William R Leon, e-mail, 04.12.2025 11:29 I found some of the data on the D1A1. It had a top speed of about 174 mph and had a service ceiling of about 7,000 meters. It had an effective range of about 685 miles. Armament and bombload remained the same. Production was limited to 162 machines.

William R. Leon, e-mail, 04.12.2025 10:19 Do we have access to any of the specifications to the D1A1? I have a few. Namely it had a different engine. For most examples it was powered by a Nakajima "Kotobuki 3" 9-cylinder air-cooled radial engine. This powerplant produced approximately 580hp, so it was somewhat slower than the D1A2. What I am looking for are the specifications of the D1A1.
