The RK-2S is a Ukrainian 130 mm tandem-charge guided missile from SE State Kyiv Design Bureau Luch. Official Luch materials list it in transport and launching containers for SKIF/Stugna-P, AMULET, BAR'ER, and SARMAT-related launch contexts, while Oryx and secondary reporting connect RK-2S missiles to Ukrainian anti-armor use and supply during the 2014 Russia-Ukraine War.
Oryx listed a small number of RK-2S Baryer anti-tank guided missiles purchased from CMI Group in Belgium for Ukraine in November 2022, while 19FortyFive described RK-2S as the standard Stugna-P missile used against Russian armored vehicles during the full-scale invasion.
Role detailsLuch's RK-2 missile family splits the SKIF/AMULET transport-launch-container set by caliber and warhead: 130 mm RK-2S/RK-2OF missiles and 152 mm RK-2M-K/RK-2M-OF missiles.

RK-2S is the 130 mm tandem-charge branch of the RK-2 missile set used with Luch's SKIF/Stugna-P and AMULET launcher families. The same official materials place it beside a 130 mm high-explosive fragmentation round and two 152 mm RK-2M missiles, so the designation mainly marks caliber and warhead role inside a shared launch-container ecosystem.
| Missile | Caliber | Warhead | Documented context |
|---|---|---|---|
| RK-2S | 130 mm | Tandem hollow-charge | Listed by Luch for SKIF/Stugna-P and AMULET as the smaller anti-armor missile in transport and launching containers. |
| 130 mm | High-explosive fragmentation with EFP | Named beside RK-2S as the 130 mm fragmentation option for the same launcher family. |
| 152 mm | Tandem hollow-charge | Listed as the larger-caliber tandem-charge counterpart in the RK-2M branch. |
| 152 mm | High-explosive fragmentation | Listed as the larger high-explosive fragmentation option in the same missile set. |
Luch's SKIF product page and brochure list RK-2S as the 130 mm tandem hollow-charge missile option in the system's transport and launching containers.
