How much oil can an AOE carry?

The correct amount of oil that an AOE (Fast Combat Support Ship) can carry is indeed 177,000 barrels. This capacity is significant as it allows the ship to support other vessels in a fleet operation by providing fuel and logistical supplies. The AOE typically serves the role of a mobile fueling station, enabling ships to refuel at sea, which enhances operational readiness and extends the range of naval forces without needing to return to port.

This capacity is carefully calculated based on the typical operational requirements of the naval fleet and is designed to meet the demands of modern naval engagements. Other figures presented in the options either significantly underrepresent or overestimate the logistical capabilities of an AOE, making the 177,000 barrels the accurate reflection of its oil-carrying capacity.
