Arequipa
A Peruvian Air Force Su-22 fires on a balloon-shaped object and cannot bring it down
Personnel at a Peruvian air base observed a stationary balloon-shaped object at dawn. A Su-22 was scrambled and, by the pilot's account, fired a cannon burst that had no effect, after which the object climbed away from the pursuing aircraft.
Official position
No published official determination. The account comes from the pilot, later corroborated by other base personnel.
Alternative hypotheses
- A high-altitude balloon, which would explain the shape, the station-keeping and the pilot's inability to reach it — the leading explanation.
- A misjudged engagement against a target far more distant than assumed.
- A genuine unidentified object.
Why a non-US military case matters here
Arequipa is one of very few documented instances anywhere of a military aircraft actually firing on a UAP. Whatever it was, an air force treated it as a potential intruder over a sensitive base and committed ordnance.
That is a fact about state behaviour, and it is why the case belongs in a global corpus that is otherwise heavily weighted toward the United States.
The balloon explanation is strong, and worth taking seriously
A large high-altitude balloon accounts for a great deal here: the shape, the apparent hovering, the inability of a fast jet to engage it effectively, and the eventual climb out of reach as the aircraft runs out of performance at altitude.
Cannon rounds fired at a balloon at long range would very plausibly do nothing visible.
What is missing
Everything instrumental. No radar record has been published, no gun camera footage, no unit documentation. The case rests almost entirely on the pilot’s testimony, given publicly decades later, with later corroboration from colleagues.
That places it firmly in the interesting-but-unverifiable tier — the same tier as Malmstrom, and for the same reason.
