Iran's state TV is reporting that the country's President Hassan Rouhani has unveiled the first Iranian made semi-heavy submarine.
The Sunday report said the Fateh, "Conqueror" in Persian, is capable of being fitted with cruise missiles.
Since 1992, Iran has developed a homegrown defense industry that produces light and heavy weapons ranging from mortars and torpedoes to tanks and submarines.
The Fateh has subsurface-to-surface missiles with a range of about 2,000 kilometers (1,200 miles), capable of reaching Israel and U.S. military bases in the region.
Last week, The New York Times reported that the Trump White House has accelerated a secret program to sabotage Iran's ballistic missile and rocket projects.
