Official Description

Underway Replenishment (UNREP) systems are used to transfer cargo and liquid (i.e., fuel, water) at sea between U.S. Navy ships. A tensioned line is rigged between the two ships, and the cargo/liquid is transferred along the highline between the ships. Delivery ships (i.e., T-AKE, T-AO, and T-AOE) have the equipment used to transfer the cargo and fuel, while the receiving ships (i.e., combatants, carriers, amphibious) have a simple connection point to connect the line from the delivery ship and ...

Q1 received detailed technical answer clarifying static/dynamic load test requirements from S9086-TK-STM-010 Rev 5 (50,000 lb highline, 37,500 lb sliding padeye tests, specific angles). Also clarified: tester must provide own ballast/reaction structure; AI control acceptable; trainer needs load transfer capability only, not full UNREP evolution simulation.
