Which of the following is included in our nuclear weapons systems?

The inclusion of Intercontinental Ballistic Missiles (ICBMs) and nuclear-capable bombers in our nuclear weapons systems is accurate because these platforms are critical components of a nation’s strategic deterrent capabilities. ICBMs are designed to deliver nuclear warheads over long distances, usually from fixed launch sites, providing a reliable second-strike capability. Nuclear-capable bombers add flexibility to the nuclear arsenal by allowing for global reach and the potential to deliver both nuclear and conventional payloads. Together, they create a credible deterrent, enhancing national security and stability.

In contrast, submarine-launched ballistic missiles, while also an important element of nuclear deterrence, represent a different category of delivery systems and are not included in the answer choice. Drone warfare technologies and advanced surveillance systems, although significant in modern military operations, do not fall under the classification of nuclear weapons systems, as they typically pertain to conventional warfare and intelligence-gathering respectively. Hence, option B is the most comprehensive and directly relevant answer to the question about nuclear weapons systems.
