Which aircraft is designated as the E-2?

The E-2 designation refers specifically to the Hawkeye, which is an aircraft used primarily by the United States Navy. The Hawkeye serves as an airborne early warning and control platform, equipped with a distinctive radar dome that provides surveillance and reconnaissance capabilities. Its primary role includes gathering intelligence, tracking air and surface targets, and coordinating missile defense efforts.

The variable capabilities of the Hawkeye make it a crucial asset within carrier strike groups, enhancing situational awareness and conducting command and control operations. The aircraft is designed to effectively operate in various environments, making it vital for naval operations.

In contrast, the other aircraft listed do not hold the E-2 designation or fulfill similar operational roles. Each of those has their unique functions and specifications but does not align with the characteristics or duties associated with the E-2 Hawkeye. This distinction underlines the pivotal role that the E-2 plays in modern naval aviation and its unique designation within the military aircraft classification system.
