Which of the following is NOT considered an Air Force contribution to nuclear operations?

The correct choice, which indicates that attack helicopters are not considered an Air Force contribution to nuclear operations, is based on the specific role and capabilities of the various platforms listed.

Bombers, such as the B-52 and B-2, play a direct role in nuclear deterrence and have the capability to deliver nuclear weapons, making them essential components of the Air Force’s nuclear operations. Tankers are also crucial; they provide aerial refueling, extending the operational range of bombers and contributing to the flexibility and readiness of nuclear forces. Missile launch systems, which include intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs), are core elements of the nuclear triad and are vital for the strategic deterrence posture.

In contrast, attack helicopters, while important for conventional combat operations and support missions, are not designed or utilized for nuclear delivery or operations. Therefore, they do not contribute to the Air Force's nuclear operational capabilities. Understanding the specific roles of each platform clarifies why the selected answer is logically consistent with the definitions of contributions to nuclear operations by the Air Force.
