An Iranian destroyer and support vessel are now sailing in the Atlantic Ocean on a rare mission far from the Islamic Republic, Iran’s state TV has reported, amid speculation that the ships could be bound for Venezuela.

The destroyer Sahand and the intelligence-gathering vessel Makran departed last month from Iran’s southern port of Bandar Abbas, said Adm Habibollah Sayyari, Iran’s deputy army chief, on Thursday. He described the mission as the Iranian navy’s longest and most challenging voyage yet, without elaborating.

Iranian state TV released a short clip of the destroyer cruising through the Atlantic’s rough seas. The video was most likely shot from the Makran, a converted commercial oil tanker with a mobile launch platform for helicopters.
