What is an important factor to monitor for MK 21 delay elements during storage?

Monitoring moisture buildup is crucial for the MK 21 delay elements during storage because moisture can lead to degradation and potential failure of the electronic components. Exposure to humidity or water can compromise the insulation and functionality of the delay element, which can cause an unsafe condition when the element is ultimately deployed. Therefore, ensuring that the storage environment is kept dry is essential to maintain the reliability and safety of these munitions.

In this context, it is essential to emphasize the significance of maintaining a controlled environment to prevent moisture-related issues, which can adversely affect performance and safety. The effectiveness of delay elements relies not only on their design but also significantly on how well they are stored and protected from environmental contaminants like moisture.
