The Wright Laboratory (now called the Air Force Research Laboratory) of the United States Air Force submitted a proposal on June 1, 1994 titled "Harassing, Annoying, 'Bad Guy' Identifying Chemicals" which describes several concepts for non-lethal chemical weapons, including one composed of aphrodisiacs intended to cause homosexual behavior:

"Capability Sought and Uses to Which It Could Be Put: Chemicals that can be sprayed onto enemy positions or onto infiltration routes used by enemy forces. Three classes of chemical weapons are proposed: ...

Category #3: Chemicals that effect [sic] human behavior so that discipline and morale in enemy units is adversely effected [sic]. One distasteful but completely non-lethal example would be strong aphrodisiacs, especially if the chemical also caused homosexual behavior...

Chemicals that effected [sic] human behavior in ways that would be disruptive to unit morale and effectiveness would need to be created."

Hank Plante, a news reporter for CBS 5 KPIX TV, the San Francisco affiliate of the CBS television station, explained in his June 8, 2007 "Pentagon Confirms It Sought To Build A 'Gay Bomb'":

"A Berkeley [California] watchdog organization that tracks military spending said it uncovered a strange U.S. military proposal to create a hormone bomb that could purportedly turn enemy soldiers into homosexuals and them more interested in sex than fighting.

Pentagon officials on Friday confirmed to CBS 5 that military leaders had considered, and then subsequently rejected, building the so-called 'Gay Bomb.'

Edward Hammond, of Berkeley's Sunshine Project, had used the Freedom of Information Act to obtain a copy of the proposal from the Air Force's Wright Laboratory in Dayton, Ohio... The documents show the Air Force lab asked for $7.5 million to develop such a chemical weapon...

'The Ohio Air Force lab proposed that a bomb be developed that contained a chemical that would cause enemy soldiers to become gay, and to have their units break down because all their soldiers became irresistably attractive to one another,' Hammond said after reviewing the documents. 'The notion was that a chemical that would probably be pleasant in the human body in low quantities could be identified, and by virtue of breathing or having their skin exposed to this chemical, the notion was that soldiers would become gay...'

A DOD [U.S. Department of Defense] spokesperson... indicated that the 'gay bomb' idea was quickly dismissed. However, Hammond said the government records he obtained suggest the military gave the plan much stronger consideration than it has acknowledged... Military officials insisted Friday to CBS 5 that they are not currently working on any such idea and that the past plan was abandoned."
