I have attempted to structure the fuselage code letters used on USAAF WWII training aircraft into a meaningful
format. As of this writing I feel that the code data for Basic and Advanced flight training aircraft is fairly
complete. The data for fighter and multiengine bomber trainers is continuing to be collected. I welcome all information as
there are no doubt omissions and revisions to be made. Is this list correct, complete and without fault? Hardly,
it's a messy subject! Contact the webmaster with your input…Please!
Researching this information and organizing it into a meaningful format has been a most daunting
task. Actually, I have spent years collecting this information. I’ve obtained my information from books,
magazines, internet, libraries, photographs, e-mails and interviews with some very helpful people. This research project
was developed as no complete list of fuselage code letters for training aircraft has ever been documented. The only
formal USAAF documentation ever found on the subject was a letter written 20 May 1942 which identified the fuselage code
letters for 15 AAF's within the Southeast AAF Training Center centered at Hq. Maxwell Field, AL.. The Southeast AAF Training Center was later reorganized into the Eastern Flying Training Command (EFTC).
was that primary training aircraft would not display a fuselage letter code and carry only numerics
on the fuselage body. Typically, this numeric (1-999) was to be positioned on the fuselage aft of the rear pilot. The addition
or sole use of the aircraft serial number on the fuselage was not uncommon. Further, the US insignia was to be
displayed only on wing positions. To date I have documented two AAF's and one Primary School that did indeed display
a fuselage letter code on their aircraft as follows: Mather Field (CA) displayed the letter "I" on PT-22's
and Randolph Field PT-19's were marked with the letter "H". The Spartan Aircraft Co., Tulsa, OK ( a Primary
School) had at least one PT-19 with the fuselage letter code of "R".
Interestingly, the seven
British Flying Training Schools (BFTS) located in the U.S. did fly Primary aircraft with fuselage letter codes and
these are documented in the subsection of this document. Both PT-17 and PT-19 aircraft were utilized and supporting
photographs are included in that subsection.
It has been noted that in 1944-45 some Primary schools were utilizing Vultee Valiants for flight training.
These aircraft were no doubt excess to needs as AT-6's were replacing BT-13's for the Basic phase of flight training.
Basic and Advanced Training Aircraft
The US insignia was to be displayed on the wing with optional display on the fuselage. The fuselage
would carry either the s/n repeated on the fuselage and / or a sequential number assigned by the base (1-999) and in most
cases a large alpha character identifying the assigned base either singularly (e.g. 'P' for Pecos AAF, TX) or sometimes in
a dual manner (e.g. 'GE' for George Field, IL). This alpha character, roughly 30 inches in height, was typically
followed by a locally assigned three-character sequential number (e.g. GE 201, 202, ...). As there are always exceptions the author has identified aircraft with the letter code following the numeric,
some with four character numeric only and some with two and three alpha characters ( e.g.'CD' & 'KNF')
with no sequential numbers.
In 1944 the Vultee BT-13 began its phase-out as
a Basic Trainer and was slowly being replaced by the AT-6 for that phase of flight training. This decision was based on the
results of the British Flight Training School # 5 at Clewiston, FL who saw no purpose of the Vultee type in the training program.
The British felt that the aircraft was unchallenging because of the ease in which it could be flown. Much to the chagrin
the USAAF powers-that-be the RAF elected to phase their cadets directly from the PT-17 to the AT-6 and
was so successful that both the USAAF and the USN dropped the BT-13 Valiant from their flight training programs. Hence in
the Basic Training portion of the website it will be noted that the AT-6 is occasionally mentioned as a Basic trainer.
Interestingly, the alpha code(s) assigned was not a “tops-down” edict by USAAF Hq. but apparently done
on a local or possibly training command directive. There does seem to be a 'common thread' methodology for the EFTC and
the WFTC Commands as follows:
Eastern Flying Training Command (EFTC): There was a
strong tendency to choose a letter prefix that represents the first letter(s) of the AAF (e.g. "SP" for Spence
Field, "J" for Jackson AAF). The secondary scheme would be to use the first letter of the nearest city
(e.g "A" for, Augusta GA for Bush Field).
Western Flying Training Command (WFTC): There was a similar system
to above utilizing the AAF name...but not necesarily the first letter. For example Mather Field used the "T",
Stockton used the "K", Merced used the "E", Lemoore used the "R", Roswell used the "W".
The secondary method for the WFTC was to use a letter chosen from the name of a nearby city but then again not necessarily
the first letter. For example Kirtland Field used "Q" which was derived from the name of the community of
Albuquerque, Luke Field used "X" which was the last letter of Phoenix. Nearby
Williams Field used a "Y" which is the last letter in the name of the adjacent town of Higley. The use of "Z" for Las Vegas AAF remains a mystery.
Training Command (CFTC): Fuselage letter code usage was not that common within this command. Consequently,
in the tables that follow the expression of (NLA), meaning No Letter Assigned, is fairly common. In
the instances when a letter was used (as either a prefix or suffix) it appears that it was a locally chosen character
with no apparent meaning (e.g. 3A, 2H, etc.).
British Flying Training Schools (BFTS): A
wide variety of aircraft fuselage codes were used throughout the seven locations in the USA most of which do not make
sense. This mis-mash of letters is probably a result of excess aircraft passed on to them by the USAAF. However, there
is one common thread as such that did reveal itself in some schools, that is the letter "B" presumably for British. Lancaster
(CA) used letters "BL" for British Lancaster, Falcon Field (AZ) used "BP" for British
Phoenix, Ponca City (OK) used a "B" as did some aircraft at Miami, OK. The balance was an 'alphabet soup' of
letters ( i.e. H, W, S, V etc). Further there was a double letter system used without numerics (i.e. AA thru at least
AJ, CA thru C[x]) and finally a three letter system without numerics (HAB, KNF, KN[x], etc).
Transition Specialized Training
Transition Training was the last
phase following Advanced where pilots were introduced to higher performance fighters or multi-engine bombers and transports
for the first time. The fighter aircraft utilized were P-39, P-40, P-47, et.al. and the fuselage codes assigned
were single letters such as A, B, C, D, V, etc. with a lot of redundancy among the bases. How these code letters
were chosen and allocated is unknown but I have documented what I have found for historical purposes.
engine bomber trainers typically were B-25, B-26 or A-20 aircraft all displaying quite a variety of letter and number code
formats. Generally speaking the majority of these aircraft carried the letter code on the nose and sometimes repeated on the
tail. Again a variety of other nose codes have been noted. (e.g. a
four digit numeric only, a single letter followed by one or more numerics,etc.).
Four engine bomber trainers
also displayed a variety of letter code formats sometimes making logical sense (e.g. 'A' for Avon Park, 'D' for Drew Field).
Other times there was no logical geographical association (e.g. 'BM' for Moses Lake). Sometimes the code letter was carried
on the fuselage other times on the vertical tail only and sometimes in both positions.
All constructive input is more than welcomed.
