Underwater Alien UFO Base In Guantanamo Bay? Former U.S. Marine Recalls Heavy UFO Traffic Over Guantanamo Bay Naval Base

A former U.S. Marine who served from 1968 to 1969 at the U.S. Guantanamo Bay Naval Base in Cuba has reported Marines’ experience of UFO activity during the time he was on duty at the base. He said he witnessed UFOs landing in the ocean and taking off from the ocean, indicating there was a major alien UFO underwater base in the bay.

The Marine’s testimony was filed as Case 74794 in the archives of the Mutual UFO Network (MUFON), the largest single UFO sightings documenting and investigating organization in the world.

According to the Marine, who was often assigned to guard the fence area of the facility, he and other Marines were perplexed by the heavy UFO traffic over and around the base. He said UFOs were seen flying over the base almost every night and many flew at altitudes below 300 feet.

The Marines often talked about the UFO activity around the base among themselves but were strictly forbidden to talk about it to outsiders, according to Open Minds.

“All of us Marines were amazed at the amount of UFO activity over and around this base,” he told MUFON investigators. “Virtually every night UFOs were flying overhead with altitudes of less than 300 feet.”

The witness said he saw several UFOs flying overhead because he often stood guard at the south fence of the base. And because they passed over the base at relatively low altitude, he was able to determine that most were about 50 feet to 100 feet across.

They were not brightly colored, but mostly plain-looking with dull colors. He also often saw red lights trailing the UFOs as they flew overhead.

An intriguing observation he made was that many of the UFOs flew towards the ocean, and there was a steady flow of UFOs landing and taking off from the ocean.

It seemed there was a major underwater UFO base in Guantanamo Bay.

He recalled observing moving blue lights, like beacons, each time a UFO flew out to sea to land or when one took off from the ocean.

He told MUFON, “Most of these UFOs were approximately 50 to 100 feet across, but to the naked eye came off as a dull, hazy hull with a small red light trailing behind it.”

“When I stood guard duty on the south side of the base, I witnessed on many, many nights UFOs landing and taking off out of the ocean,” he continued. “There were large blue lights moving around after their landing in the ocean and then slowly dimming down as they obviously descended deeper.”

He went on to describe a bizarre experience he had when he was assigned to stand guard at the main gate of the base. As he stepped out of his guardhouse, one day, at about 7 p.m., he looked over the fence at a deserted guardhouse on the other side and noticed a massive white cloud with blue pulsating lights near the ground.

Alarmed, he called his partner who came out as the UFO rose into the air and flew in their direction.

“I stepped out of the guard shack and looked across the fence… when something caught my eye… a huge white cloud with a baby blue pulsating light in the middle of it.”

“… something caught my eye… a huge white cloud with a baby blue pulsating light in the middle of it.”

He said that as he and his partner watched the approaching UFO, confused about the right action to take, the sentry at the observation tower raised an alarm and began yelling, “get the hell out of there.”

But before they could move, he says the UFO was hovering over them silently. It hovered over them for several minutes as they stood rooted to the ground.

After a few minutes the sergeant in charge called and ordered them to leave. The two men obeyed orders, walked back to the base barracks atop a small hill, and from there continued observing the mysterious flying craft.

Intelligence officers arrived with men carrying filming equipment. The crew filmed the craft which lingered for about three hours before flying west, about a quarter of a mile along the fence line. It paused briefly then shot straight up into the air and out of sight like a bullet.

The Marine’s incredible story is corroborated by previous witness accounts.


The UFO community is familiar with hair-raising tales of mass UFO sightings over Guantanamo Bay Naval Base dating back to the 1950s. Incredible stories of U.S. fighter jets from the Naval Air Station chasing after UFOs are well-known.

According to a witness account, “Many people had seen [UFOs over the base] and… talked openly about it. It was no secret that jet fighters were sent aloft from the Naval Air Station at times to intercept UFOs. A base newspaper [even] published stories about pilots circling around huge motherships hovering high in the sky as smaller UFOs returned to it. The motherships were estimated to be 800 to 900 feet long.”

There are also several incredible accounts of sightings dating back to 1980s – the so-called “Gulf Breeze UFO Incident” — and the 1990s. Military eyewitnesses were adamant that they had not mistaken U.S. aircraft for UFOs.

Reports of UFOs flying out to the sea to land and rising out of the ocean were also very common.
