The United States is to allow the transfer of Lockheed Martin F-16 Fighting Falcon combat aircraft to Ukraine, President Joe Biden announced on 19 May. The announcement, which reversed the president's earlier stated position that Ukraine did not need such jets, was made at the Group of Seven (G7) summit of world leaders in Hiroshima, Japan. “In my private meeting with [Ukrainian President Volodymyr] Zelensky I told him the United States, together with our allies and partners, is going to begin training Ukrainian pilots in fourth-generation fighter aircraft, including F-16s, to strengthen Ukraine's air force as part of a long-term commitment to Ukraine's ability to defence itself,” Biden said, adding that he had received an assurance from Zelensky that these aircraft would not be used against targets inside Russia.
