Military missions begin long before aircraft enter hostile airspace. Both sides are constantly using the electromagnetic spectrum to sense, track and understand what is happening across the battlespace.
The side that controls this invisible environment gains a critical advantage.
Today, one of the most important parts of that environment is the low frequency spectrum. Low band electronic warfare has become a mission critical need, because it helps protect United States and allied forces from being detected while performing combat air patrols.
Why Low Band Matters
Low frequency radar systems challenge the stealth characteristics on which modern aircraft depend, because their radar waves are more likely to detect platforms designed to evade high-frequency detection.
“Because of this, low band systems often form the backbone of an enemy’s early warning network,” said Lauren Barnes, President, Spectrum Superiority, L3Harris. “Disrupting low frequency radars early in an operation can blind the adversary long enough for friendly aircraft to move in safely and controlling the low frequency layer is key to defeating an adversary’s early warning systems and staying ahead of rapidly evolving threats.”
A Growing Threat
Adversaries of the U.S. and coalition forces are improving these long range, low frequency radar networks. Their air defense systems now cover larger areas and can detect incoming aircraft sooner. This pushes U.S. naval strike groups to operate from much farther away, keeping military personnel safer.
The U.S. Navy’s Next Generation Jammer – Low Band (NGJ LB) is designed specifically for this mission. It extends airborne electronic attack deeper into the low frequency range, giving naval aviators the tools they need to counter long range detection systems.
“EA 18G Growlers equipped with NGJ LB use advanced jamming capabilities to overwhelm and blind enemy low frequency radars,” said Barnes. “Controlling the electromagnetic spectrum makes it possible to jam air defense and ground communication systems at longer ranges.”
A System Built to Win the Spectrum
NGJ LB is built on a software defined architecture, meaning it can be rapidly updated to counter new threats without costly hardware upgrades. This gives the Navy a more flexible and cost effective way to stay ahead in a fast changing environment.
L3Harris provides the software backbone that powers NGJ LB, delivering rapid development and seamless integration across the fleet.
Controlling the low band spectrum isn’t just another capability. Low-band aerial electronic attack is the foundation that protects every aircraft, every mission and every service member in the battlespace. When forces can operate without being detected, they control the pace of the fight.
And, in modern warfare, controlling the spectrum often means controlling the outcome.
