Azerbaijan, Baku, June 27/Trend M. Moezzi
With three super-heavy submarines operating in the Persian Gulf, Iran is seeking to use lighter submarines in the Caspian Sea.
Admiral Abbas Zamini told Fars news agency that Iran's navy has made huge gains and become self-sufficient in designing, building and repairing its own submarines.
Iran is producing semi-heavy submarines with the goal of building super-heavy ones in the future.
The projects are part of an overall strategy to expand Iran's naval fleet and presence in international waters. Currently, battle groups are getting ready to set sail for the north Indian Ocean, the Red Sea, the Suez Canal, the Mediterranean and the Gulf of Aden.
An exercise outside Iran's border kept a super-heavy submarine under water for 67 days in the Red Sea.
In February, Iran's navy sent ships through the Suez Canal for the second time since Iran's revolution.
