ChD you hit the nail on the cranium, Comstrattelmuelinknav.. what is up with that.
BTW, THe oldest Fighter squadron in the Air Force is the 27th Ftr Sqd at Langley, they will also be the first to get the F/A-22 frontline.
The flying Units numbers are all based on mainly history as noted above.
Other Units take the number of the parent Wing and/or group.
I.e. the 72 ABWing has the 72d Security forces sqd, 72d Services sd, Finance etc etc. The flying and test units will have different numbers.
It is a simple system Wing, Group, Squadron (then flights within Sqds most often). Example I am in the 552 Air Control Wing, 552 Ops Group, 964th AACSqd, etc etc. We are under Air Combat Command, 8th Air Force also.
Deployed Units will take Expeditionary unit numbers.
Ciao, and Hook 'em Horns,
