nuclearpowered

Kyiv, Ukraine – The collective West is scared of Moscow’s new, nuclear-powered cruise missile because it can reach anywhere on Earth, bypassing the most sophisticated air and missile defence systems, the Russian Ministry of Foreign Affairs has claimed.

“They’re afraid of what we’ll show to them next,” Foreign Ministry spokeswoman Maria Zakharova told the RIA Novosti news agency on Sunday.

Days earlier, she said Moscow was “forced” to develop and test the cruise missile, which is named the Burevestnik, meaning storm petrel – a type of seabird, in response to NATO’s hostility towards Russia.

“The development can be characterised as forced and takes place to maintain strategic balance,” she was quoted by the Itar-Tass news agency as saying. Russia “has to respond to NATO’s increasingly destabilising actions in the field of missile defence”.

With much pomp, Russian President Vladimir Putin on Tuesday handed state awards to Burevestnik’s developers.

Also awarded were the designers of Poseidon, an underwater nuclear-powered torpedo which Putin has also claimed has been successfully tested.

Russia says Poseidon can carry nuclear weapons that cause radioactive tsunamis, wiping out huge coastal areas. The “super torpedo” can move at the speed of 200km/h (120mph) and zigzag its way to avoid interception, it says.

“In terms of flight range, the Burevestnik … has surpassed all known missile systems in the world,” Putin said in his speech at the Kremlin. “Same as any other nuclear power, Russia is developing its nuclear potential, its strategic potential … What we are talking about now is the work announced a long time ago.”

But military and nuclear experts are sceptical about the efficiency and lethality of the new weapons.

It is not unusual for Russia to flaunt its arsenal as its onslaught in Ukraine continues. Analysts say rather than scaring its critics, Moscow’s announcements are merely a scare tactic to dissuade Western powers from supporting Kyiv.

“There’s nothing revolutionary about,” the Burevestnik, said Pavel Podvig, director of the Russian Nuclear Forces Project at the the United Nations Institute for Disarmament Research.

“It can fly long and far, and there’s some novelty about it, but there’s nothing to back [Putin’s claim] that it can absolutely change everything,” Podvig told Al Jazeera. “One can’t say that it is invincible and can triumph over everything.”

The Burevestnik’s test is part of Moscow’s media stratagem of intimidating the West when the real situation on the front lines in Ukraine is desperate, according to a former Russian diplomat.

The missile is “not a technical breakthrough but a product of propaganda and desperation”, Boris Bondarev, who quit his Russian Foreign Ministry job to protest against the 2022 full-scale invasion of Ukraine, wrote in an opinion piece published by the Moscow Times.

“It symbolises not strength but weakness – the Kremlin’s lack of any tools of political influence other than threats.”

Few details about ‘unique’ missile

The problem is that officials have so far unveiled very little about the Burevestnik, which NATO has dubbed the SSC-X-9 Skyfall – a missile that has a nuclear reactor allegedly capable of keeping it in the air indefinitely.

On October 26, when fatigues-clad Putin announced Burevestnik’s successful test, he was accompanied by his top general Valery Gerasimov.

“This is a unique item; no one else in the world has it,” said Putin, in televised remarks.

Gerasimov said the Burevestnik had flown 14,000km (8,700 miles) in 15 hours during a recent test. It can manoeuvre and loiter midair, and unleash its nuclear load with “guaranteed precision” and at “any distance”.

“There’s a lot of work ahead” before the missile is mass-produced, Putin concluded, adding the test’s “key objectives have been achieved”.

A Ukrainian military expert ridiculed the Kremlin’s claims.

“Much of the news report is fake, the (Burevestnik) missile is subsonic, it can be detected and destroyed by missile defence systems,” Lieutenant General Ihor Romanenko, former deputy head of Ukraine’s general staff of armed forces who specialised in air and missile defence, told Al Jazeera.

As for the Poseidon nuclear drone, it is too destructive – and can be used only as a second-strike, retaliatory weapon after the start of a nuclear war, experts warned. As with the Burevestnik, the lack of detailed information about Poseidon casts doubt upon the Kremlin’s claims.

Trump decries ‘inappropriate’ tests

The announcements followed Washington’s scrapping of United States President Donald Trump’s summit with Putin in Budapest, Hungary.

Trump has called the Burevestnik’s test “inappropriate” and ordered the Pentagon to resume the testing of nuclear weapons and missiles.

But ahead of next year’s midterm elections, he may seek to show how he forced the Kremlin to stop hostilities in Ukraine.

“Trump will have to play with pressure on Russia,” Romanenko said. “Hopefully, the circumstances will force Trump to act.”

What Putin has not mentioned is that only two of the Burevestnik’s dozen tests, starting in 2019, have been successful.

Its 2019 launch near the White Sea in northwestern Russia killed at least five nuclear experts after a radioactive explosion, Western experts said at the time. Russia’s state nuclear agency acknowledged the deaths, but officials and media reports do not provide video footage, detailed photos or other specifics of the Burevestnik and its testing route – making Putin’s latest claims hard to corroborate or disprove.

Western experts were able to identify the Burevestnik’s probable deployment site in September. Known as Vologda-20 or Chebsara, it is believed to be 475km (295 miles) north of Moscow and has nine launch pads under construction, the Reuters news agency reported last year.

The missile’s capabilities have divided military analysts.

“In operation, the Burevestnik would carry a nuclear warhead (or warheads), circle the globe at low altitude, avoid missile defences, and dodge terrain; and drop the warhead(s) at a difficult-to-predict location (or locations),” the Nuclear Threat Initiative, a US nonprofit security group said in a 2019 report after the missile’s first somewhat successful test.

A year later, the US Air Force’s National Air and Space Intelligence Center said, if brought into service, Burevestnik would give Moscow a “unique weapon with intercontinental-range capability”.

‘Burevestnik is a mystification’

Others doubt the missile’s functionality.

“Burevestnik is a mystification for the whole seven-and-a-half years since it was first announced,” Pavel Luzin, a visiting scholar at Tufts University in Massachusetts, told Al Jazeera.

“It’s impossible to create a reactor that is compact and powerful enough to ensure a cruise missile’s movement,” Luzin said. “This is a basic physics textbook.”

Moscow claims that Burevestnik utilises nuclear propulsion instead of turbojet or turbofan engines used in cruise or ballistic missiles.

But Luzin said the smallest nuclear reactors used to power satellites weighed 1 metric tonne, supplying several kilowatts of energy – roughly equal to what a regular household consumes – while emitting some 150kw of thermal energy.

The experimental nuclear reactors developed in the 1950s and the 60s for aircraft weighed many tonnes and were the size of a railway carriage, he said.

An average engine for a cruise missile weighs up to 80kg, generates 4kw for onboard electric and electronic devices, and about 1 megawatt of energy for propelling the missile, he said.

Other analysts think that Burevestnik’s nuclear engine can function, but do not consider the weapon groundbreaking.

Russia has said that it conducted a long-awaited test of its mysterious Burevestnik (also known to NATO as SSC-X-9 Skyfall) cruise missile last week, claiming that it flew for 8,700 miles. The missile, which is nuclear-powered, is said to have remained in the air for around 15 hours. For the time being, we don’t know if those statements are factually accurate, and details about how the missile actually works remain very scarce. However, the claimed test has led to boasts about the missile’s performance from Russian President Vladimir Putin, while his U.S. counterpart, Donald Trump, called upon Putin to end the war in Ukraine “instead of testing missiles.”

Russia’s Chief of the General Staff, Valery Gerasimov, told Putin yesterday that a successful test of the Burevestnik was carried out on October 21. Gerasimov said that the 15-hour flight “is not the [maximum] limit” for the missile. Regardless, if true, this would appear to be the first long-endurance test of the missile.

In response to Gerasimov’s remarks, Putin commented: “I remember vividly when we announced that we were developing such a weapon, even highly qualified specialists told me that, yes, it was a good and worthy goal, but unrealizable in the near future. This was the opinion of specialists, I repeat, highly qualified. And now the decisive tests have been completed.”

The Russian president was referring to the revelation of the Burevestnik’s existence back in 2018. It was one of six ‘super weapons’ that also included hypersonic weapons and a nuclear-powered, nuclear-armed torpedo.

People are asking what’s the purpose of Burevestnik and why develop a system that is very much useless as a weapon. The answer has always been right there, in the 1 March 2018 address. Russian president has always wanted to say these words. The rest doesn’t matter really. pic.twitter.com/0Q7JUGBqo3

Of all these weapons, the Burevestnik has long been among the most intriguing.

As TWZ described when it was first announced, the basic concept of a nuclear-powered cruise missile is by no means new.

After all, in the 1960s, the U.S. Air Force explored a similar idea with its Supersonic Low Altitude Missile, or SLAM. This weapon employed a nuclear-powered ramjet along with conventional rocket boosters to kickstart the system. Once at the appropriate speed, the engine would blow air over the reactor, which could have enough fuel to operate for weeks or months on end, and then force it out of an exhaust nozzle to produce thrust.

A missile of this kind has extreme endurance, not limited by conventional fuel onboard as all other air-breathing missiles are, can be wildly unpredictable and tough to defend against.

While we don’t know what kind of nuclear propulsion the Burevestnik uses, provided this kind of technology can be made reliable, the implications are significant.

Of the latest test, Gerasimov said: “The technical characteristics of the Burevestnik generally allow it to be used with guaranteed accuracy against highly protected targets at any distance.” He added that: “vertical and horizontal maneuvers were completed,” something that would allow the missile to “bypass anti-missile and air defense systems.”

As we have surmised before, an operational Burevestnik would likely cruise at high subsonic speed on a circuitous route at extremely low altitude, helping it to avoid surface-based early warning systems and missile defense interceptors.

Using a two-way datalink, it should be possible to adapt the Burevestnik’s course in flight to further confuse an opponent or actively counter any attempts to intercept the missile.

The American SLAM concept involved a payload of multiple nuclear warheads that could be dropped on different targets along the way, but again, the warhead of the Russian missile remains mysterious. Dmitry Medvedev, the deputy chairman of the Russian Security Council, claimed that the latest test involved a warhead. If true, it would almost certainly involve a mock warhead, without the nuclear material, which would serve to test fuzing and detonation, for example.

Congratulations to all Russia’s friends on the successful test of the unlimited-range Burevestnik (Storm petrel) cruise missile with a nuclear engine and warhead ⚡️😃

Nevertheless, a technically perfected Burevestnik remains a somewhat questionable goal given previous problems with the program. At the same time, there remains the very real issue of safety and environmental hazards. We will dive deeper into both these factors later.

Returning to last week’s test, Gerasimov didn’t say where it took place, but it’s widely assumed to have been in Novaya Zemlya, an archipelago in northern Russia, situated in the Arctic Ocean, and used for many previous weapons tests.

Notice to Airmen (NOTAM) orders issued for October 21 showed a large area around Novaya Zemlya closed off, corresponding to a Russian missile test or live-fire exercise.

Meanwhile, several Russian vessels that are known to be used in missile tests were noted in positions along the coast of the Arctic archipelago, both on the Barents Sea and Kara Sea sides. Probable support aircraft belonging to Rosatom, the Russian state nuclear corporation, and the Russian Aerospace Forces were also seen at Rogachevo airfield on Novaya Zemlya.

There have also been flights by a U.S. Air Force WC-135 Constant Phoenix “nuke sniffer” aircraft in the region, which some observers suggested could have been related to a Burevestnik. After a flight by this aircraft around the Barents Sea on August 5, the Air Force told TWZ that this was “to conduct routine background collection … to ensure signatory nations are adhering to established United Nations treaties.” The Air Force spokesperson added that the deployment of the WC-135 to the United Kingdom was planned and scheduled months in advance.

Background collection is something that could be conducted in anticipation of a Burevestnik test in the future. This data will be used to compare that from a collection mission following a test. At the same time, the wider region hosts other Russian nuclear assets, which would also be of interest for such flights, which are fairly regular in occurrence.

Finally, the test site at Pankovo, north of Rogachevo, on Yuzhny Island in the Novaya Zemlya archipelago, has seen considerable activity starting this summer. Pankovo hosts what is understood to be the main launch site for the Burevestnik, with two rail-type launchers under a retractable covering.

On 21 October 2025 Russia conducted “the key test” of the Burevestnik nuclear-powered cruise missile (also referred to as SSC-X-9 Skyfall). The test is reported to be successful. The missile travelled 14,000 km in a 15-hour flight (Image: Pan’kovo test site). Links follow 1/ pic.twitter.com/OVuCCjPiDO

Provided that last week’s test was conducted from Pankovo, making use of the area signaled by the NOTAM, then the missile must have flown in a racetrack or zigzag pattern around the Arctic archipelago. Less likely would be a longer route flown across the north of Russia.

Whatever the case, Norway, the closest NATO country to the test area, said it hadn’t detected any spikes in radiation at any of its monitoring posts.

“We have not measured anything abnormal at our measuring stations in Norway,” a spokesperson for the Norwegian Radiation and Nuclear Safety Authority (DSA) told the Barents Observer. However, there is still time for such a reading to be made.

“If there has been a radioactive release in connection with Russia’s testing of the cruise missile, it will take a long time to travel to Norway, and it will take time before it can be registered at our measuring stations,” the DSA spokesperson added.

Previous tests of the Burevestnik have not been without incident.

When he announced the missile in 2018, Putin suggested that tests of the propulsion system had occurred the previous year, but there was no indication of whether this had been in flight or on the ground and under what conditions.

Soon after Putin’s 2018 announcement, the Norwegian-based environmental group Bellona suggested that a radiation spike in the Arctic that same winter was caused by the missile’s open-air-cooled reactor core.

Later in 2018, a U.S. intelligence report described the loss at sea of a Russian nuclear-powered missile during a 2017 test. The report added that Russia was expected to embark on a search and recovery mission to try to lift the missile’s wreckage from the seabed.

The Russian Ministry of Defense released the video below in 2018, saying that it showed an earlier Burevestnik test launch, as well as examples of the missiles themselves.

More dramatically, in 2019, an explosion occurred aboard a barge in the White Sea, outside Nenoksa, killing five Rosatom scientists. It also led to a radiation spike in the Russian city of Severodvinsk, as you can read more about here. The explosion has been blamed on a reactor from a Burevestnik recovered from the sea, likely the one that was lost in 2017.

While the details of these accidents remain murky, they point to a significant problem in using nuclear propulsion for a missile or any other vehicle flying in the atmosphere.

It should be recalled that, in the case of SLAM, the nuclear ramjet had no shielding to contain dangerous radiation, a requirement driven by the need for the powerplant to be small enough to fit inside the missile. The SLAM’s exhaust plume also contained unspent fissile material that would have contaminated any area, enemy-controlled or not, that it passed over on its way to the target.

While the Burevestnik has already been likened to a ‘tiny flying Chernobyl’ by some observers, it’s important to remember that we still don’t know how it functions.

Nevertheless, provided it does indeed use nuclear propulsion, as claimed, there exists the risk of accidents.

“The testing [of the Burevestnik] carries a risk of accidents and local radioactive emissions,” Norway’s Intelligence Service (NIS) stated in a threat assessment report published last year.

This is especially the case during an unarmed test, when the missile necessarily has to come down to the surface, impacting either land or water. Here, especially, there remain a lot of questions about how the missile is tested.

It’s possible that the missile came down in waters around Novaya Zemlya, in either the Barents Sea or the Kara Sea. According to the Barents Observer and other sources, there are several ships in this area, on both sides of the Matochkin Strait, which might be involved in a recovery operation.

These ships include Rosatom’s special-purpose vessel Rossita, on the eastern coast of the Kola Peninsula. This vessel was noted making port calls in Novaya Zemlya after previous presumed Burevestnik tests. The Rossita is equipped to transport spent nuclear fuel and other hazardous radioactive material.

Perhaps, if Norway subsequently detects a radioactive spike in this area, we might learn more about where the missile ended its flight.

In the meantime, Putin took the opportunity to push claims about the missile’s game-changing nature.

“We need to determine the possible uses and begin preparing the infrastructure for deploying this weapon in our armed forces,” Putin said yesterday. This is especially relevant considering that the New START treaty with the United States, which puts a limit on strategic nuclear warheads and launchers, expires next year. Gerasimov’s announcement of the long-distance test also came one day before Russia began its annual Grom strategic nuclear maneuvers.

When asked for his reaction to the claims of the Burevestnik test, President Donald Trump stated that the U.S. Navy has a nuclear submarine “right off their shores,” meaning that there is no immediate requirement for a missile with the kind of range that the Russian cruise missile should possess.

At the same time, Trump noted that Russia is “not playing games with us. We’re not playing games with them either.” As for Putin’s comments on the missile test, Trump said: “I don’t think it’s an appropriate thing for Putin to be saying,” reminding the Russian leader that the priority was to bring an end to the war in Ukraine.

Trump responded to Putin’s threats and the recent Burevestnik missile test by reminding that the US has a nuclear submarine “right off their coast.”

Still, the prospect of the Burevestnik entering service is a concerning one for adversaries of Russia. The missile can be launched preemptively and approach its target from any vector long after launch. For example, it could be launched from the Arctic, stay aloft for many hours, and then attack the United States from the south. Once launched, its flight path is entirely unpredictable, and it could exploit holes in defenses and weaker spots in early warning capabilities. It provides another reason why space-based tracking layers, including those that can spot low-flying aircraft, are currently very much on trend.

It is also worth noting that the latest Burevestnik test comes at a time when the U.S. Golden Dome initiative is taking shape, and the Russian missile reinforces the case for such a system. At the same time, it also underlines the reason why Russia wants weapons like this, so that it can better bypass existing strategic air defense systems.

The latest developments leave no doubt that the Burevestnik is a prestige program for Russia, even if many questions still surround it, and the nature of the latest test.
