Replenishment at sea is the term applied to the transfer
of fuel, munitions, supplies, and personnel from one

Replenishment at sea is accomplished with both the
replenishment ship and the ship(s) being replenished
steaming side by side on parallel courses at a
Figure 8-32.Replenishment at sea enables the fleet to remain at sea and make successive strikes without returning to base for
fuel, ammunition, and supplies.
