U.S. Space Force Conducts System Level CDR for Missile Warning Satellite

The U.S. Space Force and Lockheed Martin conducted the system level Critical Design Review (CDR) for the Next Generation Overhead Persistent Infrared Geosynchronous Earth Orbit (NGG) Block 0 space program.

This marks another significant step toward the first NGG satellite launch in 2025.

NGG is the Space Force’s new, advanced space-based missile warning system that incorporates improved warning capabilities as well as enhanced resiliency and cyber hardening. Dubbed by the U.S. Department of Defense as a “Go Fast” acquisition program – meaning a quicker delivery timeline – NGG will provide early warning for the defensive “kill chain” that protects our nation and armed forces from missile threats. The new system responds to challenges from rival nations that increasingly seek to erode space advantages held by the United States.

The NGG Block 0 program held the system level CDR on October 28, maintaining the program’s accelerated pace. The CDR specifically addressed the integration between the space and ground segments in addition to the integration of the Next Generation Interim Operations Ground System with the legacy Missile Warning system, enabling the enhanced missile warning capabilities following launch.

Under the NGG Block 0 program, Lockheed Martin in partnership with the U.S. Space Force is developing and building three satellites that provide improved missile warning capabilities and are even more resilient against emerging threats. Carrying new advanced infrared sensors that can detect dimmer and faster targets, the first satellite is racing to launch in 2025.

The system level CDR is the latest milestone the program has met since the 2018 contract award. Earlier this year, under Lockheed Martin’s prime contractor leadership, NGG completed CDRs for two mission payloads being competitively developed by subcontractor teams Raytheon and a Northrop Grumman/Ball team. One of the two mission payloads will each fly on the first two NGG space vehicles. The team completed a separate space vehicle CDR, which aggregated numerous subsystem and payload reviews, and locked in the satellite’s technical baseline.

“A space program of this size, which includes developing two entirely new missile warning payloads, has never moved this fast,” said Joseph Rickers, Lockheed Martin vice president and program manager for NGG Block 0. “The program is on schedule due to using proven technologies and risk mitigation tools like subsystem prototypes for early design verification and interface integration to ensure we remain on track.”

Lockheed Martin’s NGG program is embracing digital transformation as a way to deliver next generation capabilities quicker and faster. NGG is being built on LM 2100 Combat Bus. This modernized space vehicle provides enhanced spacecraft power, propulsion and electronics, as well as common components and procedures to streamline manufacturing.
