Which of the following aircraft is specifically designed for refueling other aircraft?

The Voyager is specifically designed for the role of aerial refueling. This advanced multi-role tanker transport aircraft is capable of refueling a variety of aircraft in flight, enhancing operational flexibility and extending the range and endurance of combat and support aircraft in the field. It is equipped with state-of-the-art technology that facilitates this function efficiently, ensuring that mission profiles can be sustained over longer durations without the need for landing to refuel.

In contrast, while the Atlas and Globemaster 3 serve important logistical and transport roles, they are not primarily tailored for refueling. The Atlas is known for its capabilities in rapid air mobility, tactical lift, and transport operations, whereas the Globemaster 3 is typically used for strategic airlift missions. The Shadow aircraft, on the other hand, serves a different purpose related to intelligence, surveillance, and reconnaissance (ISR) rather than aerial refueling.
