In 1911,
it was proposed the Navy adopt a 406mm L/40 gun instead of the existing
356mm L/45. This was rejected by Admiral Strauss of the Bureau of Ordonance
on the grounds that the existing gun was sufficently effective. However,
not much later, Strauss proposed a L/45 version of the 406mm gun, which
the General Board accepted, but the Secretary of the Navy, concerned about
yet another increase in battleship tonnage, declined. Nevetheless, the
design was completed, first test-fired in 1914, and was adopted in the
new Maryland class battleships of 1916. Three ships received eight guns
each, eight more were build for the unfinished Washington, and a total
of eight spares were build as well.
