Nie codziennie 12 sztuk B-2 wzbija się razem w niebo
That’s exactly what happened at Whiteman Air Force Base, Missouri, on April 15, when a dozen B-2s took part in a mass fly-off exercise. This was so many of the bombers that none of the official pictures from the event, seen at the top of this story and below, show all 12 aircraft at once. This represents the majority of the total number of B-2s currently operated by the Air Force, which stands at 20 aircraft, per the service, although one is damaged during a landing incident at the base and another is still undergoing repairs from a similar incident. Of that number, typically only 11 or 12 are actually “deployed” under the terms of the New START treaty with Russia and are available for combat missions.
