Pentagon tests device for Havana syndrome for a year: what is known.

According to ТСН: The United States Department of Defense has been testing a device for over a year that, according to experts, may be linked to the 'Havana syndrome' — a series of unexplained ailments among American diplomats, military personnel, and intelligence workers.

The device was acquired as part of a secret operation by the Department of Homeland Security’s Homeland Security Investigations (HSI) at the end of the Joe Biden administration. According to sources, the purchase was funded by the Pentagon and cost 'eight figures' in dollars.

Details about the device

So far, the device is still being studied. Discussions continue within the U.S. government, and there are skeptical assessments about its possible connection to numerous anomalous illness episodes, the causes of which remain unclear.

One source reported that the device generates pulsed radio waves, which have long been considered a possible factor in the development of these incidents. It should be noted that although the device is not entirely of Russian origin, it contains Russian components. It is unknown how this powerful technology could be portable, as estimates suggest that the device could fit in a backpack.

Havana syndrome

The procurement of this equipment has again drawn attention to the 'Havana syndrome,' first identified in late 2016 among American diplomats in Havana. These diplomats began to report symptoms similar to traumatic brain injuries, including severe headaches and dizziness. Later, similar cases began to be recorded in other countries.

Over the years, American intelligence agencies and the Pentagon have tried to determine whether these cases could be the result of a deliberate energy attack by other countries. In 2022, one intelligence committee suggested that some cases 'possibly' could have been triggered by pulsed electromagnetic energy. However, in 2023, the intelligence community stated that it had no evidence of foreign adversaries' involvement, and in January 2025, this assessment remained unchanged, although individual cases were not completely ruled out.

This position has sparked outrage among the victims. Some of them believe that the U.S. government has ignored or concealed evidence of possible Russian involvement. Former CIA officer Mark Polymeropoulos, who claimed to have been a victim of an attack in Moscow in 2017, called the testing of the device a potential affirmation of the victims' words and urged American intelligence to publicly apologize for its treatment of them.

No official comments have been received on this matter from the Pentagon, HSI, or the Department of Homeland Security. The CIA has also withheld comments.

This situation underscores the ongoing discussions surrounding the 'Havana syndrome' and the possible causes of its emergence. Concerns are raised not only about the health of the victims but also about security, which may become an important aspect for American diplomats and military personnel in the future. The testing of the device and its possible link to this mysterious illness leaves many questions open that society may soon receive answers to.
