[5] The gun is intended for engaging materiel, low flying aircraft, light vehicles, and dismounted infantry.
The AG-17 weapon system uses VOG-17M fragmentation rounds with a non-delay point fuse detonating on impact, designed to engage soft targets in cover.
The Stalker mounts two retractable launchers that each carry two ready-to-fire missiles, with an additional six reloads stored in the hull.
[7] The missile has replaced the older 3M11 Falanga (AT-2 Swatter) on the Mi-24 Hind attack helicopter, yet the SACLOS system with IR missile tracking, and radio guidance, similar to the uprated version of the Swatter, the AT-2c, operates the same as the AT-4 Spigot and AT-5 Spandrel which unlike the AT-6 Spiral are wire-guided.
[14][15] The system is designed to engage fixed-wing and rotary-wing aircraft, cruise missiles and UAVs flying at speeds of 360–400 m/s in head-on engagement (approaching target) and up to 320 m/s in tail chase (receding target) within their optical visibility and in the night-time conditions in background clutter and thermal countermeasures environment.
