Just 240 miles from American shores, a massive Cuban antenna field tied to Chinese spying has quietly gone from construction site to likely operational listening post targeting our homeland.

Story Snapshot

• A new 32-antenna circular array at Cuba’s Bejucal base is now complete and likely active, boosting foreign eavesdropping close to the U.S.^[9]
• The system can help intercept and locate radio signals across wide areas, including U.S. military and civilian communications.^[1]
• Analysts and U.S. officials link Bejucal and three other Cuban sites to Chinese intelligence efforts, even as Beijing and Havana deny control.^[9]
• There is still no “smoking gun” in public data proving China runs the site, but experts warn the risk to U.S. security is real.^[8]

New Cuban Antenna Field Puts Foreign Ears on America’s Doorstep

Satellite imagery reviewed by the Center for Strategic and International Studies shows that construction at the Bejucal signals intelligence site, south of Havana, is now finished.^[9] Over the last two years, crews tore out a previous linear antenna grid and replaced it with a large circularly disposed antenna array, or CDAA, tied by underground cabling to a central operations building.^[9] Analysts say the antenna field now appears complete, and they assess the site has very likely begun operations as an advanced listening post.^[9]

The finished array at Bejucal consists of 32 antennas, with 19 forming an outer ring and 13 in an inner circle, making it larger and more capable than any Cuban array previously documented by CSIS.^[9] CDAA systems are primarily used for what experts call high-frequency direction finding, which means they can intercept and pinpoint the source of radio transmissions across a broad span of frequencies.^[9] In plain terms, foreign operators can listen, measure where signals come from, and build a detailed map of activity close to U.S. coasts.

How the Bejucal Site Strengthens Foreign Eyes and Ears on U.S. Forces

Bejucal has long been known as Cuba’s largest active signals intelligence site, with roots going back to the Soviet period.^[3] Earlier imagery showed a smaller circular array about 85 meters across with 16 antennas, but that older system has now been removed and replaced by the far larger field.^[3] CSIS and other analysts say this upgrade gives the site a significantly enhanced ability to monitor air and maritime traffic and intercept sensitive communications in and around the United States, including near Florida’s dense cluster of military bases.^[4]

Reports drawing on open-source satellite analysis describe four Cuban sites—Bejucal, Wajay, Calabazar, and El Salao—as a broader network that could support foreign intelligence on U.S. targets.^[14] At Bejucal and Calabazar, large dish antennas appear suited for tracking or talking with satellites, a mission that meshes well with China’s expanding space program and global surveillance push.^[7] A newer site at El Salao, near the U.S. naval base at Guantanamo Bay, is being built to host another large circular array that could eventually monitor electronic signals linked to that base and surrounding sea lanes.^[2]

China’s Suspected Role, Denials, and What We Really Know

For years, U.S. officials, congressional testimony, and multiple media reports have linked Bejucal and the other sites to Chinese intelligence collection against the United States.^[3] Research by CSIS in 2024 and 2025 used commercial imagery to identify these four facilities as the most likely locations supporting China’s efforts to gather U.S. signals from Cuban soil.^[14] A separate expert statement to the House Homeland Security Committee concluded that China has built or upgraded at least four such sites aimed at intercepting sensitive communications from America’s southeastern seaboard.^[8]

CSIS: Chinese Spy Antenna Array at Cuba's Bejucal Base Is Now Operational

Yet even as the new 32-antenna array comes online, analysts stress one key point: there is still no clear, publicly available proof that China formally owns or directly operates Bejucal.^[9] CSIS itself notes there is “no smoking gun” in unclassified information, even while judging the site is likely one of three in Cuba that U.S. officials privately acknowledge as Chinese-run.^[9] China and Cuba continue to deny Beijing’s control, but the pattern of construction, the technology involved, and repeated U.S. warnings have convinced many experts that Beijing is at least getting access to the data.^[8]

What This Means for American Security and Everyday Citizens

From a security standpoint, the concern is simple and serious: a hostile power, working with a communist regime just off our coast, may now have a powerful tool to listen to U.S. military communications, track ship and aircraft movements, and map our response patterns in a crisis.^[1] Analysts warn that such a listening post can also help foreign planners test ways to jam, spoof, or disrupt American systems in a future showdown, whether over Taiwan, the Caribbean, or our own coastal waters.^[3]

For American families already worried about border chaos, globalist deals, and the steady erosion of national strength, this development feels like another bill coming due from years of weak policy.^[15] Prior administrations allowed China to expand its reach in our hemisphere while downplaying the threat, and now a high-end antenna farm aimed at our backyard appears to be up and running.^[16] The Trump administration’s second term must now manage this reality, tighten defenses, and ensure that America—not Beijing or Havana—sets the rules in our own neighborhood.
