The containment of the Chernobyl disaster relied heavily on the mobilization of Soviet rotary-wing assets. The operation utilized Mi-6, Mi-8, and heavy-lift Mi-26 helicopters to execute precision drops over the destroyed Unit 4 reactor.
The engineering objective was to halt the graphite fire and suppress the release of fission products. Crews dropped over 5,000 tonnes of boron, lead, sand, clay, and dolomite into the exposed core.
The operational environment was exceptionally severe. At 200 meters above the reactor, extreme thermal heat altered helicopter aerodynamics, making target acquisition difficult. Dose rates in the updraft exceeded 1,000 roentgens per hour. Initial operations required hovering directly over the shaft, but due to lethal exposure rates, flight patterns were altered to drop payloads during forward flight or via a continuous "carousel" formation.
These helicopters were also repurposed for large-scale decontamination, spraying polymer adhesives over the facility to lock down radioactive particulates.
The structural surfaces and engines of these aircraft became heavily irradiated. They were subsequently decommissioned and deposited at the Rassokha vehicle graveyard.
The images below were captured during my documentation of the zone in 2011. Due to ongoing remediation and unauthorized metal salvaging, these airframes were entirely removed and destroyed by 2013. The physical history of the airborne response no longer exists.
