The Pentagon’s Space Development Agency (SDA) has awarded contracts worth approximately $1.3 billion to York Space and Northrop Grumman to construct communications satellites. The goal is to create a network called the Proliferated Warfighter Space Architecture (PWSA), with the companies tasked with building 100 satellites for the “Alpha” variant prototypes in the “Tranche 2 Transport Layer” constellation (T2TL-Alpha). These satellites will provide encrypted communications.
