The United Kingdom launched an investigation into allegations that researchers at British universities have contributed to research that could aid Iran's military drone program. The investigation followed a report by the Jewish Chronicle that scientists at universities including Imperial College London and Cranfield University, which has a partnership with the UK Ministry of Defence, worked with Iranian counterparts to publish studies on drone engine performance and aircraft control systems. At least one of the studies, published in 2019, was supported by Iran's Ministry of Science.
