Russia has built hardened shelters to protect its vulnerable aircraft at several bases following a string of long-range Ukrainian drone strikes, a new Western intelligence assessment suggests.
Britain's defense ministry this week published satellite imagery from early June, collected by the US company Planet Labs, that shows newly constructed shelters at three Russian air bases behind the front lines.
The shelters, which consist of dome-shaped rooftops and thick blast doors, were photographed at Russia's Millerovo, Kursk Vostochny, and Hvardiiske air bases. Some structures were seen covered with earth for added protection that could help shield against shrapnel or other debris.

The UK said in a Tuesday intelligence update that Russia had launched efforts to protect vulnerable aircraft at several bases "in response to numerous successful" Ukrainian drone attacks. Millerovo, just a few miles across the border, for instance, was targeted just last week.
"The construction of these hardened aircraft shelters provides a layer of protection to aircraft deployed to Russian airbases against future" Ukrainian drone attacks, the UK explained.
Hardened shelters are one of several tactics that Russia has turned to in an effort to protect its fighter jets from the Ukrainian attacks. Moscow has also painted decoy warplanes on the tarmac at its air bases and even covered its bomber aircraft with tires in an attempt to confuse Kyiv's targeting and mislead the drones. It's unclear, however, how effective these protective measures have been.

Ukraine's long-range drone attacks have been a bright spot for Kyiv during the three-and-a-half-year-long war, which has transitioned from a maneuver conflict to one of attrition, featuring largely static front lines and standoff strikes from distance.
The US long prevented Ukraine from using Western-provided missiles to strike across the border and inside Russian territory. That arsenal was also quite limited. As a workaround to these restrictions, Kyiv invested heavily in domestic drone production.
Over the past year, Ukraine has repeatedly used homemade long-range drones to strike a range of high-value military and energy targets inside Russia, including oil terminals, ammunition depots, weapons-making factories, and air bases.
Russian air bases have been a particular focus for the Ukrainian military, as Moscow uses these sites to stage deadly attacks against troops and civilians, relying on missiles and guided bombs.
On Tuesday, conflict analysts at the Institute for the Study of War, a US-based think tank, said in a battlefield assessment that Ukrainian forces "appear to be intensifying a long-range strike campaign against Russian military industrial facilities and transport networks."

Ukraine's special operators used to focus their training on surviving intense Russian artillery fire. Now, their attention has shifted to drones β the main battlefield killer.
"Things have changed drastically," an American instructor with the 4th Ranger Regiment of Ukraine's Special Operations Forces told Business Insider. He could only be identified by his call sign Scooter for security reasons.
"One of the main differences we see today is the prevalence of drones," he said. "In 2022, it was primarily artillery fire. There was a lot more of it." The Ukrainian Rangers are now learning better concealment tactics and how to shoot down drones with their service weapons as a last resort.
Artillery, long described as the "king of battle," has played a central role in Russia's full-scale invasion of Ukraine, especially during the early years of the conflict, with both sides using the towed cannons and multiple launch rocket systems to attack the enemy.
The scale of the artillery duels could be seen in satellite imagery of the battlefield, where hundreds of craters peppered huge swaths of land and reduced buildings to rubble.
However, amid strained ammunition stockpiles and as the war transitioned from a maneuver-oriented conflict to one of attrition, with relatively static front lines, drones have emerged as the dominant battlefield threat, with some recent estimates suggesting that they are causing around 70% of Russian and Ukrainian casualties.

Scooter attributed the rise of drones to what has been called "shell hunger," explaining that Russia exhausted its stocks of artillery ammunition and began to rely on small quadcopter drones β known as first-person view, or FPV, drones β to fill the gaps. Ukraine also experienced a shortage of artillery rounds, turning to drones as an alternative.
"In 2022, we were trained to utilize terrain and structures to counter artillery fire," said Scooter, speaking to BI via video chat from an undisclosed location in central Ukraine.
"Now, we have to train people with the mentality that they are going to constantly be targeted by a loitering munition piloted by a human operator," he said.
FPV drones have emerged as a cheap way to deliver precision strikes against enemy trenches, personnel, and vehicles. Above Ukraine, these weapons are everywhere, with their tiny cameras giving human operators near-constant battlefield surveillance.
Russia and Ukraine have made the FPV drones even more of an issue over the past year by using fiber-optic cables to connect them to their operators, making the small aircraft resistant to most electronic warfare tactics.
"We have had to change our mentality with training completely," Scooter said. "How do I deal with FPVs? Not so much 'how do I deal with artillery fire?"
He said the first thing that he teaches Ukraine's special operators is how to blend in with their surroundings and practice better camouflage techniques. This means that every shiny object needs to be painted, removed, or taped over, with paint covering the hands and face.

Soldiers are also taught how to stay hidden using tree lines or thick forests to their advantage and to find heat sources, such as a car or generator, if they can, to blend in with their surroundings. A Russian drone operator piloting a surveillance drone may not be able to spot the difference between two white blobs on the screen.
Scooter said he trains soldiers in many of the same ways he would snipers or reconnaissance personnel.
"Move fast β don't move too fast," he said. "Don't draw unnecessary attention. The human eye sees movement, shape, and color β in that order. So move carefully, blend in with your surroundings."
"Basically, the same way you might hide from an enemy helicopter is the way you're going to hide from a drone," he added.
Instructors are also teaching Ukraine's special operators to fight the FPV drones with their service weapons β specifically shotguns β as a last resort.
However, these small targets are extremely difficult to hit, and if the drone is close enough, a direct impact could set off its explosive payload, and its forward momentum could spell trouble.
"Small arms fire is seldom effective" against an FPV drone, Scooter said. "But our mentality is that if I can do nothing else, something is better than nothing."
Welcome to Edition 8.02 of the Rocket Report! It's worth taking a moment to recognize an important anniversary in the history of human spaceflight next week. Fifty years ago, on July 15, 1975, NASA launched a three-man crew on an Apollo spacecraft from Florida and two Russian cosmonauts took off from Kazakhstan, on course to link up in low-Earth orbit two days later. This was the first joint US-Russian human spaceflight mission, laying the foundation for a strained but enduring partnership on the International Space Station. Operations on the ISS are due to wind down in 2030, and the two nations have no serious prospects to continue any partnership in space after decommissioning the station.

Sizing up Europe's launch challengers. The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent's incumbent launch service provider, Ars reports. The five small launch companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar's Spectrum rocket failed moments after liftoff from Norway on a test flight in March. None of these companies is guaranteed an ESA contract or funding. Over the next several months, ESA and the five launch companies will negotiate with European governments for funding leading up to ESA's ministerial council meeting in November, when ESA member states will set the agency's budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

Russia is a waning space power, but President Vladimir Putin has made sure he still has a saber to rattle in orbit.
This has become more evident in recent weeks, when we saw a pair of rocket launches carrying top-secret military payloads, the release of a mysterious object from a Russian mothership in orbit, and a sequence of complex formation-flying maneuvers with a trio of satellites nearly 400 miles up.
In isolation, each of these things would catch the attention of Western analysts. Taken together, the frenzy of maneuvers represents one of the most significant surges in Russian military space activity since the end of the Cold War. What's more, all of this is happening as Russia lags further behind the United States and China in everything from rockets to satellite manufacturing. Russian efforts to develop a reusable rocket, field a new human-rated spacecraft to replace the venerable Soyuz, and launch a megaconstellation akin to SpaceX's Starlink are going nowhere fast.

The Russian economy is "on the brink" of entering a recession, the country's economy minister warned on Thursday.
Speaking at the St. Petersburg International Economic Forum, a major annual business event in Russia, Maxim Reshetnikov said data showed the economy "cooling."
When a moderator asked him to describe the state of the economy, he said it seemed that the country was "on the verge of going into recession," according to Russian news agency Interfax.
He later clarified that he wasn't making an outright prediction. "I said that we were on the brink," Reshetnikov said. "From here on out, everything will depend on our decisions."
Reshetnikov has already raised concerns about the direction of the Russian economy. In May, while addressing the State Duma, he said that the economy was cooling so sharply it risked entering a state of economic "hypothermia."
In that address, Reshetnikov urged Russia's central bank to take into account easing inflation when setting interest rates. On June 6, the bank did just that, cutting its key interest rate from 21% to 20%, citing signs of declining inflation.
While inflation is easing slightly, it has remained stubbornly high β now hovering around 10% β since spiking in the wake of Russia's full-scale invasion of Ukraine in February 2022.
The central bank's moves to dampen inflation meant a sharp economic slowdown was inevitable and even intentional, said Brigitte Granville, professor of international economics and economic policy at Queen Mary, University of London.
"The key question has always been whether the Russian economy would undergo a 'hard landing' β meaning inflation would be brought under control at the cost of tipping the economy into recession β or a 'soft landing,' where inflation moderates without triggering a recession," she told BI in an email.
Even if a technical recession did occur, Granville said Russia's labour market remained extremely tight, supporting wage growth. "Even a hard landing would not have serious consequences for the sustainability of Russia's war effort."
Since the start of the war, Russia has gone all in on defense spending.
It's on track to spend about $130 billion on defense, roughly a third of its federal budget, up from 28.3% in 2024.
It's also potentially running low on cash, with one Swedish economist predicting that Russia could run out of liquid reserves as soon as this fall.
The country is still grappling with the effects of Western sanctions, which have targeted its oil and gas exports and largely cut financial institutions off from the international financial communication system SWIFT.
Russia's economy is also suffering from a severe labor shortage, driven in part by the military mobilization, as well as a brain drain of young professionals leaving the country.
According to state media, Russia had a shortfall of some 2.6 million workers at the end of 2024, with shortages hitting the manufacturing, trade, and transportation sectors especially hard.

NATO member Poland has postponed its purchase of 32 S-70i Black Hawk helicopters, with military officials there suggesting the way Russia is fighting in Ukraine shows they're not the right equipment for it to focus on.
General Wieslaw Kukula, the Polish armed forces chief of staff, said at a Friday press conference that "we have decided to change the priorities of the helicopter programs" in order to "better adapt to the challenges of future warfare," Reuters reported.
Poland's deputy defense minister, Pawel Bejda, said on X that his country's military, pilots, and experts were analyzing the geopolitical situation, as well as "the war in Ukraine" and what Russia is buying and equipping its military with.
Poland shares a land border with Ukraine.
Grzegorz Polak, a spokesman for Poland's Armament Agency, which buys equipment for its military, told Reuters that its priorities needed "some correction" and that it might be necessary to buy other equipment instead of the helicopters, "such as drones, or tanks, or some kind of communication."
He also told Polish outlet Defence24 that the armed force's priorities have changed amid evolving threats.
Poland, like other European countries, has warned that Russia could attack elsewhere on the continent.
Its prime minister, Donald Tusk, warned in March that Russia's big military investments suggest it's readying for a conflict with someone bigger than Ukraine in the next three to four years.
Poland is already the highest spender on defense in NATO, as a proportion of its GDP, and has been a major ally of Ukraine throughout the invasion.
Helicopters have played a role in Russia's invasion, with both sides using them to counter drones, offer air support, and launch attacks.
They were particularly effective for Ukraine against Russia's attempts to seize a key airfield shortly after the invasion began in February 2022, and for Russia during Ukraine's 2023 counteroffensive.

But they have also proved vulnerable.
The proliferation of air defenses has meant that they, like other aircraft, have had to hang back from frontline fighting more than in past conflicts, making them far less useful.
Ukraine's success at taking down Russia's Ka-52 helicopters in 2023 meant Russia started using them less. Many were hit by US-provided M142 High Mobility Artillery Rocket System, or HIMARS.
Reports suggest that Russia lost more than 100 helicopters in the first two years of the war.
Ukraine has also destroyed some Russian helicopters at bases far from the front lines.
Even so, losses could have been higher. Mark Hertling, a former commander of United States Army Europe, told BI in January that Russia has been "very poor" in the way it used helicopters and other air assets, but also that Ukraine's air-defense shortages have protected them.
Andrew Curtis, an independent defence and security researcher who spent 35 years as a UK Royal Air Force officer, told BI last year that one lesson Western countries could take from the war is "about the vulnerability of helicopters in the modern battlefield where hiding and seeking is not a child's game, it's a matter of life and death."

The S-70i is a variant of the UH-60 Black Hawk made by PZL Mielec, a Polish company owned by the US's Lockheed Martin.
Poland's plan to buy them began in 2023, under a previous government. The aim was for the helicopters to be used for combat and logistics, and to work with AH-64E Apache Guardian attack helicopters ordered from the US.
Bejda, the deputy defense minister, said the latest move did not involve terminating a contract, as one was never signed.
But it has still led to some domestic issues.
Mariusz Blaszczak, Poland's former defense minister, described the decision as a disgrace in a post on X, saying it would lead to job losses, delays in replacing the country's helicopter fleet, and a loss of interoperability because Poland's military already uses some Black Hawks.

The postponement comes after Poland spent years investing in helicopter technology, including ordering 96 Apache Guardians in a deal signed last year, and 32 Leonardo AW149s in a deal signed in 2022.
Bejda said Poland would still prioritize some helicopters, including training and combat helicopters, a heavy transport helicopter, and search and rescue helicopters.
But the government, which took office at the end of 2023, clearly views increasing the fleet as less important than investing in other military assets.
The war in Ukraine has led Western countries to boost their own defense spending and to change their priorities, including through buying more air defenses and drones, investing more in tanks, and even bringing back old types of training like trench warfare.
Kosmos 482, a Soviet-era spacecraft shrouded in Cold War secrecy, will reenter the Earth's atmosphere in the next few days after misfiring on a journey to Venus more than 50 years ago.
On average, a piece of space junk the size of Kosmos 482, with a mass of about a half-ton, falls into the atmosphere about once per week. What's different this time is that Kosmos 482 was designed to land on Venus, with a titanium heat shield built to withstand scorching temperatures, and structures engineered to survive atmospheric pressures nearly 100 times higher than Earth's.
So, there's a good chance the spacecraft will survive the extreme forces it encounters during its plunge through the atmosphere. Typically, space debris breaks apart and burns up during reentry, with only a small fraction of material reaching the Earth's surface. The European Space Agency, one of several institutions that track space debris, says Kosmos 482 is "highly likely" to reach Earth's surface in one piece.

Welcome to Edition 7.39 of the Rocket Report! Not getting your launch fix? Buckle up. We're on the cusp of a boom in rocket launches as three new megaconstellations have either just begun or will soon begin deploying thousands of satellites to enable broadband connectivity from space. If the megaconstellations come to fruition, this will require more than a thousand launches in the next few years, on top of SpaceX's blistering Starlink launch cadence. We discuss the topic of megaconstellations in this week's Rocket Report.

So, what is SpinLaunch doing now?Β Ars Technica has mentioned SpinLaunch, the company that literally wants to yeet satellites into space, in previous Rocket Report newsletters. This company enjoyed some success in raising money for its so-crazy-it-just-might-work idea of catapulting rockets and satellites into the sky, a concept SpinLaunch calls "kinetic launch." But SpinLaunch is now making a hard pivot to small satellites, a move that, on its face, seems puzzling after going all-in on kinetic launch and even performing several impressive hardware tests, throwing a projectile to altitudes of up to 30,000 feet. Ars got the scoop, with the company's CEO detailing why and how it plans to build a low-Earth orbit telecommunications constellation with 280 satellites.
