Iran Made Submarine Nahang-1
Reporter: The Nahang 1 ("Whale") sumarine has joined the navy of the Iranian army. This submarine was designed and manufactured with Iranian knowledge, and it is one of Iran's largest defense programs.
Navy Commander of the Iranian Army, Admiral Sajjad Kouchaki: Nahang 1 is the result of the labor of the navy's scientists, scholars, researchers, and experts. It took a long time, but fortunately, we've managed to design this submarine.
Reporter: The Nahang 1 is fully compatible to conditions in the Persian Gulf. In terms of maintenance and repairs, there is Iranian knowhow. It provides the navy with unique options for its use. Its design and construction involved 220 experts, and 1.2 million hours of scientific and industrial work.
Analysis: More of a delivery vehicle or a mine layer than an attack submarine. It can possibly be designed to sneak into another Gulf countries port and attack anchored vessels. Worst case scenario is that they could use these as suicide ships.
