In seperate statements on Facebook, President Volodymyr Zelensky announced he had signed agreements with Estonia, the Netherlands and Denmark at a NATO summit in the Turkish capital Ankara. The drone deals create “new opportunities for joint production, the development of innovative defense technologies, systematic exchange of expertise, and the export of Ukrainian battlefield-proven solutions,” Zelensky said. Ukraine had already signed similar agreements with six other countries including Qatar, the United Arab Emirates and EU members Lithuania and Latvia. Zelensky announced plans to sign further deals with Germany, Norway, Finland and Canada. Kyiv does not typically release the terms of the deals. Ukraine has invested heavily in its drone industry since the war began, developing both attack drones and interceptor drones that it says are world beating. Both Moscow and Kyiv use drones extensively on the battlefield, firing thousands at each other since Moscow invaded its neighbor in 2022.
