TEHRAN (Fars News Agency)- Iran said on Wednesday to have built a submarine equipped with sonar-evading technology, saying the craft had been launched in the Persian Gulf.
The navy chief, Adm. Habibollah Sayyari, was quoted by state television as saying the new Ghadir-class submarine is the second Iranian-built underwater craft outfitted with "state-of-the-art electronic equipment." He said it took 10 years to build.
The report showed a picture of a submarine. Iran's two domestically built submarines can fire missiles and torpedoes simultaneously.
Iran has been pushing an arms development program in recent years in a bid to reach self-sufficiency. It has produced its own jet fighters and armored vehicles as well as radar-avoiding missiles and other high-tech weapons. On Tuesday, it announced a new long-range missile.
Iran has also three diesel-electric Russian made submarines.
Iran's Supreme Leader Ayatollah Ali Khamenei said the new submarine is part of Iran's drive toward self-sufficiency in arms production, the television report said.
"Today, you have been able to design and build many of the military requirements. We have become self-sufficient from other countries," Khamenei was quoted as telling navy commanders Wednesday.
Iranian officials have repeatedly said the Islamic Republic will defend itself should the United States or archrival Israel ever attack.

We’ll have to helicopter Alec Baldwin to investigate this.
Actually, the Swedes did deliver the technology to the U.S. As I understand it, they had one of their subs stationed in San Diego (I think) so our guys could learn to find it. How successful our guys were is probably classified but they’re awfully good, so I should think they have a handle on this new technology already.
I was in Naval Airborne Anti-Submarine Warfare for 7 years. I think I can state with confidence that the Iranians are absolutely full of crap.
Sonar operations in the Persian Gulf, presumably where these subs will operate, are much easier than in the open ocean. Its smaller and quite shallow.
Second, the Iranians don’t have any magic bullet when it comes to sound absorbing materials. You ping something hard enough and you’ll get a return signal. Basically all we have to do it turn up the volume and use the proper audio frequencies.
They’re lying.
I won’t put this out of the realm of possibility, as a Chinese sub did pop up in the middle of a US carrier battle group recently.
as a Chinese sub did pop up was forced to surface in the middle of a US carrier battle group recently
I suspect the Iranians obtained sound absorption or sound isolation technology from the Russians who obtained it from the treasonous Walker family of spies in the USN.
Dear Viewers,
Fars News Agency (FNA) is Iran's leading independent news agency, covering a wide variety of subjects in different, political, economic, cultural, social, legal, sports, military and other areas with the most up-to-date, independent, unbiased and reliable news and reports in Persian and English.
Ever since its establishment in early 2003, it has been making its way towards daily progress and gaining reputation as a trustworthy source of information dissemination by presenting accountable and up to the minute news, reports, analyses, interviews and articles making use of a team of experts who specialize in the field and who have dedicated themselves to the job.
As our English department was established in December 2005 -with the first four months as our test run, we have actually started our official broadcast since March 21st, 2006- we still look forward to receiving feedbacks from our viewers in order to find out which areas they might be more interested in. That's actually why, here in the English department, we are not bringing you an English version of every piece of news, interview, article or analysis our colleagues produce in the Persian department.
Therefore, it is of vital importance and value to us to know which areas our dear English viewers would like us to address more. Thus, we would like to kindly ask you to fill in the "Comments Box" at the bottom of the page, and let us know your views and, if possible, your nationality (at your discretion) to help us minimize possible defects or deficiencies.
If you feel you are interested or need to know the latest and unbiased news from Iran, the Middle East region and the world, please do not hesitate to tour our site at either one of the following addresses:

In other words, this site is approved by the Iranian government, and therefore it is a load of crap.
As for sonar evasion, good luck. No one uses active sonar. An active sonar ping gives away the position of the vessel that did it. Iran may have obtained silencing technology from Russia and China to use for this submarine, but our guys are pretty good, and have the best equipment. I doubt they will admit to their capabilities, but I suspect Iran is well within them.
Even if it is silent, our subs are also silent, and nuclear. This thing is a diesel. It would have to lie in wait for a ship. It could only do so for a couple of days, depending on how much power can be stored in its batteries. It will have to surface and run the engines to exchange air and charge the batteries. When it does, it will be tracked.
Active Sonar is still used a lot and probably every naval ship of ours still has it installed, as well as our subs. Our Navy employs Active Dipping Sonar from helos. This is how we detect enemy subs ahead of the fleet and far outside the range of our passive sonars. Giving away the helo's position is irrelevent since they the enemy subs have no ability to deal with the helo, and the helo is only going to be in that spot for a minute or so and then be gone.
As a side note, these devices (the helo deployed dipping sonar) have been bitten by a sharks during their use. I've seen pictures of R&O units with the teeth still in them. I suspect the sharks don't like us dropping these noise makers next to them.
Not true. After the target is detected and tracked using passive sonar, active is used to give an accurate enough location for weapons deployment. It doesn't matter so much that the target knows it's being pinged when it's about to die.
I hear it’s really quiet until somebody slams the screen door!
Lol I was thinking the same thing.
“This...this could be a caterpillar. Magnetohydrodynamic propulsion, do you follow?”
LOL
"10 years to build."
A lot less time to sink.

Post or FReepmail me if you wish to be enlisted in or discharged from the Navair Pinglist.
This is a medium to low volume pinglist.
Wonder Woman? Izat you?
Where did you ever find that add?
Having been an avid Dave Barry reader for the past 20 years I figured a simple google image search for cardboard submarine would turn it up ... I wasn't disappointed
It is still detectable!
That event you referred to was over a year ago, and we still do not know the circumstances behind it. Nobody is talking about it, us or the Chinese.
Submarines, no matter what navy they belong to, as a rule are LOATHE to surface within sight of a potential adversary. I have never known of an American submarine to do it, ever.
I believe they were forced to the surface.
