This may be a bit OCD as a topic, but I do think it's a worthy debate. Too much in history is being rewritten by those who don't understand the subtlety of such things. One thing has often made me wonder however - the subject of US Naval type designations, especially with reference to manufacturer code letters.
Most (for instance), do it in the the 'mission letter - type number - manufacturer code letter' order, so that we have, for instance F4F, F5F, F6F, F7F, F8F etc for the various Grumman Cats.
However, how did Ryan manage to follow suit with the XF2R(-1) but not the preceding FR-1 Fireball or the later XFR-4?
North American seems to have adopted a similar route with is Fury series (FJ-1, FJ-2, FJ-3 and FJ-4 (and FJ-5)), which I assume should have really been, 'F1J, F2J, F3J and F4J'. Ditto the AJ Savage. But why the apparent variety in the way these types were described?
It's worth noting that NAVAER 00-25Q-13 (Model Designation of Naval Aircraft) of October 1947 lists the manufacturer code letters, but makes no attempt to standardise the way they were applied. For info, the following were listed as manufacturers at that time:
B - Boeing Aircraft Company, Seattle
C - Curtiss Wright Corporation, Columbus
D - Douglas Aircraft Co., Inc., Santa Monica Plant/Douglas Aircraft Co., Inc., EI Segundo Plant
E - Edo Aircraft Corporation, College Point
F - Grumman Aircraft Engineering Corp., Bethpage
H - McDonnell Aircraft Corporation, St. Louis (formerly 'D')
J - North American Aviation Inc., Los Angeles
M - Glenn L. Martin Company, Baltimore
N - Naval Aircraft Factory, NAMC Philadelphia
O - Lockheed Aircraft Corp., (Factory "B") Burbank
Q - Fairchild Engine & Airplane Corp., (Fairchild Aircraft Div.) Hagerstown
R - Ryan Aeronautical Company. San Diego
U - Chance Vought Aircraft Div. of United Aircraft Corp., Stratford
V - Lockheed Aircraft Corp., (Factory "A") (formerly Vega), Burbank
Y - Consolidated Vultee Aircraft Corp., (San Diego Div.) San Diego
The Grumman series should be FF F2F F3F F4F etc. F for fighter, F for Grumman with the '1' assumed, and the '2' etc only coming in when the same manufacture makes a subsequent type. The AJ is NAA's first attack design accepted. the next one would be A2J, then A3J etc
The FJ Furies are considered all to the same Type, with the -1,-2 being variations only
The Ryan starts with FR. the '-1' is a variation on the FR, not a new designation. Next Ryan, as you say, is XF2R. the dash after the R indicates a variation on the the basic airframe, not a new type, so XFR-4 is a variation on FR, otherwise it would be F4R and make you wonder what happened to the F3R.
There are bound to be screw ups and politics. The current F-35 is a prime example. It was a follow up to the X-35 demonstrator, but was popularly termed F-35 instead of (I think) F-24 which is where it SHOULD fall. The B-50 should have been the B-29E or F, but there would have been no funding for more "old" B-29's bombers, but yes for the "new" B-50
