He designed various ballistics missiles, shells, and their delivery system, for which he is considered "father" of the mobile ICBMs, having created the RT-21 Temp 2S (SS-16), RSD-10 Pioneer (SS-20) and the RT-2PM Topol (SS-25).

Two years later Nadiradze began working in the Central Aerohydrodynamic Institute (TsAGI) in which he led a team of engineers engaged in theoretical and experimental research of aircraft landing gears based on the principles of air cushions.

In 1945 he got appointed chief designer and chief of the bureau of the Faculty of Missile weapons Moscow Mechanical Institute of the People's Commissariat of ammunition, functioning as experienced OKB guide holding lectures on the production and designing of missiles and launchers, while simultaneously conducting research on two-stage rockets and turbojets.

In 1948 the Council of Ministers of the Soviet Union transferred the Moscow OKB institute to CB-2 Minelhozmasha and Nadiradze took command over a division which was developing unguided anti-aircraft missiles and anti-tank rockets.

His experience was used to create the world's first high altitude meteorological rocket, development of which technically began back in 1949 at the Central Aerological Observatory Hydrometeorological Service of the USSR.

Nadiradze was appointed the head of Chelomey's secret development section and in 1961 took charge of the entire OKB, while remaining a chief designer.

By decision of the Soviet government and defense ministry a competition for designing a mobile intercontinental ballistic missile (ICBM) was organized and Alexander Nadiradze's team won.

This secret launch site was under command of the fellow Georgian Lt.General Galaktion Alpaidze who was in charge of the Soviet missile program and from 1975 was also a deputy director of the Moscow Institute of Thermal Technology.

For his third great achievement in Soviet missile technology Nadiradze was awarded Hero of Socialist Labour (gold medal with hammer and sickle) and Order of Lenin.

The RT-2PM Topol whose development started by Nadiradze in 1977, was put into active service in 1988, and to this day remains a primary nuclear strike capability of the Russian Federation.
