H8K2-L: Transport Version


Designed in response to a 1938 specification for a replacement for the Kawanishi H6K, the result was the H8K. Comprising the single greatest leap in flying boat technology, the H8K was the most advanced flying boat of WWII and for many years after the war.
In service 24-hour long patrols were typical. In fact, their first sortie was to have been a bombing raid on Oahu, Hawaii, with a stop for refueling by submarine. The mission was aborted due to weather over the target.


From other bits I have read about the H8K, it was a very good plane.
Not bad at all. I do not know how it would compare to the Cat and Sunderland though. My personal favourite fly boat has always been the Bv-238, Incidentally the largest plane to fly during the war.

Were there any Italian flying boats? I know of some of their seaplanes but I wasnt sure about flying boats. The Sm.55 was the closest I know of :lol:
