U.S.S. Wisconsin (BB-9), 1901

The Wisconsin visits Sydney, Australia in 1908, during the voyage of the Great White Fleet.

The 3-ship Illinois class was still under construction in 1898, going into service in 1900

(Alabama) and 1901. These ships were somewhat unique in the U.S. fleet: in some ways

derivative from the Iowa, in others resembling the British Majestic class. After the sensible

switch from 13" to 12" main guns with the Iowa, the Illinois class reverted to the heavier,

slower-firing 13" guns. Compact in the American tradition at 12,500 tons, these ships had a

raised forecastle deck and a lower quarterdeck; their aft 13" turret sat one deck down

compared to the forward turret.

These ships pioneered a new turret

design which became standard in U.S.

battleships until 1910: a 3-D ellipse with

a chisel-ended slice taken from one of

the narrow ends of the ellipse. The

straight, chisel-shaped surface formed

the turret face; the long gun barrels

poked forth from this heavily-armored,

oblique steel wall (right). This model of

turret remained standard in the U.S.

fleet through the remaining decade of

the pre-dreadnought era. Enlarge

Illinois class ships dispensed with the

intermediate, 8" armament used in the

preceding 3 classes, relying on a

secondary armament of 14 six-inchers

mostly in the central redoubt. With her

big guns, Wisconsin had a range of

almost 7 miles (11 km); at extreme

range, her 6" guns could reach out 10

miles (16 km). These ships had a clean,

uncluttered layout in contrast to most

American designs of the time. Like the

Majestics and some French battleships, they had two side-by-side funnels, leaving a long,

uncluttered boat deck aft. Robustly protected with Krupp cemented (KC) armor -- a first in the

American fleet --, they were on the slow side at 16 knots. These were fair sea boats; all

participated in the globe-girdling voyage of the Atlantic Fleet in 1908-09.

The voyage of the Great White Fleet was significant for more than its bravura PR value. It

taught seamanship and self-reliance among the crews, taught them they could maintain, refuel,

and repair their ships far from base. The trip served as a broad training, developing an

experienced corps of deep-water sailors for the Navy to draw upon.

These anti-TB weapons, a legacy ofpre-dreadnought tradition, had such limited range they

were obsolete by the time the ships went into service.

All these ships were used as training vessels in WWI and immediately afterwards.Alabama and

Wisconsin were scrapped in the early Twenties in conformance with the Washington Treaty for

Naval Disarmament. The Illinois found a useful niche which guaranteed prolonged survival:

she was converted to a a floating armory at New York Navy Yard in 1924 and was assigned to

the New York Naval Reserve. She remained there for more than 30 years, though renamed

Prairie State to free her name for an anticipated Montana-class battleship on January 8, 1941

(the Montana class was never built). During World War II a new Wisconsin joined the fleet: an

Iowa-class battleship (BB-64), the ultimate embodiment of the big-gun ship in the U.S. Navy; a

newAlabama, of the smallerIndiana class, also appeared in the navy's Register; both these

WWII battlewagons are museum ships today. Meanwhile, Prairie State served as a Naval

Reserve Midshipmen Training School at New York (shown below during the 1940s or 50s).

Postwar she was retained on loan to New York State as quarters for a naval reserve unit until

December 31, 1956. Immediately thereafter she was towed to Baltimore and sold to Bethlehem

Steel for scrap.
