Six of 36 of South Korea's AH-64E helicopters, purchased through the US Foreign and Military Sales, were equipped with Lockheed Martin's Longbow fire control radar, however, during air assault operational tests between last October to November the radar failed to detect the number of enemy targets, Defense News reported on Thursday citing South Korea's Defense Acquisition Program Administration.
The radar, the report added, mistakenly recognized four designated targets for 101 targets and 18 for 9 when tested in mountainous regions. The radar also failed to detect any target during a test over water, the report said.
