Iranian President Hassan Rouhani has inaugurated a new domestically-built submarine armed with cruise missiles in line with the Islamic Republic's move to boost its defense power.

The inaugural ceremony for Fateh (Conqueror) submarine was held in the southern port city of Bandar Abbas in Hormozgan Province on Sunday.

Fateh, with a 100-percent domestically-sourced technology, can operate more than 200 meters below the sea surface for nearly five weeks.

Iran's first semi-heavy submarine is capable of carrying and firing cruise missiles that could be launched from a submerged position.
The 527-tonne submarine is also equipped with state-of-the-art weaponry, including torpedoes and naval mines.

Fateh is also outfitted with a guided-missile system and an advanced sonic radar system, which can identify enemy vessels.
Late in November 2018, two Ghadir-class submarines capable of launching subsurface-to-surface missiles, torpedoes and mines joined Iran's naval fleet.
