What best describes compatibility group F?

Compatibility group F encompasses items that have explosive trains with less than two effective protective features. This classification is important because it defines the safety margins required when handling, storing, or transporting items within this group. The lack of multiple protective features means these explosives might have a higher risk of initiating inadvertently due to certain conditions, thus necessitating stricter safety protocols to mitigate hazards.

Other options describe characteristics that do not accurately reflect compatibility group F. For instance, items with high explosive content (as noted in another choice) could belong to various groups based on their specific attributes and applications, while stability at high temperatures or underwater applications pertain to different compatibility group designations entirely. Understanding these distinctions is crucial for maintaining safety within explosive handling and storage practices on aircraft carriers.
