Gerald Vincent Bull (March 9, 1928 – March 22, 1990) was a Canadian engineer who developed long-range artillery. He moved from project to project in his quest to economically launch a satellite using a huge artillery piece, to which end he designed the Project Babylon "supergun" for Saddam Hussein's government in Iraq.
Bull was assassinated outside his apartment in Brussels, Belgium, in March 1990. His assassination is believed to be the work of the Mossad over his work for the Iraqi government. No person has ever been charged with his murder.
