PZR Grom (Grom, meaning "thunder" in Polish) is a man-portable air-defense system produced in Poland and based on the Soviet man-portable infrared homing surface-to-air missile (SAM) 9K38 Igla. It consists of a 72 mm anti-aircraft missile set with a flight speed of 650 m/s, as well as a single-use launcher, re-usable gripstock and thermal battery coolant assembly electric unit. The full name of the system is Przeciwlotniczy Zestaw Rakietowy Grom (literally, anti-air rocket-propelled set).
It is designed to target low-flying helicopters and aeroplanes. As such, the Grom missile is used by other surface-to-air defence systems of Polish design, including ZSU-23-4MP Biała, ZUR-23-2 kg and Poprad self-propelled artillery system. It should not be confused with versions of the Zvezda Kh-23 air-to-surface missile built under licence in Yugoslavia/Serbia as the Grom-A and Grom-B.
