Northrop Grumman announced the delivery of 21 satellites to Vandenberg Space Force Base for the U.S. Space Force's Transport Layer (T1TL) initiative. This layer will consist of 126 low-Earth orbit satellites aimed at enhancing secure military communications and missile deterrence. The Transport Layer is a key component of the Proliferated Warfighter Space Architecture (PWSA). The delivery is part of a larger effort that includes 42 satellites each from Northrop Grumman, York Space Systems, and Lockheed Martin. The program is reportedly over a year behind schedule due to supply chain issues affecting Optical Communication Terminals. The next launch of T1TL satellites is expected in early October 2026, with all satellites projected to be operational within six to eight months.
