Not the bat bomb. I'm looking for pictures of the CAT bomb. It was an OSS project that attempted to use cats to guide bombs into axis ships. The premise was that cats hated water so much that if you packed them into a control harness within a bomb they would instinctively guide the bomb onto the deck of an enemy ship to avoid getting wet. The project was eventually canceled when in testing the OSS discovered that cats tend to pass out from G-forces when strapped into a 500lb bomb traveling at terminal velocity.
Bat bombs were an experimental World War II weapon developed by the United States. The bomb consisted of a bomb-shaped casing with over a thousand compartments, each containing an hibernating Mexican Free-tailed Bat with a small timed incendiary bomb attached. Dropped from a bomber at dawn, the casings would deploy a parachute in mid-flight and open to release the bats which would then roost in eaves and attics in a 20-40 mile radius. The incendiaries would start fires in inaccessible places in the largely wood and paper construction of the Japanese cities that were the weapon's intended target.
