The Nahang (Whale) is an Iranian built diesel-electric submarine. Its design and construction were said to have involved 220 researchers, and 1.2 million hours of scientific and industrial work. The Nahang submarine, Iran's second homemade submarine, is reportedly one of the country's "largest" defense projects, thought this claim is hard to square with the small number of people involved.
In 2006 the Iranian Navy displayed what it declared to be its first submarine designed and produced without the help of foreign assistance, part of its general goal of military self-sufficiency. "The submarine is fully adapted to the Gulf," Rear Admiral Sajjad Kouchaki said. The submarine, named Nahang (whale in Farsi), is a midget submarine with mockups showing it carrying its armament (primarily mines) externally to save space. Iranian authorities also described the Nahang as having an anti-ship missile capability, though it was unclear at the time how such an arrangement would be achieved on the small craft.
With an estimated displacment of a few hundred tons, The Nahang class is a true mini-sub, carrying its weapons externally, being too small for internal torpedo tubes. By one report Iranian TV images of a computer generated simulation appear to show mines attached below the side bulges. The Nahong does have a surface search radar and communications masts which make well suited to clandestine mine laying, with possibly a limited capability to mount ambush torpedo attacks.
The Nahang 1 has a surface search radar and communications masts, which make it unsuitable for harbor infiltration, but good for reasonably clandestine mine-laying. It is said to be a sonar-evading stealth submarine. 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. Nahang means "whale" in Persian.
