Advanced electronic warfare countermeasures for U.S. Army rotorcraft will get their first in-flight shakedowns this summer aboard this next-generation AH-64D Apache Longbow multi-role combat helicopter. The Boeing Company in Mesa, Ariz., has integrated the lightweight AN/ALQ-211 Suite of Integrated Radio-Frequency Countermeasures -- or SIRFC -- equipment into an Apache Longbow prototype aircraft for flight test and evaluations. Boeing pilots and support teams will conduct the tests at the U.S. Navy's electronic warfare range at China Lake, Calif.
