Tokyo-based Terra Drone is expanding its investment in Ukrainian interceptor drones as it looks to bring battlefield-tested technology back to Japan to tap into a multibillion-dollar defense budget for unmanned systems.

On Tuesday, Terra Drone CEO Toru Tokushige said the company was entering a new strategic partnership with Ukraine¡¯s WinnyLab to develop fixed-wing interceptor drones. It comes after the company announced in March that it would make an investment in Ukraine¡¯s Amazing Drones to develop vertical take-off interceptor drones. Financial details weren¡¯t disclosed.

¡°Starting with interceptor drones we are looking for products that are good for increasing the defensive power of Ukraine and also the defensive power of Japan,¡± Tokushige said in an interview.
