A lot of Liberty Ships were built during WW2. These were fairly large transport ships with a capacity of about 11,000 t deadweight tonnage. Wikipedia says the average build time was 42 days, and that the workforce was newly trained because no one had ever made welded ships before.
I would like to know how big was the workforce that constructed them? In other words, how many people worked on one in the drydock? And were they divided into 3 shifts for round-the-clock work?
I'm just interested in the ship construction. No need to factor in things like engine building at a factory somewhere else.
Edit: Actually, I want the work to build/assemble the ship, both on the slipway and on the water. Before posting this question, I did not know that ships were finished on the water. (I heard of "fitting out" before, but thought that was only stuff like bringing in food and beds and misc. stuff like radios and other small equipment.)
