US surveillance aircraft have been detected operating off the coast of Venezuela by open-source tracking of their transponder signals.
Boeing RC-135 Rivet Joint signals intelligence (SIGINT) aircraft of the US Air Force (USAF) have been tracked patrolling off Venezuela on at least five occasions since 23 February, while a Lockheed Martin EP-3E Aries II SIGINT platform was identified on 8 March.
