News From Antiwar.com U.S. Air Force and Polish government sources confirm that American F-15 and F-16 fighter jets have arrived in Poland for joint exercises with host country aircraft; as a Radio Poland report phrases it, “amid concerns over a Russian troop build-up on the border with neighbouring Ukraine.” The exercises are preplanned though the message they send against the backdrop of Ukrainian-Russian tensions can’t be misinterpreted. Polish Defense Minister Mariusz Błaszczak announced that several dozen of the F-15 Eagles and F-16 Fighting Falcons landed at Polish airfields and will operate out of air bases in Lask and Krzesiny. The warplanes were accompanied by C-130 military transport planes. U.S. fighter jet squadrons typically consist of twenty-four planes each.
