Have you ever seen anything so frustrating, complicated and seemingly illogical as Waco aircraft designations? I haven't often, personally.

And yet, there WAS a logic to those obscure all-letter codes... I have attempted to reconstruct a list as best as I could, and although there is bound to be a few omissions and possibly a mistake here and there, I believe this is a good step forward to help understand that Waco mess... Feel free to correct and update if you can!

Letter designations

This system consists of three letters and sometimes a hyphenated numeral at the end.

  • Prefix = NUMBER OF ENGINES (no prefix for most types, the prefix "2-" used on the powered gliders and C-62 transport)
  • First letter = POWERPLANT (motor codes - with "N" used for gliders, presumably for "NO engine")
  • Second letter = AIRFRAME DESIGN (indicated specific drawings or design changes, varying considerably within individual models)
  • Third letter = SERIES (Waco type)
  • Suffix = REMARKS (dash number generally indicated first year of production)
A detailed explanation of how the system worked can be found here (thanks, Jos!):

Aerofiles, at http://www.aerofiles.com/wacodata.html, provides a good explanation of what all those Waco codes mean.

As far as the USAAF designations are concerned:
1. C-62 was never built so may not have reveived a Waco designation;
2. CG-13 was Waco NLB
3. PG-3 was Waco YEU
4. TG-8 was a Piper, not Waco

Awesome! Thanks Jos for reminding me of the Aerofiles site.

I'm impressed that you got the designations for CG-13 and PG-3. I looked for these for ages!
As for the TG-8, of course it was a mistake on my part, sorry about that.

Some very interesting insight on the very early Wacos, taken from Air-Britain Digest, Summer 1996:

The Waco CG-15 was the NEU (the other Model U being the powered variant of the CG-13, the YEU).

The YC-62 transport was the Model 2-FBH, and another source gives the XPG-3 as the Model 2-YEU.

Quite obviously, the "2-" prefix was added when the type was a twin-engined aircraft.

My pleasure! Here are the postwar types I'm aware of:

  • S-220 Sirius > S-220-4 Sirius > Vela I (version of SIAI-Marchetti S.205/22R)
  • S-220-5 Vela (five-seat version of the S.205/22R)
  • SF-260-3 Meteor I > TS-250-3 Meteor (version of SIAI-Marchetti/Frati SF.260)
  • TS-250-6 Nova (project to assemble and sell the twin-engine SIAI-Marchetti S.210 in America)
  • Minerva (version of Morane-Saulnier MS.894 Rallye Minerva, later SOCATA Rallye 220)
  • Vega (existed?)

I haven't got your Meteor 2 or your Model "FT" in my list.
