On March 17, Gen. Mark A. Milley, the chairman of the Joint Chiefs of Staff, and Gen. Valeriy Zaluzhnyi, the leader of Ukraine’s Armed Forces, dialed into a call to discuss Russia’s invasion of Ukraine. Over the secure line, the two military leaders conferred on air defense systems, real-time battlefield assessments and shared intelligence on Russia’s military losses.
They also talked about Elon Musk.
General Zaluzhnyi raised the topic of Starlink, the satellite internet technology made by Mr. Musk’s rocket company, SpaceX, three people with knowledge of the conversation said. Ukraine’s battlefield decisions depended on the continued use of Starlink for communications, General Zaluzhnyi said, and his country wanted to ensure access and discuss how to cover the cost of the service.
General Zaluzhnyi also asked if the United States had an assessment of Mr. Musk, who has sprawling business interests and murky politics — to which American officials gave no answer.
Mr. Musk, who leads SpaceX, Tesla and Twitter, has become the most dominant player in space as he has steadily amassed power over the strategically significant field of satellite internet. Yet faced with little regulation and oversight, his erratic and personality-driven style has increasingly worried militaries and political leaders around the world, with the tech billionaire sometimes wielding his authority in unpredictable ways.
