Only extant Emily of 167 built on display at JMSDF Kanoya. This H8K2 from 801 Ku wears the Takuma Ku 'T' code and Kikusui emblem. The definitive H8K2 Type 2 Model 12, of which 112 were built was powered by 1,850 hp MK4Q Kasei 22 engines. Prior to the Doolittle Raid, two H8K1s flew a 4,800-mile round trip from Marshall Is. with a refuelling stop by submarines at French Frigate Shoals to bomb Oahu unsuccessfully. IJN's largest LRMR aircraft equipped nine frontline units. USN post-war evaluation determined the fast and heavily armed H8K2 to be the most outstanding large flying boat of WW2.
