SS Kokai Maru (1939)
''Kokai Maru'' was a Japanese cargo steamship. She was built in Hokkaido in 1939, and sunk in the Pacific Ocean by United States Navy aircraft in 1944. Building The Hakodate Dock Company built ''Kokai Maru'', completing her in 1939. Her registered length was , her beam was and her depth was . Her tonnages were and . She had a single screw, driven by a three-cylinder triple expansion engine. Exhaust steam from her engine's low-pressure cylinder drove a compressor, which re-pressurised steam exhausted from the high-pressure cylinder before it entered the intermediate-pressure cylinder. Compressing the steam also increased its temperature, counter-acting steam's tendency to condense as it expands. ''Kokai Maru''s owner was Simatani Kisen Kabushiki Kaisha, who registered her at Kobe. Her wireless telegraph call sign was JOSJ. War service and loss In 1941 the Imperial Japanese Navy requisitioned ''Kokai Maru''. On 10 March 1942, during the Japanese invasion of Salamaua–Lae, U ...

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...

Ships Sunk By US Aircraft
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were c ...

North American B-25 Mitchell
The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber.

United States Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed among the Air Corps, General Headquarters Air Force, and the gro ...

Territory Of New Guinea
The Territory of New Guinea was an Australian-administered United Nations trust territory on the island of New Guinea from 1914 until 1975. In 1949, the Territory and the Territory of Papua were established in an administrative union by the name of the Territory of Papua and New Guinea. That administrative union was renamed as Papua New Guinea in 1971. Notwithstanding that it was part of an administrative union, the Territory of New Guinea at all times retained a distinct legal status and identity until the advent of the Independent State of Papua New Guinea. The initial Australian mandate, entitled the Mandate for the German Possessions in the Pacific Ocean situated South of the Equator other than German Samoa and Nauru, was based on the previous German New Guinea, which had been captured and occupied by Australian forces during World War I. Most of the Territory of New Guinea was occupied by Japan during World War II, between 1942 and 1945. During this time, Rabaul, on the ...

Invasion Of Salamaua–Lae
The invasion of Salamaua–Lae (8–13 March 1942), called ''Operation SR'' by the Japanese, was an operation by Imperial Japanese forces to occupy the Salamaua–Lae area in the Territory of New Guinea during the Pacific campaign of World War II. The Japanese invaded and occupied the location in order to construct an airfield and establish a base to cover and support the advance of Japanese forces into the eastern New Guinea and Coral Sea areas. The small Australian garrison in the area withdrew as the Japanese landed and did not contest the invasion. In response to the Japanese landings, a United States Navy aircraft carrier task force including the carriers and ''Lexington'' struck the invading Japanese naval forces with carrier aircraft on 10 March. Supporting the carrier aircraft were eight B-17 bombers of the 435th Bombardment Squadron of the 19th Bombardment Group from Garbutt Field, Townsville, Australia and eight Royal Australian Air Force Hudson bombers of No. 3 ...
