Kawanishi H6K Mavis
Designed and built by Kawanishi Kokuki K. K. (Kawanishi Aircraft Company) at Naruo. In 1934, designed for an Imperial Japanese Navy (IJN) as a four-engine monoplane with twin tails, and a hull suspended beneath the parasol wing by a network of struts to meet a requirement for a long range flying boat as a followup to company's license-built H3K, an enlarged version of the Short Rangoon.
Delivered to the Imperial Japanese Navy (IJN) as Type 97 Large Flying Boat 九七式大型飛行艇 / Kawanishi H6K Mavis. At the start of the Pacific War, this flying boat was arguably the most advanced in the world with an incredible range and advanced features until replaced by the H8K2 Emily.
