Navy awards Next Generation Jammer Low Band contracts

NAVAL AIR SYSTEMS COMMAND, PATUXENT RIVER, Md. – The U.S. Navy awarded Demonstration of Existing Technologies (DET) contracts Oct. 25 valued at approximately $36 million each to L3 Technologies Communications Systems West and Northrop Grumman Corp. Mission Systems in support of the Next Generation Jammer Low Band (NGJ-LB) capability.

The Airborne Electronic Attack (AEA) Systems and EA-6B Program Office (PMA-234) headquartered here manages the NGJ-LB program.


Next Generation Jammer Increment 1, an external jamming pod, will replace the AN/ALQ-99 tactical jamming system currently integrated on the EA-18G GROWLER® aircraft. It will address advanced and emerging threats alike, as well as the growing number of threats.

NGJ-LB is an external jamming pod that is part of a larger NGJ weapon system that will augment and, ultimately, replace the aging ALQ-99 Tactical Jamming System currently in use on EA-18G Growler aircraft.

“NGJ-LB is a critical piece of the overall NGJ system in that it focuses on the denial, degradation, deception and disruption of our adversaries’ abilities to gain an advantage in that portion of the electromagnetic spectrum,” said Capt. Michael Orr, PMA-234 program manager. “It delivers to the warfighter significant improvements in power, advanced jamming techniques, and jamming effectiveness over the legacy ALQ-99 system.”


The ALE-43(V)4 is the carrier-based (CV) and U.S. Marine Corps expeditionary dispenser for wide area chaff.

Each DET contract has a 20-month period of performance, during which the NGJ-LB team will assess the technological maturity of the industry partners’ existing technologies in order to inform future NGJ-LB capability development, as well as define the NGJ-LB acquisition strategy.


The ALQ-99 Tactical Jamming System is integrated on both the EA-6B and EA-18G aircraft and is designed to provide vital jamming capability against radar and communications targets in the Suppression of Enemy Air Defense (SEAD) role.

PMA-234 is responsible for acquiring, delivering and sustaining AEA systems and EA-6B Prowler aircraft, providing combatant commanders with capabilities that enable mission success.

The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.

To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at davidhiggins@southernmarylandchronicle.com

Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
