I know that during OCS all candidates get very little sleep for weeks. The Navy as a whole is also known to overwork its sailors giving them little opportunity to sleep, especially amongst the SWO. But I've read online that NFOs and Aviators get a little more sleep than the rest. Is this true? Is there any sleep deprivation during flight school or afterwards for NFO/Aviators? Other than OCS, will they ever be chronically sleep-deprived?
