World War II Bombardment Group aircraft of the Mighty Eighth Army Air Forces were distinguished by multiple markings on the aircraft. For example, tail markings included Group codes made up of symbols and letters designating the Bomb Division and Bomb Group, and aircraft serial number. The fuselage markings designated squadron codes and identification letters and included changing national insignias over time.
This article will take a look at tail markings, specifically the Bombardment Group Codes. Other aircraft markings will be covered in subsequent articles.
Three Bombardment Divisions, the 1st, 2nd, and 3rd, made up the Mighty Eighth Air Force based in England. Each Bombardment Division used a different symbol, a triangle for the 1st, a circle for the 2nd, and a square for the 3rd. Each Bombardment Group of each division used a letter placed within the division’s symbol to signify their Group.
The Bomb Group “Codes,” the combinations of symbols and letters are outlined below in the following chart and lists.

384th Bomb Group Symbol
As the 384th Bombardment Group, of which my father was a waist gunner in WWII, was part of the 1st Bomb Division and was assigned the letter “P,” their symbol was the Triangle P.
The Triangle P appeared on the tail of all 384th Bomb Group B-17’s, like 42-107121 KENTUCKY COLONEL (aka HELENA II) and 43-38062 PLEASURE BENT here,
Future articles will explain additional aircraft markings of the Eighth Air Force’s bombers of WWII…

As always, very informative. I did not know that the triangle-P indicated Grafton-Underwood, where my father was based.

I’m trying to get a better handle on these AC markings myself, so thought I might as well share what I’m learning.

They can be quite tricky. This actually clarifies them a lot.
