• The US Army is expanding its use of high-altitude balloons for surveillance and communications.
• The balloons can operate 60,000 to 100,000 feet above Earth, providing space-like capabilities.
• Army officials plan more experiments as the service expands its space warfare ranks.

The US Army is looking to expand its use of high-altitude balloons as the service builds out its capabilities near and in outer space.

These balloons operate in the stratosphere, roughly 60,000 to 100,000 feet above Earth, the space in between where conventional aircraft fly and satellites. Army officials say they see an opportunity to use the balloons to deliver satellite-like surveillance and communication capabilities closer to the battlefield.

Lt. Gen. John Rafferty, commander of Army Space and Missile Defense Command, said he was initially skeptical of the technology. He recalled hearing proposals to use high-altitude balloons while serving in what was then Army Futures Command and questioning whether they'd prove practical.

The general's view, however, changed after he saw the balloons hold their positions and conduct high-altitude surveillance during a training exercise.

"I went from nowhere to a huge believer very quickly once I saw them in action," Rafferty said at this week's Association of the United States Army conference in Washington, DC.

The Army is exploring a range of balloon systems for different missions, from surveillance and communications to supporting long-range strikes.

Col. Joseph Mroszczyk, who oversees the efforts to integrate emerging space capabilities into Army operations as the director of Transformation Integration Space Superiority, said at AUSA that he wants a "family of stratospheric systems."

Unlike satellites, which travel set paths in orbit, high-altitude balloons can exploit different wind currents to maneuver or maintain a presence over an area of interest, he said.

Mroszczyk said the Army could use favorable winds to position balloons carrying sensors, communications equipment, or payloads supporting strikes.

"What that enables us to provide is space-like capabilities, really exploiting a transition point between what is normally considered the aerial layer and the space domain," he said.

Operating at those altitudes could give the Army persistent coverage across large areas from the stratosphere without relying exclusively on satellites or conventional aircraft.

The Army plans to conduct multiple experiments involving various stratospheric systems over the coming year, building on tests conducted in Europe and the Pacific. The service has also experimented with the technology alongside combat operations in the Middle East, a senior Army official told Breaking Defense earlier this week.

Those efforts followed the cancellation of a large-scale balloon demonstration planned for the Indo-Pacific last year.

The growing interest in high-altitude balloons comes as the Army expands its role in space and near-space operations, with ground forces increasingly reliant on space-based capabilities for navigation, communications, and intelligence.

Ukraine has received undisclosed assistance from Poland as it struggles to defend against increasingly intense Russian drone and missile attacks, President Volodymyr Zelenskyy hinted during a meeting with Polish Prime Minister Donald Tusk in Brussels on 15 October, Radio Svoboda reported.

Ukraine’s air defense needs are greater than at any point since 2022, as intensified Russian drone and missile attacks strain existing systems and expose shortages of interceptor missiles. With US support increasingly uncertain amid tensions between Kyiv and Washington, European military aid is becoming more critical to Ukraine’s ability to defend its cities and infrastructure.

Zelenskyy thanked Warsaw for its support, suggesting that some assistance had to remain confidential. He also specifically mentioned 20 mm ammunition, which Ukraine needs to defend its cities against Russian attacks.

“Sometimes this has to stay between the two of us,” Zelenskyy said, thanking Tusk for the aid.

European support increasingly important amid US rift

Ukraine is facing mounting pressure on its air defenses as Russia increases the scale of its aerial attacks. Ukrainian forces are also struggling with shortages of interceptor missiles, particularly Patriot missiles needed to counter Russian ballistic strikes, leaving the country vulnerable to further attacks.

The need for additional support comes amid growing uncertainty over US assistance under President Donald Trump. Washington has taken steps that have strained ties with Kyiv, including easing some restrictions on Russian fuel and pressing for an energy ceasefire that Ukraine says Russia has continued to violate. 

Recent disruptions to US-linked intelligence and satellite support have also raised concerns about Ukraine's ability to detect and counter Russian attacks.

As uncertainty over Washington's role grows, European military assistance is becoming increasingly important for Ukraine's defense.

Defense cooperation continues despite political tensions

Tusk reaffirmed Poland's commitment to supporting Ukraine, saying Kyiv could count on Poland and the European Union. He also opposed easing EU sanctions against Russia, arguing that Europe should not take steps that help Moscow finance its war.

The meeting also came amid strained relations between Kyiv and Warsaw over historical disputes. However, Poland's government has maintained that these disagreements should not undermine military support for Ukraine, whose ability to resist Russian aggression is closely tied to Poland's own security.

Temporary restrictions on aircraft arrivals and departures were imposed at 27 Russian airports, Deutsche Welle reported on 16 October, citing its own calculations based on reports from Russia’s Federal Air Transport Agency.

Ukrainian President Volodymyr Zelenskyy warned airlines on 1 September that “Russian airspace is becoming completely unsafe.” Overnight, most of the airspace over European Russia was closed.

By morning, more than 200 flights had been canceled or delayed at Moscow airports, Deutsche Welle reported, citing figures compiled by a Russian Telegram channel.

The list included airports in the capital. All four Moscow airports temporarily suspended arrivals and departures, the Russian outlet Astra reported on 16 October. Russian authorities said they had shot down dozens of drones, while flights were delayed and diverted to alternate airfields, according to the report.

Massive drone attack on Russia: 644 UAVs in one night, 94 shot down near Moscow

The temporary airport shutdowns were likely a consequence of a massive drone attack on Russia. From 8:00 p.m. on 15 October to 8:00 a.m. on 16 October, Russian air defenses allegedly intercepted and destroyed 644 Ukrainian unmanned aerial vehicles across 26 Russian regions, occupied Crimea, and the Black Sea, according to Russia’s Defense Ministry.

According to the list of regions published by the Russian Defense Ministry, the drone attacks covered a vast area of Russia, from regions bordering Ukraine to the Moscow region, the Volga region, the country’s northwest and southern regions, as well as occupied Crimea and the Black Sea.

Russian air defenses shot down a total of 94 drones approaching Moscow over the evening of 15 October and overnight, according to calculations by the Russian outlet RBC Radio, citing statements by Moscow Mayor Sergey Sobyanin.

In the Kaluga region, air defenses destroyed 27 drones over the evening and night, the regional governor reported. At 9:27 a.m., he updated the figures, saying another 48 UAVs had been shot down overnight, bringing the total to 75. According to preliminary information, there were no casualties or infrastructure damage.

In the Tula region, air defenses allegedly destroyed a total of 32 Ukrainian drones. There were no casualties, according to regional Governor Dmitry Milyaev in his Telegram channel.

In the Vladimir region in western Russia, authorities repelled drone attacks overnight. In the city of Vladimir, a drone attempted to attack a heating infrastructure facility, but the attack was stopped, Vladimir Region Governor Alexander Avdeyev reported. Minor damage was reported, but there was no information about casualties.

Ukraine has not yet commented on its involvement in the attacks.

The practical consequences of canceled Russian flights

Passengers on flight SU6312 from Kaliningrad to Moscow were unable to land in Moscow because of airspace closure, so the aircraft was diverted to Nizhny Novgorod, Terravia reported. After landing, passengers remained on board for about two hours before being allowed to disembark at 3:30 a.m. Instead of continuing their journey to Moscow by air, they were supposed to be transported by bus, with the trip expected to take about seven hours, the outlet reported.

Passengers were not provided with food or drinks, and one woman could not find a seat on the bus, so she purchased a ticket for an early-morning train herself.

Since the beginning of the year, all four Moscow airports have been completely shut down simultaneously at least 19 times, the Russian outlet Agentstvo reported. During the first 14 days of October, the restrictions lasted 101 hours and 38 minutes, compared with 46 hours and 33 minutes in September, according to the report.

• Ukraine's access to military-grade Starlink services was suddenly disrupted this week.
• Kyiv said the disruption affected critical Ukrainian drone operations.
• Ukrainians say the incident exposes the risks of relying so heavily on a single communications platform.

The sudden disruption to Ukraine's access to military-grade Starlink services this week shows the risks of overly relying on any single platform, particularly one beyond Kyiv's control, for mission-critical battlefield communications, Ukrainian soldiers, officials, and defense companies told Business Insider.

With those risks front of mind, Ukrainians are working to diversify military-related communications platforms beyond Starlink.

Ukrainian officials and soldiers were surprised on Wednesday by an unexpected disruption to Starshield, SpaceX's dedicated satellite network for military services. Defense ministry sources said speeds were restricted above 100 miles per hour, though some units experienced a loss of connectivity at speeds as low as 45 mph.

Services appeared to have been at least partially restored by Thursday. The full extent of the disruption remains unclear, but the incident has left some Ukrainians feeling uneasy.

Yehor Cherniev, deputy chairman of the Ukrainian parliament's national security, defense, and intelligence committee, told Business Insider that the disruption underscores the risks of relying on a single communications platform. He said Kyiv is working to diversify its sources, but declined to specify how.

Yuriy, an officer with Ukraine's National Guard, told Business Insider that his units use Starshield to support drone operations, and several missions were spoiled during the disruption. He asked to be identified only by his first name for security purposes.

Yuriy said that while Starlink services are useful, the disruption exposes their unreliability. He said he would try to find alternate communications systems.

Alternatives to Starlink could be hard to find, though. Eutelsat, a large French satellite operator, saw its shares surge after this week's disruption, but Ukrainians say there is nothing else quite like what SpaceX offers.

"There is no working alternative to Starlink," said Dimko Zhluktenko, a soldier with Ukraine's 413th Unmanned Systems Regiment, calling it "an outstanding product."

"No direct competitor comes close," he told Business Insider, adding that "Europe has nothing comparable at this level of battlefield readiness."

SpaceX did not respond to requests for comment from Business Insider this week.

Ukraine relies on Starlink for battlefield communications and drone warfare, a dependence that was underscored by the disruption. Defense ministry sources said the disruption complicated important drone operations, including mid-range strikes, air defense intercepts, and front-line logistics.

Ukraine uses both Starshield and Starlink, SpaceX's commercial satellite internet service, to extend the reach of its drones, maintain stable communications in electronically contested environments, and conduct remote operations far beyond the front lines.

Satellite connections allow operators to control drones and receive live video without relying on traditional radio links, which have limited ranges and are much more vulnerable to electronic warfare interference.

The tech has been integrated into systems such as Perennial Autonomy's Hornet drones, as well as Ukrainian naval drones used to strike Russian targets in the Black Sea, among others.

Many Ukrainian defense companies have integrated Starlink services into their broader infrastructure, even if their products don't necessarily depend on it for operations.

Some firms, such as SkyFall, maker of the widely used P1-SUN interceptor drone, told Business Insider that they have developed their own communication methods or use alternative systems to avoid scenarios where a single technology outside Ukrainian control could become a significant point of failure, as it did this week.

"Depending on a single solution is very risky. Especially if you don't have full control over it," a spokesperson for Wild Hornets, the firm behind the popular Sting interceptor drone, told Business Insider. "Especially when it comes to something as critical on the battlefield as communications."

The spokesperson said this is "exactly why our ecosystem is built around our own communications technology and is open to various solutions when it comes to internet connectivity."

For anyone working with technologies that are dominated by a single provider, the risks are clear, said the head of hardware research and development at BlueBird Tech, a defense firm that makes drones and robots. They told Business Insider that Starlink has virtually no competitors because of its coverage, cost, availability, and ease of use.

BlueBird Tech uses Starlink services but is trying to avoid tying its products completely to any single technology. "We're actively exploring ways to introduce redundancy and potentially replace these components in the future," they said, speaking anonymously due to security concerns.

They said that potential workarounds include LTE or 5G technology, mesh networks with relay points, and laser communications. "Research teams around the world are working on these technologies," they said, "although none of them should be seen as a universal replacement for Starlink across every operational scenario."

When the disruption first occurred on Wednesday, some Ukrainian and foreign officials initially blamed SpaceX, led by Elon Musk. However, the world's richest man said on X on Wednesday that because Starshield is operated by the US government, any limits on speed would be a decision for the Pentagon or President Donald Trump.

A senior US official told Business Insider on Thursday that "no such request was ever made by" Trump. Reuters reported that the order came from inside the White House.

Starlink has delivered Kyiv an important battlefield advantage, especially since SpaceX cracked down on Moscow's ability to use the terminals earlier this year. The system, however, does not work in Russia, so Ukraine is limited to using its services over its own territory and Russian-occupied lands.

Ukraine has been unable to use Starlink for its long-range drone strikes that have wreaked havoc on Russian energy sites. Trump has pushed Kyiv to stop its attacks as he attempts to use Russian oil to lower gas prices.

Ukraine has found itself facing mounting pressure from the US, once a top supporter, as it continues to grapple with Russian missile and drone strikes amid severe shortages of critical air defense interceptors. The Starlink outage has only compounded Kyiv's anxieties as it anticipates yet another tough winter.

"Starlink is a major card on the battlefield," Zhluktenko said. "You can fight without it — even successfully — as the Russians show, but less effectively, at higher cost, and with constant communication headaches, above all for unmanned systems."
