Yokosuka Naval Air Technical Arsenal
had many names, each depending on the period of its existence, and the circumstances at that time. Many of the names were acronyms that were derived from its military name or designation, which changed from time to time. The arsenal was sometimes known as "Kūgi-shō" (空技廠, a contraction of "Kōkū Gijutsu-shō" 航空技術廠).Francillon, p 446 The name Yokosuka prevailed however, even though it referred to the Arsenal's location at Yokosuka, Japan.Mikesh, Robert and Shorzoe Abe. ''Japanese Aircraft 1910–1941''. London: Putnam, 1990. History The air arsenal's roots go back to 1869 when the Imperial Japanese Navy (IJN) established a naval arsenal at Yokosuka, about 13 miles south of Yokohama on Tokyo Bay. The arsenal provided ship building, repair and replenishment to the Japanese Navy. It was also a storage depot where munitions and other assorted supplies were brought as they were purchased. When a number of foreign aircraft were purchased for evaluation, the Navy b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

Kugisho B3Y
The Kugisho B3Y, or Navy Type 92 Carrier Attack Bomber, also popularly titled Yokosuka B3Y, was a Japanese carrier-based torpedo bomber of the 1930s. It was designed by the Naval Air Technical Arsenal at Yokosuka, and while unimpressive during testing, it was ordered into service by the Imperial Japanese Navy and used until replaced by more capable aircraft. Development and design In 1932, the Imperial Japanese Navy had a requirement, 7-''Shi'', for a new torpedo bomber to replace the Mitsubishi B2M. The air arsenal at Yokosuka prepared its own design to meet this requirement, competing against designs by Mitsubishi and Nakajima. The resulting aircraft was a three-seat single-engine biplane, with a fuselage of steel tube construction and two-bay wooden wings that could fold rearwards for storage aboard aircraft carriers. It was powered by a single Hiro Type 91 W engine rated at 450 kW (600 hp). Testing proved that the aircraft had poor stability and control, and tha ...

Yokosuka E1Y
The Yokosuka E1Y was a Japanese floatplane of the 1920s. A single-engined biplane that was designed and developed by the Yokosuka Naval Air Technical Arsenal as a reconnaissance aircraft for the Imperial Japanese Navy, 320 were built as the Type 14 Reconnaissance Seaplane, entering service in 1925 and remained in operational service until 1932. Development and design In 1921, the Japanese Naval Arsenal at Yokosuka started design of a single-engined reconnaissance floatplane to replace the Navy's Yokosuka Ro-go Ko-gata floatplanes. The resulting aircraft, the Type 10 Reconnaissance Seaplane was designed by a team led by a member of a visiting delegation from Short Brothers of the United Kingdom. It was a single-engined two-bay, two-seat biplane powered by a 400 hp (298 kW) Lorraine-Dietrich engine. Two were completed in 1923, but showed poor performance due to being overweight. A modified aircraft, the Type 10 Model A flew in 1924, showing only slight improvement, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yokosuka Ro-go Ko-gata
The Yokosuka Ro-go Ko-gata (YokoSho-shiki Ro-go Ko-gata) was a Japanese reconnaissance floatplane developed during the First World War by the Japanese Navy Arsenal at Yokosuka, and one of the first indigenous Japanese aircraft to enter production. There were 218 of these aircraft built for the Imperial Japanese Navy, which remained in use until 1928. Development and design The Japanese Navy Arsenal at Yokosuka became involved in aircraft production in 1913, when an aeroplane factory was set up, with its first work being to build several Maurice Farman and Curtiss Seaplanes.Mikesh and Abe 1990, pp. 262–263. It continued to build aircraft under license, including more Farman aircraft and several Short 184 seaplanes, as well as prototypes of several of its own designs.Mikesh and Abe 1990, pp. 264–268. In 1917, Chikuhei Nakajima, chief designer of the Yokosuka Arsenal aircraft factory designed a new reconnaissance floatplane. A prototype of this new design, powered by a 140 ...

Aichi D3A
The Aichi D3A Type 99 Carrier Bomber ( Allied reporting name "Val") is a World War II carrier-borne dive bomber. It was the primary dive bomber of the Imperial Japanese Navy (IJN) and was involved in almost all IJN actions, including the attack on Pearl Harbor. The Aichi D3A was the first Japanese aircraft to bomb American targets in the war, commencing with Pearl Harbor and U.S. bases in the Philippines, such as Clark Air Force Base. They sank more Allied warships than any other Axis aircraft. Design and development In mid-1936, the Japanese Navy issued the 11-Shi specification for a monoplane carrier-based dive bomber to replace the existing D1A biplane then in service. Aichi, Nakajima, and Mitsubishi all submitted designs, with the former two subsequently being asked for two prototypes each. The Aichi design started with low-mounted elliptical wings inspired by the Heinkel He 70 ''Blitz''. It flew slowly enough that the drag from the landing gear was not a serious iss ...

Yokosuka D3Y
The was a Japanese two-seat dive bomber/trainer designed and built by the Yokosuka Naval Air Technical Arsenal. Derived from the Aichi D3A, it was made nearly entirely of wood in an attempt to conserve valuable resources. Upon Japan's surrender, the project came to a halt with only a few aircraft delivered as the Navy Type 99 Bomber Trainer Myojo Model 22. Design and development The D3Y was a two-seat bomber trainer constructed of wood, so as not to use more valuable materials. It was based on the successful Aichi D3A with design starting in late 1942. Like the D3A, it was a two-seat low-winged monoplane with a fixed tailwheel undercarriage. To allow construction by unskilled workers, the elliptical wing and rounded tail of the D3A were replaced by straight tapered alternatives, while the fuselage was lengthened to improve stability. Two prototypes were built during 1944, but these proved heavier than expected. Three production aircraft, which were redesigned to save weight, wer ...
