Hoot Iranian Sub-surface high speed torpedo

I thought this amazing torpedo definitely deserves its own thread for discussion and photos.

Here is a classified but exposed technical report on this torpedo:

Any references in the document about a possible guidance or homing system? Or is it unguided as the original Soviet VA-111 was?

Any references in the document about a possible guidance or homing system? Or is it unguided as the original Soviet VA-111 was?
Early VA-111 Shkval Missiles Was Guided by Inertial guidance system and upgraded models have Teminal Guidance System

It is possible that Hoot is also Using Termnial guidance

Definitely Hoot and Shkval are Fantastic missiles . Using Supercavitation Technology , These missiles can reach 100m/s (250+ knots) speed which exceeds that of any standard torpedo currently fielded by NATO. Only Iran and russia has this technology.

a major Advantage of using Supercavitation tech in torpedos Is Minimizing Water friction , the VA-111 Shkval (or hoot) missile Creates a Air Bubble Around the whole missile with it's nose cone in underwater Phase . Thus , Shkval missile Practically has a equal friction with a missile traveling in Air while Travelling underwater .

Stalin,

I actually know a good deal about the VA-111 which is why I asked if the article made any mention to a real guidance system.

Inertial guidance is hardly a real guidance system. This means that once fired the torpedo simply moves in a straight line. This is largely why the early variants of the VA-111 only had a range of a few kilometers at best which is a fracture of the range of traditional torpedo. This in turn means the vessel carrying the torpedo would have to get quite close to the enemy vessel undetected and preferrably be used against a rather unmanueverable target.

For all these reasons the original VA-111 was designed to carry a small nuclear warhead to make up for its lack of true guidance and short range.

Now the problem with trying to make such a torpedo more accurate is you have to change the steering system used by the torpedo. This is because the torpedo moves too fast for its small fins to properly allow the torpedo to manuever other than in a straight line. To solve this, the Russians are believed to have added a Thrust Vectoring system of some sort.

While its possible the Hoot has such a steering system, it is impossible at this point to confirm unless there is something mentioned in the article posted by Catsoo.

Although inertial Guidance is Very Different from UnGuided (!!), I agree early VA-111 models had inacurrate Guidance system , But As i said , Later models that have Terminal guidance which Increased their Range to 13 kilometers .

with note to this fact that Iran has introduced it's Domestic "Hoot" missile Just 4 years ago , It is Very probable that Hoot missile is Reverse-engineered from upgraded Shkval models and thus , it probably has the Terminal Guidance system , Although the document brought by Catsoo it is only Tests on Hoot's Motor and Cavitation system , Not mentioned anything about guidance system .

anyway , the fact is This Speedy missile is a very dangarous Anti ship weapon And No ship can evade form it ! (neither Inertial guided or Terminal guided)

What are different Anti Ship Iran Domestic HOOT and Rusian VA-111?

Mashallah.

While it is not nice to see classified military-industrial documents from Iran being leaked to the enemy's information centers (like "FAS.org"), in this case, it proves that Iran possesses the technology and ability to produce super-cavitating highspeed rocket-torpedos. And the document seems not to reveal much about important details such as its guidance systems, but is sufficient to indicate Iran produces such a weapon - which in turn leads to the hypothesis that Iran might have leaked the paper itself, in order to put an end to the anti-Iran intoxication in the western media, which were stipulating that the Islamic Republic "cannot" produce Shkval weapons system equivalents; at the same time, the enemy is kept in the dark regarding specific details. 

It always amazes me how much nerve and how little shame the anti-Iran propagandists have... I remember when Iran first revealed the Hoot torpedo, US / zionist military propagandists reacted by shedding doubt on the authenticity of the news, and tried to portray Iran as technologically and industrially "incapable" of such a feat. They even suggested that a video sequence released by IRIB, showing a Hoot launch, would in fact have been an old Chinese PLA video.

Now that evidence has emerged Iran does possess and mass-produce the weapon, and that previous "arguments" denying this fact were shown to be fraudulent and fallascious, US / zionist propaganda adapted itself to the undeniable reality, and adopted a new discourse: the new Pentagon / CIA / Mossad propaganda line regarding Hoot, is that while Iran does produce the weapon, the latter would not be really useful in combat. Articles are published by US "naval defence experts" suggesting how "easy" it would be for targetted vessels to simply outmanoeuver the Hoot, or use other countermeasures to neutralize it; also, the focus is placed on suggesting that the launch platform of the Hoot, due to the weapon's limited range, would "not" stand a chance of approaching US vessels enough to succesfully target them (I read one such article recently, and will post the reference if I find it).

Which of course is speculative nonsense, as Iran's Ya Mahdi stealthy FAC as well as its stealthy semi-submersibles, in a real conflict situation in the Persian Gulf, do actually stand a brilliant chance of slipping through the enemy's surveillance net and radars to get into firing range. The Hoot is a major asset in Iran's naval defence, and the enemy is trying to underrate its power so to maintain the morale of its own troops, knowing that fighting spirit in NATO armies is very low, specially against capable adversaries such as Islamic Iran.

Hoot torpedo

Hello to all of you!
I'm new in the forum. I've been reading it for a time, and now I've registered.

I'm very surprised about the military industry of Iran. I've realized the fact that Iran has been forced to develop a native military industry since the revolution succeeded.

One of the things impacts on me most, is the supercavitation thorpedo, the Hoot. I would like to know a little more about it. I've read it's an reverse engineered thorpedo from the russian Shkval. Does Iran have a sufficient number of it to engage a potential naval strike from the 5th fleet?

Also, I would like to know if there are countermeasures for this kind of thorpedos. I know the AEGIS, but AEGIS is developed for AA defense. In the case of a submarine attack (with thorpedos), what kind of defences does an AEGIS ship have??

Thanks you all!!  ;)

Hello and welcome to the IMF.

You should read the new article on globalresearch:

The Geo-Politics of the Strait of Hormuz: Could the U.S. Navy be defeated by Iran in the Persian Gulf?

And maybe follow the current dicussion on IMF here:
