In which configuration can the safety clip be reinstalled for the BDU-33B/B?

The safety clip for the BDU-33B/B can only be reinstalled in configurations that include the CXU-2/B spotting charge. This is because the design and safety features of the BDU-33B/B are tailored to ensure that the safety clip effectively prevents accidental detonation during handling and transport when a spotting charge is in use. The CXU-2/B is specifically meant to serve as a non-explosive device that allows the munition to function safely in training scenarios.

In contrast, the other configurations, such as those with a regular charge or a heavy charge, may lack the necessary safety features that work in conjunction with the safety clip, potentially increasing the risk of accidents. Thus, the design intends for the safety clip to be applied only in situations where the conditions are controlled and suitable, ensuring safe usage within the designated parameters of this specific munitions system. This restriction reflects the importance of adhering to safety protocols in munitions handling.
