Here is some info I found on the Navy Historical Center's website concerning the WWII regulations for the Combat Aircrew Wing.
The initial requirements for insignia were:
a. Having served, subsequent to 7 December 1941, for a total of three months as a regularly assigned
member of the Air Crew of a combatant craft.
(1) “Combat aircraft” shall be considered as all operating aircraft of the Fleet or Frontier
Forces, and excepts utility aircraft which are neither designed nor fitted out for offensive
(or defensive) operations. (2) The term “regularly assigned member of the
Air Crew” shall be interpreted literally, and shall be substantiated by the battle station bill
of the unit, under such instructions that may be approved and promulgated by the Bureau
of Naval Personnel.
b. Having suffered injuries or other physical impairment, while engaged in combatant operations since 7
December 1941, as a regularly assigned member of a combatant aircraft, which precludes the possibility of
fulfillment of the time requirements, stated in subparagraph (a) above, and is recommended by the
Commanding Officer of the Unit in which injury or physical impairment was received.
c. Individual combat stars will be authorized by Unit Commanders, in conformance with instructions issued
by Commander-in-Chief, United States Fleet, to those members of Air Crews who:
(1) Engage enemy aircraft, singly or in formation.
(2) Engage armed enemy combatant vessels with bombs, torpedoes, or machine guns.
(3) Engage in bombing offensive operations against enemy fortified positions.
(4) A maximum of three combat stars shall be awarded for display on the Air Crew Insignia;
combat actions reports in excess of three will be credited only in the record of the individual concerned.
d. Personnel qualified by provisions of subparagraphs A and B above may wear the Air Crew Insignia permanently.
The above set of requirements for qualification to wear the Air Crew Insignia were modified several
times. BuPers Circular Letter Numbers 173-43 of 8 September 1943, 22-44 of 29 January 1944 and 174-44
of 16 June 1944 all make modifications to the qualifications but do not give a detailed description of the
BuPers Circular Letter Number 395-44, dated 30 December 1944, provided a comprehensive description
of the Aircrew Insignia: “The Aircrew Insignia is a silver-plated or silver-color, winged, metal, pin, with
gold-color circular shield with surcharged foul anchor, superimposed on wing roots, with words “AIRCREW”
below circular shield; a silver-color bar over the circular shield with three threaded holes to receive three
gold-color combat stars when officially awarded. The insignia will measure two inches from tip to tip of the
wings: circle on shield 5⁄160; total depth of the shield from the top of the circle to the bottom of the shield
9⁄160. The Uniform Regulations of 2 May 1947 provided the following description of the Aircrew wings: “A silver-
plated or silver color, winged, metal pin, with gold circular shield surcharged with foul anchor, superimposed
on wing roots, with word ‘AIRCREW’ in raised letters on a silver-color background below the circular
shield; above the shield there shall be a silver-color scroll; the insignia to measure 20 from tip to tip of the
wings; circle on shield 5⁄160 in diameter; total height of the shield and silver background beneath the shield
9⁄160. The scroll shall be 1⁄80 wide and 3⁄40 long and shall be centered over the wings. Gold stars to a total of
three, as merited, shall be mounted on the scroll, necessary holes being pierced to receive them. A silver
star may be worn in lieu of three gold stars.”
