Elon Musk urged by House China committee to open SpaceX Starshield internet to U.S. troops stationed in Taiwan.

The House Select Committee on the Chinese Communist Party has reached out to Elon Musk, CEO of SpaceX and Tesla, demanding access to SpaceX’s Starshield satellite communication network for U.S. troops stationed in Taiwan. The committee, chaired by Rep. Mike Gallagher, alleges that SpaceX’s failure to provide this access may breach its Pentagon contract, which mandates “global access” to Starshield technology.

This letter, obtained by CNBC and first reported by Forbes, expressed concerns that SpaceX might be withholding broadband internet services in the Taiwan region, potentially violating contractual obligations with the U.S. government. The Pentagon had previously awarded SpaceX a one-year contract for Starshield in September, following the commissioning of SpaceX’s Starlink network for Ukraine’s conflict with Russia.

A spokesperson for the Office of the Secretary of Defense declined to comment on the correspondence at this time.

The committee’s letter follows a visit to Taiwan led by Rep. Gallagher, during which he and other lawmakers met with Taiwanese officials including President Tsai Ing-wen and President-Elect Lai Ching-te. It was during this visit that they discovered U.S. troops in Taiwan were unable to utilize Starshield despite the Pentagon’s requirement for global access.

The letter requests a briefing from Musk on SpaceX’s Taiwan operations by March 8.

Taiwan, operating independently from China since the 1949 civil war, remains a point of contention, with China claiming sovereignty over the island. The letter highlights the importance of robust communication networks for U.S. military personnel in the Indo-Pacific region, especially in light of potential aggression from the Chinese Communist Party.

The success of Tesla, in particular, relies on favorable business relations with China. Elon Musk has previously faced criticism from Taiwanese officials for comments seeming to support China’s stance on Taiwan’s reunification.

SpaceX and Musk have yet to respond to requests for comment on the letter.
