From which of the following sources can the AAFS receive fuel?

The AAFS, or Afloat Aviation Fuel System, can receive fuel from multiple sources to ensure operational flexibility and sustainment. Receiving fuel from 55-gallon drums, tanker trucks, and host nation facilities provides a diverse capability that allows the AAFS to maintain an adequate supply of aviation fuel under various circumstances.

55-gallon drums are commonly used for transporting and storing fuel, especially when smaller quantities are required or when access to larger refueling sources is limited. Tanker trucks facilitate the movement of larger volumes of fuel and can be deployed to remote areas where other distribution methods might not be available. Host nation facilities enable cooperation and logistics support from allied nations, allowing for the procurement of fuel resources that might not be accessible solely through domestic military channels.

In contrast, the other options are limited in scope and applicability. Relying only on Navy supply ships restricts the AAFS's ability to operate in non-naval environments. Solely depending on military installations does not account for the necessity of fuel logistics in various operational theaters, especially in joint or multinational operations. Public gas stations and commercial trucks are not a reliable or secure means of obtaining military-grade aviation fuel, which must meet specific standards for quality and performance required by military aircraft.
