No.101-class Landing Ship
The were a class of amphibious assault ships of the Imperial Japanese Navy (IJN) and Imperial Japanese Army (IJA), serving during and after World War II. The ''No.101'' class ships were powered by diesel engines, while the similar were powered by a steam turbine engine. The IJN called them . The ''No.103'' class included the IJA's variant. This article handles them collectively. Background *In June 1943, after its defeat in the Guadalcanal Campaign, the IJN realized it needed high-speed military transport vessels, and designed two classes of ship in response. One (the ) was to be the 1,500-ton mothership of the and Kō-hyōteki-class submarines, the other was to be a 900-ton amphibious assault ship, the No.101 class. *The IJA already had an amphibious assault ship, the . However, the SS craft were not suitable for mass-production, leading to IJA support for the new amphibious assault ships. *The IJN and IJA therefore cooperated on the production of the new amphibious assault ...

Sasebo Naval Arsenal
was one of four principal naval shipyards owned and operated by the Imperial Japanese Navy. History The Sasebo Naval District was established at Sasebo, Nagasaki in 1886, as the third of the naval districts responsible for the defense of the Japanese home islands. After the establishment of the navy base, a ship repair facility was established in 1889 with a dry dock. With the addition of equipment and facilities for ship production by 1897, the "Sasebo Shipyards" were officially established, and renamed the "Sasebo Naval Arsenal" in 1903. Construction of the arsenal was supervised by the French engineer Louis-Émile Bertin. In 1913, a 250-ton crane was installed, and the shipbuilding facilities expanded to permit the construction of large warships. With the mothballing of the Maizuru Naval Arsenal due to restrictions by the Washington Naval Treaty, much of the design and prototype work for new classes of destroyers and torpedo boats formerly done at Maizuru was shifted to ...

8 Cm/40 3rd Year Type Naval Gun
The Type 41 naval gun otherwise known as the 8 cm/40 3rd Year Type naval gun was a Japanese dual-purpose gun introduced before World War I. Although designated as , its shells were in diameter. Design The Japanese Type 41 naval gun otherwise known as the 8 cm/40 3rd Year Type naval gun was a direct copy of the English QF 12-pounder 12 cwt naval gun. The original 12-pounders were built-up guns with a single-motion interrupted screw breech that fired Fixed Quick Fire ammunition and had bottom mounted hydro-pneumatic recoil systems. Many were mounted on low-angle pedestal mounts in casemates as the standard anti-torpedo boat gun on Japanese warships built between 1890 and 1920. Later guns changed to an autofretted monoblock barrel, taller pedestal mount for increased angles of elevation -5° to +75°, top mounted recoil system, and 45° sliding block breech. The guns fired a high-explosive projectile. After 1915 the guns were mounted on high/low angle m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
