Bueschel Kawasaki Ki-61 Hein Richard M. Bueschel Mitsubishi Ki-67/Ki-109 Hiryu Richard M. Bueschel Notes: Note 1: The first batch of 24 model 32 production machines was made in 6/42. [Appendix F, Zero, Robert C. Mikesh (Forward by Saburo Sakai)] Note 2: The first batch of 76 A6M5 production machines was made in 8/43. Ibid. Note 3: The first batch of unknown size was made in 10/44. Op. cit. See also text discussion on p. 90, same source. Note 4: The first prototype completed in 4/45. The A6M5 went from prototype to production in 2 months. It is optimistic to assume operational status in 8/45. Included ONLY because this aircraft ALREADY part of CHS. Note 5: The first batch of unknown size was made in 7/43. Francillon. Note 6: This aircraft was prematurely sent to the Philippines for operations in 1/44, in spite of problems with engines and undercarriage that normally would not have permitted service acceptance. Actual IOC used. Francillon. Note 7: This aircraft was plagued by engine problems in spite of being sent to an operational unit to such an extent production was long restricted. Francillon. In spite of this, the actual IOC is used. Note 8: While the first flight did not occur until 8/45, the first prototype completed in 4/45 and under normal conditions could have occurred then. Using the logic of Note 4 above, we add 4 months to 4/45 to get 8/45. Francillon. Note 9: The first batch of unknown size was made in 8/43. Francillon. Note 10: The first batch of unknown size was made about 5/44. Francillon. Note 11: This transport is intermediate between a Ki-34 and a Ki-57 in performance. The Ki-56 is derived from the LO (Lockheed 14). If DNKKK (All Japan Air Lines) is it has about 32 machines (including 7 similar performing DC-2s). Francillon, Gunston and Weal. Note 12: Historical production delayed by an earthquake not imposed on players! This IOC date estimated on the same basis as Note 4 above. Note 13: Probably the worst bomber in the game, even worse than the Ki-36! This type added for use in ASW groups on Army carriers – in which role it might be useful. It COULD be added to certain JAAF HQ groups as well – for recon. Francillon. Note 14: Accepted for production in 3/43. Production probably began that month (as the failed D4Y1 was already in production). Francillon. Note 15: Added to permit creation of Army carrier air groups. This aircraft may also be used in regular fighter groups – but historically the Ki-84 was used instead. This aircraft was also intended for Army escort carriers. Sources differ about the production of this aircraft. IOC estimate based on 6/43 flight. Bueschel & Francillon. Note 16: Pre-production until 4/44. Production “began in the spring” interpreted as 5/44. Francillon. Note 17: The first batch of unknown size was made in 6/43. Francillon. Note 18: The first batch of unknown size was made in 5/44. Francillon. Note 19: The first batch of unknown size was made in 8/43. This aircraft was designed to function as a dive bomber. It was code named as a fighter by the Allies and was capable of marginal fighter operations. Francillon. Note 20: The first batch of unknown size was made in 7/43. Note 21: IOC based on first flight in 10/44 using the logic in Note 4. Note 22: IOC based on first flight in 8/43 using the logic in Note 4. Problems with the hydrolic system and engines prevented combat use until 1945, but this is ignored. Note 23: The first batch of unknown size was made in 6/44. Francillon.
