The movement of enemy vessels in the Persian Gulf is always under the surveillance of the IRGC Navy, Tangsiri said, adding that the Persian Gulf is in complete security.
Stressing that important advanced military equipment is domestically designed and built in Iran, the IRGC Navy commander added that significant progress has been made in this regard.
