Italian Air Force Eurofighter UAP Pursuit 2009

On July 23, 2009, NATO air surveillance over the Adriatic detected an unidentified contact at 45,000 feet performing maneuvers inconsistent with any known aircraft. Italian Air Force Eurofighter Typhoons — among the most capable fighters in European service — were scrambled from a Mediterranean base. The Typhoon's Captor mechanically-scanned radar achieved a brief lock-on before the contact executed an instantaneous 90-degree turn and accelerated to a speed beyond the Typhoon's radar acquisition range. The departure was vertical as well as horizontal. Decimomannu radar in Sardinia tracked the contact briefly. A NATO Airborne Warning and Control System aircraft in the area confirmed the radar track. Italy's Air Force filed a classified incident report. The case is significant because it demonstrates the same radar defeat and 90-degree turn capabilities documented in Vietnam-era and Cold War encounters being observed against a fourth-generation Eurofighter with AESA-equivalent radar — suggesting consistent performance characteristics across decades of encounters with different radar technologies.
