Productivity
in the construction of Liberty Ships.
The graph plots the average across all yards of manhours and construction
time for all ships delivered in a given month.
Construction time of Liberty ships in selected yards. because yards
entered at different times, the average acoss all yards (above) underestimates
the increases in production speed attained by individual yards.
Manhours
per ship for vessels built in new yards. These data are organized by
rounds of the ways. Manhours on the first [second, third, . . ] round of
the way is the average labor requirement for the first [second, third,
. . ] ship built on each way. Note that some other vessel types experienced
declines in labor requirements even more marked than Liberty ships.
