Doolittle approved the plan for Operation Aphrodite on 26 June, and assigned the 3rd Bombardment Division with preparing and flying the drone aircraft, which was to be designated BQ-7. The USAAF also planned to outfit war-weary B-24 Liberators with explosives and automatic pilots to be used against defended targets in Japan, under the designation BQ-8. Final assignment of responsibility was given to the 562nd Bomb Squadron at

Service history

It was hoped that Operation Aphrodite and Operation Anvil would match the British success with Tallboy and Grand Slam ground penetration bombs but the project was dangerous, expensive and ultimately unsuccessful. Of 14 missions flown, none resulted in the successful destruction of a target. Many aircraft lost control and crashed or were shot down by flak, and many pilots were killed, though a handful of aircraft scored near misses. One notable pilot death was that of Lt Joseph P. Kennedy, Jr., USNR, the elder brother of future US President John F. Kennedy. The program effectively ceased on 27 January 1945 when General Spaatz sent an urgent message to Doolittle: "Aphrodite babies must not be launched against the enemy until further orders".
