Pentagon Inspector General Declines Probe of Starlink and Starshield Slowdowns in Ukraine

In late October, Ukraine’s Starshield system and commercial Starlink service experienced speed caps that limited terminal movement to roughly 160 km/h, hampering drone operations and early-warning communications. Nine senators—four Republicans and five Democrats, led by Sen. Thom Tillis and Sen. Jeanne Shaheen—sent a request on October 15 to Pentagon Inspector General Platte Moring for an investigation. On October 27, Moring’s office replied that the matters were “best addressed by the Department,” directing the senators to the Air Force and Space Force.

Starlink, operated by SpaceX, provides civilian internet worldwide. Starshield is a militarized variant for U.S. allies, including Ukraine, and has been critical since Russia’s 2022 invasion.

Halpern said the office “carefully considered the congressional request” and that the issues fall within the Pentagon’s purview, though the IG may revisit the decision if new information emerges. Shaheen called the refusal “concerning,” noting conflicting explanations from the administration and SpaceX. Tillis echoed the call for a transparent review, citing potential risks to U.S. personnel.
