Totsky Range (1954 Nuclear Exercise)

Totsky Range is a military range in the Totsky District of Orenburg Oblast, Russia, known as the site of the Soviet Union's only full-scale military exercise to use a real nuclear weapon. On 14 September 1954, a 40-kiloton atomic bomb was dropped here — more than twice as powerful as the bomb that destroyed Hiroshima. The exercise involved 45,000 troops, 600 tanks and self-propelled guns, 500 guns and mortars, 600 armored personnel carriers and 320 aircraft.

Timeline of the Blast

At 9:33 a.m. on 14 September 1954, a Tu-4 bomber crew, with Major Vasily Kutyrchev at the controls, released the bomb from an altitude of 8,000 metres. A few seconds later it detonated in the air at an altitude of about 350 metres; the bomb missed its intended aiming point by roughly 280 metres.

The blast produced a blinding flash and a fireball; temperatures at the epicenter are estimated to have reached 8,000–25,000 degrees. The shock wave threw the carrier aircraft up by 50–60 metres at a distance of 10 km, and the ground shook within a radius of up to 70 km. The mushroom cloud rose to 15 km, its stem 2.5–3 km wide, and trees near the epicenter were uprooted.

Exercise "Snezhok" (Snowball)

The operation was codenamed Snezhok ("Snowball") and commanded by Marshal Georgy Zhukov. Its goal was to rehearse an infantry, tank and artillery advance through a zone hit by a nuclear strike: just five minutes after the blast, troops began moving toward the epicenter with only minimal protective equipment.

Aftermath

The radioactive cloud drifted northeast and within hours passed over dozens of settlements in Orenburg Oblast. Residents of nearby villages were evacuated before the blast but were moved back afterward, into an area with elevated radiation levels.

Reports on the health of participants and local residents remain incomplete, and sources disagree. Veterans recalled headaches and vision and joint problems after the exercise; epidemiological data from 1985–1993 showed an increase in cancer cases among residents of nearby districts — according to a Novaya Gazeta investigation (2022), respiratory cancer rates rose by 225%, thyroid disease by 260%, and blood and lymphatic system cancers by 670%. Military officials, including General Yevgeny Zelentsov, maintained that these were ordinary illnesses unrelated to the exercise. Information about the exercise remained classified until the early 1990s; participants were officially recognised as having been "exposed to radiation" only in 1991.

Totsky Range Today

The range is still an active military site — a garrison is stationed there, and public access to the epicenter is restricted. A memorial marker stands at the blast site; the steppe around the epicenter still shows altered vegetation. Commemorative events are held here every year on 14 September.

Location

Totsky Range lies 40 km north of the village of Totskoye in Orenburg Oblast, about 200 km west of the city of Orenburg along the road to Samara. The nearest large city is Buzuluk, 50 km away.
