- In recent history, the first reports of a potential directed-energy attack on U.S. personnel came in 2016 from American diplomats working in Cuba.
- There's no "smoking gun" evidence of who's behind the attacks, but some U.S. officials suspect the Russians.
- Supporting that claim is the history of the so-called Moscow Signal, an event in which the Soviets blasted microwaves at the U.S. embassy in Moscow from 1953 to 1976.
Since 2016, more than 130 U.S. government personnel have suffered symptoms linked to Havana syndrome, an acute illness marked by sudden headache, nausea, and the hearing of loud sounds, akin to swarming cicadas. The cause of the illness remains a mystery. But a growing number of U.S. intelligence personnel and researchers fear that some form of "directed-energy" weapon — possibly firing microwave radiation — is to blame.
One of the first cases was reported in Havana, Cuba in 2017. The victim, if it indeed was an attack, was a U.S. Foreign Service officer who was living in a quiet Havana neighborhood among other American personnel. One night she was cleaning her kitchen. If it had been daytime, her kitchen window would have offered a view of a booth outside where Cuban police monitored foreigners like herself.
But at night, the kitchen's interior lights obstructed her view of the booth, The New Yorker reported. As she was cleaning, she suddenly felt a painful burst of pressure inside her head. The pain grew. She had heard rumors of U.S. personnel suffering strange "sonic attacks," and she remembered that a security officer had once advised: to protect yourself, step away from your current position. She did. The pain decreased. But for weeks she suffered headaches, dizziness, and confusion.
Over the past five years, at least 130 U.S. personnel have reported similar symptoms while working in places like China, Russia, and Washington, D.C. The cases vary in severity, but almost all involve sudden headaches and nausea. Some victims may have brain injuries.
A 2019 study published in JAMA found that victims had "significantly smaller" white matter volume and other "significant differences" in brain structure, though it's impossible to determine whether these differences were pre-existing or stem from a directed-energy attack.
What's causing Havana syndrome?
The U.S. hasn't reported a definitive cause of these cases, but intelligence agencies are actively investigating the possibility that bad actors are using some type of directed-energy weapon against U.S. personnel.
A December 2020 report from the National Academies of Sciences found that pulsed radiofrequency energy, which includes microwave radiation, "appears to be the most plausible mechanism in explaining these cases among those that the committee considered." (Other potential causes included infection and chemicals.)
A microwave weapon seems like a fitting culprit. One reason is that sufferers of Havana syndrome often hear loud noises, which is a phenomenon that's known to happen when people are bombarded with high-powered microwaves. In the 1960s, the American neuroscientist Allan H. Frey demonstrated that exposing people to microwaves can make them hear buzzing, clicking, hissing, and speech — even though the microwave device didn't produce any soundwaves. It was all, quite literally, in their heads.

How is that possible? Researchers have hypothesized that the noises are induced by thermoelastic expansion of bones and soft tissue in the body: As microwaves strike people, it slightly warms the body, which causes expansion. This expansion might produce soundwaves that travel to the ear. Frey and other researchers have proposed different theories about which parts of the body are expanding — those in the head, or those in the ear — but the principle is the same.
To induce auditory effects, a pulsed-microwave weapon needs to transmit 40 joules per square centimeter, according to a U.S. Army report. How much energy is that? Here's how astrophysicist Dr. Ethan Siegel explained it to the American Council on Science and Health (ACSH): "If you are talking about 40 J/cm2 over the entire human body, that's about as much energy as a fully loaded Harley Davidson going 100 mph."
The Moscow Signal
We know such weapons exist, or at least did at one time. During the Cold War, the Soviet Union fired microwaves at the U.S. embassy in Moscow from a nearby apartment building for more than two decades, from 1953 to 1976. The event was dubbed the Moscow Signal.
U.S. intelligence officials initially thought the Soviets were firing the microwaves in an attempt to control the minds of American personnel, but they later reasoned that the Soviets were trying to activate espionage devices inside the building or interfere with the health of the diplomats. To this day, "many questions remain unanswered" about the long-term health effects incurred by Americans who worked at the U.S. embassy in Moscow, according to a 2019 review.

A more recent example of an energy-directed weapon is the active denial system, an American technology that uses non-lethal millimeter waves for crowd control. These waves, which the U.S. says are not classified as microwaves, cause a painful heating sensation on the skin. The U.S. is also developing or has developed stronger directed-energy weapons, including microwave weapons that can destroy electronic systems from a distance.
Still, if energy-directed weapons are indeed causing Havana syndrome, what they look like and how they operate remains a mystery.
Who's behind the directed-energy attacks?
There's currently no "smoking gun" evidence for who's responsible for the attacks. But in December 2020, the CIA established a task force to investigate the more than 130 reported cases of Havana syndrome among U.S. personnel. In April, President Joe Biden's administration recently released a statement:
"The White House is working closely with departments and agencies to address unexplained health incidents and ensure the safety and security of Americans serving around the world. Given that we are still evaluating reported incidents and that we need to protect the privacy of individuals reporting incidents, we cannot provide or confirm specific details at this time."
Although the U.S. hasn't officially announced suspects, an anonymous former national security official involved in investigations recently told Politico that Russia is likely behind the attacks. Specifically, the official pointed to Russia's foreign military intelligence agency, commonly called the GRU, whose operatives were present in the locations where American personnel have reported Havana syndrome.
"It looks, smells, and feels like the GRU," said the official. "When you are looking at the landscape, there are very few people who are willing, capable and have the technology. It's pretty simple forensics."
Why Russia would carry out these attacks remains unclear. But the cases have already had a measurable impact on U.S. foreign policy, namely a 50-percent personnel withdrawal from the American embassy in Cuba, a nation that's long been allied with Russia.

While U.S. intelligence agencies now seem to be taking these threats seriously, that wasn't always the case. In the first few years after Americans first reported Havana syndrome, some officials were skeptical of the idea that a foreign adversary would launch such brazen attacks, especially on U.S. soil. Some current and former officials say this skepticism has come at the expense of U.S. personnel.
Marc Polymeropoulos, a former CIA officer who was struck by Havana syndrome in a Moscow hotel room in 2017, told the New York Times about a painting created by a fellow CIA officer and Havana syndrome victim. Called "The Gunshot," the painting depicts a red splatter on a black background.
"It signified his feeling that we all wished we had been shot, a visible injury, so that our colleagues would more readily believe us."
