Bombing, materials, housing, and competing priorities constrained Vickers

Why did Vickers lose submarine-building capacity during the war?

Bombing, materials, housing, and the decision to prioritize Vickers for other specialized work all contributed.

Bombing, material shortages, and worker accommodation all constrained submarine output. Opportunity cost mattered as well. Vickers possessed skills needed for other urgent production, so the state deliberately concentrated the company on work it performed especially well.
