Russia Declares 9M730 Burevestnik Nuclear Cruise Missile Test Marks Global-Reach Capability

Russia has conducted a long-range test of its 9M730 Burevestnik nuclear-powered cruise missile, reportedly flying 14,000 km over 15 hours. The trial underscores Moscow’s push to field a system designed to evade Western air and missile defenses, deepening strategic tensions with NATO.
On Sunday, 26 October 2025, the Kremlin said Russia has carried out a long-duration flight test of the 9M730 Burevestnik, a nuclear-powered, nuclear-capable intercontinental cruise missile, an announcement delivered by President Vladimir Putin during a televised briefing and reiterated by his top brass. Citing the commander’s report, the flight covered roughly 14,000 km over about 15 hours on 21 October, a profile intended to underscore claims of near-unlimited endurance and highly variable routing at very low altitude. This development is relevant because it introduces a propulsion concept designed to outlast and outmaneuver layered air and missile defenses, complicating early warning and air-policing doctrines across the Euro-Atlantic area. The news, as announced by President Putin live and reported by Reuters, signals Moscow’s intent to move from demonstration toward deployment, with the Kremlin framing the system as able to pierce “any missile defences.”

Burevestnik, known in NATO reporting as SSC-X-9 “Skyfall”, is a ground-launched, subsonic cruise missile that substitutes a nuclear heat source for conventional fuel, driving what analysts assess to be a turbojet cycle. In concept, that powerplant enables months of endurance and effectively global range, supporting low-altitude, terrain-following profiles that can hug the surface to reduce radar exposure. The flight parameters disclosed this week, 14,000 km in 15 hours, are consistent with that design logic. The program dates back at least to its public unveiling among six “new strategic systems” in 2018; its earlier test campaign drew allied concern not only over flight stability but also environmental risk, highlighted by a 2019 accident linked to related testing that killed Russian specialists and briefly raised local radiation levels. Moscow’s present messaging stresses readiness and deterrent value, while Western agencies continue to debate operational reliability and basing concepts for a system designed to loiter and approach from unexpected azimuths.
From a technical standpoint, Russian descriptions point to a nuclear turbojet, terrain-following navigation, and an extremely low flight envelope typical of cruise missiles, with claimed profiles measured in tens of meters above ground or sea level to complicate radar detection. Even without published specifications on seeker architecture, the combination of endurance and low altitude suggests a platform optimized for circuitous ingress, multi-leg routes, and late-stage evasive maneuvers to saturate or bypass fixed air- and missile-defense geometries. By pairing nuclear power with a nuclear or conventional payload option, the design aims to maintain persistent strike presence far outside traditional patrol radii and to exploit gaps in ballistic-missile defense systems that are not primarily configured for low-flying cruise threats.
Operationally and historically, Burevestnik sits at the intersection of earlier nuclear-propulsion experiments and modern precision-strike doctrine. It echoes the United States’ Cold-War Project Pluto lineage, abandoned for safety and strategic rationale, while adopting contemporary guidance and low-observable shaping associated with current cruise inventories. Russian authorities now frame the 21 October firing as proof-of-concept for endurance and routing flexibility, after a years-long development path marked by intermittent testing and safety controversy. The Kremlin’s statement that the system is readying for deployment, coupled with broader strategic-forces drills, positions Burevestnik as part of a portfolio intended to signal that Russia retains multiple, diverse long-range options beyond classic ICBMs and SLBMs.
A capability-based comparison helps situate this claim. NATO’s most widely fielded land-attack cruise missiles, such as the U.S. Navy’s Tomahawk Block IV/V and the U.S. Air Force’s AGM-158B JASSM-ER, are conventionally powered and conventionally armed in routine service, with operational ranges on the order of ~1,000 miles (Tomahawk) and greater than 500 nautical miles (JASSM-ER). The Franco-British Storm Shadow/SCALP-EG, also conventionally armed, publicly advertises ranges in excess of 250 km and has seen extensive combat use. Nuclear-armed cruise capability on the NATO side is today concentrated in France’s ASMP-A, a supersonic air-launched system assessed at roughly ~500–600 km class, designed for “pre-strategic” deterrence. Against that backdrop, Burevestnik’s asserted “virtually unlimited” reach and months-long endurance are outliers, trading demonstrable combat pedigree for a propulsion concept that, if fielded, could approach targets from nontraditional directions after prolonged loiter, albeit at the cost of safety, logistics, and signature management questions unique to nuclear air-breathing engines.
The strategic implications are immediate for air defense planners and arms-control advocates alike. At the operational level, a persistent, very-low-altitude cruise platform pressures radar fences, airborne early-warning orbits, and fighter-interceptor readiness by expanding both the time window and the azimuth set for potential ingress; it also increases demands on distributed sensors, passive detection networks, and counter-UAS/cruise-missile layers rather than classic ballistic-missile shields. Geopolitically, the test lands in a fragile arms-control environment: the INF Treaty collapsed in 2019, and New START, already constrained, expires in February 2026 absent replacement. A nuclear-powered intercontinental cruise missile falls outside prior treaty architectures and, if deployed, would widen the deterrence signaling menu while eroding the residual predictability provided by legacy agreements. That prospect will likely prompt NATO states to accelerate integrated air- and missile-defense upgrades, long-range fires deployments, and sensor-fusion initiatives, trends already visible in U.S. and European plans, and could catalyze renewed debates over confidence-building measures specific to novel propulsion and very-long-endurance systems.
President Putin’s formulation that Burevestnik has “no analogues” and can overcome “any missile defence” is a political statement; technically, the test profile Russia disclosed, 14,000 km over 15 hours, demonstrates endurance rather than terminal survivability against dense, modernized integrated air-defense systems with layered sensors and shooters. Western assessments will therefore focus on the missile’s actual navigation robustness, emissions control, guidance accuracy after prolonged flight, and the basing, handling, and safety concept for a nuclear heat source aboard an air-breathing engine. Those elements, more than range alone, will determine whether the system is a niche deterrent signal or a repeatable operational capability.
Russia’s announcement, delivered publicly by the President and amplified by the General Staff, marks a significant inflection point in long-range strike signaling: a move from exotic prototype toward a putative fielded option expressly intended to stress current defense architectures. As announced by President Putin live and reported by Reuters, the flight-time and distance claims are designed to communicate staying power and unpredictability; the strategic message is that Moscow seeks additional, non-ballistic paths for assured retaliation or coercive reach. Whether the Burevestnik becomes an integrated order-of-battle asset or remains a specialized deterrent instrument, the test underscores a broader reality for NATO capitals: the cruise-missile challenge is diversifying in propulsion, routing, and persistence faster than legacy air-defense and arms-control frameworks were built to handle.
