Abstract:
According to a Reuters report on October 15, 2026, multiple officials familiar with the matter revealed that the directive to restrict the Ukrainian military’s use of SpaceX’s “Starshield” satellite communications services came from within the U.S. White House. Senior U.S. Department of Defense officials reportedly received notice to reduce the service's ability to support the Ukrainian military. However, it is unclear which White House official made the decision, and there is no clear information on which department is responsible for implementation.
Two U.S. officials and a Western official with knowledge of the situation disclosed the news to Reuters. The sources requested anonymity because of the sensitive government decisions involved. In response to inquiries about the restrictive directive, a senior U.S. official said President Trump himself had never made such a request. The White House did not respond to questions about whether other government officials had issued relevant orders.
The restrictions involve satellite communications systems used by the Ukrainian military. The Ukrainian military relies on such systems to maintain battlefield communications and provide the data connections needed to navigate and control some drones. Ukrainian officials said this week that military-grade satellite communication terminals had failed to work properly when installed on high-speed moving platforms, affecting drones that rely on satellite connections for flight control.
Ukrainian officials said the relevant restrictions have affected a variety of military operations, including strike missions targeting Russian troops and their logistics facilities, as well as interception drone operations to intercept Russian "Geranium" series of unmanned attack aircraft. Since some UAVs need to continuously maintain satellite connections during high-speed flight, once the communication terminal loses connection while moving, it may affect mission execution or even cause mission failure.
A source from the Ukrainian Ministry of Defense later stated that the relevant terminal has resumed work in a mobile state, but the speed is limited, with a maximum speed of about 100 miles per hour, equivalent to 160 kilometers per hour. This means that for drones or other mobile platforms with speeds above this threshold, satellite connections may not work as intended.
Star Shield is developed by SpaceX, an American space exploration technology company, specifically for government and national security customers. Its main service targets include the U.S. Department of Defense. It is based on SpaceX's "Starlink" low-orbit satellite constellation, but provides corresponding services to government and military users. The U.S. Department of Defense is one of StarShield's largest customers and has invested heavily in related satellite communications and national security projects.
Although Starshield and Starlink share satellite network infrastructure, their service positioning is not exactly the same. Starlink operates primarily as a commercial satellite internet service, while StarShield is targeted at government and national security uses. The Ukrainian military uses relevant satellite communication capabilities to carry out battlefield communications, drone control and other tasks, but its specific scope of use is subject to conditions set by the U.S. government.
SpaceX CEO Elon Musk stated on the social platform Musk also emphasized that Starlink is a commercial service owned and controlled by SpaceX, its use is limited, and it should not be used for offensive military operations.
SpaceX did not respond to Reuters' request for comment on the restrictions. The U.S. Department of Defense and the Ukrainian Embassy in Washington also did not respond to relevant inquiries.
This incident occurred at a time when relations between the United States and Ukraine are further deteriorating. Relations between the two sides have been tense recently, focusing on Ukraine's attacks on Russian energy infrastructure, U.S. efforts to promote a ceasefire between Russia and Ukraine, and whether Washington will continue to provide military and intelligence support to Kiev.
On October 9, representatives from the United States, Ukraine, Europe and the World Bank held talks in Miami. According to a person familiar with the meeting, U.S. President Trump’s son-in-law Jared Kushner and the Trump administration’s special envoy for the Middle East Steve Witkoff took a tougher stance on Ukraine during the talks. The United States expressed dissatisfaction with Ukraine's continued attacks on Russian oil refining facilities and believed that Kyiv had not fully considered Washington's request for it to stop such actions.
Trump has recently repeatedly asked Ukraine to stop attacking Russian oil refineries and linked related actions to rising global energy prices. The U.S. government hopes to ease market pressure and create conditions for Russia-Ukraine negotiations by increasing the supply of Russian diesel and other energy products. However, the reasons for rising energy prices are controversial. Some experts believe that the war between the United States, Israel and Iran, as well as the resulting attacks on energy facilities and obstruction of transportation in the Strait of Hormuz, are the main reasons for the recent pressure on the energy market.
Meanwhile, the U.S. government announced an arrangement that would allow Russia to supply diesel to the U.S. and other markets. The decision sparked controversy in the United States, with critics worried that it would allow Russia to gain more revenue without having to make corresponding concessions to end the war. According to relevant reports, this arrangement involves a supply plan for more than 2.25 million barrels of diesel.
In addition to energy issues, new frictions have also emerged between the two sides in military and intelligence cooperation. It was previously reported that U.S. officials had privately warned Ukraine that Washington might stop providing some intelligence support to Kiev if it continued to attack Russian energy infrastructure. The early warning information provided by the United States about Russian ballistic missile launch activities plays an important role in Ukraine's judgment of the direction of attacks, organizing air defense operations, and timely issuance of civil defense warnings.
Ukrainian President Volodymyr Zelenskiy once complained that Ukraine did not receive the early warning information it had been able to obtain in the past before Russia launched some ballistic missile attacks. Ukraine believes that such information is crucial to protecting civilians and reducing casualties caused by attacks. However, U.S. President Trump previously stated that the United States is still providing intelligence to Ukraine. There is still uncertainty about whether intelligence sharing will be adjusted and the specific scope of the adjustment.
After news broke that Star Shields services were restricted, Ukraine began to seek explanations from high-level officials in the U.S. government. A senior Ukrainian official said that Ukraine contacted senior officials from the White House, the U.S. State Department, and the Department of Defense on October 14 and 15, hoping to clarify the source and reason for the restrictive measures. The reply received by Ukraine was that the decision came from the White House.
For Ukraine, this incident exposed its high dependence on the satellite communication system controlled by the United States. In the past few years, satellite Internet has become an important part of the Ukrainian military's communication system. It has provided support for information transmission between troops and some drone operations when traditional communication facilities have been destroyed and frontline network conditions are poor.
Drones are playing an increasingly important role in the Russia-Ukraine conflict. Ukraine not only uses drones to attack Russian troops, command facilities and logistics targets, but also deploys a large number of interceptor drones in an attempt to respond to attacks by Russian drone attack aircraft in a relatively low-cost manner. Once the satellite communication connection is restricted, it may affect the navigation and control of drones during high-speed flight, thereby changing the performance of related tasks.
It is worth noting that this incident does not involve commercial service adjustments purely decided by SpaceX. According to Musk, the Star Shield system is owned and controlled by the U.S. government, and usage restrictions are determined by the U.S. military or the president. This means that even if SpaceX is responsible for the development and operation of related technologies and services, how the Ukrainian military can use this system still depends on the policies and scope of authorization set by the US government.
The U.S. government has not publicly explained the complete decision-making process for this restriction, nor has it confirmed which official made the relevant request. A senior U.S. official specifically denied that Trump himself had requested the restrictions, but that statement did not rule out the possibility that other White House officials were involved in the decision-making. The White House did not provide further explanation, and the Department of Defense did not publicly explain the specific implementation arrangements after receiving the directive.
At present, relevant terminals used by the Ukrainian military have been reported to have restored some connection capabilities in mobile states, but the speed limit of 160 kilometers per hour still restricts some high-speed drone operations. Whether this incident is a temporary technical or policy adjustment, or whether it is part of changes in the conditions for U.S. military support to Ukraine, remains to be further confirmed.
On a broader level, the controversy reflects a practical problem faced by Ukraine in the war: when critical communications capabilities rely on infrastructure controlled by a foreign government, the user cannot fully control its availability, even if the relevant technology can significantly improve battlefield efficiency. Satellite communications are not only a technical service, but may also directly affect drone operations, air defense responses and battlefield information delivery in modern warfare.
As the differences between the United States and Ukraine over attacks on energy facilities, ceasefire arrangements, and intelligence cooperation continue to widen, the Star Shield service restrictions incident has further deepened Kyiv's doubts about the stability of U.S. support. However, until the U.S. government releases more information, it is still not possible to determine the full motivation for this decision, nor can it be concluded based on this incident alone that the U.S. has comprehensively changed its military support policy for Ukraine.
