The U.S. Marine Corps has begun installing a sophisticated radar system at Tobago’s ANR Robinson International Airport, a development confirmed by Trinidad and Tobago’s prime minister after earlier assertions that no U.S. troops remained in the country. While the government publicly presents the project as a counter-narcotics initiative and airport infrastructure upgrade, its proximity to Venezuela and advanced technical characteristics suggest a wider role in regional maritime and airspace monitoring.
Reports from the Trinidad and Tobago Guardian and open-source intelligence point to the radar in question being the AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR). This mobile active electronically scanned array sensor replaces multiple legacy systems by combining air-defence surveillance, artillery fire detection, and expeditionary air-traffic control in one platform. Operating in the S-band with a detection range exceeding 160 km, the radar would be able to observe much of the southern Caribbean and Venezuelan approaches when positioned in Tobago.
The deployment comes amid expanding U.S. security initiatives in the Caribbean, including increased counter-narcotics missions and new military cooperation agreements. Capable of tracking aircraft, cruise missiles, drones, rockets, and artillery rounds, the G/ATOR system is field-deployable within an hour and can be airlifted using C-130 aircraft or heavy-lift helicopters—giving Washington considerable operational flexibility and signalling strategic intent beyond the stated counter-drug mission.
