Over the last two years, an antenna field at the northeast end of the facility has been converted from a linear antenna grid to a CDAA. Imagery published by CSIS in April 2025 captured ongoing groundwork to lay cables between the antennas and the central control facility. Construction now appears to be complete and the facility has very likely begun operations.
The array of 32 antennas (19 outer and 13 inner) is larger and likely more capable than any Cuban CDAA previously observed by CSIS. CDAAs are primarily used for high-frequency direction finding, which involves intercepting and geolocating incoming radio transmissions over a wide range of frequencies.
From Bejucal's location in Cuba's northwest, the CDAA could improve the ability of Cuban authorities—or potentially their foreign partners—to monitor sensitive U.S. activities in the Caribbean and across the southeastern seaboard. U.S. naval and air operations in the region have escalated amid the Trump administration's prioritization of the Western Hemisphere, increasing the potential value of monitoring U.S. movements in the Caribbean and the Gulf of Mexico."
