Blue-21 has been around several years. For Blue-21, you do need a PPL.
I've been in 16 1/2 years, 10 years was Enlisted (Yeoman). I'm at my fourth Air Station ... I've never met a DC Aviator that came in any higher than a JG. I'll ask the DC's at work tomorrow.. pretty sure they're all coming in as ENS's. Heck, we have a Army Major (O-4, right?) Select that is now a LTJG in the CG ... he's been in a few years.

Those applicants who are selected to the DCA program, all Warrants and O-1's and O-2's will be commissioned in the Coast Guard as Ensigns (O-1). All O-3's and above will be commissioned in the Coast Guard as Lieutenants Junior Grade (O-2)."
Well, there isn't any "classic" Coast Guard aviator...
As many know here, I happen to have no degree.. only ever attended one college class. But, I busted my ass to make E-6, get selected for OCS, and 4 years after that, flight school.
But our Academy grads have always had to go to a ship for 18-24 months before going to flight school.. ALL of them had to. Last couple of years, we haven't had enough ship billets for them so there are some going straight from the Academy to Flight School.
OCS.. either have a 4 year degree, OR, be E-5 or above w/4 years of CG service, 30 S/H college and 1 college level math class.. Our OCS classes are tpyically 40ish people.. give or take. Anywhere from 2 to 8(???) will get selected for flight school. You can apply again out in the "fleet" if you dont get selected in OCS. We usuallly have 2 to 3 OCS Classes a year.
My unit also has a two DC's from the Merchant Marine Academy.. one guy was a prior reserve enlisted who got a conditional release to attend Kingspoint.. he graduated and joined the CG under a DC program we've had for years.. applied for flight school, whalla. The other guy went to a Marine Safety Office after his DC school then applied for flight school.
There is no cookie cutter officer or aviator in the Coast Guard. The Coast Guard recognizes performance as much as they do education. We are probably half and half.. half Coast Guard Academy ... half OCS ... with half the OCS'ers having prior service.
My unit there is another former Yeoman, a two former Boatswain's Mates, former Navy Rescue Swimmer, and the lsit goes on and on.
