Arcanum,
The secret is in the way the USN operate. They complete a full combat work up at Fallon as an air group and then deploy to sea for 6-12 months. Once carrier qualified all flying is conducted "from the sea" so they maintain day and night currency. That is combat continuation training is conducted from the sea not a shore base. They will deploy ashore to a fixed airfield for short periods but the bias is totally towards sea operations rather than vice versa - this is the way the RN FAA operated until the RAF took control of the operational cycle where their ethos was (understandably) to operate from a fixed land base. This will have to change in the future.
