The return of nuclear jet propulsion – unlimited range against shields, at the price of radiation
The West immediately dubbed it the “Flying Chernobyl”; Russia calls it 9M730 Burevestnik – “storm petrel” (or “storm bird”). This project did not begin with the war in Ukraine but with Moscow’s analysis of what it considers the fundamental problem of nuclear balance: the expansion of American missile defense systems that, even if only partially effective, erode the logic of mutual deterrence. As early as 2018, Vladimir Putin included it in the package of “responses” to shields and interceptors, alongside Avangard, Kinzhal, Zircon, and Poseidon. Since then, Burevestnik has become synonymous with a weapon that defies engineering limits – and the nerves of those who think about radiological risk.
Technically, Burevestnik is a nuclear-powered cruise missile. After initial acceleration by a small rocket booster, air enters the missile body where a mini-reactor heats it and expels it backward – a nuclear ramjet. The idea is reminiscent of the American Project Pluto from the 1960s, which was abandoned precisely because it was “dirty”: such an engine can release radioactive isotopes during flight. Russian engineers claim that modern materials and reactor control have reduced this risk, but the very concept carries a special kind of danger that conventional turbofan engines of classic cruise missiles do not have.
What gives Burevestnik its strategic meaning is range. In practice – as long as the reactor lasts. In recent months, the Moscow leadership has emphasized that a multi-hour flight of more than 14,000 kilometers without interruption has been completed, and that “this is not the upper limit.” Such endurance opens up a flight profile that defenses find hard to predict: the missile can loiter, change course, arrive from an unexpected direction, and even wait for the right moment to strike. The price of this endurance is speed: estimates suggest subsonic flight (roughly like the Tomahawk), but at extremely low altitudes of 50–100 meters, terrain-hugging flight, and a maneuvering route that turns the radar horizon into an ally.
Guidance, judging by the fragments that have leaked, is a combination of inertial navigation, satellite correction (GLONASS), and terrain mapping – the old Soviet school brought into the digital age. In size, Burevestnik is among the larger cruise missiles (around 12 m), with aerodynamics suggesting an attempt to reduce radar cross-section – it is not “stealth,” but it is designed to be detected late. The key point, however, is that – unlike hypersonic weapons – it relies on stealthy approach rather than speed.
In the Russian arsenal, Burevestnik occupies a unique place. Avangard is its opposite: a hypersonic glide vehicle atop an ICBM, speeds of 20+ Mach, designed to punch through defenses with brute force and high-altitude maneuvering. Kinzhal is an air-launched quasi-ballistic missile for fast, regional strikes – already used conventionally in Ukraine. Zircon is a sea-based hypersonic missile for ships and land targets, with a range on the order of a thousand kilometers. All three prioritize speed over endurance. Burevestnik takes the other path: slow, low-flying, practically unrestricted in route and range. If the first wave of ICBMs and SLBMs hits the main targets, Burevestnik is intended as the “second echelon” that hunts surviving command nodes, radars, and logistics.

Compared to systems in other countries, the closest conceptual relative is something that never really came to life – the aforementioned Pluto. The Americans did have the excellent stealth nuclear AGM-129 and the older AGM-86B: cruise missiles with nuclear warheads, but with conventional engines and ranges of a few thousand kilometers. Tomahawk and its relatives have shown how a subsonic, low-flying missile can penetrate saturated air defenses – but all such platforms depend on a launch point relatively close to the target. The Chinese are going a different route: the CJ-100 (DF-100) chases speed (allegedly up to hypersonic values) and strategic reach of several thousand kilometers, without nuclear propulsion. Only Russia has decided to pay the complexity and risk of a nuclear ramjet in exchange for unprecedented range.
Could Burevestnik appear over Ukraine? Almost certainly not. It is a nuclear weapon with nuclear propulsion – its very use would imply crossing a red line that Moscow, despite tough rhetoric, carefully avoids. For regional use, Russia has simpler, cleaner, and more reliable options (Iskander, Kalibr, Kh-101, and even Kinzhal). Moreover, according to Russian claims, the project has only recently reached full flight profiles; operational deployment and procedural fine-tuning are still ongoing. The real arena for Burevestnik is a hypothetical wider war with NATO, where it would exploit gaps in coverage and arrival “from nowhere” as a second-strike asset to render fixed missile defense installations meaningless.
What do experts say? Russian military writers see Burevestnik as a restoration of parity: an evil quest for an “impenetrable shield” is countered by a weapon that arrives below the horizon and from a direction no one prepared for. In a crisis, the mere possibility of multi-hour loitering and retargeting creates pressure on the opponent by itself. In the West, skepticism dominates: the argument is that Russia already has sufficient ICBM/SLBM capacity to saturate defenses, while Burevestnik introduces enormous operational and ecological uncertainty. People also recall the black series of early tests, including the 2019 reactor explosion near Nyonoksa that killed scientists and caused a brief spike in radiation. Critics conclude: the strategic added value is small, the risks are huge.
Yet not everything is about ideology – it’s about physics and geometry. NATO’s missile-defense backbones are oriented toward high, fast ballistic threats. Few systems are adapted to a quiet, low-flying object arriving from the South Atlantic or over the Arctic after fifteen hours of wandering. Combat air patrols and AWACS can catch a cruise missile – but they must first see it and have time to intercept. Burevestnik offers “asymmetry of time and direction” here. The flip side is that longer flight means more opportunities to detect and shoot it down, and subsonic remains subsonic: once detected, it is not unattainable.
The advantages and disadvantages of such a weapon are therefore sharp. Pros: practically unlimited range, route and timing flexibility, psychological and operational pressure on enemy defense plans, not covered by existing strategic arms treaty quotas. Cons: reliability (a mini-reactor that must run stably for hours is no trivial matter), radiological risk in flight, in case of crash or during maintenance, slowness compared to hypersonics, logistical and personnel complexity (specialized infrastructure, security protocols, fuel and waste disposal).
Can it be produced in large numbers? A limited series is more likely. Each Burevestnik is not “just another airframe with an engine” but a reactor, fuel core, shielding, instrumentation – all miniaturized and under strict mass constraints. That requires a nuclear industry with excess capacity and a discipline that only a few countries possess. Russia has Rosatom and experience with nuclear icebreakers and submarines, but serial production will probably be measured in tens per year, not hundreds. And that makes sense: strategic weapons of this type are not needed in thousands; their task is niche – to create uncertainty, and thus deterrence.
If we look beyond the exhibit, the question remains: does Burevestnik change the strategic equation? Probably less than the mythology around “unprecedented weapons” suggests. Nuclear balance is in any case maintained by the ability to guarantee retaliation and the redundancy of systems that already exist. Burevestnik further complicates the life of planners and signals Russia’s technological and industrial persistence – that alone is not insignificant. But it comes with a price: a new dimension of ecological danger and operational risk, and a “gray zone” between demonstration and use that in a crisis can trigger wrong decisions.
In other words: “Flying Chernobyl” is a label that says more about Western nerves than about the system’s actual purpose. Burevestnik is not a weapon for Kharkiv or Odesa, but for the darkest scenario of global confrontation. If it ever becomes fully operational, it will change the perception of vulnerability of defensive backbones – but it is unlikely to change the fundamental logic of nuclear deterrence. And that may be the soberest conclusion: behind the dramatic nickname lies a cold, almost bureaucratic goal – to keep uncertainty in the opponent’s mind long enough that war never happens.
