In 1942, American dental surgeon Lytle S. Adams was contemplating bats. As World War II raged on around him he looked into bats as a possible weapon, some kind of animal attack that could no doubt be harnessed in the fight, specifically the Empire of Japan. Four potentially useful biological features of bats were noted, each of which was essential to producing one of the least known, yet most deadly products of the war.
Firstly, they could be found in huge numbers in Texas. This would mean they could easily be ‘mass produced’ as a weapon. Secondly, they could carry more than their own weight in-flight – females can even fly whilst carrying twins. Thirdly, bats can hibernate and during this do not need food or indeed any kind of sustenance or maintenance. If this could be harnessed, they could be made dormant and stored for large lengths of time, then awakened and unleashed on an unsuspecting enemy. Lastly, they fly in darkness and seek out buildings in the day time, meaning that they are both a stealth weapon and would home in on vulnerable buildings. Along with this, bats held other natural advantages. They could defy conventional detection systems. They were difficult to destroy using existing air defences and could easily navigate the confines of cities. With these advantages, he came up with the perfect way to weaponise bats; and so he created the bat-bomb.
