Eagle Class Patrol Craft - Construction

Construction

Ford's plan for building the ships was revolutionary. Establishing a new plant on the River Rouge on the outskirts of Detroit, he proposed to turn them out as factory products, using mass production techniques, and employing factory workers. He would then send the boats by the Great Lakes and the St. Lawrence River to the Atlantic coast. However, Ford had little part in the design of the boats. Except for his insistence upon simple plans and the use of steam turbines, he contributed little of a fundamental nature to the design concept.

The assembly plant was completed in five months, and the first keel was laid in May 1918. The machinery and fittings were largely built at Ford's Highland Park plant in Detroit. At first, Ford believed that boats could be sent down a continuously moving assembly line like automobiles. The size of the craft made this too difficult, however, and a "step-by-step" movement was instituted on the 1,700-foot (520 m) line. The first Eagle boat was launched on 11 July. The launching of these 200-foot (61 m) craft was a formidable operation. Not built on ways from which they could slide into the water, the hulls moved slowly from the assembly line on enormous, tractor-drawn flatcars. They were then placed on a 225-foot (69 m) steel trestle alongside the water's edge which could be sunk 20 feet (6.1 m) into the water by hydraulic action.

The original contract called for delivery of 100 ships by 1 December 1918. Although the first seven boats were completed on schedule, succeeding ones did not follow as rapidly, even though the labor force reached 4,380 by July and later peaked at 8,000. The chief reasons were Ford's excessive initial optimism and the inexperience of labor and supervisory personnel in shipbuilding. Upon the signing of the Armistice in November 1918, the number under contract, previously raised from 100 to 112, was cut to 60. Of these, seven were commissioned in 1918, and the remaining 53 were commissioned in 1919.

The entire Eagle Boat operation came briefly under challenge by Senator Henry Cabot Lodge of Massachusetts in December 1918. At the ensuing Congressional hearings, Navy officials successfully defended the boats as being a necessary experiment and well made while Ford profits were proved to be modest.
