The 9M729 is a Russian NPO Novator ground-launched cruise missile known to NATO as the SSC-8. CSIS lists it as a 2,500 km-range system, NATO identifies it as mobile and nuclear-capable, and Ukrainian officials have linked Russian 9M729 firings to the Russia-Ukraine War 2014-present.
Ukrainian officials and Reuters-linked debris reviews identify Russian 9M729 launches against Ukraine, including two recorded 2022 launches, repeated firings from August 2025, and additional reported February 2026 attacks.
The 9M729 is both a munition and an arms-control reference point: it is a road-mobile Russian ground-launched cruise missile tied to the Iskander-K family, but its assessed range drove the INF Treaty dispute that ended in 2019.
| Designation | Context | Why it matters |
|---|---|---|
| 9M729 | Russian missile designation | Identifies the munition reported in Ukraine. |
| SSC-8 / SSC-X-8 | NATO reporting name and earlier experimental form | Connects treaty, NATO, and U.S. reporting to the same missile. |
| 9M728 / R-500 | Related Iskander-K cruise missile | Serves as the shorter-range family comparison point. |
The 9M729 sits in the Novator ground-launched cruise missile family associated with Iskander-K launchers; NATO reporting names distinguish it from the shorter-range 9M728.
| Variant | Configuration | Designation notes |
|---|---|---|
| 9M728 / R-500 | Earlier Iskander-K cruise missile | Russian and Western reporting treat the 9M728 as the related shorter-range ground-launched cruise missile family member. Sources: 9M729 (SSC-8) |
| SSC-8 / SSC-X-8 | NATO reporting name | CSIS records SSC-X-8 as the experimental designation before the missile was treated as an operational SSC-8 system. Sources: 9M729 (SSC-8) |
The 9M729 is a ground-launched cruise missile associated with Russia's road-mobile Iskander-K launch architecture.
| Launcher | Launcher type | Launch evidence |
|---|---|---|
 | Road-mobile missile launcher family | CSIS and specialist reporting connect the 9M729 to Iskander-K or an Iskander-like mobile TEL, with later Russian presentation material showing launch canisters and an associated launcher.

The United States publicly reported a Russian ground-launched cruise missile treaty violation before the 9M729 designation was widely identified.
U.S. officials reported that Russia had deployed SSC-8 missile battalions, moving the system from testing into operational concern.
Russia publicly displayed 9M729 launch canisters and argued the missile remained INF-compliant despite NATO and U.S. objections.
The United States withdrew from the INF Treaty with NATO support after continued disagreement over Russia's SSC-8/9M729 compliance.
Ukrainian officials told Reuters that Russia had fired 9M729 missiles against Ukraine, including repeated launches from August 2025.
Reuters-linked reporting cited at least four more Russian 9M729 firings at Ukraine and debris with 9M729 markings in western regions.
