Passage: Vandenberg graduated from the United States Military Academy in 1951 (where Buzz Aldrin was one of his classmates). In 1953, Vandenberg was assigned to the 86th Fighter-Bomber Wing. Later he would serve as a flight commander with the 413th Tactical Fighter Wing and the 31st Tactical Fighter Wing. He graduated from the Air Command and Staff College in 1961, after which he was assigned to the 4th Tactical Fighter Wing. In 1963, Vandenberg was appointed Operations Officer with the 23rd Tactical Fighter Squadron. During the Vietnam War, Vandenberg commanded the 390th Tactical Fighter Squadron. Upon returning stateside he was assigned to The Pentagon to work in the Office of the Director of Plans. He would graduate from the National War College in 1969 and return to The Pentagon to work with the Joint Chiefs of Staff. In 1971, Vandenberg became commander of the 12th Flying Training Wing. Vandenberg was named Vice Commandant of Cadets at the United States Air Force Academy in 1972. He would serve as Commandant from 1973 to 1975, during which time he assumed the rank of brigadier general.

He was the great-great-great-great-grandson of poet Alexander Sumarokov and the Great Great Grandson of Field Marshal Mikhail Kutuzov. He was the nephew of tennis player Count Pavel Sumarokov-Elston, who was his first coach and doubles partner, grandson of Count-General Felix Sumarokov-Elston, Governor of Kuban Oblast, and cousin of the infamous Prince Felix Yussupov, who later became known as one of the collaborators who conspired to kill Grigori Rasputin, cult leader and mentor of Empress consort of Russia Alexandra. Felix provided his own palace for the murder spot and also shot Rasputin once before murdering him with the help of his accomplices. Mikhail had a sister called Elena and a brother Nicholas. At the age of twelve he had a surgery on his right hand, which as a result was rendered unsuitable for tennis and he later switched to left-hand play. First he moved to Dresden and was trained by Kurt Bergmann and George K. Logie. In 1906 he entered the second-class tournament of the Bad Homburg Championships, where he defeated Jack Hillyard amongst many to claim his first title. With this he set a record of being the youngest winner ever at the time in the history of the tournament. In 1908 his father and brother died within two weeks of each other. He moved back to his homeland and graduated first at the Annenschule then at the Law Faculty of the St. Petersburg University.
