When discussing nuclear weapons, what is meant by "complete assembly"?

The term "complete assembly" in the context of nuclear weapons refers to a fully functional unit capable of producing a nuclear reaction. This means that all necessary components, including the nuclear materials and any necessary mechanisms for detonation, are in place and operational. Complete assembly signifies that the weapon is not just a collection of parts but a cohesive and ready-to-use device that can achieve its intended destructive capability.

Understanding "complete assembly" as a fully functional unit highlights the complexity and engineering required to ensure that each component works together effectively. This is critical in the context of strategic stability and deterrence, as nations must be cognizant of the implications of nuclear capabilities that are fully assembled and operational.

Other choices may refer to aspects related to nuclear weapons but do not capture the specific idea of "complete assembly" as referring to a fully functional unit. For instance, a weapon ready for deployment encompasses broader operational readiness, while an apparatus requiring multiple components suggests a collection of parts rather than an operational unit. Similarly, an assembled package of nuclear materials lacks the emphasis on the functionality and readiness that define "complete assembly."
