Elon Musk’s biographer, Walter Isaacson, has taken to social media to clarify a significant detail from his upcoming book on Musk. Isaacson previously described how Musk intervened in a Ukrainian attack on Russian warships by instructing his engineers to turn off coverage within 100 kilometers of the Crimean coast. This action resulted in Ukrainian drone subs losing connectivity and washing ashore harmlessly. However, Isaacson now clarifies that Musk did not enable coverage because he believed it would cause a major war. Isaacson adds that Musk reaffirmed the policy that Starlink was not meant to be involved in wars. Ukraine reportedly received over 120,000 Starlink terminals since being invaded by Russia last February. These terminals communicate with SpaceX’s satellites to provide online connectivity. The full extent of the Ukrainian payment for these services is unclear. Isaacson also clears up the timeline of the policy, stating that Musk had implemented it before the night of the Ukrainian attempted sneak attack. Isaacson’s clarifications came after a senior aide to Ukraine President Volodymyr Zelenskyy accused Musk of “committing evil” by allegedly thwarting the drone attack on the Russian fleet. Russia illegally annexed Crimea from Ukraine in 2014, and tensions between the two countries remain high. Representatives for SpaceX have not commented on the matter.
