Iskander-M
BLUF
The Iskander-M (NATO: SS-26 Stone) is Russia’s primary operational-tactical short-range ballistic missile (SRBM) system, with a range of ~500 km and sub-meter CEP accuracy. In the Ukraine War, it has been Russia’s principal precision-strike weapon for attacking fixed high-value targets — command centers, air defense radars, logistics nodes, fuel depots, and civilian infrastructure. Unlike the Kalibr (sea-launched), Iskander-M is road-mobile and ground-launched, enabling rapid deployment from any accessible terrain within range of target sets. Its quasi-ballistic flight profile (maneuvering mid-course and terminally) complicates intercept by Patriot PAC-3 and other TMD systems. The Iskander-M also carries a nuclear variant, making it Russia’s primary dual-capable (conventional/nuclear) theater weapon.
Technical Specifications
| Parameter | Value |
|---|---|
| Type | Short-range ballistic missile (SRBM), quasi-ballistic |

| CEP | <2–5 m (active radar terminal seeker) |
| Guidance | INS + GLONASS + active radar terminal seeker + optical scene-matching |
| Flight profile | Quasi-ballistic: low-altitude cruise phase + steep terminal dive; maneuvering warhead (MARV) in advanced variants |
| Launch platform | Road-mobile 8×8 TEL (Transporter-Erector-Launcher) |
| Reload time | ~16 minutes per TEL |
| Missiles per TEL | 2 |
| Developer | Iskander designer KBM (Kolomna Machine Design Bureau) |
Operational Use — Ukraine War (2022–present)
Iskander-M has been used throughout the Ukraine War for:
- Decapitation strikes: Targeting Ukrainian command posts, HQ buildings, and military leadership nodes
- Air defense suppression: Strikes on Ukrainian S-300/Buk-M1 radar and launcher vehicles
- Infrastructure attrition: Combined with Kalibr and Shahed-136 in coordinated saturation attacks on power grid, energy, and logistics
- HIMARS counter-battery: Russia attempted to locate and destroy Ukrainian HIMARS launchers with Iskander-M strikes, with mixed results
The quasi-ballistic profile with terminal maneuvering has made Iskander-M intercept by Patriot PAC-3 challenging but not impossible — Ukrainian Patriot batteries have achieved documented Iskander intercepts at low exchange ratios.
Inventory concern: Russia has expended significant Iskander-M inventory in Ukraine. Production rates at Votkinsk Machine Building Plant have been accelerated under wartime conditions; exact stockpile status remains a NATO intelligence gap.
Key Connections
- Ukraine War — primary operational deployment
- Kalibr — complementary long-range strike; Iskander fills shorter-range precision role
- Shahed-136 — combined-arms saturation partner
- HIMARS — US-supplied Ukrainian counter-battery rival
- Patriot PAC-3 — primary Western interceptor tasked against Iskander terminal phase
- Russian Federation — operator
- Hybrid Warfare — Iskander’s dual-capable (conventional/nuclear) status is a key element of Russian nuclear signaling
