The Pentagon’s inspector general has declined a bipartisan request from U.S. senators to investigate recent disruptions to Ukraine’s Starlink and Starshield services, instead directing lawmakers to take their concerns to the U.S. Air Force, according to the Associated Press, which reported on Oct. 28.
The Department of Defense Inspector General, an independent office responsible for auditing and investigating official conduct within the Pentagon, rebuffed the lawmakers’ request for a probe into reported disruptions to Starlink and Starshield, after SpaceX applied a speed cap to Ukraine’s military-grade Starshield service on Oct. 14, the Associated Press reported.
A group of five Democratic and four Republican senators sent an Oct. 15 letter to Inspector General Platte Moring, asking for an investigation into the disruptions. The letter sought answers on “whether any restrictions on Starlink or Starshield services were directed, authorized, or implemented by SpaceX, the Department of Defense, or other US government entities; whether such restrictions were consistent with applicable US government contracts, and what actions, if any, the Department of Defense took in response,” according to Ars Technica.
The watchdog’s response, received Oct. 27, told the lawmakers to direct their concerns to the U.S. Air Force instead. Sources familiar with the matter said the rebuff amounted to a refusal to investigate Elon Musk and Starlink, the Kyiv Independent reported.
Senator Jeanne Shaheen, a Democrat who signed the initial letter, told the AP the response was “concerning” and urged that because “the Trump Administration and SpaceX have provided conflicting accounts of what led to those disruptions,” there “must be an independent account and review.”
The disruption occurred on Oct. 14, when SpaceX abruptly imposed a speed cap on Starshield, the militarized version of its satellite internet service that Ukraine uses widely alongside commercial Starlink terminals. The cap limited connectivity to around 160 kilometers per hour (100 mph), affecting military drones that lost satellite connectivity above that speed, Ukraine said.
The move came amid heightened tensions between Kyiv and the White House. President Donald Trump had demanded that Ukraine halt attacks on Russian oil refineries and was making a deal with Russian President Vladimir Putin to import diesel from Russia. While no actor has taken responsibility for the decision to restrict Starlink, Musk reportedly approached Trump with the idea, according to the Telegraph, which cited four sources familiar with the matter. The Wall Street Journal reported that Trump ordered Musk on Oct. 21 to lift the restrictions, expressing frustration that the system’s speeds remained capped.
The speed cap was lifted after about 10 days. Another bipartisan group of senators sent a public letter to Musk on Oct. 23, reminding him that SpaceX is a publicly traded company with legal obligations to disclose information to shareholders.
Analysis
Why This Matters
- The Pentagon IG’s refusal leaves a key question unanswered: who decided to throttle Ukraine’s military communications and why.
- The episode exposes the influence a private contractor can have over U.S. military aid, with implications for accountability and the conduct of the war in Ukraine.
- Lawmakers have few remaining avenues for independent oversight; further action would likely require a subpoena or legislation.
Background
SpaceX’s Starlink has been a critical communications backbone for Ukraine since early in Russia’s full-scale invasion. The militarized Starshield variant provides encrypted services for military operations. In October 2026, SpaceX abruptly limited Starshield speeds, affecting Ukrainian drone operations. The restriction coincided with political pressure from the White House on Kyiv, and reports indicated Musk proposed the cap to President Trump. Trump later ordered the cap lifted after about 10 days.
Key Perspectives
- Bipartisan senators (five Democrats, four Republicans): Urgently requested an IG investigation into “whether actions or decisions by the Department of Defense or its contractors contributed to these dangerous circumstances” and called for an independent review given “conflicting accounts” from the Trump administration and SpaceX.
- Pentagon Inspector General: Declined to investigate, directing lawmakers to the U.S. Air Force instead, which sources interpreted as a refusal to examine Musk and SpaceX’s role.
What to Watch
- Whether the Air Force takes up the senators’ concerns or whether the probe is effectively closed.
- Next steps from Congress: lawmakers could hold hearings, issue subpoenas, or include oversight provisions in defense funding bills.
- Any future changes to Starlink/Starshield service terms for Ukraine, especially during periods of political tension between Washington and Kyiv.
