TEHRAN (FNA)- Chief of Staff of the Iranian Armed Forces Major General Hassan Firouzabadi said a significant part of Iran's naval capabilities has been kept secret for the "rainy day".

"We have upgraded our naval capabilities. Our enemies know little about what we are capable of. If they have heard something about it, that has been by design. They know nothing of the decisive parts," Firouzabadi said Sunday while addressing a number of military commanders on the sidelines of the naval drills in the Persian Gulf and the Sea of Oman.

At the end of the drills, the top military commander said the enemies know what the public already knows about Iran's naval deterrence power, noting that even if they find out more, they stand no chance against Iran.

Iran ran major naval wargames in its waters in the Persian Gulf. The high-profile Velayat exercises is an annual event and all shipping lines and naval vessels in the region are informed of the area of the drills according to international maritime and naval standards that require all foreign ships and vessels to keep some 5 nautical miles away from the wargames zone.

Last Wednesday, a US Navy warship received serious warnings from several Iranian destroyers to keep away from the drill zone near the Strait of Hormuz, an incident that can keep frictions high after Iran captured 10 US marines in the Persian Gulf earlier this month.

Also, the Iranian Navy's unmanned aerial vehicle and a submarine recorded images of a US aircraft carrier on the third day of the main phase of the massive wargames underway along the country's Southeastern Makran seashores on the rims of the Persian Gulf on Friday.

The Navy's drone captured a video during the surveillance mission over the US aircraft carrier.

Meantime, a Qadir-class submarine also belonging to the Iranian Navy was also deployed close to the US aircraft carrier with a mission to gather intelligence and capture video of the US vessel's moves.

The Iranian submarine managed to take clear pictures of the aircraft carrier without catching the attention of the staff on board.

Also on Saturday, the Iranian Naval forces launched multiple torpedoes from heavy Tareq-class and Qadir-class submarines that successfully hit the targets. Also Jamaran and Alvand destroyers fired torpedoes at surface and subsurface vessels on the forth day of the main phase of the massive 'Velayat 94' wargames in the Persian Gulf.
