Iran on Friday began large-scale naval drills in the Persian Gulf, which will feature its first submarine cruise missile launches, the state news agency IRNA reported.
More than 100 vessels were taking part in the three-day war games in a vast area stretching from the Strait of Hormuz to the Indian Ocean, according to reports.
"The exercise will cover confronting a range of threats, testing weapons, and evaluating the readiness of equipment and personnel," navy commander Rear Admiral Hossein Khanzadi, said in remarks carried by state television.
"Submarine missile launches will be carried out ... in addition to helicopter and drone launches from the deck of the Sahand destroyer," Khanzadi said.
State media said Iran would be testing its new domestically built Fateh (Conqueror) submarine which is armed with cruise missiles and was launched last week.
Iran launched its domestically made destroyer Sahand in December, which official say has radar-evading stealth properties.
Iran displayed a new cruise surface-to-surface missile with a range of 1,300 km (800 miles) earlier this month during celebrations marking the anniversary of the 1979 Revolution.
