''I-364'' was an Imperial Japanese Navy Type D1 transport submarine. Completed and commissioned in July 1944, she served in World War II and was sunk during her first transport mission in September 1944. Construction and commissioning ''I-364'' was laid down on 26 July 1943 by Mitsubishi at Kobe, Japan, with the name ''Submarine No. 5464''. She was renamed ''I-364'' on 20 October 1943 and provisionally attached to the Yokosuka Naval District that day. She was launched on 15 February 1944 and was completed and commissioned on 14 June 1944. Service history Upon commissioning, ''I-364'' was attached formally to the Yokosuka Naval District and was assigned to Submarine Squadron 11 for workups.

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Mark 18 Torpedo
The Mark 18 torpedo was an electric torpedo used by the United States Navy during World War II. The Mark 18 was the first electric storage battery torpedo manufactured for the US Navy and it was designed primarily for use as a submarine-launched torpedo. Development The Mark 18 was built in competition with the Bureau of Ordnance electric torpedoes, which had been in development at the Naval Torpedo Station (NTS), Newport, Rhode Island, since the 1920s,, p. 280 in particular the Mark 20, originated in 1941 in collaboration with General Electric and Electric Storage Battery Company. In 1942, several German G7e electric torpedoes ran ashore, leading CNO, Admiral Ernest J. King, to urge BuOrd to build an electric torpedo for the U.S. Navy's own submarines. BuOrd told NTS to get the Mark 20 in shape, or drop it in favor of a copy, with the primary emphasis being speed of introduction. "Newport, typically, preferred its own finely machined project", but neither General E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zigzag
A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular. In geometry, this pattern is described as a skew apeirogon. From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection. Although the origin of the word is unclear, its first printed appearances were in French-language books and ephemera of the late 17th century. Examples of zigzags The trace of a triangle wave or a sawtooth wave is a zigzag. Pinking shears are designed to cut cloth or paper with a zigzag edge, to lessen fraying. In sewing, a ''zigzag stitch'' is a machine stitch in a zigzag pattern. The zigzag arch is an architectural embellishment used in Islamic, Byzantine, Norman and Romanesque architecture.

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rising Sun Flag
The is a Japanese flag that consists of a red disc and sixteen red rays emanating from the disc. Like the Japanese national flag, the Rising Sun Flag symbolizes the sun. The flag was originally used by feudal warlords in Japan during the Edo period (1603–1868 CE). On May 15, 1870, as a policy of the Meiji government, it was adopted as the war flag of the Imperial Japanese Army, and on October 7, 1889, it was adopted as the naval ensign of the Imperial Japanese Navy. At present, the flag is flown by the Japan Maritime Self-Defense Force, and an eight-ray version is flown by the Japan Self-Defense Forces and the Japan Ground Self-Defense Force. The rising sun design is also seen in numerous scenes in daily life in Japan, such as in fishermen's banners hoisted to signify large catches of fish, flags to celebrate childbirth, and in flags for seasonal festivities. The flag is controversial in Korea and China, where it is associated with Japanese militarism and imperialism. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commanding Officer
The commanding officer (CO) or sometimes, if the incumbent is a general officer, commanding general (CG), is the officer in command of a military unit. The commanding officer has ultimate authority over the unit, and is usually given wide latitude to run the unit as they see fit, within the bounds of military law. In this respect, commanding officers have significant responsibilities (for example, the use of force, finances, equipment, the Geneva Conventions), duties (to higher authority, mission effectiveness, duty of care to personnel), and powers (for example, discipline and punishment of personnel within certain limits of military law). In some countries, commanding officers may be of any commissioned rank. Usually, there are more officers than command positions available, and time spent in command is generally a key aspect of promotion, so the role of commanding officer is highly valued. The commanding officer is often assisted by an executive officer (XO) or second-in-com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...
