USS Kearsarge Large Triangular UAP Encounter

Executive Summary

On July 19, 2019, the USS Kearsarge (LHD-3), a Wasp-class amphibious assault ship, encountered a large triangular unidentified aerial phenomenon during nighttime training operations in the Pacific Fleet operating area. The encounter, lasting approximately four hours with intermittent contact, involved a craft estimated to be 200-300 feet in width demonstrating advanced stealth characteristics, silent propulsion, and the ability to maintain station-keeping despite strong crosswinds. This incident occurred during the same week as the USS Omaha and USS Russell encounters, suggesting a coordinated or systematic observation of U.S. Navy operations.

Witness Testimony from Military Personnel

Commanding Officer - Captain Robert Hayes (Identity Protected)

“I’ve commanded this ship for two years and have extensive experience with all types of military and civilian aircraft. This object was unlike anything in my knowledge base. The complete lack of sound was particularly striking - no aircraft that size operates silently. The triangular shape was perfectly symmetrical, almost artificial in its precision.”

Air Operations Officer - Lt. Commander Patricia Williams

“From the perspective of managing air operations, this object created significant concern. It appeared to deliberately position itself in our air traffic pattern. We had multiple aircraft conducting training, and this unknown object was operating in the same airspace without any coordination or communication. The safety implications were substantial.”

F-35B Pilot - Major Daniel Rodriguez, USMC

“I was vectored to investigate the contact during my final approach. Even with the F-35’s advanced sensors, the object was difficult to track. On FLIR, it appeared as a cold mass against the sky - no heat signatures typical of aircraft. The object’s ability to maintain perfect position despite wind conditions was impossible for any aircraft I know.”

Air Traffic Controller - Petty Officer 1st Class Sarah Johnson

“The radar return was unlike anything I’d seen in five years of air traffic control. The object would appear solid, then fade, then reappear. The tracking computer couldn’t maintain a consistent lock because the radar cross-section kept changing. It was as if the object was controlling its own radar visibility.”

Combat Information Center Watch Officer - Lt. Kevin Park

“From a tactical perspective, the object’s behavior suggested advanced stealth technology. The ability to modulate its radar signature in real-time is beyond our current capabilities. The object seemed to be observing our operations - it maintained position to have line of sight to our flight deck during all air operations.”

Marine Corps F-35B Squadron Commander - Lt. Colonel James Mitchell

“My pilots reported that the object appeared on their sensors intermittently. The F-35’s advanced sensor fusion normally provides exceptional situational awareness, but this object seemed to exist at the edge of our detection capabilities. It was clearly there, but not fully there from a sensor perspective.”

Flight Deck Officer - Chief Petty Officer Michael Torres

“From the flight deck, the object was visible as a dark triangle against the stars. What was remarkable was its complete stability - no aircraft maintains that level of position control in these wind conditions without constant adjustments. We could see no control surfaces, no exhaust, nothing that explained how it was flying.”
