RAS (Replenishment at Sea)

Replenishment at Sea (RAS) is a naval logistics operation where ships transfer fuel, supplies, and equipment while underway, without needing to dock. This process allows naval vessels to stay on mission longer by receiving essential resources from a supply ship. During RAS, one ship delivers cargo through hoses or lines, ensuring that military operations can continue efficiently without returning to port. This capability is vital for sustaining naval operations, especially during extended missions or in remote areas where access to land-based support is limited.
