Osprey Radar Upgrade

US Air Force Special Operations Command CV-22 Osprey tilt-rotor aircraft are being retrofitted with a low probability of intercept terrainfollowing and avoidance radar. The Raytheon APQ-187 Silent Knight radar will replace the current APQ- 186 as part of the Block 30 upgrade. Some special operations helicopters have previously been fitted with the new radar, which is scheduled to be installed on all CV-22s by mid-2019.
