazis had conquered Belgium, France, nan Netherlands, and Luxembourg. It was only a matter of clip earlier nan U.S. would beryllium drawn into nan war, which happened successful December 1941, erstwhile Germany's state Japan attacked Pearl Harbor. Knowing this threat, Roosevelt pushed Congress again, this clip asking for 50,000 planes a year. The task seemed intolerable to many, but by 1944, America was churning retired astir doubly that magnitude of bombers each year.

Roosevelt achieved this feat by turning to an manufacture known to nutrient analyzable machinery connected a ample scale. Automakers are known for their engineering expertise and expertise to nutrient a ample number of components successful a short time. Car companies took to building bombers and weapons. The B-24 Liberator became nan go-to plane due to its long-range ability, making it a formidable plus to woody pinch force forces crossed the Pacific Ocean, arsenic good as Britain's affinity for nan dense bomber successful nan conflict against Germany.

Consolidated Aircraft held nan statement to build B-24 bombers, but its output was thing but businesslike (read painfully slow). The institution built craft outdoors connected makeshift rigs where workers spent hours attaching a azygous engine. 

Ford was 1 of nan carmakers approached to make parts for nan B-24. In early 1941, Ford executive Charles Sorensen visited nan Consolidated mill and was appalled by what he saw. Highly knowledgeable successful nan section of accumulation and assembly, Sorensen sketched a accumulation statement for nan B-24 that nighttime by breaking down nan monolithic bomber into sub-assemblies that could beryllium built for illustration cars connected a moving accumulation line. Ford decided to beryllium much involved. It declared that it would not build B-24 bomber parts; it would build nan full B-24.

In February 1941, nan Army awarded Ford a statement to build B-24 planes, and nan carmaker began building of a monolithic accumulation analyzable westbound of its location base in Detroit. The Willow Run works grew to go nan world's largest factory at nan time. It featured an different 90-degree turn, giving it a unsocial L-shaped layout. It solved 2 problems — avoiding stretching into a planned airdrome and having nan full installation wrong 1 county, which helped prevention connected taxes.

By precocious 1941, and $47 cardinal later, nan Willow Run mill was operational. It was expensive, but not arsenic costly arsenic a $90-million F-35 combatant pitchy crashing consecutive retired of nan factory. Ford moreover built an adjoining airfield truthful that nan bombers, caller disconnected nan assembly line, could beryllium tested for fittingness connected nan runway before being sent to war. Having a Short SC1 vertical-takeoff combatant jet that didn't request a runway would person surely saved Ford money.

To springiness you a standard of nan operation, a B-24 bomber is 66 feet, 4 inches long, pinch a wingspan of 110 feet. The Willow Run factory, meanwhile, spans 3.5 cardinal quadrate feet. To unit this mega factory, nan authorities provided assistance by transporting and lodging overmuch of nan workforce and their families.

The Willow Run mill was a turning constituent for nan aircraft-building industry. It was nan first clip that alternatively of a bomber level being constructed successful 1 place, it was built by sub-assemblies being mated together connected an assembly that stretched for a mile. Construction saw fuselages, wings, and tail sections travel together astatine captious junctions, taking nan style of a bomber arsenic it moved forward. Initially, accumulation was slow. However, arsenic ratio improved, accumulation changeable up arsenic well. By 1944, Ford was making 1 bomber each 63 minutes. At its height, nan Willow Run mill produced 428 bombers successful a azygous month.

It wasn't easy, though. With nary usable blueprints from Consolidated, Ford's engineers had to reverse-engineer thousands of bomber-part drawings earlier an assembly statement could beryllium group up. It came to a constituent wherever engineers were drafting up miles of method schematics each day. Ford guidance had to navigate both nan authorities and Consolidated Aircraft, which still held portion of nan original contract.

Constant creation changes from Consolidated caused hurdles, while legislature investigators recovered that meddling from nan original contractor was causing delays. Eventually, complete power of nan works was handed complete to a azygous works manager, and from past on, accumulation began to stabilize. Once nan reddish portion cleared, Ford's methods began to shine, and Willow Run became nan astir prolificAmerican mill during World War II.

The workforce astatine Willow Run became a awesome of America during nan war. As men were conscripted for war, women filled their places connected nan assembly line. Thousands of women entered nan workforce, taking connected jobs for illustration riveting and spot welding. While immoderate sources conflict this, Ford says nan iconic 'Rosie nan Riveter' poster, which went connected to symbolize women taking connected accepted men's roles and go an iconic portion of popular civilization and nan feminist movement, was inspired by Rose Will Monroe, a worker astatine nan Willow Run plant.  

People from each complete nan U.S. settled successful Michigan, attracted by nan committedness of municipality life and dependable pay. Employment peaked astatine 42,000 earlier tapering disconnected arsenic accumulation ratio improved. Ford utilized each assets disposable to ramp up production. An illustration is utilizing small group to climb wrong nan bomber's wings to clasp parts successful place.

The plant's sheer size meant that managing nan workforce required different solutions. The Willow Run works tract had an on-site hospital and a recreational field, and hordes of buses ferried workers each time from Detroit and surrounding towns. Willow Run wasn't conscionable an business experiment; it was a societal one.

By nan extremity of World War II, nan Willow Run mill had produced complete 8,600 B-24 bombers. Production stopped a fewer months earlier nan warfare ended successful August 1945, but nan B-24 already was connected its past legs earlier that. 

By 1943, nan U.S. subject had already started testing its caller B-29 Superfortress, which offered a agelong range, could transportation a bigger payload, and alert higher successful nan ambiance arsenic well, acknowledgment to a pressurized cabin. For nan time, it astir apt had a cockpit arsenic cool arsenic nan 1 connected nan F-22 Raptor combatant jet. The B-29 was utilized to driblet atomic bombs connected nan Japanese cities of Hiroshima and Nagasaki, starring to Japan's eventual surrender to nan Allies.

The Willow Run mill was yet sold disconnected to different carmakers. Today, a information of it serves arsenic nan Michigan Flight Museum. However, its bequest remains arsenic nan birthplace of mass-produced aircraft. The mile-long mill helped triumph World War II, 1 bomber astatine a time.
