La Joya (Arequipa) UFO Encounter, 1980

Background

La Joya is a Peruvian Air Force base near Arequipa, in the south of the country. The base hosted Sukhoi Su-22 fighter-bombers in 1980, and the event became one of the best-known military UFO stories in South America. Almost everything publicly known about it comes from one pilot, Col. Óscar Santa María Huerta, who repeated the story in Peruvian press, on television, and in Washington. Peru's own Air Force has not published an official report on the episode.

The encounter

According to Epoch Times reporting on Huerta's 2013 testimony, the scramble began around 7:15 a.m. on 11 April 1980, after a stationary, ball-shaped object was seen about 1,800 feet up and roughly three miles from the base. Base officers reportedly worried that the object was conducting surveillance over sensitive material. Huerta said he fired around sixty 30mm rounds with no visible effect, that the object seemed to absorb them, and that it never retaliated. He described a chase of roughly 22 minutes and about 50 miles, during which the object stayed level with his jet, and said he climbed to around 63,000 feet before returning low on fuel.

La República, which reported the story in 2008, gives a different set of numbers: 64 bursts, a chase of about 20 minutes, and a climb to roughly 19,000 meters. That figure exceeds the Su-22's stated 18,300-meter ceiling, and the article says the aircraft then lost power and forced a return. The pilot's description of the object was consistent across retellings: a dome-shaped craft with no wings, windows, antennas or visible exhaust. Diario Correo (2023) repeats the 64-round figure and adds that the object climbed away and then stopped abruptly, forcing the pilot to turn to avoid a collision.

Official records

The strongest documentary link is a Defense Intelligence Agency intelligence information report, IIR 6 876 0146 80, which describes a Peruvian Air Force pilot trying to intercept a round object hovering near the airfield, unable to damage it, and watching it outrun his aircraft. The copy circulating through the UFOscans declassified collection is marked CONFIDENTIAL and dated 27 July 1987 on the page, though its reference number points to 1980. The page gives no release authority, and its summary is machine-generated and flagged for checking, so the original PDF should be consulted before relying on the date. Huerta also says he submitted a copy of a U.S. Defense Department message at the 2013 National Press Club hearing; the La República article describes a similar document circulated to the CIA, State Department and NSA.

Local radar reportedly did not register the object, according to base personnel quoted by La República. No public FAP statement on the event has been located in the sources reviewed.

Assessment

The case is contested. Its supporters point to a named, decorated-era pilot who has repeated a consistent core story for over a decade; to a DIA report that corroborates an intercept attempt on a hovering object near La Joya; and to the military setting, which makes it more than a civilian sighting. Skeptics note that the surviving accounts disagree on the date (11 April, 9 May, or simply May 1980), the duration (20 to 22 minutes, or nearly an hour), the number of rounds, and the altitude. Nearly all the detailed claims, including the 63,000-foot climb, the ground witness count of about 1,800 reported by UFO websites, and the object's supposed supersonic start-from-standstill, come from the pilot or from UFO-focused outlets. An intercept report on its own shows that a pilot reported something; it does not show what that something was, and no physical evidence has been published.

The case is best understood as a documented military report of an unidentified object, with its most dramatic details resting on one man's testimony.
