U.S. military forces conducted GPS jamming operations near Venezuela in late October 2025, disrupting navigation systems for civilian mariners and aircraft across the Southern Caribbean.
Story Highlights
- GPS jamming lasted one week from October 29 to November 3, 2025, coinciding with USS Gravely destroyer arrival in Trinidad and Tobago
- Electronic warfare expert confirms U.S. military as most likely source of widespread Caribbean GPS disruption
- Civilian cruisers experienced sudden GPS failures, erratic position readings, and frozen navigation systems while other communications remained operational
- USS Gerald R. Ford aircraft carrier subsequently deployed closer to Venezuela as regional tensions escalate
Military Electronic Warfare Targets Venezuelan Waters
GPS jamming operations disrupted navigation systems across the Southern Caribbean between October 29 and November 3, 2025. The USS Gravely guided missile destroyer arrived in Trinidad and Tobago precisely when GPS disruptions began, followed by orders deploying the USS Gerald R. Ford aircraft carrier closer to Venezuelan waters. Multiple independent monitoring organizations, including Defence Blog and Gate Checked, documented widespread GPS blocking activity concentrated near Venezuela and Trinidad and Tobago.
GPS/GNSS disruption over Venezuela has intensified in recent weeks, rising alongside regional military activity and forcing airlines to reroute or suspend flights.
The FAA issued a warning on Nov. 20 citing “heightened interference,” but @Bloomberg's analysis shows the…

Expert Analysis Confirms U.S. Military Capability and Intent
Dr. Thomas Withington, electronic warfare expert at the RUSI thinktank, assessed U.S. military forces as the most probable source of GPS jamming. Withington stated there “aren’t many militaries in that part of the world who would have the capability to disrupt GPS signals in such a widespread way,” effectively identifying the United States as the primary suspect. The expert characterized the jamming as “defensive” operations, suggesting counter-drone systems aboard U.S. vessels targeted perceived threats in the region.
Civilian Navigation Systems Face Unprecedented Disruption
Mariners reported sudden GPS losses, erratic position readings, and boats appearing to “jump half a mile sideways” on navigation displays. The Seven Seas Cruising Association documented that GPS systems failed while satellites, Starlink, and HF radios continued functioning normally, providing diagnostic evidence of intentional jamming rather than equipment failure. Aviation operators experienced similar GPS degradation, forcing reliance on alternative navigation methods during the one-week disruption period. The incident represents the first documented GPS jamming campaign in Caribbean waters, establishing a concerning precedent for electronic warfare in the region.
Regional Tensions Escalate Amid Military Buildup
The GPS jamming coincided with escalating U.S.-Venezuela tensions and military operations in the Caribbean. Secretary of War Pete Hegseth announced strikes against what the Trump administration characterizes as Venezuelan drug trafficking boats, while Venezuelan airspace has been deemed “increasingly dangerous” as U.S. military presence intensifies. The Department of Defence declined to respond to inquiries about GPS jamming operations, leaving official confirmation absent despite expert assessment and circumstantial evidence.
Watch:
GPS navigation systems returned to normal operation by November 4, 2025, ending the week-long disruption. However, the incident raises serious concerns about civilian navigation safety and the potential for electronic warfare to affect non-military operators in strategically significant maritime zones.
