Same with the Curtiss A-8, the A-10 and A-12 had different engines.Going back a way, the B-10, B-12 and B-14 were the same aircraft with different engines.
Like Brewster's SBA, which then became the SBN.One briefly alluded to was the Grumman F9F-9 which became the F11F. Also, the Naval Aircraft Factory built their production runs of other manufacturer's plans using N as the factory designator.
Me too and hello.Thanks for sharing all this interesting information about military aircraft designations. I'm always fascinated by the hidden meanings and secrets behind different designations.
The P-400 was not a US Military designation but applied to a version of the P-39 intended to be sold to other countries. A few of them were not delivered and saw duty as P-39s.
Grumman could not produce aircraft quickly enough for the Navy, so GM not only manufactured the TBF as the TBM, but the F4F as the FM and the F6F was planned as the F2M. FV-1 was the proposed designation for Hellcats to be built by Canadian Vickers.
The Chance Vought F4U Corsair was in great demand, so additional production contracts were given to Goodyear, whose Corsairs were designated FG, and Brewster, designated F3A.
However, the USAAC stuck with the same designation for B-29s, whether built by Boeing, Bell or Martin. Enola Gay is a Martin built B-29. Vega also built a lot of B-17s.
I have heard something very similar. I was an Estes model rocketeer.You've never heard of the flying door? Put enough power on it and you can fly a door!
Not an airplane, but it's planing! First saw this in a magazine advertisement for the brand (Mercury outboards).You've never heard of the flying door? Put enough power on it and you can fly a door!
