Nuclear submarines carry more firepower than all bombs dropped in history; since the 1950s, these steel vessels became U.S. defense cornerstones, sparking Cold War underwater competition and creating engineering miracles for deterrence.

Wartime research and development have revolutionized communication, transportation, and medicine; from Spam to nuclear power to hairspray and cell phones, life as we know it ironically owes a lot to war.

Tiny weapons may not sound impressive, but small can kill, and it can also be easily concealed; from a pocket pistol used by the police to a submachine gun wielded by a bodyguard, many of today's most effective weapons are smaller than ever.
