All Air to ground precision stuff like GBU-10, gbu-12, GBU-28, etc.. all the laser guided stuff was tested by rockwell, boeing, now rockbowell:) and the air force. the famed AIM-9 was originally an Air force juncture that turned out good for all the services. Basically, if its carried by a fighter bomber, or an Air supiriority fighter, it was built to AF standards for the AF, and the navy bought it. There is a few exceptions, for example the AGM-154 pheonix, is purley a navy missile. The FA-18 was originally a platform that Macdonnel Douglas used to compete against Gen Dynamics F-16 for the AF's bid for a new fighter. The AF went with the falcon, but the NAvy saw promise in the FA-18.
BTW, thats a fancy name for your MOS, a term like chemist in the AF means a commision, or GS-11 or above.
We promote the same way it seems. We test and our duty performance and job knowledge (plus time in grade, time in service, decorations) play a role in our promotions. It is possible to sew on E6 before 6 years in the AF, but you must make it the first time for both E5, and E6.
I have a friend that was an E5 in 1990, he is now an E9. He has done well.
I always wondered this, how come they wont let you guys wear the nice uniform till your an E-7?
