Pentagon Watchdog Refuses Starlink Investigation as Questions Grow Over Musk’s Control of Ukraine’s Military Communications
The Pentagon’s independent inspector general has declined a bipartisan request to investigate restrictions imposed on Starlink and Starshield satellite communications in Ukraine, leaving unresolved questions about who authorised the disruption, whether Washington was involved, and how much control Elon Musk exercises over infrastructure essential to Ukraine’s defence.
The decision, disclosed by the Associated Press on 28 October, follows complaints from Ukrainian officials that restrictions introduced earlier this month disrupted military drone operations, including attempts to intercept high-speed Russian attack drones.
Nine US senators, comprising five Democrats and four Republicans, had requested an independent investigation into the circumstances surrounding the interruption.
Instead, Pentagon Inspector General Platte Moring III informed lawmakers in a letter dated 27 October that the questions would be better addressed by the US Air Force and Space Force.
The response has intensified a dispute extending beyond Ukraine’s battlefield communications to the relationship between the American government, its defence contractors and the private companies supplying critical military technology.
Senators Demand Answers Over Starlink Restrictions
The investigation was requested by senators Jeanne Shaheen and Thom Tillis, alongside seven colleagues from both parties.
Their 15 October letter sought to establish whether Pentagon officials or other US government representatives had authorised, approved or received advance notice of changes affecting Ukraine’s satellite communications.
The senators also raised concerns about reported disruptions to intelligence-sharing and early-warning arrangements, including allegations that American personnel in Ukraine experienced difficulties reaching shelters during Russian air raids.
They wanted investigators to determine whether these incidents were connected, whether contractual obligations had been breached and whether SpaceX had acted independently.
Shaheen, the senior Democrat on the Senate Foreign Relations Committee, criticised the inspector general’s decision.
She argued that contradictory explanations from the Trump administration and SpaceX made an independent examination necessary to establish responsibility and prevent further disruptions.
Mollie Halpern, spokeswoman for the inspector general’s office, defended the decision, saying the congressional request had been carefully considered and that the issues were more appropriately handled within the Pentagon.
She nevertheless left open the possibility of reconsideration if additional information emerged.
Who Ordered the Slowdown?
The controversy began around 14 October, when Ukrainian forces reported that equipment using Starlink and its military-oriented counterpart, Starshield, was losing connectivity when travelling at higher speeds.
The restrictions were particularly damaging to unmanned aircraft.
Ukraine reported communications failures at movement speeds of approximately 130–161 kilometres per hour, limiting the effectiveness of certain strike drones and jet-powered interceptors used against Russian attacks.
According to The Wall Street Journal, Musk personally authorised the slowdown, although accounts differed over whether President Donald Trump or senior administration officials knew about the decision beforehand.
Musk subsequently acknowledged that SpaceX had imposed restrictions on commercial Starlink services, alleging that Ukrainian forces had violated the company’s terms of service by using the network for offensive operations.
Ukrainian representatives disputed that explanation.
Musk also maintained that Starshield was a separate system controlled by the US government, suggesting that decisions affecting its operation ultimately rested with American authorities.
Trump denied ordering the restrictions.
The differing accounts have left unanswered whether the interruption resulted from a corporate decision, an American government directive or a combination of the two.
Trump Intervention and Restoration of Services
The Wall Street Journal reported that Trump contacted Musk on 21 October and requested the removal of the restrictions.
Although some improvement followed, Ukrainian officials initially reported that the systems had not returned to full functionality.
On 24 October, however, Ukraine’s Ministry of Defence confirmed that normal performance had been restored, with stable communications recorded on equipment moving at speeds exceeding 400 kilometres per hour.
President Volodymyr Zelensky subsequently confirmed the restoration and thanked American officials and partners involved in resolving the problem.
The restoration addressed the immediate operational disruption but did not establish who had originally authorised the restrictions.
Private Technology and Military Accountability
The episode has renewed scrutiny of the Pentagon’s dependence on SpaceX, whose satellite networks have become important components of Ukrainian battlefield communications.
Starshield was developed to serve government and national security requirements, including military applications. Nevertheless, the dispute illustrates the difficulty of determining responsibility when essential defence capabilities depend on systems developed and operated by commercial contractors.
The issue has historical precedent.
In 2022, Musk ordered restrictions on Starlink availability in parts of Russian-occupied Ukraine, citing concerns that expanded military use might escalate the conflict.
The latest incident has prompted renewed discussion of whether contractual arrangements provide sufficient safeguards against unexpected interruptions.
Following the October restrictions, Finnish satellite company ICEYE announced discussions with Nokia and Ukraine’s Defence Ministry concerning cooperation on sovereign satellite communications.
Such alternatives could eventually reduce dependence on individual commercial providers, although developing and deploying replacement capabilities would require additional investment and time.
For American lawmakers, meanwhile, the immediate question remains unresolved.
The Pentagon has directed their concerns towards the military services responsible for aspects of satellite communications, rather than opening an independent inspector general investigation.
Whether those services can establish precisely who ordered the restrictions, what authority was exercised and whether contractual safeguards were observed will determine how much accountability emerges from the episode.
For Ukraine, the communications have been restored. The question of who could interrupt them, and under whose authority, remains unanswered.
