There are a lot of ways to win a battle, but the most effective methods involve some kind of surprise and deception. Sneak attacks go back as far as war itself, and since then we've come up with a lot of weapons designed to deliver damage without getting caught.On this list, we're going to take a look at some of the coolest, scariest, and most notorious sneak attack weapons in history, focusing on attack weapons - offensive weapons, not traps or ambush tactics. This list of stealth weapons is about those death-dealing sucker punches, those meant to take out a single target in silence or wipe out whole contents in a global doomsday scenario. Say what you will about the tactics, but one things for sure: these sneak attack weapons just don't know how to fight fair.
Horton HO 299 "Bat"
It's hard to believe, but this incredibly modern-looking stealth aircraft was captured by the Allies from Germany after WWII. Recently confirmed to have been built specifically for radar stealth using all-wood construction and radar-absorbing carbon glue, the crazy-fast jet-powered "Bat" never saw action.
At first glance, this German U-Boat looks like any other, which in a way already immediately classifies it as an epic sneak attack weapon. But U-480 was a stealth weapon among stealth weapons, being the first submarine in history ever to use a sound-absorbing, rubberized "anechoic" coating that made it almost invisible to sonar. Submarines still use this anechoic coating, and even 80 years later its exact composition remains classified information.
Poison Gun Umbrella
Among followers of shadow wars and spy games, this KGB killing tool has reached almost mythical proportions. Using compressed air to fire a tiny pellet of ricin toxin into its victim, the umbrella gun silently stung like a bee made of doom. Its most notable victim was Bulgarian journalist Georgi Markov, though likely nobody short of Vladimir Putin truly knows the umbrella gun's final body count.
Cigarette Dart Gun
Say what you will about the KGB, but they did come up with some pretty sweet spy toys. This pack of smokes concealed a clip of cyanide-tipped darts, and could silently kill its victim from across the room. The one pictured was remanded to the C.I.A. by a defecting Russian spy named Nikolai Khokhlov, whose original mission was to assassinate an anti-communist agitator in Germany.
