Known for a high-profile incident in 2001
Propelled into the spotlight after the Hainan Island incident
The EP-3E Aries II gained international attention in 2001 after a mid-air collision with a Chinese fighter jet over the South China Sea. This event, often referred to as the Hainan Island incident, brought the aircraft into the spotlight and showcased the importance and sensitivity of its missions.
As described in Air & Space Forces Magazine, over the South China Sea Islands – one of the most strategically sensitive areas in the world – a Chinese J-8 made two close passes with an EP-3 that was nearing the end of its six-hour electronic signals intelligence (ELINT) mission.
On the third pass, both aircraft collided, sending the EP-3 into a dive. The crew was forced to make an emergency landing, and the incident highlighted the risks associated with its intelligence-gathering operations in disputed regions.
