“…if an ordinary submarine can sit in the Persian Gulf’s bed it would be the worst threat to the enemy. That is one of the U.S. concerns since Iranian submarines are noiseless and can easily evade detection as they are equipped with the sonar evading technology…When the submarine sits on the seabed it can easily target and hit an aircraft carrier traversing in the nearby region.”-Rear Admiral Farhad Amiri

February 9, 2012, Iran announced it has completed two more high tech attack mini submarines, designed to patrol the Persian Gulf.  They claim the submarines are 100% built in Iran.

The Ghadir class mini submarines are small (some say they look like a submarine made by North Korea), and can fire Hoot supercavitating rocket powered torpedoes, which are far too fast for a ship to avoid.  Those torpedoes could be based on the Soviet rocket torpedoes developed during the Cold War.

The latest subs will join at least three other subs that were completed in 2009.  Here’s pics of them.  Iran has not revealed how many of the mini subs they have, but USAToday estimates they have 12 mini subs (and three big Russian designed submarines).
