Boeing has completed upgrades on Saudi AWACS aircraft.
"Among the enhancements to improve radar capabilities and reduce repair time for the airborne surveillance fleet are systems that increase the original equipment's radar sensitivity and expand the range for tracking targets," according to a Boeing news release.
The Radar System Improvement Program upgrades comprise a new radar computer, a radar control maintenance panel and electrical and mechanical software and hardware, Boeing said.
"The modernized software, multiple radar nodes and overall enhanced operation make this is [sic] the most significant upgrade to the AWACS radar since it was developed in the 1970s," said Keith Burns, Boeing's Saudi AWACS program manager.
