On a normal deployment we would top our escorts off every 3-4 days. Several factors go into a refuel, the ships commanding officer, the battle group commander and logistics. When I was on Independence (oil burner) we only topped off our escorts as needed, but were refueled every 3 days ourselves.
Interesting. Thanks for the info. Underway replenishment is not something I’ve thought about in a long time. Back when we were all young.
