'Missile Strike Carried Out With Yemeni Cooperation'—Using UCAVs to Kill Alleged Terrorists: A Professional Approach to the Normative Bases of Military Ethics

Abu Ali al-Harithi, reportedly a right-hand man to Osama Bin Laden, is alleged to have been responsible for planning the October 2000 bomb attack on the US Navy’s Arleigh Burke-class destroyer USS Cole in which 17 US sailors died. An unmanned combat aerial vehicle (UCAV) attacked his car filled with suspected Al Qaeda members in a remote desert area in Yemen. It is believed that Abu Ali al-Harithi and five other people were killed in the attack (Pincus 2002). The action is understood to have taken place with at least Yemeni knowledge, if not approval. Unmanned aerial vehicles (UAVs) or drones have been around for 40–50 years, but until recently it was an immature technology. The US Central Intelligence Agency’s (CIA’s) air strike in Yemen has demonstrated the UCAV’s transition from a surveillance drone to a hunter—killer asset. With this dramatic proof of concept, several aerospace companies are developing UCAVs. Two characteristics make the UCAV a system of choice: low cost and the fact that humans are not put at risk.
