The Defense Innovation Unit (DIU), working with the Department of Defense’s Office of the Under Secretary of Defense for Acquisition & Sustainment (A&S), has selected four industry teams to develop and demonstrate long-range, one-way unmanned aerial systems (UAS) under Project Artemis. By combining rapid prototyping with operationally representative testing, Project Artemis aims to field systems capable of delivering strike effects or conducting intelligence, surveillance, and reconnaissance (ISR) in demanding conditions. Selected participants in Project Artemis include Swan—a U.S. software developer partnered with a Ukrainian UAS integrator—alongside with its own Ukrainian collaborator. Project Artemis also employs an expedited acquisition model. As prototypes reach maturity, Project Artemis will generate data on performance, reliability, and cost metrics in contested settings.
