Speaking to reporters on Wednesday, the defense minister said the Iranian submarine is undergoing tests, whose results will determine when the vessel would enter service.

The 527-ton Fateh submarine is considered a semi-heavy undersurface vessel whose weigh at depth increases to 593 tons. The submarine is equipped with an advanced sonic radar system for identifying enemy vessels and uses a missile defense system.

Thanks to Fateh, the Iranian Navy is now equipped with a full range of light, semi-heavy and heavy submarines.
