The RK-3 Corsar is a Ukrainian 107 mm portable anti-tank guided missile system from State Kyiv Design Bureau Luch, built for short-range infantry anti-armor and precision fires out to 2.5 km. Its laser-beam guidance, thermal-imager-compatible launcher, and RK-3K tandem HEAT or RK-3OF high-explosive fragmentation missiles give Ukrainian small units a lighter domestic ATGM alongside the heavier Skif/Stugna-P family, with documented use from the Donbas front through the full-scale 2014 Russia-Ukraine War.
Ukrainian forces operated Corsar on the Donbas front by 2019, including a geolocated Svitlodarsk-bulge launch toward Russian-backed separatist positions near Lozove; during the 2022 full-scale invasion, National Guard OMEGA and other Ukrainian teams used it against Russian armored vehicles, including an IFV near Velyka Komyshuvakha and a vehicle-column engagement at about 2.5 km.
Role detailsLuch describes Corsar as a light launcher built around transport-launch-container missiles, a mount that can be omitted for some firing positions, and day/night firing with a thermal imager. The result is a short-range ATGM that trades Stugna-P range for a smaller infantry load.
| Element | Documented detail | Why it matters |
|---|---|---|
| Launcher | 12 kg launcher listed by Luch | Portable enough for small anti-armor teams. |
| Mount | 8.3 kg mount, with firing also possible without the mount | Supports prepared positions, trench-parapet firing, and lighter short moves. |
| Missile container | 15.5 kg missile in a 1,180 mm transport-launch container | Keeps the RK-3K and RK-3OF missile options in the same handling format. |
| Sighting | Manufacturer page lists day and night firing with thermal-imager use | Extends the system beyond daylight anti-armor work when suitable sights are fitted. |
Luch presents Corsar as a launcher and transport-launch-container system with two 107 mm missile/warhead options, giving the same light launcher either anti-armor or fragmentation roles.
| Variant | Configuration | Designation notes |
|---|---|---|
| RK-3K | Tandem hollow-charge HEAT missile | The anti-armor missile option is listed for targets protected by explosive reactive armor and is rated by Luch at at least 550 mm penetration behind ERA.

| RK-3OF | High-explosive fragmentation missile | The fragmentation missile option is listed for light armor, field positions, and other non-tank targets; Luch lists an EFP penetration figure of at least 50 mm.

Corsar sits below the heavier Skif/Stugna-P in Luch's Ukrainian ATGM family. DFRLab described RK-3 Korsar and Stugna-P as the two Ukrainian-made ATGMs appearing in 2019 Donbas frontline videos, while Defense Express later reported both systems in full-scale-war ambush and shoot-and-scoot use. The practical split is range and system mass: Corsar is the lighter 107 mm, 2.5 km weapon; Skif/Stugna-P carries larger 130 mm and 152 mm missile options for longer-range engagements.
Ukrainian Military Pages reported that the Corsar system had been accepted into Armed Forces of Ukraine service and that initial missiles were already in the troops.
