Soviet Su-7 jet drops live 11-kiloton nuclear bomb in 1962 test

The test occurred on August 27, 1962, at the Semipalatinsk site in present-day Kazakhstan, with pilot Lt. Col. A. I. Shein releasing the 244N bomb from a single-seat Su-7B.
The bomb detonated at 800 feet altitude, demonstrating the Su-7’s capability for tactical nuclear delivery using an over-the-shoulder toss maneuver and specialized PBK-1 bomb computer.
This rare air-dropped nuclear test helped validate Soviet tactical nuclear strike methods, influencing subsequent weapon developments and training, and remains significant as air-dropped tactical nuclear weapons continue to play a role in Russian military strategy.

RDS-4 "Tatyana" and the Evolution of Soviet Tactical Nuclear Weapons: From 1953 to the 1962 Su-7B Test
Overview
On August 27, 1962, the Soviet Union successfully tested a tactical nuclear strike using a Su-7B fighter-bomber performing a toss-bombing maneuver, proving that frontline aircraft could deliver nuclear weapons effectively and survive. This test built on earlier advances like the RDS-4 "Tatyana," the first mass-produced tactical nuclear bomb, which enabled widespread deployment across Warsaw Pact forces. Soviet Cold War doctrine relied heavily on such tactical nukes for rapid strikes against NATO, especially as NATO's growing conventional forces made a quick Soviet victory more difficult. However, extensive nuclear testing, particularly at Semipalatinsk, caused severe health and environmental damage, sparking movements that led to test site closure and Kazakhstan's leadership in nuclear disarmament.
