In 1994 the Wright Laboratory in Ohio produced a three-page proposal of a variety of possible nonlethal chemical weapons, which was later obtained—complete with marginal jottings and typos—by the Sunshine Project through a Freedom of Information Act request.
In one sentence of the document it was suggested that a strong aphrodisiac could be dropped on enemy troops, ideally one which would also cause "homosexual behavior". The aphrodisiac weapon was described as "distasteful but completely non-lethal". In its "New Discoveries Needed" section, the document implicitly acknowledges that no such chemicals are actually known. The document also included many other off-beat ideas, such as spraying enemy troops with bee pheromones and then hiding numerous beehives in the combat area.
Wright Laboratory won the 2007 Ig Nobel Peace Prize for "instigating research & development on a chemical weapon--the so-called 'gay bomb'--that will make enemy soldiers become sexually irresistible to each other." However, Air Force personnel contacted were not willing to attend the award ceremony at Harvard University's Sanders Theater to accept the award in person.
Right off the bat, I guess I should add that additional research on my part shows that no money was actually spent on this batshit insane idea. I can barely believe that someone sketched together a research proposal for something like this. Still....just think for a moment what society would be like if such a chemical weapon actually existed. Larry Craig could have claimed he was the victim of a gas attack in the bathroom. 'OMG! I swearz I wuz gayBOMBED!' I can just imagine the whacky internet conspiracy theories that would pop up. It wouldn't surprise me at all if the sale of gasmasks went up in the aftermath.
