Named after
the state of Idaho, the 32,000-ton USS Idaho
(BB-42) was a New Mexico class
battleship that was built by the New York Shipbuilding Corporation at Camden,
NJ, and was commissioned on 24 March 1919. The ship was approximately 624 feet
long and 97 feet wide, had a top speed of 21 knots, and had a crew of 1,081
officers and men. Idaho was armed
with 12 14-inch guns, 22 5-inch guns, eight 3-inch guns, and two 21-inch
torpedo tubes.
After being
commissioned, Idaho steamed to Rio de
Janeiro, Brazil, in July 1919 and then transited the Panama Canal to the
Pacific, where she was based for the next 12 years. During that time, Idaho participated in various naval
exercises and training programs and traveled from the Caribbean to Hawaii and
as far south as Chile. Idaho also
patrolled off the coast of Alaska in 1920 and visited Australia and New Zealand
in 1925. In September 1931, the battleship entered the Norfolk Navy Yard at
Norfolk, Virginia, for an extensive overhaul and modernization, which lasted
more than three years.
After leaving
the Norfolk Navy Yard in October 1934, Idaho’s
appearance had been transformed. Gone were the “cage” masts that were such a
distinguishing feature of American battleships of that era, and a new tower
superstructure supporting modern gunfire control systems had been built. Now
one of the US Navy’s most modern warships, Idaho
returned to the Pacific in 1935 to resume her peacetime duties of preparing for
possible combat.
After World
War II began in Europe in 1939, the US Navy’s attention was diverted towards
the Atlantic. Idaho was transferred
to the Atlantic Fleet in June 1941 and was based in Iceland for much of the
rest of that year. She escorted convoys and protected them against the threat
of German surface raiders during that period of “undeclared war” with Germany.
After the Japanese attacked Pearl Harbor, Hawaii, on 7 December 1941, Idaho was sent back to the Pacific,
arriving there in January 1942. For the next year, Idaho patrolled off America’s west coast and Hawaii. In April 1943,
Idaho was sent north to the Aleutian
Islands, where she supported the American amphibious landings at Attu in May
and Kiska in August.
Idaho then was ordered to the central
Pacific, taking part in the American invasion of the Gilbert Islands in
November 1943 and the invasion of the Marshall Islands in February 1944. She
then participated in the bombardment of New Ireland in March, the invasion of
the Marianas Islands in June and July, and the assault on the Palau Islands in
September. During all of these operations, Idaho
was used as an enormous artillery battery, providing heavy gunfire support for
the American troops on shore.
In February
1945, Idaho bombarded Japanese
targets on Iwo Jima. Her massive guns were then unleashed on enemy positions on
Okinawa from late March to May 1945. While firing at targets on Okinawa, Idaho was damaged by a Japanese
kamikaze, or suicide plane, on 12 April. No crewmen were lost in the attack
and, after going to Guam briefly for repairs, Idaho returned to Okinawa and resumed her gunfire support missions.
