Service History
Shortly after the acquisition of TAREGH by Iran, the American submarine USS TOPEKA (SSN-754) entered the Persian Gulf in order to monitor TAREQH, while its declared mission was "routine maintenance".[3]

According to Jane's, there is no proof that the submarine has ever returned to Russia for a refit. However, following negotiations for an upgrade, a refit began inside Iran in mid 2000s reportedly with the assistance of Rosoboronexport and Sevmash. Ever since Iran is able to refit Kilo-class submarines on its own.

TAREGH fired electrically propelled torpedoes for the first time in December 2011, during a war game named Velayat-90.

In May 2012, Iran announced that it had relaunched TAREGH after an overhaul in which some 18,000 components, including radar-evading cover, engine parts, propellers, and radars were replaced. In the ceremony to rejoin the service, Admiral Habibollah Sayyari said the Russians did not provide Iran with any "instructions on submarine's details and structure", adding that his men had to figure out everything themselves.

In September 2012, it was deployed in the Persian Gulf as a response to the naval drills led by the United States Navy's Fifth Fleet, before being fielded in Velayat-91 exercise for a test of its new armaments. The war game lasted from December 2012 to January 2013 in the Arabian Sea.[9]

In January 2015, TAREGH left home on a mission to provide security for shipping lines sailing from the northern parts of the Indian Ocean to the Strait of Malacca and then the South China Sea.[2] Almost a year later, the submarine took part in the wargame Velayat-94, sailing as far afield as the Sea of Oman and the northern Indian Ocean.[10] In November 2016, General Ataollah Salehi declared that Taregh is ready for dispatch as far as the Atlantic Ocean.

Media reports indicate that as of February 2019, Iran has upgraded TAREGH to fire submarine-launched cruise missiles.
