During a Russian missile attack on Ukraine, Polish radar picked up an unidentified object inside national airspace. Neither the American F-15s nor the Polish MiG-29s airborne nearby could identify it before it vanished from the screens. The wreckage surfaced only on 27 April 2023, when a horse rider found the remains of a Kh-55 cruise missile in a forest near Bydgoszcz in northern Poland — close to NATO's Joint Force Training Centre. The four-month gap, and the fact that radar had lost the missile entirely, caused a lasting political controversy in Warsaw.
An Italian Eurofighter on NATO Baltic Air Policing duty destroyed an unidentified drone over eastern Latvia before dawn on 14 August, the second time the alliance's quick-reaction force has shot one down over the country this year.
