Northrop Grumman Corp. in Rolling Meadows, IL recently received a 5-year $457.1 million firm-fixed-price contract for its APR-39A/B/C Radar Signal Detection Set (RSDS) including upgrade kits; and repair, integration, interim software support and field support. Work is to be performed in Rolling Meadows, IL, with an estimated completion date of Dec 31/14. One bid was solicited with one bid received by U.S. Army CECOM at Aberdeen Proving Ground, MD (W15P7T-10-D-R802).

APR-39s are used on an array of US Army and Navy helicopters and fixed wing aircraft, and serve to warn pilots when they’re targeted by radar. Platforms with the APR-39 range from C-130 and RC-7s, to attack helicopters like the AH-1 and AH-64, to transport rotaries from the MV-22 and CH-47 to MH-60S and even US Presidential helicopters.

The AN/APR-39Av2 is a basic threat warning system, which acts as a control for a survivability suite that includes a laser warning receiver and an infrared missile warner. The AN/APR-39Bv2 also acts as a full electronic warfare management system, serving as the heart of Northrop Grumman’s Suite of Integrated Sensors and Countermeasures (SISCM). Customers can add onboard sensors as SISCM input, or upgrade existing components. It will automatically detect and identify threat type, bearing and danger levels, then alert the crew to each threat with a graphical symbol in the cockpit multifunction display (MFD) or video display, accompanied by synthetic speech audio threat warnings. It also records what it finds for later analysis, if its aircraft returns. Northrop Grumman release
