The AN/ALQ-211 enables pilots to evade and defeat modern radar-detected air defense threats
L3Harris develops and fields EW systems that provide pilots and aircrews with the ability to see first, understand first and act first
EW is increasingly important as part of U.S. national security strategies
The AN/ALQ-211 radar warning jammer and receiver provides critical warfighter capability to detect, disrupt, deny and degrade threats throughout the battlespace.
The L3Harris SIRFC solution or AN/ALQ-211 is modular and scalable to rotary-, fixed-wing, pods or unmanned aerial vehicle (UAV) platforms.
As the sole provider of radio frequency (RF) countermeasures for U.S. DoD rotorcraft, L3Harris is assisting today’s aircrews as they face rapidly changing EW.

Historical threat engagements are recorded at the Tactical Operations Center (TOC) for future missions
Threats are priortized and handled based on best available countermeasures
Disadvantaged (non-ASE) platforms make use of advanced ASE on other aircraft
Platforms share available ASE across the localized network
Airborne platforms see each other's location on digital maps in real-time
Wingman network EW concept of operations (CONOPS):
L3Harris’ network EW concept of operations (NEWC)’s advanced capabilities provide full-dimensional battlespace awareness and improved aircraft survivability against near-peer asymmetric threats.
