جزئیات جدیدترین زیردریایی ایرانی با نام "فاتح"

خبرگزاری فارس: جدیدترین زیردریایی بومی با نام "فاتح" به منظور حفاظت از منافع دریایی جمهوری اسلامی، بزودی به ناوگان ارتش افزوده خواهد شد.
خبرگزاری فارس: جزئیات جدیدترین زیردریایی ایرانی با نام "فاتح"

به گزارش خبرنگار دفاعی خبرگزاری فارس، الحاق 4 فروند زیردریایی سبک کلاس غدیر به ناوگان دریایی ارتش جمهوری اسلامی ایران در مرداد ماه سال جاری، علاوه بر تقویت توان حفاظت از آبهای سرزمینی جمهوری اسلامی، مهر تاییدی بود بر توان متخصصان صنایع دفاعی کشور بر طراحی و ساخت پیچیده ترین سامانه دفاعی که برخی تکنولوژی آن را از ساخت جنگنده نیز مشکلتر می دانند.

اهمیت استفاده از زیرسطحی ها در حفاظت از آبهای سرزمین و منافع کشور در آبهای آزاد به گونه ای بود که در سال جاری برای اولین بار زیرسطحی سنگین ارتش با نام "یونس"، به منظور نشان دادن اقتدار دریایی ایران با گذر از آبراه‌های بین المللی، وارد دریای سرخ شد.

از این طرف با توجه به عملیاتی بودن بیش از 10 فروند زیردریایی کلاس غدیر در آب های خلیج همیشه فارس، که توانایی اجرای عملیات در آب های کم عمق و امکان پایین شناسایی شدن را دارند، امکان اعزام واحدهای زیرسطحی کیلو به عملیات فرامنطقه ای، بدون به خطر افتادن توان زیرسطحی کشور در منطقه فراهم شده است.

در واقع پس از ساخت زیردریایی‌های مختلفی چون نهنگ، زیردریایی سبک از کلاس غدیر با تلاش چندساله متخصصان وزارت دفاع به گونه ای طراحی و ساخته شد که این زیردریایی ها کاربرد وسیعی در منطقه دریایی خلیج فارس داشته باشند.

چابکی لازم برای انجام سریع مأموریت‌ها، رنج ناوبری زیر سطحی طولانی، سونار سایز کوچک، دستگاه کنترل عمق اتوماتیک، سیستم هدایت دستی، هیدرولیک و خودکار، قابلیت ناوبری در آب‌های کم عمق، از دیگر ویژگی‌های زیردریایی کلاس غدیر است.

اما با توجه به اینکه اصول و تاکتیک‌های ساخت شناورهای زیرسطحی عمدتاً مشابه و یکسان است، جا داشت تا با طراحی و ساخت زیرسطحی های نیمه سنگین توان حفاظت از آبهای سرزمینی جمهوری اسلانی ایران هرچه بیشتر افزایش یابد.

همین امر باعث شد تا متخصان صنایع دفاعی کشور با اتکا به تجارت گذشته خود در طراحی و ساخته سامانه های زیر سطحی، ساخت جدیدترین زیرسطحی نیمه سنگین جهوری اسلامی ایران با نام "فاتح" را در دستور کار قرار دهند.

زیرسطحی "فاتح" با تناژ حدود 600 تن جزو زیرسطحی‌های نیمه سنگین ارتش جمهوری اسلامی ایران محسوب می شود که به احتمال زیاد در ماموریت‌هایی نظیر حفاظت از آبهای سرزمینی در کنار دیگر زیرسطحی‌های نیروی دریایی مانند زیر سطحی "غدیر" به انجام ماموریت خواهد پرداخت.

این زیر سطحی مجهز به پیشرفته‌ترین تسلیحات دفاعی و تهاجمی ازجمله چندین اژدر و مین‌های دریایی است که می تواند در عمق عملیاتی بیش از 200 متر در مدت زمان تقریبا 5 هفته به حفاظت از آب‌های سرزمینی ایران اسلامی بپردازد.

بکارگیری انواع زیردریایی‌های سبک، نیمه‌سبک و سنگین در سازمان رزم نیروی دریایی، نقش بسزایی در ایجاد یک نیروی دریایی راهبردی به منظور حفاظت ار منافع ایران در آبهای آزاد و بین‌المللی و نیز حفاظت از ‌بهای سرزمینی ایفا خواهد کرد.

Someone said if this new subs can house Iran's SSM's . That is are they deep enough . I think the answer was no ! The height of existing missiles with long range too tall . I thought if it possible to house the SSM's at an angle ! Slightly sideways . This way they will fit . Also pushing them out under the water should not be a problem . The missile when exit the sub can correct itself and become vertical again and exit water with correct angle . The only modification to missile is make it waterproof and have steam ejection system . Existing subs may also be modified to carry long range SSM's in this way .

Also to make this easier (firing missile out of slanted tube ) the sub can point it's nose up underwater , to compensate even more . It may even be possible to launch missile in upright position underwater . With a little practice .

Another extreme solution is to allow sub to carry SSM's like torpaedoes in a horizontal fashion . (perfect fit for 4 SSM's ? ) but allow sub to assume vertical position for firing .Or even more extreme is to fire like torpaedo and allow missile to correct itself .

Compare Sejjil to Polaris . Polaris is a short and fat missile able to sit vertical inside sub . This reduce it's range . I think they did this to allow max number of missile to be carried by sub . But is one sub carrying 16 missile better than four sub carry 16 missile ? Also it looks natural to allow for long slender missiles and house them horizontal inside sub . Can sub assume a vertical position ? Then a solution is found . It may even be possible to allow tip of sub to come out of water and allow for dry firing ! Alternatively a horizontal underwater firing may have to be deeper than Polaris or Trident . Because size of missile . But it can be done . Eject missile from 30 ~ 40 m depth . Allow missile to slowly become vertical by fixing buoyancy aid to tip like disposable air filled tanks ( while bottom of missile is still connected to sub body by cable ) . Once in vertical position release the cable and use rocket like the skhval to push upward with speed . This should give longer rocket enough speed to clear the water . Then eject booster and buoyancy tanks .

Iran to Unveil New Submarine

TEHRAN (FNA)- Sources revealed on Wednesday that Iran is building a new semi-heavy submarine equipped with highly advanced weapons.

The submarine called 'Fateh' (Victor) weighs 600 tons and is equipped with various types of advanced defense systems and weapons, including several kinds of torpedoes and sea mines.

According to FNA sources, Fateh which will launch operation for the Iranian Navy in coming weeks will be tasked with patrolling Iran's territorial waters and protecting the country's interests in the high seas and international waters.

The submarine can dive to the depth of 200m and continue voyage for 5 weeks.

The vessel has been fully designed and manufactured by Iranian experts and enjoys state of the art technologies.

Late last month, Deputy Commander of the Iranian Navy for Research and Self-sufficiency Jihad Capitan Mansour Maqsoudlou announced that the Iranian Navy has a major development plan, dubbed as Velayat (religious leadership), and said manufacturing vessels and submarines of different class and type is on the agenda of the Navy based on the plan.

Iran's Navy Commander Habibollah Sayyari announced in July that an Iranian submarine, called 'Younes', had completed an inaugural mission in the Southern Indian Ocean and the Red Sea.

Also, Iranian Navy Deputy Commander Rear Admiral Seyed Mahmoud Moussavi announced in mid June that the country plans to equip its Navy with new types of home-made submarines as part of its naval units renovation plan.

"The new submarines, built by the committed Iranian experts, will join the naval combat fleet," after being tested during upcoming military exercises, he said.

The drills will test the capabilities and efficiencies of the new submarines, he further explained.

Rear Admiral Moussavi went on to say that the country's naval force seeks to diversify the maneuvers in order to enhance its defense potential.

To achieve this aim, Iran's Navy is ready to hold joint drills with neighboring countries, he pointed out.

Tehran launched an arms development program during the 1980-88 Iraqi imposed war on Iran, to compensate for a US weapons embargo. Since 1992, Iran has produced its own tanks, armored personnel carriers, missiles and fighter planes.

Yet, Iranian officials have always stressed that the country's military and arms programs serve defensive purposes and should not be perceived as a threat to any other country.

Last August Iran launched four light and advanced submarines. The Ghadir-class submarines, made by the Defense Ministry's Marine Industries, officially joined Iran's naval fleet in an official ceremony attended by Iranian Defense Minister Brigadier General Ahmad Vahidi and Commander of the Army's Navy Rear Admiral Habibollah Sayyari.

Iran announced in June 2009 that a home-made submarine, named Ghadir 948, had joined the naval brigade of the first naval zone.

In November 2009, Iran announced that its first domestically built Ghadir class submarine launched operation.

The Iranian military said that the submarine can easily evade detection as it is equipped with sonar-evading technology and can fire missiles and torpedoes simultaneously.

initial announced date for launching Ghaem submarine was next year in summer.

I guess it has been done during supreme leader visit to Bandar Abbas.
In recent years Iran has launched 4 new Ghadir at end of spring or early and middle of summer, every year.

This year I was waited for launching new ghadirs this summer but there was no officially announcment for it, so I guess maybe they want to keep secret number of their Ghadir submarines.

M-ATF · « **Reply #5 on:** October 05, 2011, 06:05:26 PM »

I think now Iran has around 15 Ghadir submarines.

I agree! I am most curious to see what this sub looks like! I posted a photo of a similar size sub few tears back that the US Naval research (without giving me a credit) used it in one of their publications. I want to know if Fateh looks similar to that photo or not!

Catsoo,

I remember that image, it's actually all over the net these days and rarely does the poster ever give you the credit for the image.

The image in question, is almost identical to a Russian small coastal patrol submarine concept called the "P-550" which would have a displacement of roughly 600 tons. I was always a bit suspicious about how likely it would be for that concept to see the light of day considering it's origins (wouldn't think the Russians would give Iran the 'blueprints' for a concept they never built themselves). IF this is what the "Fateh" will be then that will be a very interesting event indeed.

For more information on the P-550 concept, see my thread from a year or so ago called "A Tale of Two Submarines":
http://www.iranmilitaryforum.net/index.php?topic=2695.msg43527#msg43527

Eagle2009 · « **Reply #8 on:** October 05, 2011, 07:15:55 PM »

Here are the specifications for the P-550 Submarine concept I am talking about:

Displacement- 650 tons
Length- 51 meters
Max. Diving Depth- 300 meters
Max. Underwater Speed- 16 knots
Max. Range- 2500 miles
Max. Endurance- 20 days
Complement- 9 + 6 combat swimmers
Armament- 4 x 533mm torpedo tubes (capable of carrying 4 torpedo and/or cruise missiles)
- 12 mines

Notice there are some differences with what Iran has stated about the "Fateh" and the P-550. While they are of similar size, the Russian submarine concept claims to have a crush depth of 300 meters instead of the Fateh's 200 meters (which is still a good crush depth for a submarine of that size). Another difference is the endurance of only 20 days compared to the Fateh's 35 days.

IF the two concepts are related, I suspect the crush depth difference might be that the Russians probably intended the use of Titanium in the hull construction whereas Iran doesn't have that much access or experience with using that particular metal. This would also explain the Fateh's being lighter. The difference in endurance is anyone's guess though. It's possible Iran may have removed the space for divers alloted by the Russians for additional fuel but whether it can increase the endurance by two weeks I have no clue.

DarkOmen · « **Reply #9 on:** October 05, 2011, 07:21:32 PM »

so how do you guys think these subs would perform in the PG? I would think the shallow waters of the PG would be ideal for these subs. Also how would these sub effect the balance of the currant naval situation in the PG?

Catsoo · « **Reply #10 on:** October 05, 2011, 07:45:40 PM »

Eagle,

The similarities are strikingly close.What I am wondering is that there was another submarine model that was shown to public that looked different than the one in my photo. It was all black in color.

I am very curious to see what is Fateh!

Eagle2009 · « **Reply #11 on:** October 05, 2011, 08:30:15 PM »

Catsoo,

I know the model your talking about, it was the other submarine in the "Tale of Two Subs" thread I started.

However IMHO, that submarine concept is likely a larger design in the 1000+ tons range because of how it is proportioned. And that concept is also likely indigenous to Iran whereas this could be based on a Russian concept (which is why the P-550 like concept looks more modern than the other Iranian submarine concept).

Nice to finally see the launch of the Qaem class. Been very much looking forward to it for some time. Never knew about it being based on the original Russian design. Great info everyone.

How many will we get?

also how advanced are they compared to the ones usa and zionist whores subs?

Chacko-T · « **Reply #15 on:** October 09, 2011, 10:15:37 AM »

I call this Russian design is a complete BS. Tell me one case when the Russians handed over the blueprints to Iran...
I think it could be the North Korean Sang-O class, maybe in a slightly enlarged version.

Ayyash · « **Reply #16 on:** October 09, 2011, 03:47:23 PM »

It would have to be a fair bit bigger then the original Sang-O since the estimates I've seen put its displacement at ~370 t. I realize that specifications are not always an exact science and can vary according to your source, but 230 tons is still a lot of difference.

Nightstrike · « **Reply #20 on:** November 27, 2011, 08:32:31 PM »

I can see a layered approach to Iranian subs, an arsenal of 30-40 midget subs would prove lethal in the shallow waters near Iranian coastline. At the same time expect to see subs with a longer range to create a stronger presence out of the PG.

They said everything was going to be done from sub . The sub has more survivability than surface ship . If it is quiet .

Iranian made dry submarines

1- Ghadir 110 tons

2- Nahang

maybe 250-300 tons there is a picture and a video clip of this

3- Fateh 550 tons

4- Ghaem 1200 tons

5- Besat

?

cool info here

http://www.mashreghnews.ir/fa/news/78281/زیردریایی-فاتح-قاتل-خاموش-ایرانی

Fateh is 4.5 times bigger than ghadir and 4.5 times lighter than kilo class

Fateh at 23% of kilo weight has about 75% of kilo class capability.

PERSPOLIS · « **Reply #24 on:** November 28, 2011, 02:22:36 AM »

here is some persian text about another one called Besat

I think this is the same as Ghaem

در کنار ساخت زیردریایی های کوچک مانند نهنگ و همچنین زیردریای های مرطوب مانند السابحات برای طراحی و ساخت زیردریایی های بزرگتر نیز اقدام شد که تا کنون از دو نمونه در رده های وزنی حدود 500 و حدود 1000 تن صحبت شده است. این زیردریایی ها که به نظر می رسد همان زیردریایی های فاتح و بعثت باشند که اخیراً توسط یکی از معاونان نداجا نام برده شد در واقع انقلابی علمی در عرصه صنایع دریایی کشور را نوید می دهند که در اینجا به معرفی زیردریایی فاتح می پردازیم.
زیرسطحی 527 تنی فاتح به عنوان یک زیردریایی نیمه سنگین تلقی شده و تناژ آن در زیرسطح نیز 593 تن است. این زیردریایی از نظر مشخصات عملیاتی بسیار برتر از غدیر بوده و توانایی حرکت در عمق 200 متر را به صورت عادی داشته و بیشینه عمق قابل دستیابی برای آن نیز 250 متر است.
