Octopus-100 is an interceptor drone of British manufacture. Thousands of units are planned to be mass-produced by the UK for Ukraine under the aegis of Build With Ukraine project, a production figure which speaks to the weapon's scalability and modularity (a design philosophy for rapid field deployment). [1] Technical specifications have not been officially released.
