Ahmad Nakhjavan became the first head of the Iranian Air Force and was the director of aviation with him until 1937. During this time he was changed several times and fired, but each time he returned to service after a short time. In 1929 he became a brigadier general. In 1940, he became the acting Minister of War in Ahmad Matin's cabinet, and in 1319, he was promoted to the rank of Major General. Nakhchivan was under the auspices of the Ministry of War until September 29, 1941, at the same time as the Soviet and British forces invaded Iran, and approved the plan to dismiss conscripts and recruit contract soldiers to members of the Supreme Army Council.

He was imprisoned until September 16 and became Minister of War on September 20, after the Shah resigned to restore Foroughi's cabinet. After that, he was an inspector and head of Mohammad Reza Shah's military office for some time and died in 1967.
