L-3 Aviation Products (AP) announced today that Sikorsky Aircraft Corporation has selected the GH-3001™ Electronic Standby Instrument System (ESIS), Stormscope® WX-500 Lightning Detection System and PS-855 Emergency Power Supply (EPS) for its H-60 and S-70i™ helicopter platforms. This follow-on award is a five-year contract that spans from 2013 through 2017.

The Sikorsky H-60 and S-70i aircraft are flown by more than 25 countries, with the U.S. Army and Navy operating the bulk of them.

"This award represents the single largest order we've received from an OEM for our GH, Stormscope and Power Supply products," said Ralph DeMarco, vice president of sales and marketing for L-3 Aviation Products. "With the inclusion of these very capable avionics, Sikorsky's line of military rotorcraft continues to set the benchmark for the most modern and capable helicopters available."

Designed with military platforms in mind, the night vision goggle (NVG)-compatible GH-3001 ESIS provides accurate attitude, altitude, airspeed and heading cues in a compact unit that has been certified to higher EMI levels. Customized tape readouts allow the addition of a Vertical Speed Indicator (VSI).

The WX-500 Stormscope is a passive system that was developed specifically to detect and map thunderstorms by analyzing the radiated signals of electrical discharges from storm cells. By detecting the electrical activity, Stormscope provides an accurate view of areas that are the most dangerous portions of a thunderstorm.

The PS-855 EPS supplies power to critical avionics in the event of an emergency and produces additional power output at 24 VDC to run other emergency equipment without interruption. The batteries are capable of withstanding severe performance requirements, including thermal shock and high charge and discharge rates.
