The patch consists of a white equilateral triangle, bordered in red, superimposed on a circular blue field. A red Arabic numeral "11" sits on silver prop and wings at the center.
The triangle superimposed upon the circle is borrowed from the 6th Bomb Wing, the original squadron sponsor. The triangle represents the Greek letter delta to remind all wearers that each new group of fourth classmen was assigned to Delta Squadron during basic cadet training. The three segments of the circle represent academics, athletics and military training. The silver prop and wings symbolize the cadet wing, while the large "11" identified the 11th Cadet Squadron. The emblem bears the squadron’s red and white colors; the gold, blue, silver and red class colors; and the cadet wing’s blue and silver colors.
This is the original squadron patch.
