Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Japanese Destroyer Oboro (1930)
was the seventeenth of twenty-four s, built for the Imperial Japanese Navy following World War I. When introduced into service, these ships were the most powerful destroyers in the world. They served as first-line destroyers through the 1930s, and remained formidable weapons systems well into the Pacific War. History Construction of the advanced ''Fubuki''-class destroyers was authorized as part of the Imperial Japanese Navy's expansion program from fiscal 1923, intended to give Japan a qualitative edge with the world's most modern ships. The ''Fubuki'' class had performance that was a quantum leap over previous destroyer designs, so much so that they were designated . The large size, powerful engines, high speed, large radius of action and unprecedented armament gave these destroyers the firepower similar to many light cruisers in other navies. ''Oboro'', built at the Sasebo Naval Arsenal, was the seventh in an improved series, which incorporated a modified gun turret that co ...

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 con ...

Mark 13 Torpedo
The Mark 13 torpedo was the U.S. Navy's most common aerial torpedo of World War II. It was the first American torpedo to be originally designed for launching from aircraft only. They were also used on PT boats. Design Originating in a 1925 design study, the Mark 13 was subject to changing USN requirements through its early years with resulting on-and-off development. Early models—even when dropped low to the water at slow speeds—were prone to running on the surface, or not running at all. By late 1944, the design had been modified to allow reliable drops from as high as , at speeds up to . The final Mark 13 weighed ; of this was the high explosive Torpex.NavWeaps (18 February 2005).USA Torpedoes of WWII. Retrieved 2 August 2005.

Invasion Of Lae-Salamaua
An invasion is a military offensive in which large numbers of combatants of one geopolitical entity aggressively enter territory owned by another such entity, generally with the objective of either: conquering; liberating or re-establishing control or authority over a territory; forcing the partition of a country; altering the established government or gaining concessions from said government; or a combination thereof. An invasion can be the cause of a war, be a part of a larger strategy to end a war, or it can constitute an entire war in itself. Due to the large scale of the operations associated with invasions, they are usually strategic in planning and execution. History Archaeological evidence indicates that invasions have been frequent occurrences since prehistory. In antiquity, before radio communications and fast transportation, the only way for a military to ensure adequate reinforcements was to move armies as one massive force. This, by its very nature, led to the s ...

1st Air Fleet Of The Imperial Japanese Navy
The , also known as the ''Kidō Butai'' ("Mobile Force"), was a name used for a combined carrier battle group comprising most of the aircraft carriers and carrier air groups of the Imperial Japanese Navy (IJN) during the first eight months of the Pacific War. At the time of its best-known operation, the attack on Pearl Harbor, in December 1941, the 1st Air Fleet was the world's largest fleet of aircraft carriers. In its second generation, 1st Air Fleet was a land-based fleet of "kichi kōkūtai" (base air unit(s)). Origins In 1912, the British Royal Navy had established its own flying branch, the Royal Naval Air Service (RNAS). The IJN was modeled on the Royal Navy and the IJN Admiralty sought establishment of their own Naval Air Service. The IJN had also observed technical developments in other countries and saw military potential of the airplane. In 1913, the IJN seaplane carrier ''Wakamiya'' was converted into a seaplane tender and aircraft were purchased. The 1st and 2nd Air ...

1st Fleet (Imperial Japanese Navy)
The was the main battleship fleet of the Imperial Japanese Navy. History First established on 28 December 1903, the IJN 1st Fleet was created during the Russo-Japanese War when the Imperial General Headquarters divided the Readiness Fleet into a mobile strike force of cruisers and destroyers to pursue the Imperial Russian Navy's Vladivostok-based cruiser squadron (the Imperial Japanese Navys 2nd Fleet), while the remaining bulk of the Japanese fleet (the IJN 1st Fleet) continued to blockade Port Arthur in hopes of luring the battleships of the Russian Pacific Fleet out into a classic line-of-battle confrontation. The two fleets were combined into the Combined Fleet for the final Battle of Tsushima. The decisive victory of the Japanese fleet over the Imperial Russian Navy at the Battle of Tsushima validated the doctrine of the "decisive victory", or '' kantai kessen'' as stipulated by naval theorists such as Alfred Thayer Mahan and Satō Tetsutarō in the eyes of the Imperia ...
