Musk, CEO of SpaceX, launched an attack on Amazon on social media on Tuesday as SpaceX is trying to persuade officials of the Federal Communications Commission to allow SpaceX to move some of its Starlink satellites lower than originally planned.
Amazon, along with other companies, has challenged SpaceX's request on the grounds that the change would interfere with other satellites.
"There's no need for [Amazon] to get in the way of Starlink right now, because it's still a few years before Amazon's satellite system is really operational," Musk said on social media
Later last week, SpaceX director David Goldman made the comments after talking to FCC officials about the company's proposal to move some Starlink satellites to lower altitudes.
Goldman stressed that Amazon's representatives had "held 30 meetings against SpaceX" but "did not hold any meetings to authorize their own systems," saying Amazon was trying to "stifle competition.".
Amazon did not immediately respond to media requests for comment on Musk's statement.
Meanwhile, Amazon has been developing its own satellite Internet program called project Kuiper. Project Kuiper plans to launch 3236 Internet satellites into low earth orbit, which will compete with Starlink. Although Amazon reached an early milestone in December of key hardware for the antennas it needs to connect to the network, it has yet to start producing or launching satellites.
The FCC approved Amazon's Kuiper proposal in July last year, and the company said it would invest more than $10 billion in construction.
