The U.S. Air Force will complete its fifth rotation as the lead nation for the NATO Baltic Air Policing mission on Jan. 8, 2018. On Jan. 5, videos documenting their efforts during their four-month deployment were publicly released.

The first one occurred on Nov. 23, and was initiated because the Russian aircraft did not broadcast the appropriate codes required by air traffic control and had no flight plan on file. The second one shows two Russian Navy Su-30s intercepted on Dec. 13, 2017. The second intercept was initiated for the same reasons: the Russian aircraft did not broadcast the appropriate codes required by air traffic control and had no flight plan on file.

“Intercepts are a regular occurrence, and U.S. Air Force pilots routinely conduct them in a safe and professional manner,” Lt. Col. Cody Blake, commander of the 493rd says in an interview included in the compilation. “Pilots from the 493rd Expeditionary Fighter Squadron executed the intercept professionally and operated in international airspace in accordance with all relevant international flight regulations and safety standards.”
