During World War II, the United States worked to develop a “bat bomb” that consisted of an air dropped canister containing Mexican free-tailed bats with a small timed incendiary bombs attached to their tails. Work on the bat bomb was cancelled due to the development of the atomic bomb. Almost as strange as the “bat bomb” was a top secret operation, code-named “Project Seal“, which apparently came close to developing a “tsunami bomb.” The goal was to destroy coastal Japanese cities with man-made tsunamis. Testing was carried out in waters around New Caledonia and Auckland and showed that the weapon may have been feasible. A series of 10 large offshore blasts could potentially create a 33-foot tsunami capable of inundating a small city.
