The Nahang class (Persian: نهنگ) is an Iranian made submarine class.

The "Nahang" submarine is Iran's second attempt at designing and manufacturing submarines, and it is one of Iran's largest defense expenditures. The Nahang 1 is fully compatible to conditions in the Persian Gulf. It provides the navy with varied options for its use. Its design and construction involved 220 researchers, and 1.2 million hours of scientific and industrial work.

After the Ghadir submarine, the Nahang submarine is Iran's second domestically-produced submarine and has a surface search radar and communications masts which make it unsuited for harbor infiltration but well suited for reasonably clandestine mine laying.

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."

The submarine is said to be a sonar-evading stealth submarine. It is of note that most first-world countries have abandoned diesel engines for their lack of sonar stealth, limited range, and poor longevity. Iranian officials claim the Nahang is equipped with state-of-the-art electronic equipment and can fire missiles and torpedoes simultaneously, but no information was given on the range of these weapons.^[2]
