Which of the following is NOT a component of the TRIAD of strategic nuclear forces?

The TRIAD of strategic nuclear forces consists of three main components: intercontinental ballistic missiles, sea-launched ballistic missiles, and long-range bombers. These components work together to provide a credible and survivable nuclear deterrent for a nation, ensuring that if one element is compromised, the others remain intact to fulfill their deterrent role.

Intercontinental ballistic missiles (ICBMs) are land-based missile systems that can strike targets over long distances. Sea-launched ballistic missiles (SLBMs) are launched from submarines, offering stealth and the ability to remain concealed while providing a second-strike capability. Long-range bombers are aircraft designed to deliver nuclear weapons from a significant distance.

In contrast, aircraft carrier battle groups do not play a role in the TRIAD. While aircraft carriers are indeed important for naval power projection and can be equipped with aircraft that may have the capability to deliver conventional or nuclear weapons, they are not classified as a part of the strategic nuclear triad. Therefore, within the context of the question, aircraft carrier battle groups do not contribute to the strategic nuclear deterrence framework defined by the TRIAD.
