Speaking to reporters in Tehran on Saturday, Rear Admiral Khanzadi said the domestically made submarine is planned to come into service on January 29.
In an interview with Tasnim in August, Khanzadi said the fact that Iran has the technical know-how to manufacture submarines indicates that the country has no limitations in producing other military equipment.
The 527-ton Fateh submarine is a semi-heavy undersurface vessel whose weight 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.
Once Fateh joins the Iranian Navy fleet, it will be equipped with a full range of light, semi-heavy and heavy submarines.
