Which method does the US Navy use for UNREP?

The US Navy employs the STREAM (Standard Tensioned Replenishment Alongside Method) for Unrep (Underway Replenishment) operations due to its efficient and reliable design. This method allows vessels to transfer fuel and supplies while maintaining speed and course, which is critical for operational readiness and logistical support at sea.

STREAM involves a tensioned line that is maintained between the supply ship and the receiving vessel, allowing for the safe and controlled transfer of liquids. This system ensures that the connection remains stable despite the motion of both ships, which is essential when conducting operations under varying sea conditions.

This method has largely replaced earlier replenishment techniques because it minimizes risk during transfers and increases the speed and safety of operations. It provides a highly organized and effective means of logistics support during naval operations, helping to ensure that vessels remain combat-ready without significant interruptions in their missions.
