 The ships of military sea-lift command keep the fleet operational by keeping it fed and fueled. Petty Officer Kelby Sanders takes us aboard the Kaiser-class replenishment ship to show us how they keep the fleet stocked and ready to go. How does a U.S. Navy ship stay at sea for several months at a time with only a limited amount of supplies? The answer? A dynamic global force of civilian mariners. And our importance is we can keep the Navy on station. We can keep them in the fight so they don't have to worry about pulling in the port and getting the fuel and getting the food, we'll bring it to them. The military sea-lift command goes wherever the Navy's fleets operate to deliver fuel, supplies, and other mission-critical components the fighting ships need. The USNS Kanawa conducts underway replenishments by connecting fuel and cargo lines to the receiving ship or by airlifting cargo by helicopter.
