Kawanishi E15K Shiun
The Kawanishi E15K Shiun (紫雲, Violet Cloud) was a single-engined, Japanese reconnaissance floatplane of World War II. The Allied reporting name for the type was "Norm" (after Squadron Leader Norman O. Clappison of the RAAF, member of the ATAIU). == Design and development == In 1939, the Imperial Japanese Navy instructed the Kawanishi Aircraft Company to develop a two-seat, high-speed reconnaissance floatplane, which was required to have sufficient performance to escape interception by land-based fighters as well as an 800-nautical mile range.
