At the start of the pre-dreadnought era the US
Navy was small, weak and generally obsolete; by the end of the
era it was one of the world's major naval forces. The design of
US pre-dreadnoughts paralleled this shift in role and position,
going from small, weak and outdated ships to large, powerful and
modern ships. However, US pre-dreadnoughts were generally a bit
behind foreign ships in adopting new advances. The last class of
pre-dreadnoughts was completed after HMS Dreadnought had
entered service, rendering them instantly obsolete.
A few of the early pre-dreadnought saw service
during the Spanish-American War, and performed well during
terribly one-sided battles. However, the engagements showed that
much better fire control was needed, as hit percentages were
pitifully low.
Aside from the Spanish-American War engagements,
US pre-dreadnoughts saw no combat. They spent much of their time
in reserve or mobilization fleets, and as training ships. In
1907-1909 most of the pre-dreadnoughts then in service, except
the earliest (least-seaworthy) ships, participated in the round
the world cruise of the Great White Fleet. Ships cruising with
the Fleet were Kearsarge, Kentucky, Illinois, Alabama, Maine,
Missouri, Ohio, Virginia, Georgia, New Jersey, Rhode Island,
Connecticut, Louisiana, Vermont, Minnesota and Kansas.
It had been intended that Nebraska, Wisconsin, Mississippi
and Idaho would join the Fleet in 1908, giving a total
force of 20 ships. However, the latter pair of ships was found
to be deficient and thus did not cruise with the Fleet. Nebraska
and Wisconsin did join the cruise, but Alabama and
Maine had developed problems and were forced to drop out
when the additional ships joined.
In 1909-1911 the entire pre-dreadnought fleet
was put through a modernization program, to make the
already-obsolete ships as useful as possible. They received new
cage masts in place of their military pole masts,
superstructures were reduced to a bare minimum, conning towers
were enlarged, new fire controls were fitted, the secondary
batteries reduced, and safety improvements were made in the main
turrets. In addition the fleet was repainted from white-and-buff
to plain gray.
During WWI these ships served mainly as training
ships, operating primarily in the Chesapeake Bay area. They also
conducted a limited number of convoy escort missions. During the
war their secondary batteries were greatly reduced or even
removed entirely, both to improve seaworthiness by removing
low-level casemates, and to provide guns for merchant ships.
Postwar they were assigned to the Cruiser-Transport Force and
outfitted as troop transports to bring troops home from Europe.
All pre-dreadnoughts surviving into the 1920's
were stricken and scrapped under the terms of the Washington
Treaty.
