Four U.S. Air Force F-16C Fighting Falcons and four Swedish Air Force JAS 39 Gripens fly in formation together behind a U.S. Air Force KC-135 Stratotanker during aerial refueling training in Swedish airspace, Feb. 8, 2018.
The air refueling training is in conjunction with a rotational deployment of F-16Cs from the Ohio Air National Guard’s 180th Fighter Wing to Amari Air Base, Estonia, as part of a Theater Security Package. The training allows the U.S. and Sweden to strengthen interoperability and increase readiness. (U.S. Air Force photo by Airman 1st Class Luke Milano) Original public domain image from Flickr
