What is the use of military satellites?

Military satellites are mainly used for reconnaissance, communication, navigation and early warning. Many countries regard military satellites as an important part of national defense competition, allowing them to show their talents in modern wars. In peacetime, these military satellites were transformed into civilian use to serve economic construction.

The development trend of military satellites mainly lies in improving the survivability and anti-jamming ability of satellites, realizing all-weather and all-time coverage of the earth and real-time transmission of information, prolonging the working life and expanding military uses.
