Northrop Grumman received a $298 million contract to develop a jam-resistant military satellite to supplement and eventually replace the existing Advanced Extremely High Frequency (AEHF) satellites made by Lockheed Martin.

The Space and Missile Systems Center announced the contract award Sept. 16 for the Evolved Strategic Satellite Communications program, known as Evolved Strategic Satcom. The satellite has to be completed by May 2025.

The ESS program continues the strategic satcom mission of the AEHF constellation. This includes providing survivable, global, secure, protected, and jam-resistant communications for high-priority military operations and national command authorities.
