The Naval Air Warfare Center Weapons Division at Point Mugu, California intends to award a sole source contract to Northrop Grumman Systems Corporation for full life-cycle engineering, technical, and programmatic services supporting the EA-18G Growler Airborne Electronic Attack subsystem. The work includes developing, delivering, and sustaining continuous capability upgrades through new hardware, software, firmware, and mission planning systems. Northrop Grumman is uniquely qualified as the sole designer, developer, and integrator of the EA-18G and EA-6B systems, holding data rights to 31 critical algorithms and all tactical software expertise. Performance requires a Top Secret facility clearance, and the contract is not a competitive solicitation, though capability statements from other firms will be considered. No budget amount or submission timeline is specified in this notice.
