An excellent piece of work my friend.sorry, but once again I wanted to do some "updates" to Sahand 74 with photoshop,
Fateh is an incredible submarine. As IRIN commander said It has basically the capability of a large tactical submarine but in a 600 ton submarine. Few points to note:
Admiral Khanzadi stated that Fateh submarine uses 360 degree sonar systems. Meaning instead of having just one sonar fixed in the front etc, it has multiple sonar systems scattered throughout.
He also talked about the use of smart sea mines. These mines can be controlled and guided from the Fateh from a distance. These mines are programmed to identify enemy ships based their acoustic signature and then detonate. In other words, you can plant these mines and then our own ships can be safe. He said they have a bank where they have gathered and hold these acoustic signatures of enemy vessels.
Range of Valfajr torpedo has been doubled.
Regarding Mohandes longe range Anti cruise cruise missile, he stated this missile is programable and allows it to be fired in a manner to attack the targets from positions they're not expecting, i.e from behind.
