Joint drills involving air, land, and naval forces -- including both drones and submarines -- will take place around the southeastern port of Jask "east of the Strait of Hormuz", deputy coordinator of the armed forces Admiral Habibollah Sayyari told IRNA.
The Strait of Hormuz is the strategic chokepoint at the head of the Gulf through which a fifth of world oil output passes.
Exercises will involve "infantry, armored and mechanized units of the ground forces, defense systems of the air defense force (and) subsurface and surface vessels", he said.
Naval forces with the support of "strategic bombers of the air force" will also take part.
Sayyari said that drones will practice "information-gathering operations against attacking forces as well as reconnaissance operations".
During similar exercises last year, Iran's military said it warned off two US drones that overflew waters where the drills were being held.
