For nearly a decade, the U.S. intelligence community maintained that Havana Syndrome—the cluster of neurological symptoms reported by over 1,500 American officials across dozens of countries—was 'very unlikely' caused by a foreign adversary. The most persistent objection: where's the weapon?
Now there are two devices under investigation, one purchased by the Pentagon for over $10 million, another built by a Norwegian scientist who developed the symptoms he'd spent years arguing were impossible. In February 2026, the CIA and Pentagon confirmed they had examined the Norwegian device. The scientist developed neurological symptoms—headaches, vertigo, memory loss, hearing loss—marking the first documented evidence that pulsed-energy weapons can produce Havana Syndrome-like effects in a controlled setting.
The evidence has shifted dramatically. A joint investigation by The Insider, 60 Minutes, and Der Spiegel geolocated operatives from GRU Unit 29155—the Russian unit responsible for the Novichok poisoning of Sergei Skripal—near attack sites in multiple countries. House Intelligence Committee leaders sent criminal referrals to the Department of Justice in September 2025, accusing the intelligence community of 'stonewalling' and 'cherry-picking' evidence.
The question is no longer whether such weapons could exist. The House Intelligence Committee and the joint investigation team say the government has known about such weapons for years. The Norwegian experiment may force the intelligence community to reconsider its 'very unlikely' conclusion.

Norwegian Scientist's Self-Experiment Confirmed by CIA and Pentagon
LatestInvestigation
CIA and Pentagon officials confirm they examined a device built by a Norwegian government scientist who developed neurological symptoms—including headaches, vertigo, memory loss, and hearing loss—after self-testing pulsed microwave energy in 2024. The experiment provides first documented evidence that directed-energy devices can produce Havana Syndrome-like symptoms.

First Reported Case in Havana

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
1953-1979
The Moscow Signal (1953-1979)
For over two decades during the Cold War, the Soviet Union beamed microwave radiation at the U.S. Embassy in Moscow. First detected in 1953, the transmissions were aimed at the embassy building from Soviet installations nearby. American personnel reported elevated white blood cell counts, and an unusual number of cancer cases emerged among former embassy staff.
Then
The State Department installed aluminum window screens and offered hardship pay to Moscow personnel. Two ambassadors reportedly died of cancer, though causation was never proven.
Now
The incident established precedent for Soviet/Russian use of directed energy against U.S. diplomatic facilities. It remained classified for decades and is now cited by Havana Syndrome investigators as a direct predecessor.
Why this matters now
The Moscow Signal demonstrates that Russia has a multi-decade history of targeting U.S. diplomatic facilities with directed energy, and that the U.S. government has previously kept such incidents from the public.

March 2018
Skripal Novichok Poisoning (2018)
GRU Unit 29155 operatives Anatoliy Chepiga and Alexander Mishkin traveled to Salisbury, England, and applied Novichok nerve agent to the door handle of former Russian spy Sergei Skripal's home. Skripal and his daughter Yulia survived; a British citizen, Dawn Sturgess, later died after exposure to the discarded nerve agent container.
Then
153 Russian diplomats were expelled from Western countries—the largest such expulsion since the Cold War. The UK identified the perpetrators using CCTV footage and open-source intelligence.
Now
The incident established Unit 29155's willingness to conduct attacks on foreign soil using unconventional weapons, accepting significant collateral damage and diplomatic costs.
Why this matters now
The same unit now implicated in Havana Syndrome incidents previously demonstrated its capacity and willingness to attack individuals abroad with exotic weapons. The Skripal case also showed how open-source investigators could identify GRU operatives—a methodology now applied to Havana Syndrome.

1990-2008
Gulf War Syndrome Recognition (1990s-2000s)
Following the 1991 Gulf War, thousands of veterans reported unexplained symptoms including fatigue, pain, and cognitive difficulties. Initial government studies dismissed the condition as stress-related or psychosomatic. Veterans advocated for recognition while facing skepticism from military officials.
Then
Veterans struggled to obtain disability benefits and medical care for conditions the government didn't recognize as service-connected.
Now
After years of research and advocacy, Congress passed legislation in 2008 formally recognizing Gulf War Syndrome. Studies eventually identified potential causes including chemical exposures and environmental factors.
Why this matters now
Gulf War Syndrome demonstrates how government agencies may initially dismiss unexplained illness clusters affecting personnel, only to reverse course after sustained advocacy and independent research—a pattern Havana Syndrome victims hope to repeat.
