USS Yorktown (CV-5) was an aircraft carrier that served in the United States Navy during World War II. Named after the Battle of Yorktown in 1781, she was commissioned in 1937. Yorktown was the lead ship of the Yorktown class, which was designed on the basis of lessons learned from operations with the converted battlecruisers of the Lexington class and the smaller purpose-built USS Ranger.
USS California (BB-44) was the second of two Tennessee-class battleships built for the United States Navy between her keel laying in October 1916 and her commissioning in August 1921. The Tennessee class was part of the standard series of twelve battleships built in the 1910s and 1920s, and were developments of the preceding New Mexico class. They were armed with a battery of twelve 14-inch (356 mm) guns in four three-gun turrets. California served as the flagship of the Battle Fleet in the Pacific Ocean for the duration of her peacetime career. She spent the 1920s and 1930s participating in routine fleet training exercises, including the annual Fleet Problems, and cruises around the Americas and further abroad, such as a goodwill visit to Australia and New Zealand in 1925.
USS Lexington (CV-2), nicknamed "Lady Lex", was the name ship of her class of two aircraft carriers built for the United States Navy during the 1920s. Originally designed as a battlecruiser, she was converted into one of the Navy's first aircraft carriers during construction to comply with the terms of the Washington Naval Treaty of 1922, which essentially terminated all new battleship and battlecruiser construction. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. Lexington and her sister ship, Saratoga, were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these included successfully staged surprise attacks on Pearl Harbor, Hawaii. The ship's turbo-electric propulsion system allowed her to supplement the electrical supply of Tacoma, Washington, during a drought in late 1929 to early 1930. She also delivered medical personnel and relief supplies to Managua, Nicaragua, after an earthquake in 1931.
USS Hornet (CV-8), the seventh U.S. Navy vessel of that name, was a Yorktown-class aircraft carrier of the United States Navy.
USS Wasp (CV-7) was a United States Navy aircraft carrier commissioned in 1940 and lost in action in 1942. She was the eighth ship named USS Wasp, and the sole ship of a class built to use up the remaining tonnage allowed to the U.S. for aircraft carriers under the treaties of the time. As a reduced-size version of the Yorktown-class aircraft carrier hull, Wasp was more vulnerable than other United States aircraft carriers available at the opening of hostilities. Wasp was initially employed in the Atlantic campaign, where Axis naval forces were perceived as less capable of inflicting decisive damage. After supporting the occupation of Iceland in 1941, Wasp joined the British Home Fleet in April 1942 and twice ferried British fighter aircraft to Malta.
Clifton Albert Frederick "Ziggy" Sprague was a World War II–era officer in the United States Navy.
USS Pensacola (CL/CA-24) was a cruiser of the United States Navy that was in service from 1929 to 1945. She was the lead ship of the Pensacola class, which the Navy classified as light cruisers in 1929, with the Pensacola herself originally designated as "CL-24." Under the terms of the Washington Naval Treaty, from 1931 on the class was re-classified as heavy cruisers, with the Pensacola being re-designated as "CA-24." The third Navy ship to be named after the city of Pensacola, Florida, she was nicknamed the "Grey Ghost" by Tokyo Rose. She received 13 battle stars for her service.
The Yorktown class was a class of three aircraft carriers built for the United States Navy and completed shortly before World War II, the Yorktown (CV-5), Enterprise (CV-6), and Hornet (CV-8). They immediately followed Ranger, the first U.S. aircraft carrier built as such, and benefited in design from experience with Ranger and the earlier Lexington class, which were conversions into carriers of two battlecruisers that were to be scrapped to comply with the Washington Naval Treaty, an arms limitation accord.
USS Monssen (DD-436), a Gleaves-class destroyer, was the first ship of the United States Navy to be named for Mons Monssen, who was awarded the Medal of Honor for his actions aboard USS Missouri (BB-11) in 1904. Commissioned in 1941, the destroyer saw service during World War II in both Atlantic and Pacific Oceans. Monssen was sunk at the Naval Battle of Guadalcanal on 13 November 1942.
The third USS Worden (DD-352) was a Farragut-class destroyer in the United States Navy during World War II. She was named for John Lorimer Worden.
The National Museum of the United States Navy, or U.S. Navy Museum for short, is the flagship museum of the United States Navy and is located in the former Breech Mechanism Shop of the old Naval Gun Factory on the grounds of the Washington Navy Yard in Washington, D.C., United States.
Vice Admiral Charles Adams Blakely was an officer in the United States Navy during World War I and the interwar period.
William Bowen Ault was a commander in the United States Navy during World War II and a posthumous recipient of the Navy Cross. The front page of the June 18, 1942, issue of the Enterprise Chieftain carries the news of Commander William Ault's death in the Pacific.
The 5"/25 caliber gun entered service as the standard heavy anti-aircraft (AA) gun for United States Washington Naval Treaty cruisers commissioned in the 1920s and 1930s. The goal of the 5"/25 design was to produce a heavy AA gun that was light enough to be rapidly trained manually. The gun was also mounted on pre-World War II battleships and aircraft carriers until replaced by the standard widespread dual-purpose 5"/38 caliber gun, which was derived from the 5"/25. Guns removed from battleships were probably converted for submarine use by late 1943, while a purpose-built variant for submarines was available in mid-1944, and was widely used by them. United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 25 calibers long. It is referred to sometimes as a dual-purpose gun and sometimes as an anti-aircraft gun, because of its comparative weakness against surface targets.
The XAF was an experimental radar set constructed in 1938, which survived World War II as a historical artifact, and is now placed on exhibit at the National Electronics Museum, located in Linthicum, Maryland.
USS Webster (ARV-2) was a Chourre-class aircraft repair ship aircraft repair ship that saw service in the United States Navy during World War II.
AN/SPS-6 is a two-dimensional radar manufactured by Bendix and Westinghouse Electric. It was used by the US Navy as a first-generation air-search radar after World War II, and was widely exported to allies. In addition, the improved AN/SPS-12 is the derivative types developed in other countries.
SK was an American-made air-search radar used during World War II by the United States Navy. Models included SK-1, SK-2 and SK-3.
SM was an American made fighter-direction radar used for the ship ground-controlled interception (GCI) during World War II by the United States Navy. Variation included the SM-1.
