The Iranian Navy has commissioned two Ghadir class diesel-electric submarines to boost Iran’s naval capability, official IRNA news agency reported.
IRNA cited Navy Commander Rear Admiral Habibollah Sayyari as saying that the submarines were built and equipped by domestic manufacturers.
The 120-ton Ghadir class submarines are highly maneuverable and best suited for missions in shallow waters. They are equipped with at least two torpedo tubes and feature elements of "stealth" technology.
With the addition of two new subs, the number of Ghadir vessels in the Iranian Navy has reached 16. The first submarine of this class was commissioned in 2007.
Ghadir class subs have been reportedly designed by Iran on the basis of North Korean Yono class vessels.
In addition to Ghadirs, the Iranian Navy has three Soviet-built Kilo class submarines and a domestically-built Nahang sub.
Iran has recently threatened to block the Strait of Hormuz, a major export route for oil supplies from the Middle East, in response to a Western embargo on Iranian oil exports.
