Although it is generally accepted that the XF-92 was the Model 7-002, I am faced with a couple of inconsistencies that some might be able to help me solve.
First of all, Convair used different numbering systems: The old Consolidated Model numbers ranged from 1 to 40; the unified Consolidated-Vultee Model numbers ranged from 100 to 118 and lasted only from 1945 to 1948 or about.
When Convair started their new model numbering system, only one of the previous list's models was redesignated: the Model 109 XB-46 became the Model 1. Also the Model 117 TRADEWIND (P5Y-1) was followed by the R3Y transport versions under the designation Model 3.
In 1946 Con.V.Air. submitted a radical supersonic day fighter interceptor proposal for Project MX-813 in the form of their Model 115 "DART", which the USAF ordered as the XP-92. This is where it gets complicated: according to some sources, the XP-92 (redesignated as XF-92 in 1948) became Model 6, while its delta demonstrator, the XF-92A, became the Model 7. Many sources, however, refer to both simply as being Model 7...
In both cases, we are faced with a MAJOR inconsistency: Model 6 was clearly a civilian double-deck transport project directly derived from the Consolidated Model 37 (XC-99), while Model 7 was allocated to the ATLAS-A and ATLAS-B missiles (X-11 and X-12)!
As if this wasn't bad enough, the chronology of Model number allocation would place the XF-92A right AFTER the 100-118 series and BEFORE the new series. The Models 5 (POGO), 6, 7, 8 (DELTA DAGGER) are all from 1953 or about, which is far too late for the XF-92A... Besides, the 1952 SEA DART (a naval development of the DART) is Model 2 !
For these reasons, I wonder if the "7-002" designation wasn't either a way to hide the secrecy of the program at some early , unless it had another meaning... Also, the Fairchild Archives mention the existence of a Convair Model 7-001 in their files, as if this whole thing wasn't bad enough!!!
Any help on this subject is of course most welcome...
