A U.S. Navy F/A-18 Super Hornet takes off from RAF Lakenheath, England, in 2018, during an exercise hosted by the base's 48th Fighter Wing. German Defense Minister Annegret Kramp-Karrenbauer said Wednesday that her country is in preliminary talks but hasn't yet committed to buying 45 F/A-18s to replace some of its aging Tornado fighter-bombers.
