PFM-1

Also known as
  • PFM-1 mine
  • butterfly mine
  • petal mine
  • Green Parrot
  • Lepestok

The PFM-1 is a Soviet scatterable anti-personnel blast mine with a plastic winged body and a small liquid-explosive charge, designed for remote delivery rather than hand emplacement. It is documented in Soviet-era helicopter-dispersed mine contamination in Afghanistan and in 2014 Russia-Ukraine War use by both rocket-delivered PFM-series mines around Izium and drone-dropped mines around Kherson.

Role in conflict
Helicopter-dispersed antipersonnel mine warfare

Human Rights Watch's Asia Watch report said PFM-1 butterfly mines were dropped in large numbers during the Soviet war in Afghanistan and that many remained active after the Soviet withdrawal because the more widely used PFM-1 lacked a self-destruct mechanism.

Human Rights Watch reported apparent Ukrainian rocket-delivered PFM-series mine use around Russian-occupied Izium in 2022 and separately documented Russian forces dropping PFM antipersonnel mines from quadcopter drones in and around Kherson in 2024-2025.

About 37 g of liquid high explosive, commonly reported as VS-6D or VS-60D
Fuze
Hydraulic pressure-operated fuze with arming delay
Activation pressure
Approximately 5-25 kg reported for PFM-1

9M27K3 payload
312 PFM-series antipersonnel mines per 220 mm mine-laying rocket
Variants

PFM-1 references usually cover the base mine and the PFM-1S self-destruct version; both retain the same general scatterable butterfly-mine form while differing in self-destruct behavior.

PFM-1SSelf-destruct version

ODIN and CAT-UXO describe the PFM-1S as the self-destruct version of the mine, while the HRW Afghanistan report distinguished the more widely used PFM-1 as lacking a built-in self-destruct mechanism.

Documented Delivery Systems

The PFM-1 is normally documented as a remotely delivered mine, with the evidence here pointing to rocket, helicopter, and improvised UAV delivery rather than hand emplacement.

ARES identifies the 9M27K3 Uragan rocket as carrying 312 PFM-series antipersonnel mines, and HRW tied PFM-series remnants around Izium to 9M27K3 rocket delivery.

Delivery And Hazard Profile

PFM-1 evidence is strongest when the mine is treated as a remotely scattered payload. The same small plastic body appears across helicopter, rocket, and drone delivery contexts, but the tactical pattern differs by carrier.

Timeline

PFM-1 Key Events

  1. Soviet intervention begins in Afghanistan

    The Soviet-Afghan War later produced extensive PFM-1 contamination, with HRW reporting that butterfly mines dropped during the war remained active after the Soviet withdrawal.

  2. PFM-series mines reported around Izium

    Human Rights Watch reported apparent Ukrainian 9M27K3 rocket delivery of PFM-series mines around Russian-occupied Izium, including PFM-1S remnants and civilian casualties.

  3. HRW documents drone-dropped PFM mines in Kherson

    Human Rights Watch documented Russian forces dropping PFM antipersonnel mines from quadcopter drones in and around Kherson during 2024-2025.
