While Starlink claims to be a civilian program that provides high-speed Internet services, it has a strong military background, as well evidenced by the fact that some of the launch sites are built within the Vandenberg Air Force Base and the encrypted interconnection between the satellites and Air Force fighters has been included into their technical verification tests.
As a matter of fact, Starlink has cooperated with American military many times. In 2019, SpaceX received funds from the US Air Force to test how well Starlink satellites can connect with military aircraft under encryption; in May 2020, the US Army signed an agreement with SpaceX on the use of Starlink's broadband to transmit data across military networks; in October 2020, SpaceX won a USD 150-million contract to develop military-use satellites; in March 2021, it announced its plan to work with the US Air Force to further test the Starlink Internet.
When completed, Starlink satellites can be mounted with reconnaissance, navigation and meteorological devices to further enhance the US military's combat capability in such areas as reconnaissance remote sensing, communications relay, navigation and positioning, attack and collision, and space sheltering.
Clearly, the military applications of the Starlink program will give the US military a head-start on the future battlefield and become an "accomplice" for the US to continue to dominate the space.
