The following graphs show the number of merchant ships launched in a particular year plotted against their combined gross registered tonnage GRT divided by 1000 (GRT/100).
Warships are totally excluded from this data because their GRT is either not measured or not generally known. Naval auxiliaries of all types are however included.
Above: Note the steady decline from 1906 to the slump of 1933 and the recovery to the previous trend post WW2
Above: Post WW2 the tonnage output is constant but launches decrease until the virtual collapse of merchant shipbuilding in 1978
