New Satellites Will Be A Big Step In The Pentagon’s Plan To Link Everything

A new “transport layer” constellation will help distribute tactical data — but won’t have defenses against anti-satellite weapons.

The U.S. military’s push to link every object on the battlefield leaped forward Thursday with the release of a request for proposals to build 20 tactical-communications satellites by 2022.

The year-old Space Development Agency, or SDA, hosted an industry day to tell satellite makers about its plans for “transport layer”: essentially, orbiting communications nodes to transfer data related to intelligence, battle management, navigation and timing; and more.

The transport layer won’t replace the military’s existing communications satellites or the commercial ones whose services it rents, SDA director Derek Tournear told reporters. Instead the new layer will focus on “tactical data points that need to be given to a weapon system.” It will ferry very-time-sensitive data from drones, satellites in low Earth orbit, and other sensors. Pentagon officials received $25 million to develop and flight-test the satellites in the 2020 budget, and have asked for just under $100 million in 2021, said Tournear.
