The Kawanishi H8K (Allied code name Emily) was a large, four-engine Japanese flying boat used in the Pacific as a reconnaisance aircraft, bomber, and transport. Its perfomance during the war was considered exceptional combining fast flying capabilities and superior hydrodynamic qualities. The H8K was first used in combat in 1942 and earned a reputation among Allied forces as one of the hardest Japanese aircraft to shoot down. It was considered the backbone of the Imperial Japanese Navy’s maritime reconnaissance element. The H8K carried a crew of ten and was armed with nose, dorsal and tail machine gun turrets.
