What did the Pentagon inspector general decide?
The Pentagon's inspector general has declined to investigate how Starlink and Starshield service to Ukraine was slowed in October. In a letter dated Tuesday, Oct. 27, the office told nine senators that their questions belonged with the Air Force and Space Force. The Associated Press obtained the letter, and CNN and ABC News reported the same document.
The refusal leaves Congress without the independent review it requested. The inspector general can subpoena records and question officials across the department. The Air Force and Space Force sit inside the same civilian chain of command that the senators want examined.
Sen. Jeanne Shaheen, the ranking Democrat on the Senate Foreign Relations Committee, called the decision concerning. “It is concerning that the Inspector General has apparently decided not to investigate,” she said of the disruptions. Ukraine relies on those links to protect civilians, she added. She also called for “an independent accounting and review to determine responsibility.”
The inspector general's office framed the dispute as a contract question. Platte B. Moring III, the inspector general, wrote that the services were “better suited to address the matters raised in your letter.” A spokesperson, Mollie Halpern, said the office “carefully considered the congressional request.” She said it could reconsider if new information emerges.
The letter followed an unusual round of handoffs. According to ABC News, the inspector general first suggested that the senators take their questions to the Pentagon's under secretary for policy. That office then sent the request back, describing the disruptions as a contractual matter for the two military services.
The original request was broad. The nine senators asked the watchdog to establish whether the Defense Department or its contractors caused the restrictions. That is the scope the inspector general declined to take on.
An inspector general review carries tools that a service inquiry does not. The office can subpoena records across the department and publishes public reports that Congress can cite. A contracting officer answering a senator's letter has no equivalent reach.
Moring was confirmed as inspector general in December 2025. His office now calls itself the Department of War Office of Inspector General.
What is Starshield, and why does Ukraine depend on it?
Starlink is SpaceX's commercial satellite internet service, delivered from low-Earth-orbit satellites. Starshield is the military-grade version. It runs on the same constellation but is sold to the US government under Defense Department terms.
The Space Force bought Starshield access in October 2023 through a $70 million task order. The deal covered a global subscription for land, maritime, stationary and mobile users, according to Air & Space Forces Magazine. The magazine reported that Starshield differs from commercial Starlink because of “unique Department of Defense terms.”
SpaceX markets Starshield around Earth observation, communications and hosted payloads. The Space Force order bought connectivity as a service, not a set of satellites. That is why the contract's terms matter more than the hardware.
Ukraine uses both services. Starlink lets units coordinate where radio and mobile networks are unreliable. Starshield carries drone video, targeting data and control links for interceptor drones, according to the BBC.
Satellite control matters because electronic warfare degrades conventional radio links. A drone linked to a satellite can be flown beyond line of sight and can send video back to its crew. A speed cap that severs that link removes the crew's control at the moment it is needed.
That makes terminal speed a tactical variable rather than a billing detail. Terminals in motion lose their connection above a set velocity. Ukrainian operators reported a ceiling of about 100 mph, or 160 km/h, from the night of Oct. 13.
During the restriction, Ukrainian officials said links failed above roughly 161 km/h. After restoration on Oct. 24, the defense minister said drones could again fly faster than 400 km/h.
What happened between October 13 and October 24?
The inspector general is now the second office to decline the question. The first was the Pentagon's policy office, which sent it back as a contract matter.
Ukrainian officials say the change arrived without warning during a Russian missile barrage. A presidential adviser, Serhii Beskrestnov, wrote that units were not notified in advance and that several missions failed. SpaceX has not published a technical explanation of the speed limit.
- •Oct. 13–14: SpaceX imposes a speed limit of about 100 mph on terminals in motion, according to Ukrainian officials and BBC reporting.
- •Oct. 15: Nine senators, led by Republican Thom Tillis and Democrat Jeanne Shaheen, ask the inspector general for an urgent investigation.
- •Oct. 16: Germany's foreign minister says Berlin pays SpaceX for Ukraine's access and expects the service to work.
- •Oct. 19–22: Senators ask SpaceX when it told Germany about the change, and urge the Pentagon to expand the Starshield contract.
- •Oct. 22: Trump says the service is running again at full speed. The Wall Street Journal reports that he asked Musk to restore it.
- •Oct. 23: Zelenskyy says limits remain at about 100 mph, despite a promise of restoration within 48 to 72 hours.
- •Oct. 24: Ukraine's defense minister reports a stable connection and drone speeds above 400 km/h.
- •Oct. 27: The inspector general declines to investigate.
Who is responsible for the slowdown?
Four accounts are on the record, and they do not fit together. The dispute turns on who controlled the system that was limited, and on whether a commercial contract term could justify the change.
Musk first blamed the US government. On Oct. 14 he wrote that Starshield systems “are owned and controlled by the US government.” He added that any limits on speed or usage are decided by the military and ultimately the president. Ten days later he said SpaceX had restricted the commercial Starlink service because Ukraine violated its terms of service. “That loophole was closed last week,” he wrote, while insisting that Starshield is separate and government-controlled.
The administration denied ordering anything. Secretary of State Marco Rubio said no one in the US system had requested changes to the service. Defense Secretary Pete Hegseth said the Pentagon had not pulled anything back, then pointed to the contract. “There are terms of service that ultimately need to be complied to,” he told reporters. He said Starlink had the option to make those decisions. Vice President JD Vance suggested that Musk was caught between two states.
Rubio went further than a denial. He said the president does not run SpaceX and cannot direct the company to do anything. Vance made a similar argument. He said Musk runs a private corporation and should not be caught between two states without government direction.
Trump's own account shifted. He first said: “I don't know if it was anybody, but it wasn't me, and I don't think it was Elon.” He later said: “I guess the bottom line, he put it back.” He did not say who had ordered the limit.
Zelenskyy rejected the terms-of-service explanation. He said the restrictions applied only to Ukraine, not to Starshield terminals in European Union countries. He called it “a planned operation.” In an NBC interview, he said the order came from the American government and SpaceX carried it out. He also said Kyiv still had no explanation for the change.
The timing was not accidental, according to Ukrainian officials. The cap landed during a row over Ukrainian strikes on Russian oil refineries. Trump had announced an energy ceasefire and a deal for Russian diesel. Zelenskyy said he paused strikes for three days, then resumed them, according to the BBC.
Musk had promised a year earlier that Starlink would never turn off its terminals in Ukraine, Defense One reported. That pledge is now part of the political problem for the administration. The private control he described is the same control the senators want examined.
The senators found the explanation incomplete for a structural reason. If Washington controls Starshield, then a dispute over Starlink's civilian terms should not reach the military tier. Their Oct. 19 letter argued that a terms-of-service violation should not affect Starshield, which the government controls, according to Defense One.
The Associated Press reported that congressional aides see a longer pattern. Concerns about Musk's influence over Ukraine's connectivity helped prompt the creation of Starshield in the first place. The same dependence now sits at the centre of the dispute.
Why does the refusal matter beyond Ukraine?
The decision leaves no independent finding on who authorized a wartime service cut to an ally. That gap has consequences for allies that pay for US satellite capacity and for the companies that sell it.
Germany funds Ukraine's access. Its foreign minister, Johann Wadephul, said in October that Berlin is paying SpaceX and therefore expects the service to work. Canada's prime minister, Mark Carney, also criticized the decision, according to Defense One. Both were reacting to a service their governments rely on but do not operate.
That is the practical problem for allies. When a government buys capacity through a US contract, it inherits whatever discretion the contract leaves with Washington or the vendor. The senators' Oct. 19 letter pressed the point, asking SpaceX when it had notified the German government about the decision.
Former US officials say the episode damages the case for buying American. A retired general, Ben Hodges, said he believed Musk thought he was acting in line with the White House's wishes. A former senior acquisition official said switching off service during combat creates doubt for planners and encourages competitors.
Europe cannot replace Starlink quickly. Defense One noted that Europe has no public or private satellite communications system able to substitute overnight. Eutelsat OneWeb, SES and Iridium could pick up government business. The article also compared the episode to India's loss of GPS access in the 1999 Kargil conflict. That loss pushed Delhi to build its own navigation system.
Congress is not treating the matter as closed. Sen. Richard Blumenthal announced a new inquiry, and Sen. Adam Schiff said on NBC's Meet the Press that Hegseth should testify. “Somebody is lying here,” Schiff said. “Maybe they're all lying in different ways, but we need to find out.”
What are the limits of the public record?
The inspector general's letter has not been published. Its contents rest on copies obtained by the Associated Press, CNN and ABC News. The office and Shaheen have also commented.
The letter is also not a finding of wrongdoing. It is a decision not to look, which means the conflicting public accounts remain the only record available to the public.
No public response from the Air Force or Space Force appears in the reporting. It is not known whether either service has opened a review. Nor is it clear whether they will answer the senators' questions.
Key contract details remain classified or undisclosed. The public record does not show the exact speed terms or the notification rules for allied governments. It also does not say who inside the government can direct a change.
There is no technical account from SpaceX either. The company has not published details of the change, why it was applied on Oct. 13, or how it was reversed after ten days. It is not known whether it answered the senators' questions about Germany.
Most importantly, no evidence has been made public that ties Trump personally to the order. The Wall Street Journal reported that he asked Musk to restore service, not that he requested the limit. Musk's and the administration's accounts conflict on who held the switch.
Casualty claims are also unresolved. Zelenskyy said people were killed because interceptors dependent on the network failed. Those claims have not been independently verified, and the reporting reviewed here does not quantify them.
What happens next in the Starlink investigation?
The immediate question is whether the Air Force and Space Force will answer in writing. The inspector general's letter directs the senators there, so the services now own the response. A refusal or a narrow reply would sharpen the case for hearings.
It is also unclear how the services will treat the request. They could treat it as a contract complaint, which would keep details confidential. Or they could treat it as a policy question, which invites scrutiny.
Congress has several routes open. Blumenthal's inquiry can request documents and testimony. Schiff wants Hegseth before the Senate, though that depends on committee control after the November midterms. The Senate can also attach conditions to Starshield funding.
A hearing would put the dispute on the record. It would let senators question Hegseth and possibly Musk under oath, and it could force the contract terms into public view. The letters so far have not done that.
Contract policy is already in play. In their Oct. 22 letter, senators urged the Pentagon to expand the Starshield contract and restore unlimited-speed service. The Pentagon has not responded publicly to that request.
The inspector general has left the door open. Halpern said the office may reconsider if new information comes to light. A report from another oversight body, or new documents from SpaceX, could reopen the question.
Allies will watch the contract terms as closely as the politics. If Washington cannot explain who may slow a paid service, buyers will price that risk into their plans.
