Which model aircraft corresponds to the designation E-3G?

The designation E-3G corresponds to the Airborne Warning and Control System (AWACS) aircraft, which is a modified version of the KC-135 Stratotanker. The E-3G variant specifically features upgraded radar and systems for improved surveillance and command-and-control capabilities.

The KC-135 is originally designed for air refueling missions; however, the modifications made for the E-3G allow it to conduct advanced tracking, data gathering, and enemy engagement monitoring operations. This makes the E-3G a vital asset for air operations, providing real-time information and directives over a wide area.

The other aircraft listed do not have the same capabilities or designations that align with the E-3G, which is specifically built for airborne surveillance and control, emphasizing the unique role of the KC-135 in this context.
