The exercises, codenamed Mohammad Rasoulallah (Muhammad, the Prophet of God), kicked off early on Monday.
They cover an expanse of three million square kilometers in Iran’s south and southeast, the Makran Coast, and other areas in the Gulf of Oman.
Rear Admiral Seyyed Mahmoud Mousavi, the spokesperson for the maneuvers, told Press TV that the second day of the drills will see surface, anti-surface and anti-aircraft operations by vessels, which have been stationed at the Sea of Oman.
The forces attending the maneuvers will also practice operations involving missile systems and military aircraft as well as intelligence missions, according to the commander.
The Iranian vessels and defense systems have also been monitoring air operations by the mock enemy, reconnoitering targets, and decoding gathered intelligence, he said, adding that the warships further targeted and destroyed projected objectives using artillery and missile systems.
The military exercises also involve the firing of short-range rockets along with medium-range and long-range surface-to-surface missiles, Mousavi pointed out.
Iran’s deputy Army commander for coordination, Habibollah Sayyari, said on Monday that the maneuvers are aimed at improving the defense capabilities of the Army, enhancing the preparedness and morale of the servicemen, and evaluating training tactics, fire power and coordination among Army forces.
The first day of the drills featured firing different precision-strike rockets and using laser-guided artillery. Heavy and light submarines as well as helicopters were also used in the exercises.
Additionally on Monday, the Iranian Army warned off two US-led coalition battleships that had approached the site of the drills for surveillance.
Iranian Armed Forces regularly conduct drills to maintain defensive readiness and to incorporate technologically new weapons systems.
