Operation Road's End
The Imperial Japanese Navy (IJN) submarines were the largest submarines of World War II, with the final completed submarine being finished roughly a month before the end of the war. The ''I-400s'' remained the largest submarines ever built until the construction of nuclear ballistic missile submarines in the 1960s. The IJN called this type of submarine , shortened from . They were submarine aircraft carriers able to carry three Aichi M6A ''Seiran'' aircraft underwater to their destinations. They were designed to surface, launch their planes, then quickly dive again before they were discovered. They also carried torpedoes for close-range combat. The ''I-400'' class was designed with the range to travel anywhere in the world and return. A fleet of 18 boats was planned in 1942, and work started on the first in January 1943 at the Kure, Hiroshima arsenal. Within a year the plan was scaled back to five, of which only three ( ''I-400'' at Kure, and and ''I-402'' at Sasebo) were compl ...

Magnetic Field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, electric currents, and electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function (mathematics), function assigning a Euclidean vector, vector to each point of space, ...

Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diving Plane
Diving planes, also known as hydroplanes, are control surfaces found on a submarine which allow the vessel to Pitch (flight), pitch its bow and stern up or down to assist in the process of submerging or surfacing the boat, as well as controlling depth when submerged. Bow and stern planes Diving planes are usually fitted in two pairs, the ''bow (ship), bow planes'' at the front of the submarine and the ''stern planes'' at the rear. The stern planes function in much the same way as an aircraft's elevator (aircraft), elevator. As the planes are a long distance fore-and-aft from the hull's centre of buoyancy, they introduce a pitching moment. Ballast tanks within the submarine adjust buoyancy to be neutral, making the boat controllable. The position of the planes controls the pitch (aviation), pitch of the boat and, with the forward motion of the boat, this controls depth. If not carefully controlled, this could lead to a Phugoid, 'porpoising' motion whereby the planesman continua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetization
In classical electromagnetism, magnetization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. Accordingly, physicists and engineers usually define magnetization as the quantity of magnetic moment per unit volume. It is represented by a pseudovector M. Magnetization can be compared to Polarization density, electric polarization, which is the measure of the corresponding response of a material to an electric field in electrostatics. Magnetization also describes how a material responds to an applied magnetic field as well as the way the material changes the magnetic field, and can be used to calculate the forces that result from those interactions. The origin of the magnetic moments responsible for magnetization can be either microscopic electric currents resulting from the motion of electrons in atoms, or the Spin (physics), spin of the electrons or the nuclei. Net magnetization results from the response of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunwale
The gunwale () is the top edge of the hull of a ship or boat. Originally the structure was the "gun wale" on a sailing warship, a horizontal reinforcing band added at and above the level of a gun deck to offset the stresses created by firing artillery. Over time it remained as a valuable stiffener mounted inboard of the sheer strake on commercial and recreational craft. In modern boats, it is the top edge of the hull where there is usually some form of stiffening, often in the form of traditional wooden boat construction members called the "inwale" and "outwale". On a canoe, the gunwale is typically the widened edge at the top of its hull, reinforced with wood, plastic or aluminum, to carry the thwarts. On a narrowboat A narrowboat is a particular type of Barge, canal boat, built to fit the narrow History of the British canal system, locks of the United Kingdom.

25mm Gun
25 mm caliber is a range of autocannon ammunition. It includes the NATO NATO cartridge, standardized Swiss 25×137mm, the Swiss 25×184mm, the Soviet 25x218mmSR, and the Chinese 25×183mmB. Usage The 25 mm round can be used for anti-materiel or Anti-personnel weapon, anti-personnel purposes. In the anti-personnel role, a 25 mm High explosive, HE rounds can kill large numbers of opposing troops either in the open or in light fortifications. In the anti-materiel role, a 25 mm weapon armed with Armor-piercing shot and shell, armor-piercing rounds can disable many types of aircraft and ground vehicles, including some main battle tanks. The United States armed forces, US military uses 25 mm weapons in their AV-8B Harrier, AC-130 gunship, M2 Bradley, LAV-25, F-35 Lightning II and as a standard ship-based munition in the Mk 38 autocannon.

Operation Vengeance
Operation Vengeance was the American military operation to kill Admiral Isoroku Yamamoto of the Imperial Japanese Navy on 18 April 1943 during the Solomon Islands campaign in the Pacific Theater of World War II. Yamamoto, commander of the Combined Fleet of the Imperial Japanese Navy, was killed near Bougainville Island when his G4M1 transport aircraft was shot down by United States Army Air Forces fighter aircraft operating from Kukum Field on Guadalcanal. The mission of the U.S. aircraft was specifically to kill Yamamoto, made possible because of United States Navy intelligence decoding transmissions about Yamamoto's travel itinerary through the Solomon Islands area. The death of Yamamoto reportedly damaged the morale of Japanese naval personnel, raised the morale of the Allied forces, and was intended as revenge by U.S. leaders, who blamed Yamamoto for the attack on Pearl Harbor that initiated the war between Imperial Japan and the United States. The U.S. pilots claimed to ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Empire of Japan on the United States Pacific Fleet at Naval Station Pearl Harbor, its naval base at Pearl Harbor on Oahu, Territory of Hawaii, Hawaii, on December 7, 1941. At the time, the U.S. was a Neutral powers during World War II, neutral country in World War II. The air raid on Pearl Harbor, which was launched from Aircraft carrier, aircraft carriers, resulted in the U.S. entering the war on the side of the Allies of World War II, Allies on the day following the attack. The Imperial General Headquarters, Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. The attack on Pearl Harbor was preceded by months of negotiations between the U.S. and Japan over the future of the Pacific Ocean, Pacific. Japanese demands included that the U.S. ABCD line, end its sanctions against Japan, cease aidi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
