Airborne Electronic Warfare

Lockheed Martin’s knowledge of airborne protection extends well beyond platform development. Lockheed Martin has fielded more than 3,000 airborne electronic warfare systems over the last 45 years, including electronic support measure (ESM), electronic attack (EA), radar warning receiver (RWR), electronic intelligence, communications intelligence, and anti-jam GPS products. These passive sensor systems protect the warfighter by functioning as the “ears” of advanced tactical aircraft, identifying and locating sources of radio frequency emission and providing a full range of electronic support operations.

To date, Lockheed Martin continues production of the AN/ALQ-210 for the U.S. Navy and international MH-60R and the AN/ALQ-217 on the U.S. Navy’s E-2C/D aircraft. Lockheed Martin is slated to upgrade the ALQ-217 with a digital receiver and enhanced capabilities starting in mid-2018. Lockheed Martin has modernized the targeting ESM system on the U.S. Army and international Apache AH-64D/E aircraft with the digital receiver based Modernized Radar Frequency Interferometer (MRFI) known as the AN/APR-48B.  Lockheed Martin extends this digital receiver product line with its newest system, the APR-52 Digital RWR, on the USAF Combat Rescue Helicopter.  

To help detect and defeat future threats, Lockheed Martin continues to advance EW systems for fixed, rotary wing, and unmanned aerial system application.

AN/ALQ-210 – ESM - MH-60R

The multi-mission AN/ALQ-210 Electronic Support Measures (ESM) and concurrent RWR system is your solution to the complex and dense electronic battlefield, providing proven situational awareness and simultaneous threat warning with ELINT quality measurement accuracy.  The system is currently in full rate production for the U.S. Navy and international customers.

AN/ALQ-217 – ESM - E-2C/D

The AN/ALQ-217 ESM system functions as the highly sophisticated ears of advanced tactical aircraft and is currently installed on the U.S. and international E-2C and E-2D Advanced Hawkeye and P-3C type aircraft. The system protects the warfighter by identifying and locating sources of radio frequency (RF) emission providing a full range of ESM operation with ELINT quality measurement accuracy. The system is currently in full rate production for the U.S. Navy and international customers. A major upgrade of the ALQ-217 is planned for mid-2018 to include a digital receiver and other enhanced capabilities.

AN/APR-48B – Targeting ESM - Apache AH-64D/E

The AN/APR-48B Modernized Radar Frequency Interferometer (MRFI) is installed on the AH-64E Apache Guardian helicopter and backwards compatible to AH-64D Apache Longbow. Its digital receiver-based signal intercept, positive identification, fast response time and precision Direction Finding (DF) capabilities establish it as both an accurate targeting system and a superior Radar Warning Receiver (RWR) for helicopters.

AN/APR-52 – Digital RWR - Combat Rescue Helicopter (CRH) HH-60W

The high performance AN/APR-52 RWR provides the critical protection necessary for CRH to conduct its vastly challenging search and rescue mission set.  The APR-52 provides long range detection of advanced threats to ensure the platform’s survival in the harshest electromagnetic environments.

GPS Spatial Temporal Anti-Jam Receiver (GSTAR)

GSTAR is a fully digital system providing the strongest protection against adversarial jammers and spoofers for all types of platforms. The high-end beam-steering capability allows the host platform to survive the harshest of contested environments. GSTAR can be configured as a nulling only solution for compatibility with existing GPS Receivers with the inherent growth to beam-steering without replacement of the GSTAR or the antenna.
