The five-year award, worth a total of $32 million, includes spares, support equipment and technical services.
Exelis said it is supplying its AN/APY-11 radar, which is designed to support the service's maritime missions, including long-range surveillance, search and rescue, drug interdiction, counter-terrorism and maritime environmental support.
The radars will be integrated on the Coast Guard's HC-130J Super Hercules.
"This latest award is indicative of the value and versatility our radar offers the customer," said Pete Martin, director of programs, defense systems, for the Exelis electronic attack & release systems business. "As the U.S. Coast Guard's mission continues to evolve, our radar will enhance the reach and effectiveness of the HC-130J and its crews to protect our shores."
The AN/APY-11 is produced by Exelis in partnership with ELTA Systems Ltd. of Israel.
