Russian warships maneuver in the Adriatic Sea off Croatia, allegedly attempting to block access for a US aircraft carrier.

Croatian sources reported that a group of Russian naval vessels entered the Adriatic Sea and conducted corridors of presence near the Croatian maritime zone, with one statement indicating they “blocked the entry-exit route from the Adriatic Sea to try to prevent the movement of the American aircraft carrier”. The Croatian Ministry of Defence did not issue a formal protest immediately, but Croatian naval and maritime-security analysts noted the event as a provocative transit. Geographically, the operation took place within Croatia’s maritime approaches, underscoring how hybrid-warfare can extend into the Adriatic littoral rather than just land borders. The dynamics suggest that Russia employed naval assets in a show-of-force and disruption capacity: by traversing a route used by NATO/US carriers, they imposed risk and forced allied assets to adjust. While no damage or overt strike occurred, the transit itself functioned as a coercive gesture and reconnaissance of maritime passages. The incident highlights how Russia’s hybrid methods may involve “grey zone” maritime operations in alliance waters.
