CV-3
USS ''Saratoga'' (CV-3) was a 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 Washington Naval Treaty of 1922. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. ''Saratoga'' and her sister ship, , were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these exercises included successful surprise attacks on Pearl Harbor, Hawaii. She was one of three prewar US fleet aircraft carriers, along with and , to serve throughout World War II. Shortly after the Japanese attack on Pearl Harbor, ''Saratoga'' was the centerpiece of the unsuccessful American effort to relieve Wake Island and was torpedoed by a Japanese submarine a few weeks later. After lengthy repairs, the ship supported forces participating in the Guadalcanal C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Crossroads
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity in July 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945. The purpose of the tests was to investigate the effect of nuclear weapons on warships. The Crossroads tests were the first of many nuclear tests held in the Marshall Islands, and the first to be publicly announced beforehand and observed by an invited audience, including a large press corps. They were conducted by Joint Army/Navy Task Force One, headed by Vice Admiral William H. P. Blandy rather than by the Manhattan Project, which had developed nuclear weapons during World War II. A fleet of 95 target ships was assembled in Bikini Lagoon and hit with two detonations of Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki in 1945, each with a yield of .

8"/55 Caliber Gun
The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navy heavy cruisers and two early aircraft carriers. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 36.6 feet or 11 meters). Mark 9 These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. A down-swing Welin breech block was closed by compressed air from the gas ejector system. Loading with two silk bags each containing of smokeless powder gave a projectile a velocity of 2800 feet per second (853 m/s). Range was 18 miles at the maximum elevation of 41 degrees. Mark 12 These simplified built-up guns eliminated hoops to reduce weight to 17 tons. The breech mechanism was similar and loading two silk bags each containing 43 pounds (20 kg) of smokeless powder gave a 335-pound (152&nb ...

Battle Of Saratoga
The Battles of Saratoga (September 19 and October 7, 1777) marked the climax of the Saratoga campaign, giving a decisive victory to the Americans over the British in the American Revolutionary War. British General John Burgoyne led an invasion army of 7,200–8,000 men southward from Canada in the Champlain Valley, hoping to meet a similar British force marching northward from New York City and another British force marching eastward from Lake Ontario; the goal was to take Albany, New York. The southern and western forces never arrived, and Burgoyne was surrounded by American forces in upstate New York short of his goal. He fought two battles which took place 18 days apart on the same ground south of Saratoga, New York. He gained a victory in the first battle despite being outnumbered, but lost the second battle after the Americans returned with an even larger force. Burgoyne found himself trapped by much larger American forces with no relief, so he retreated to Saratoga (now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Eastern Solomons
The naval Battle of the Eastern Solomons (also known as the Battle of the Stewart Islands and, in Japanese sources, as the Second Battle of the Solomon Sea) took place on 24–25 August 1942, and was the third carrier battle of the Pacific campaign of World War II and the second major engagement fought between the United States Navy and the Imperial Japanese Navy during the Guadalcanal campaign. As at the Battle of the Coral Sea and the Battle of Midway, the ships of the two adversaries were never within sight of each other. Instead, all attacks were carried out by carrier-based or land-based aircraft. After several damaging air attacks, the naval surface combatants from both America and Japan withdrew from the battle area. Although neither side secured a clear victory, the U.S. and its allies gained a tactical and strategic advantage. Japan's losses were greater and included dozens of aircraft and their experienced aircrews. Also, Japanese reinforcements intended for G ...

Guadalcanal Campaign
The Guadalcanal campaign, also known as the Battle of Guadalcanal and codenamed Operation Watchtower by American forces, was a military campaign fought between 7 August 1942 and 9 February 1943 on and around the island of Guadalcanal in the Pacific theater of World War II. It was the first major land offensive by Allied forces against the Empire of Japan. On 7 August 1942, Allied forces, predominantly United States Marines, landed on Guadalcanal, Tulagi, and Florida in the southern Solomon Islands, with the objective of using Guadalcanal and Tulagi as bases in supporting a campaign to eventually capture or neutralize the major Japanese base at Rabaul on New Britain. The Japanese defenders, who had occupied those islands since May 1942, were outnumbered and overwhelmed by the Allies, who captured Tulagi and Florida, as well as the airfield – later named Henderson Field – that was under construction on Guadalcanal. Surprised by the Allied offensive, the Japanese made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Wake Island
The Battle of Wake Island was a battle of the Pacific campaign of World War II, fought on Wake Island. The assault began simultaneously with the attack on Pearl Harbor naval and air bases in Hawaii on the morning of 8 December 1941 (7 December in Hawaii), and ended on 23 December, with the surrender of American forces to the Empire of Japan. It was fought on and around the atoll formed by Wake Island and its minor islets of Peale and Wilkes Islands by the air, land, and naval forces of the Japanese Empire against those of the United States, with Marines playing a prominent role on both sides. The island was held by the Japanese for the duration of the Pacific War theater of World War II; the remaining Japanese garrison on the island surrendered to a detachment of United States Marines on 4 September 1945, after the earlier surrender on 2 September 1945 on the battleship in Tokyo Bay to General Douglas MacArthur.

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

United States Pacific Fleet
The United States Pacific Fleet (USPACFLT) is a theater-level component command of the United States Navy, located in the Pacific Ocean. It provides naval forces to the Indo-Pacific Command. Fleet headquarters is at Joint Base Pearl Harbor–Hickam, Hawaii, with large secondary facilities at Naval Air Station North Island, California. Origins A Pacific Fleet was created in 1907 when the Asiatic Squadron and the Pacific Squadron were combined. In 1910, the ships of the First Squadron were organized back into a separate Asiatic Fleet. The General Order 94 of 6 December 1922 organized the United States Fleet, with the Battle Force as the Pacific presence. Until May 1940, the Battle Force was stationed on the West Coast of the United States. Headquarters, battleships, aircraft carriers and heavy cruisers were stationed at San Pedro close to the Long Beach Naval Shipyard. Light cruisers, destroyers and submarines were stationed at San Diego. During the summer of that year, as pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battlecruiser
The battlecruiser (also written as battle cruiser or battle-cruiser) was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour (to a varying degree) and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bougainville Campaign
The Bougainville campaign was a series of land and naval battles of the Pacific campaign of World War II between Allied forces and the Empire of Japan, named after the island of Bougainville. It was part of Operation Cartwheel, the Allied grand strategy in the South Pacific. The campaign took place in the Northern Solomons in two phases. The first phase, in which American troops landed and held the perimeter around the beachhead at Torokina, lasted from November 1943 through November 1944. The second phase, in which primarily Australian troops went on the offensive, mopping up pockets of starving, isolated but still-determined Japanese, lasted from November 1944 until August 1945, when the last Japanese soldiers on the island surrendered. Operations during the final phase of the campaign saw the Australian forces advance north towards the Bonis Peninsula and south towards the main Japanese stronghold around Buin, although the war ended before these two enclaves were comp ...
