The Drone DatabookCEASED in SPRING 202 but still has some useful information.
This is a study of military drone capabilities with profiles of 101 countries – as well as two appendixes that address military drone infrastructure and the technical specifications of more than 170 drones currently in use. Military drone capabilities of each country are evaluated in terms of six categories: inventory and active acquisition programs, personnel and training programs, infrastructure, operational experience, aircraft research and development programs, and exports.
