Gdynia-Kosakowo Airport (also known as Gdynia-Oksywie or Gdynia-Babie Doły) is a civil (unfinished) and military airport in northern Poland. The governing authority of the city of Gdynia intended to build this airport as a low-cost alternative to the main airport at Rebiechowo, near Gdansk, providing another economic boost to the area.
The airport was built prior to World War II on the site of the former Amalienfelde farm as a diversion airport for the Rumia-Zagórze Airport, which closed in 1974. During the German occupation, Luftwaffe planes were stationed at Babie Doły Airport, conducting tests related to torpedoes. After the war, the area was taken over by the Polish Armed Forces.
