"In a unique spin on regularly recurring Bomber Task Force (BTF) missions in Europe, six US Air Force B-52 Stratofortress strategic bombers will fly over all 30 NATO nations in Europe and North America on Aug. 28," the statement read.
Later in the day, NATO Secretary-General Jens Stoltenberg said that the US bombers would be accompanied by dozens of aircraft of the alliance member states.
"Today the US shows their powerful commitment to #NATO with six B-52 bombers overflying all 30 Allies. They will be accompanied by dozens of aircraft from across the Alliance. Working together, we fulfil our core mission: to deter aggression, prevent conflict & preserve peace," Stoltenberg wrote on Twitter.
The single-day mission is called Allied Sky and aims to "demonstrate NATO solidarity, enhance readiness and provide training opportunities aimed at enhancing interoperability for all participating aircrews."
