What Protection Level (PL) is assigned to aircraft loaded with nuclear weapons?

The assigned Protection Level (PL) for aircraft loaded with nuclear weapons is PL1. This is because PL1 is designated for resources that require the highest level of security due to their critical nature, specifically those involving nuclear weapons. The rationale behind this classification lies in the potential consequences of unauthorized access or use of nuclear weapons, which could lead to catastrophic outcomes.

Consequently, aircraft carrying these weapons are subject to stringent security measures, ensuring a robust protection framework against any threats. The higher Protection Levels ensure that the most sensitive materials are guarded with the utmost vigilance and resources.
