In the Fox News video one of the skippers mentioned their average time in the last 30 was 4 hours.
I'm pretty confident that DCA is acutely aware of issues such as those.
Also varies by workup/deployment cycle, as well as type of command and allocated funding. I've seen it both ways (in terms of flight hours), all during this period of hard times.
This is something that both the USN and USMC are looking closely at. The funding is key, which always results in tough decisions on who to play and who to bench.
