In 1956, Raytheon enters the EW arena with the launch of its Electromagnetics Systems division in Goleta, Calif.


Early EW System

Bob Fusfield, a 2001 Electronic Warfare Technology Hall of Fame inductee, examines an early electronic warfare system prototype.

First Pod-mounted Noise Jammer

In 1967, Raytheon’s ALQ-76 for the Marine Corps EA-6A was deployed in Vietnam reducing aircraft losses by degrading the effectiveness of enemy radar.


SLQ-32 Development

In 1977, Raytheon begins development of the first major shipboard electronic countermeasures (ECM) system using an RF phased array (Rotman lens) antenna system.


ALQ-184 Self-Protect ECM Pod

The ALQ-184 self-protect electronic countermeasures pod allows radar systems to jam simultaneous targets in multiple directions.


In 1984, Raytheon completed delivery of its 1,000th ALQ-128. This warning system continues to provide electronic support to the F-15.

ALE-50 Towed Decoy

In 1988, Raytheon began production of the ALE-50. The “Little Buddy” decoy has lured enemy missiles away from U.S. and Allied fighter pilots in Operation Allied Force, Desert Storm, and other theaters. To date, Raytheon has delivered more than 27,000 towed decoy systems.


In 1989, Raytheon completed upgrades to the TRQ-32(V)2, then the Army’s premier EW system.


SLQ-32(V)5 Sidekick

The “Sidekick” version of the SLQ-32(V)5 added jamming capabilities for smaller class ships.

Gallium Nitride

Raytheon begins testing gallium nitride, a heat transmitter, at its Integrated Air Defense Center. The material will later be vital to products such as the Patriot Air and Missile Defense System, AN/TPY-2 radar and Next Generation Jammer.


In 1997, Raytheon acquires Hughes Aircraft Company, Texas Instruments Inc. and E-Systems, gaining laser tracking expertise and full dimensional protection systems for overcoming electronic countermeasures.



In 2001, Raytheon was awarded a contract to build ALR-69A(V), a radar warning receiver that alerts pilots before missiles have a chance to lock onto a target.


In 2003, Raytheon’s ALR-67(V)3 radar warning receiver was proven in combat during Operation Iraqi Freedom.


In 2004, Raytheon won the contract for the ALQ-227, the communications jammer for the EA-18G.



In 2008, Raytheon’s integrated electronic warfare suite, the Advanced Countermeasures Electronic System (ACES) is competitively selected for Royal Moroccan Air Force F-16 aircraft.

Applied Signal Technology

In 2011, Raytheon acquires Applied Signal Technology, expanding its capability in communications and signals intelligence gathering to include products such as PEGASUS and TITAN B.


In 2012, Raytheon rolls out the first-ever highly autonomous, turbojet powered stand-in jammer: the ADM-160C MALD-J.


In 2013, Raytheon begins production on HARM (AGM-88B), a high speed anti-radiation missile to suppress or destroy surface-to-air missile radar and radar-directed air defense artillery systems, for the U.S. Air Force.


In 2013, Raytheon outfits the U.S. Army’s Grey Eagle with NERO, a remotely operated EW system that builds on the success of CEASAR, a communications electronic attack surveillance and reconnaissance system.

Next Generation Jammer

In 2013, Raytheon was selected by the U.S. Navy to conduct the Technology Development phase of its Next Generation Jammer program that will replace legacy ALQ-99 jamming pods on the Navy’s EA-18G Growler fleet.
