Lockheed Martin has fielded an electronic warfare fixed-wing variant, the AN/ALQ-217, on the U.S. Navy’s E-2C aircraft and are currently producing a variant for the E-2D. Additionally, 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. 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 help detect and defeat future threats, Lockheed Martin is miniaturizing the digital receiver ESM systems for fixed, rotary wing, and unmanned aerial system application. Lockheed Martin has already developed several Group 1-5 UAS platforms dedicated to providing ESM and close-in jamming support.
