What function do Combat Logistics Type ships primarily perform?

Combat Logistics Type ships are primarily designed to conduct underway replenishment for fleet units. This means they provide essential supplies, such as fuel, munitions, food, and equipment, to ships operating at sea. The capability to replenish ships while they are underway is crucial for maintaining naval operational readiness and extending the reach of naval forces without requiring them to return to port.

Underway replenishment enhances mission continuity and operational flexibility, allowing the fleet to stay on station longer and respond to missions without interruption. Other options like amphibious assaults, mine warfare, and coastal support operations do not reflect the primary function of these specialized vessels, which focus specifically on logistics and supply chain management at sea.
