Tactical nuclear weapons were a large part of the peak nuclear weapons stockpile levels during the Cold War. US scientists with a full-scale cut-away model of the W48, a very small tactical nuclear weapon with an explosive yield equivalent to 72 tons of TNT (0.072 kiloton). Around 100 of such shells were produced during the Cold War.
