Summary points:

  • Boeing will provide 30 NGEAU B-kits and 22 spares for the EA-18G Growler Block II electronic warfare upgrade.
  • Work will upgrade sensors, jamming systems, and processing with modular B-kits complementing A-kit aircraft modifications.
  • Growler Block II features plug-and-play EW, multi-level security, and shared systems with the F/A-18E/F Block III jet fighter-bomber.

PATUXENT RIVER NAS, Md. – U.S. Navy airborne electronic warfare (EW) experts needed components necessary to upgrade the EA-18G Growler EW jet to the Growler Block II. They found a solution from the Boeing Co.

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., announced a $53.1 million order earlier this month to the Boeing Defense, Space & Security segment in St. Louis for 30 next-generation electronic attack unit (NGEAU) B-kits and 22 NGEAU B-kit Spares for the Growler Block II phase 1 upgrade.

NGEAU B-kits are modular hardware that complement the NGEAU A-kits, which include aircraft modifications for EW enhancements. B kits will help upgrade the Growler's sensors, processing, and jamming equipment to meet modern threats beyond what the Growler's baseline ALQ-99 jamming pods can do.

The Growler Block II will pursue more capable EW tactics via modular avionics upgrades in the field. It brings plug-and-play EW processing, multi-level security, and upgraded resource management.

Advanced cockpit system

The Growler Block II includes an advanced cockpit system and other internal improvements in common with the F/A-18E/F Block III jet fighter-bomber, and upgraded airborne electronic attack suite to enable the Growler to meet today's most advanced threats.

The plane carries two AIM-120 radar-guided air-to-air missiles three ALQ-99 airborne EW systems, two AGM-88 HARM anti-radar missiles; and two 480-gallon external fuel tanks.

On this order Boeing will do the work in Minneapolis; Linthicum, Md.; and St. Louis, and should be finished by December 2028. For more information contact Boeing Defense, Space & Security online at www.boeing.com/defense/ea-18g-growler, or Naval Air Systems Command at www.navair.navy.mil.
