to a deployment or to a fleet squadron? It'd probably take somewhere between 2.5-4yr to get to a fleet squadron. From there it will depend on where in the deployment cycle your squadron is. I deployed 6wks after checking in to my fleet squadron but i'm not sure you could do that anymore unless you were sent to a squadron at sea, which used to be rare.
I'd say that's somewhat common now, at least in my community. We had 2 or 3 folks fly out to meet us on deployment, fresh from the FRS.
Here's my timeline as a helo pilot:
-May-Nov 2010 - Stashed at USNA waiting for flight school
-March 2011 - Completed API
-October 2011 - Completed Primary
-July 2012 - Completed Helicopter Advanced
-April 2013 - Completed MH-60S FRS
-May 2013 - Got on USS Aircraft Carrier for an air-wing pre HARP/FARP CQ det for 2 weeks
-Rest of time until Summer 2014 - Workups. I was actually feet dry in the sate of CA for a total of 49 days in all of 2014.
Summer 2014 - Summer 2015 - Deployed on USS Aircraft carrier.
So, from commissioning? Just over 4 years in my case. To the "fleet?" Just under 3. With that said - I asked to go to Flight School late since I knew there were delays down in Pensacola at the time and I figured an extra summer in Annapolis wasn't the worst thing in the world. I enjoyed my job there too, and provided me with one of the most relevant things on my current resume to civilian employment.
