The United Kingdom’s Ministry of Defence released its much-anticipated inaugural space policy paper “Defence Space Strategy: Operationalising the Space Domain”. The U.K., the No. 1 ally of the United States, is a member of the European Space Agency and a signatory to the U.S. -led Artemis Accords. To understand Britain’s space security ambitions, Laura Winter speaks with Bleddyn Bowen, a space warfare expert at the University of Leicester, and the author of the book, “War In Space: Strategy, Spacepower, Geopolitics”, and with Juliana Seus, the Royal United Services Institute space security policy lead.
