Aichi AB-12
The Aichi E10A was a Japanese night reconnaissance flying boat of the 1930s. A single-engined biplane, 15 were built for the Imperial Japanese Navy as the Type 96 Night Reconnaissance Seaplane, serving from 1936 but were retired in 1941 before the Attack on Pearl Harbor. Development and design In 1934, based on experience of testing the Experimental 6-Shi Night Reconnaissance Flying boat, the Imperial Japanese Navy drew up a specification for a new night reconnaissance aircraft, intended to shadow enemy fleets during the cover of darkness, with orders being placed with Aichi and with Kawanishi.Mikesh and Abe 1990, p. 76. Aichi's design, with the company designation AB-12, was a single-engined biplane flying boat of all-metal construction. Its two-bay wings folded rearwards to save space on board ship, while its crew of three were accommodated in an enclosed cabin. It was powered by a pusher water-cooled Aichi Type 91 engine, driving a four-blade wooden propeller.Mikesh and A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kawanishi E10K
The Kawanishi E10K, also known as Kawanishi Type T, Kawanishi Navy Type 94 Transport Seaplane and Kawanishi Navy Experimental 9-Shi Night Reconnaissance Seaplane, was a small Japanese flying boat of the 1930s. It was a single-engined biplane intended to meet a requirement for a night reconnaissance aircraft for the Imperial Japanese Navy but was not selected for production, the single prototype being converted to a transport and operated as the Navy Type 94 Transport. Design and development In 1934, the Imperial Japanese Navy issued a specification for a night reconnaissance aircraft, intended to shadow enemy ships at night, allowing submarines to be directed to their targets and, in a surface action, to spot for the guns of the fleet. This concept had been tested with the Aichi Experimental 6-Shi Night Reconnaissance Flying boat, which had proved unsuitable for service use. The aircraft was required to have good endurance and slow speed stability to help its crews in flying lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag (aerodynamics), drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. ...

Flying Boats
A flying boat is a type of seaplane with a hull (watercraft), hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy. Though a flying boat’s fuselage provides buoyancy, it may also utilize under-wing Float (nautical), floats or wing-like hull projections (called sponsons) for additional stability. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during the Second World War. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used as mar ...

1930s Japanese Military Reconnaissance Aircraft
Year 193 ( CXCIII) was a common year starting on Monday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Supermarine Walrus
The Supermarine Walrus is a British single-engine Amphibious aircraft, amphibious biplane designed by Supermarine's R. J. Mitchell. Primarily used as a maritime patrol aircraft, it was the first British Squadron (aviation), squadron-service aircraft to incorporate an Landing gear, undercarriage that was fully retractable, crew accommodation that was enclosed, and a fuselage completely made of metal. Supermarine originally named the type the Supermarine Seagull V, before changing it to the ''Walrus''. The type first flew in 1933, its design process had begun four years earlier as a private venture. It shared its general arrangement with that of the earlier Supermarine Seagull (1921), Supermarine Seagull. Having been designed to serve as a Surveillance aircraft, fleet spotter launched by aircraft catapult, catapult from cruisers or battleships, the aircraft was employed as a maritime patrol aircraft. Early aircraft had a metal hull for greater longevity in Tropics, tropical condi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aichi E11A
The Aichi E11A (九八夜偵, ''Kyū-hachi Yatei'') was an Imperial Japanese Navy flying boat used during the first year of World War II for maritime patrol duties. The Allied reporting name for this type was "Laura"; the Japanese Navy designation was "Type 98 Reconnaissance Seaplane". The Type 98 was quite similar to the earlier E10A Type 96, whose allied name was "Hank". "Lauras" were rare - only 17 were built. It was designed to be launched from cruisers or battleships in order to spot their shellfire at night. The Type 98s were soon diverted to communications and transport duties.

Code Name
A code name, codename, call sign, or cryptonym is a code word or name used, sometimes clandestinely, to refer to another name, word, project, or person. Code names are often used for military purposes, or in espionage. They may also be used in industrial counter-espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names. Origins Achaemenid Empire The Achaemenid Empire under Darius I employed a network of spies called the King’s Eye or the King’s Ear. These agents operated under anonymity, and “King’s Eye” was not a specific person but rather a code name for the intelligence network that reported directly to the king. Punic Wars The Carthaginian general Hannibal Barca reportedly used coded re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Military Aircraft Designation Systems
The Japanese military aircraft designation systems for the Imperial period (pre-1945) had multiple designation systems for each armed service. This led to the Allies' use of code names during World War II, and these code names are still better known in English-language texts than the real Japanese names for the aircraft. A number of different schemes were simultaneously in use. Imperial Japanese Navy Air Service The used several different aircraft designation systems simultaneously. Between 1931 and 1945, aircraft had ''Shi'' numbers designating the specification they were designed to. They also had a long form of Type and Model Number system used between 1920 and 1943, a short designation system akin to that of the United States Navy in use between the late 1920s and 1945, a system of popular names introduced to replace type numbers from 1943 through 1945. Specification ''Shi'' numbers Japanese Navy specifications from 1931 were given an experimental, or ''Shi'' (試) number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
