Two B-52 Stratofortress intercontinental strategic bombers of the US Air Force (capable of carrying various types of weapons, including nuclear ones) simulated "bomb drops" in close proximity to the Russian border, according to Bulgarian Military.
According to Bulgarian Military, this occurred after Russia's use of the "Oreshnik" missile. The bombers flew from the UK and conducted an "operation" over Finland.
It later became known that two Russian Su-27 fighters intercepted the American bombers over international neutral airspace. The Pentagon confirmed that the interception occurred without violating international rules.
The article emphasizes that the interception of American bombers by Su-27 fighters demonstrates the readiness of the Russian Aerospace Forces to defend their airspace. This is not the first time that Russian pilots have intercepted Western aircraft.
