The contract to build Nooh and Taregh was signed in 1988.^[1] It was reportedly worth $750 million for two submarines, with an option for the third.^[3] Her keel was laid down at Admiralty Shipyard in Saint Petersburg in 1989.^[1] She was launched in 1992 and was commissioned on 6 June 1993.^[1]

The submarine is named after Noah.^[4]

According to Jane's, there is no proof that the submarine has ever returned to Russia for a refit.^[1] As of September 2017, Nooh was under some major repairs by Iranian personnel in the naval factories.^[5]
