REDSTONE ARSENAL, Ala. – U.S. Army combat helicopter designers a company to upgrade and redesign software for an electronic warfare (EW) system that enables the AH-64E Apache Guardian attack helicopter to detect and identify enemy radar threats. They found their solution from Lockheed Martin Corp.

Officials of the Army Contracting Command at Redstone Arsenal, Ala., announced a $13 million order last month to the Lockheed Martin Rotary and Mission Systems segment in Owego, N.Y., to upgrade and redesign software for the Apache Modernized-Radar Frequency Interferometer (MRFI).

The MRFI identifies intelligence, surveillance, and reconnaissance (ISR) emitters, and helps the AH-64E pilot to detect and engage an enemy radar threat long before the aircraft becomes vulnerable.

The MRFI avionics system quickly detects, identifies, and locates enemy radar, and then ranks these hostile radars in order of priority for subsequent ground attack.

The MRFI is part of the AH-64E's digital receiver-based AN/APR-48B system, which performs target acquisition and cueing for the helicopter's fire-control radar system.

It also can deliver warning of radar directed antiaircraft threats and serve as the controller for an integrated aircraft survivability equipment. The system provides high sensitivity and precision angle of attack in a lightweight modular configuration.

The AN/APR-48B system primarily operates on a dual-redundant MIL-STD-1553B databus. Other commercial I/O interfaces available for future growth include Gigabit Ethernet, RS-232, and RS-422.

On this contract Lockheed Martin will do the work in Owego, N.Y., and should be finished by October 2023.
