The Kyushu Q1W Tokai (東海, "Eastern Sea"), was a land-based anti-submarine patrol bomber aircraft developed for the Imperial Japanese Navy in World War II. The Allied code name was Lorna.
The Navy ordered development as the 17-shi in September 1942, and the first test flight took place in September 1943. It entered service in January 1945. The Q1W carried two low-power engines, allowing for long periods of low-speed flight, and was the first purpose-designed anti-submarine warfare aircraft in the world. A total of 143 examples were produced.
