In June 1968 U.S. and Australian forces near the Demilitarized Zone in Vietnam reported mysterious contacts they took for North Vietnamese helicopters. During the confusion, U.S. Air Force jets mistakenly attacked the Australian destroyer HMAS Hobart, killing two sailors. In 1973 the Air Force's chief of staff publicly called the original sightings "UFO" sightings.[1][2]

In the early hours of 17 June 1968 Hobart was on surveillance near Tiger Island, following reports of North Vietnamese helicopter activity in the area. At 3:09 a.m. its radar detected an aircraft without an active identification transponder, which made three passes: on the first it fired one missile, on the second two, and the third was broken off when the ship's forward gun fired. Two sailors were killed and eight wounded. Debris showed the missiles were American, and the cruiser USS Boston had also been hit by a missile from another aircraft.[1]

A U.S. Navy inquiry, with three Royal Australian Navy advisers, examined a series of firing incidents from 15 to 17 June. It found that U.S. patrol boats and a Coast Guard cutter had first come under attack from aircraft believed to be friendly, and that one patrol boat had been sunk; Seventh Air Force F-4 Phantoms sent to respond could not distinguish ships from hovering helicopters on radar and opened fire on Hobart, Boston and the destroyer Edson.[1]

In October 1973 General George Brown, who had commanded the Seventh Air Force in Vietnam and was then Air Force chief of staff, told reporters that early in the summer of 1968 a series of sightings near the Demilitarized Zone, which he said were called UFO sightings at the time, had set off "quite a battle", with an Australian destroyer taking a hit. He did not say what the objects were.[2][3]

According to the testimony, a former analyst said in 2014 that some of the "enemy helicopters" were in fact UAP. The friendly-fire incident is well documented, but the cause of the original radar contacts has never been officially explained; some analysts suggest radar errors or misidentification in a chaotic period of combat.[1][4]
