Northrop Grumman Corporation (NYSE: NOC) recently completed its Critical Design Review (CDR) on a proliferated low-Earth orbit constellation of 16 missile tracking satellites for the Space Development Agency, clearing the way to begin production work on the space vehicles.
Candace Givens, vice president, overhead persistent infrared and geospatial systems, Northrop Grumman: “We are developing a more responsive, flexible and resilient space architecture to counter sophisticated threats. By passing this critical milestone on an accelerated timeline, we are closer to delivering critical missile defense and tracking technologies.”
Details on the PWSA:
Fourteen of the satellites for T1TRK will feature a wide field-of-view sensor, three optical communications terminals and a Ka-band payload for communications. Two satellites will feature a medium field-of-view infrared sensor to demonstrate a fire-control solution.
