Philippine Sea: USS Hassayampa radar/visual UAP

Event Details On 5. Mai 1965 at 1:10 Uhr local time, the crew of the USS Hassayampa, a US Navy fleet replenishment ship, spotted an approaching aircraft while positioned in the Philippine Sea. Four minutes later, the ship's SPS-6C radar registered four targets at distances reaching 22 miles, tracking them for six minutes at speeds around 3.500 mph with diverse maneuvers.

Observations and Evidence Visually, through binoculars, witnesses saw three illuminated objects: one as bright as first-magnitude stars, the others second-magnitude. These hovered directly above the vessel for three minutes. No IFF (Identification Friend or Foe) signal was received. Radar indicated one object to starboard was notably larger. The targets then accelerated southeast at extraordinary velocity.

Witnesses and Context The observers were the trained crew of a military vessel, providing dual radar-visual confirmation. Sources highlight this as a significant maritime UAP case linked to aviation safety concerns.

Significance This incident exemplifies high-speed, maneuverable UAP tracked by naval radar, unresponsive to identification protocols, underscoring military encounters with unexplained aerial phenomena.
