SpaceX has won an $150.45 million contract from the Pentagon’s Space Development Agency (SDA) to launch up to 28 satellites.

SpaceX will conduct the first of two launches from Vandenberg Air Force Base in California in September 2022. SDA wants the entire 28-satellite constellation in orbit by March 31, 2023.

SDA’s constellation will be composed of small and medium size spacecraft, with 20 data-relay and eight missile-warning satellites.

The satellites will be divided into two planes of 14 spacecraft each deployed in 950 km high near-polar orbits.
