Turkey Issues Navtex for Research in the Aegean, Greece Responds
October 3, 2025
Turkey issued a Navtex for the research vessel Piri Reis to conduct surveys in the Aegean, claiming areas between Chios and Lesbos. Greece responded with an anti-NAVTEX, stating that the Turkish announcement is illegal. It claims that the areas mentioned fall within the Greek continental shelf. Turkey's previous attempt to launch the Navtex had failed, as the vessel did not go out for research. The situation remains tense, and the exercise 'Parmenion' is currently ongoing.
