However the size of the Allied air forces began to exhaust possible two-letter combinations, and made difficult the timely assembly of heavy bomber tactical formations. However sixteen squadrons of B-17s of the new VIII Bomber Command, beginning in December 1942, also received this identification system, which continued in the spring and summer of 1943 when VIII Bomber Command quadrupled in size.

The markings were two-letter fuselage squadron codes located on one side of the national insignia and a single letter aircraft code on the other side. The first Eighth Air Force aircraft to receive unit markings were the Spitfires of the 4th and 31st Fighter Groups training with RAF Fighter Command in September 1942. Some pre-war bands and stripes were reinstated.

As in Europe, geometric shapes and colors were used as were letters, numbers and variations based on the RCN or serial number last three or four digits. The patterns or themes varied some were designated at the Air Force level, some at the Command level and others down at Group or squadron level. The other six numbered air forces fighting in the Pacific War also used tail markings within the various air forces both as group and squadron identifiers. The Twentieth Air Force, eventually operating 20 groups and 1,000 bombers, also adopted a tail identification system overseas. However, as unpainted ("natural metal finish") aircraft became policy at the start of 1944, the system evolved gradually to one using large areas of color in conjunction with symbols or patterns of color identifying the wing and often different colors for the group. Both the Eighth and Fifteenth Air Forces used a system of large, readily-identifiable geometric symbols combined with alphanumerics to designate groups when all USAAF bombers were painted olive drab in color. To facilitate control among thousands of bombers, the USAAF devised a system of aircraft tail markings in 1943 to identify groups and wings. Other areas continued to use only the RCN or simple numbering and lettering.Īs the buildup of troops continued in the Europe, Africa, Middle East Campaign (EAME), the United States Strategic Air Forces in Europe (USSTAF) bomber formations grew and assembly necessitated better visual unit identification at greater distance. A additional single letter, known as the Radio Call Letter (RCL), was to identify the aircraft within the squadron, used phonetically in radio calls. Two-letter squadron codes were used to denote a squadron some squadron codes later consisted of a letter and a numeral. The purpose of these markings was to serve as call signs in the Royal Air Force (RAF) radio procedures used in the UK and to provide a visual means of identification in conjunction with the call procedures, and later assembly and combat visual identification of units and aircraft.
USAAF unit identification aircraft markings, commonly called "tail markings" after their most frequent location, were numbers, letters, geometric symbols, and colors painted onto the tails (vertical stabilizer fins, rudders and horizontal surfaces), wings, or fuselages of the aircraft of the United States Army Air Forces (USAAF) during the Second World War.
