Of course they didn’t own the factories but they took over production. Ford was not allowed to build cars regardless of how much profit could be made.
Henry Ford: Helped Lead American World War II Production Efforts | HistoryNet
"Ford, a known pacifist, opposed America’s entry into World War II. Nevertheless, he agreed to build airplane engines for the British government. In May 1940, he stated: ‘If it became necessary, the Ford Motor Company could, with the counsel of men like [Charles] Lindbergh and [Eddie] Rickenbacker, under our own supervision and
without meddling by government agencies, swing into the production of a thousand airplanes of standard design a day.’
"It was the Japanese attack on Pearl Harbor that inspired Ford to begin a tremendous, all-out manufacturing effort. To the west of Dearborn, the giant Willow Run plant was built to produce B-24 Liberator bombers on an assembly line that was a mile long. The first bomber rolled off the line in May 1942, beginning the effective production of several hundred aircraft a month. Bombers were produced at the rate of one plane per hour, thereby confounding Ford’s critics, who had called the plant undertaking ‘Willit Run.’ By the end of the war, Ford had built 86,865 complete aircraft, plus 57,851 airplane engines, thousands of engine superchargers and generators, and 4,291 military gliders.
"Ford also turned out tanks, armored cars, jeeps and engines for robot bombs. In the midst of the heaviest production during the war years, Ford returned to his post as chief executive of the Ford Motor Company when Edsel, who had taken over for his father, died in 1943.
"Months earlier, Ford’s plants in Great Britain and Canada had joined the production efforts of the United States and poured forth everything from mobile canteens to four-wheel-drive trucks and autos, grenades, bombs and engine-powered landing craft. The U.S. plants were the prime movers in the development of the famous Willys-originated jeep."
