Design
The GROM MANPADS is designed to be operated by one soldier. It consists of a single-stage projectile, a single-use tubular launcher, a starting mechanism, and an on-ground power supply. The whole GROM system including the launch unit and the missile has a total weight of 16.5 kg. GROM system features a dual-channel IR seeker and highly sophisticated FM-tracking logic target discrimination selection unit to defeat sophisticated (pyrotechnically, blinking, and modulated) IR decoys.

Missile
The missile is powered by a solid-fuel engine and is equipped with an infrared homing system. The missile of the GROM system can hit a flying target at a distance from 400 m to 5.5 km and from an altitude of 10 m minimum to 4 km maximum. The GROM missile uses a "duck" configuration with four drop-down stabilizers with a seeker at the front similar to the Soviet-made 9E410 cooled dual-band seeker. The infrared aiming sensor is cooled with liquid nitrogen. The GROM missile has a total weight of 10.5 kg including a 1.27 kg high-explosive warhead.

Features
The GROM system can be equipped with an "Identification Friend-or-Foe" IFF reconnaissance device and a thermal imaging sight. The IFF is an identification system designed for command and control. It enables military and national (civilian air traffic control) interrogation systems to identify aircraft, vehicles or forces as friendly and to determine their bearing and range from the interrogator. IFF may be used by both military and civilian aircraft.

Combat Use
The GROM is intended to engage low-flying targets on head-on and pursuit courses in clutter and IR jamming environments. When engaging slow or straight-receding targets, the operator tracks the target with the iron sights in the launch tube and applies a half-trigger. The shooter then pulls the trigger fully and immediately applies lead and superelevation.
