The 10 satellites, which will be lofted on a reusable SpaceX Falcon 9 from Vandenberg SFB to low Earth orbit (LEO), are the first batch of the Tranche 0 constellation, building blocks of America's resilient space strategy.
The bulk of SDA's FY24 request, some $4.1 billion, is in research, development, test and evaluation aimed at getting the first iterations of its planned satellites for both data relay, called the Transport Layer, and missile warning and tracking, called the Tracking Layer, into orbit.
The name change for SDA's seven-layer network of satellite and ground systems was approved by both Air Force Secretary Frank Kendall and space acquisition czar Frank Calvelli, and is designed to better reflect the network's actual mission, SDA Director Derek Tournear told Breaking Defense.
