Just a random thought....
What if someone in the Navy looked at the 1.1 inch gun and thought about adapting it to a Hotchkiss revolving cannon and adding a motor drive...sort of predating the Vulcan by about 15-20 years...
Would this have a basis for an improved AA gun design that was far more reliable?
