Yes!
That clears it up. The "F" was for Grumman. Not for: A, B. C......F. Those were the days when you could picture the a/c by its designation. If you read the "F" you could picture the big Grumman tail.

It was designated S2F because it was the second ASW aircraft built for the Navy by Grumman. With the Tri-Service designation system the S2F became the S-2. Why not S-1? Probably just to keep things as simple as possible. I think the AF was already out of service in the USN by the time the designation system was changed; that might explain the abscense of the "S-1". Thanks Steven. |

Yes but no S-1. AF -- S-2. Nope....AF -- S2F-(1-3) -- S-2(A-G) The location of the (-) makes a difference. Bob Moore S2F-1T NAS Kingsville 1959 |

Thanks Steven. The Grumman SF-1 was a version of the Grumman FF-1 fighter built in 1932-33. It had a 2 man cockpit that was reconfigured to make it a scout plane (SF), instead of a fighter (FF). After WW2, Grumman built the TB3F for ASW work. They worked in pairs AF-2W (hunter) and AF-2S (killer) because the equipment was too large and heavy for 1 aircraft. In 1953 they began replacing the AF with the S2F (because there had already been an SF). In 1962 when DOD started renumbering the aircraft to have a common number in all services, the Navy aircraft stayed with the number the aircraft already had (P2V-5 and P3V-1 became P-2E and P-3A). If two aircraft had the same number, one was changed (F3D and F3H became F-10 and F-3; F4D and F4H became F-6 and F-4). |

That sounds like a good reason not to redesignate an aircraft to me, but the DoD didn't agree. The Convair F2Y Sea Dart was redesignated F-7 under the Tri-Service designation system, five years after the program was canceled. |

AF was the largest single recip-engine a/c ever built.
They worked in pairs because they had different roles. The 'W' was the 'hunter'' Long range RADAR with large dish. The 'S' was the 'killer'. Localization equipment and weapons.

I believe there was already an F-2: The Beechcraft F-2 'Expeditor'.

The F2Y Sea Dart was included in the redesignation process, because a single YF2Y-1 had not yet been formally stricken from the Navy's inventory by June 1962 (when the process of selecting the new designations for all existing aircraft had already been completed)." ------ Robert Uncommon Aircraft: http://fire.prohosting.com/hud607/uncommon |
