Which type of aircraft is NOT categorized under USAF major weapon systems?

The classification of major weapon systems in the United States Air Force (USAF) typically includes various types of aircraft that are designed to fulfill specific operational roles within air warfare. Fighter/attack aircraft, ISR (Intelligence, Surveillance, Reconnaissance) aircraft, and bomber aircraft are all integral components of the USAF’s operational capabilities.

Fighter/attack aircraft are designed primarily for air-to-air combat and tactical air support. ISR aircraft gather intelligence and perform reconnaissance missions, playing a crucial role in battlefield awareness. Bomber aircraft, on the other hand, are built to conduct strategic bombing missions against enemy targets.

In contrast, ground attack vehicles, which are not aircraft, do not fall within the category of major weapon systems of the USAF. Ground attack vehicles are typically associated with ground forces, such as the Army and Marine Corps, and are utilized for land-based combat operations rather than aerial warfare. Therefore, identifying ground attack vehicles as not fitting into the USAF major weapon systems highlights the distinction between air and ground military capabilities.
