Hi WClark, it’s possible, assuming they are possibly linked then there’s a million and one uses for such lockable Safety boxes on military ships, especially locks with dual locking control.
The use may not be so much like customers using one in a bank, but for maps, documents, codes, contraband, if not certain valuables and personal effects, the uses are still widespread.
It’s actually more common to see such ‘light-duty’ containers and boxes being used on military ships than massive 2-ton safes, as the risks are drastically contained and limited purely to those on board.
