Pre-Dreadnoughts
like these examples from the U.S. Navy were attempts to utilize
the development of smokeless
powder, steel alloys and steam. Before 3-stage re-generation,
steam gave lousy mileage per tonne of coal, so sails were kept,
just in case. By the late 1880's refinement in steam re-generation
allowed their removal. Better, more reliable propulsion systems
showed deficiency in hull design as ships could sail in any
weather with reliable steam—these are not hulls for the angry
North Atlantic.
The Spanish-American war showed the need for better fire control
and aiming, which had remained primitive (the U.S.N. scored less
than 1 hit per 1000 shells against the Spanish at Manila). By 1912
all the first line navies had relatively sophisticated optical
range-finders. The WWI-era Warspite holds the record for
naval gunnery against
a moving target, of 26,500 yards (just over 15
miles), hitting the Italian battleship Giulio Cesare during
the Battle of Calabria, 9 July 1940.
