To achieve high production rates, people were specialized. Hopefully I can find similar lists for them, once I know the names. Limited industrial capacity, especially for reduction gears, meant that relatively few of these ships were built. I would like to know how big was the workforce that constructed them? A plan for the first peacetime draft in american history. @DrZ214 Dry-docks are very expensive, and construction time in one correspondingly expensive The faster you can get hulls out of the dry-dock, the less expensive the ship is to build.. Though the work force was largely untrained in the method of welding ships together, it was not worker error that caused these failures.
