Quite correct. Hitler had an unusual fascination, one might say obsession for exotic and strange weaponry.
Hitler’s greatest asset in WWII were the military minds who made up his general staff and his leading panzer commanders-—men whose advice and counsel he routinely ignored-—another major reason Germany lost the war.
A fascination shared, curiously enough, by Churchill: who spent a remarkable amount of time and energy pursuing sometimes quite bizarre projects - some of which worked, others didn't.
