Who coined the term "Tin Can" in reference to
destroyers and when did it happen??
Tincan – Also seen as "Tin Can," a common nickname for a destroyer. The nickname arose because in World Wars One and Two, the hull plating of this ship type was so thin the sailors claimed they were made from tin cans. In fact, a .45 pistol bullet would penetrate it. Modern destroyers have much thicker hull plating, but the nickname persists. This nickname is sometimes abbreviated as "Can", although to a radioman a ‘can’ is a set of headphones.
