Aichi D1A "Susie"

The Aichi D1A ("Susie") was a carrier-based biplane dive bomber primarily used by the Imperial Japanese Navy during the Second Sino-Japanese War (1937–1940) for ground support, bombing Chinese vessels on the Yangtze River, and attacking ground targets. It was used extensively from aircraft carriers and land bases before being retired to second-line and training roles by 1941–1942. 
 
Key details regarding the usage of the Aichi D1A include:
Combat Service: It served as the primary dive bomber in the early stages of the Sino-Japanese War, where it gained fame for attacking the American gunboat USS Panay in 1937.
Operational Roles: It was operated by the Imperial Japanese Navy (IJN) on carriers and for coastal patrol. A limited number were used by the Manchukuo Imperial Navy.
Evolution: The D1A1 (Type 94) and D1A2 (Type 96) versions were developed, serving as the predecessor to the Aichi D3A ("Val").
Retirement: By the start of the Pacific War in December 1941, the D1A was largely removed from frontline combat, with many units used for training, although some 68 D1A2 models were used in second-line capacities until 1942.
Allied Reporting Name: The Allies assigned the D1A the reporting name "Susie".
