Spy Antennas Bloom 90 Miles Away

Just 90 miles off our shore, a powerful new Cuban antenna field likely tied to China is now listening in on America’s military backyard.

Story Snapshot

New satellite imagery shows a massive 32‑antenna circular array at Cuba’s Bejucal signals site is complete and likely operational.
Analysts say the system can track U.S. radio and radar signals across Florida, the Gulf, and the wider Caribbean, threatening U.S. security.^[3]
The site has long been linked to Chinese intelligence activity, though public proof of direct Chinese control remains disputed.^[3]^[6]^[16]
Experts warn the base could map U.S. military patterns near Key West, Cape Canaveral, and other critical installations.^[5]^[17]

Massive Cuban Antenna Field Comes Online Near U.S. Shores

Recent analysis from the Center for Strategic and International Studies (CSIS) confirms that construction of a large circular antenna complex at the Bejucal signals site, just south of Havana, is now complete.^[3] Satellite images show that an older linear antenna field was torn out and replaced with a circularly disposed antenna array featuring 32 antennas in two rings.^[3]^[2] These arrays are designed for high‑frequency direction finding, which means they can intercept and locate radio signals over long distances across many channels.^[3]

CSIS notes that this new build is larger and more capable than any previous Cuban antenna system they have seen at the site.^[3]^[4] Reporting says similar arrays have been used elsewhere to track signals thousands of miles away, including military communications and radar emissions.^[1] From Bejucal’s position in northwest Cuba, analysts warn the system could monitor sensitive U.S. activities in the Caribbean, the Gulf of Mexico, and the southeastern United States, including parts of Florida just a short hop across the water.^[2]^[5]

Why Bejucal Worries U.S. Military Planners

Bejucal is not a new name in intelligence circles. The base first gained attention during the Cuban missile crisis as a storage site for Soviet nuclear weapons.^[1] In recent decades, it evolved into Cuba’s largest active signals intelligence hub, with multiple antenna fields, hardened buildings, and even underground facilities built between 2010 and 2019.^[2]^[16] U.S. and allied reporting has long suggested the site can monitor satellite links and other communications that pass over the region, including traffic tied to U.S. military forces.^[1]^[7]^[16]

Analysts and officials say the new array could sharpen that threat. CSIS and other experts warn that facilities like Bejucal may be less about reading encrypted messages word‑for‑word and more about learning how U.S. systems behave.^[3]^[17] By listening to signal patterns from bases near Key West, Homestead, and Cape Canaveral, a foreign power can build detailed maps of radar coverage, radio networks, and routine flight or ship movements.^[5]^[17] That kind of insight can weaken deterrence and give adversaries a head start in any crisis close to America’s coast.

China’s Shadow: Likely Partner, Still No “Smoking Gun”

The sharpest concern is who might be using Bejucal’s new ears. For years, media reports, congressional testimony, and think tank studies have tied the site to Chinese intelligence ambitions, often citing anonymous officials or leaked documents.^[2]^[16]^[18] A Federal Communications Commission report, summarizing earlier U.S. assessments, said that the Chinese Communist Party maintains a physical presence at Soviet‑era facilities at Bejucal for signals collection.^[10] Other analysis argues that the level of technology and recent upgrades exceed what cash‑strapped Cuba could easily field on its own.^[8]

Yet the open record still has gaps. CSIS itself stresses that there is no clear publicly available proof that China directly runs Bejucal, even while calling it one of the sites most likely supporting Chinese intelligence targeting the United States.^[3]^[7]^[16] Cuban officials flatly deny any foreign bases on their soil and insist the facilities are Cuban‑run.^[6]^[14] Investigative reporters who visited nearby towns heard locals say the base has been there for years and belongs to the Cuban military, not China or Russia.^[6] Former intelligence officers quoted in that work add that large antennas can have non‑espionage uses, such as space tracking or drug interdiction.^[6]

Competing Narratives and the Stakes for U.S. Security

This split in the evidence has fed a wider fight over how to read satellite imagery. On one side, groups like CSIS argue that Bejucal, plus three other Cuban sites at Wajay, Calabazar, and El Salao, most likely support Chinese signals collection against U.S. forces and allies.^[3]^[16] Wall Street Journal reporting, based on unnamed U.S. officials, has described secret agreements for Chinese eavesdropping facilities and new joint training sites, including work near the U.S. base at Guantanamo Bay.^[7]^[18] These accounts portray a slow but steady move by Beijing to build a listening network in America’s backyard.

China's spy base at Bejucal in Cuba went operational this week, confirmed by new satellite imagery, while Washington's fuel blockade pushes the island toward collapse and a fresh migration wave. A breakdown:

On the other side, critics at the National Security Archive and independent outlets argue that much of the public case rests on inference and politics, not hard proof.^[6]^[4] They point out that CSIS and major media often use careful language like “could,” “likely,” and “suspected,” while still stirring public fear of “China spy bases.”^[6]^[1] These skeptics warn that vague claims can be used to justify more sanctions on Cuba or to distract from past policy failures, without giving citizens clear facts about what foreign powers can actually do from these sites.

How the Trump Administration Can Respond

For Americans who care about sovereignty, the core issue is simple. A hostile power should not be able to sit just off our coast and quietly vacuum up data on our troops, ships, and launches. Under the Trump administration’s second term, the burden now falls on U.S. leaders to cut through spin and deliver clear, public assessments. That means pressing the intelligence community to declassify what can be safely shared about Bejucal’s ownership, tasking, and links, while also updating Congress on real risks to nearby bases.

Policy tools range from increased electronic hardening and better encryption to targeted diplomatic and economic pressure on Havana and Beijing. Unlike the previous globalist approach, which often downplayed these threats, a security‑first strategy would treat Cuba’s signals sites as part of a larger Chinese push against the United States, from the South China Sea to the Caribbean.^[3]^[16]^[17] The American people deserve straight answers about what those antenna fields are hearing—and a firm plan to make sure they do not drown out our own voice in our hemisphere.
