Aircraft, Flying Boat, Kawanishi H6K

History: The Kawanishi H6K was an Imperial Japanese Navy flying boat produced by the Kawanishi Aircraft Company and used during World War II for maritime patrol duties. The Allied reporting name for the type was Mavis; the Navy designation was "Type 97 Large Flying Boat" (九七式大型飛行艇).

H6Ks were deployed from 1938 onwards, first seeing service in the Sino-Japanese War and were in widespread use by the time the full-scale Pacific War erupted, in December 1941. At that time of the war, four Kōkūtai (air groups) operated a total of 66 H6K4s.

The type had some success over South East Asia and the South West Pacific. H6Ks had excellent endurance, being able to undertake 24-hour patrols, and were often used for long-range reconnaissance and bombing missions. From bases in the Dutch East Indies, they were able to undertake missions over a large portion of Australia.

However, the H6K became vulnerable to a newer generation of heavier armed and faster fighters. It continued in service throughout the war, in areas where the risk of interception was low. In front-line service, it was replaced by the Kawanishi H8K.

Railroad/Company: The Kawanishi Aircraft Company (川西航空機) was a Japanese aircraft manufacturer during World War II. It was founded as Kawanishi Engineering Works in 1920 in Hyōgo Prefecture as an outgrowth of the Kawanishi conglomerate, which had been funding the Nakajima Aircraft Company. Kawanishi built its first aircraft, the Kawanishi K-1 Mail-carrying Aircraft in 1921, and set up an airline, Nippon Koku K.K. (Japan Aviation Co. Ltd) in 1923, designing and building several aircraft for the airline's use. It was forced by the Japanese government to shut down Nippon Koku in 1929, however, with its routes being transferred to the government-owned Nippon Koku Yuso K.K. (Japan Air Transport Co. Ltd.) Kawanishi then split off the former Kawanishi Engineering Works, forming Kawanishi Kokuki KK in 1928, taking all of the Kawanishi Engineering Works' assets. While Kawanishi was best known for its seaplanes, such as the Kawanishi H6K and H8K flying boats, its N1K-J land-based fighter -derived from their Kawanishi N1K1 floatplane fighter- was considered one of the best in the war. After Japan's defeat, the company was reborn as Shin Meiwa Industries (later ShinMaywa), and continued to create flying boats such as the PS-1 and US-2.
