Iranian Torpedos?

TEHRAN, Iran - Iran said it successfully tested another new torpedo Monday, the latest weapon unveiled during war games in the Gulf.

The torpedo can target submarines at any depth and is powerful enough to "break a heavy warship" in two, a spokesman for Iran's Revolutionary Guards, Gen. Mohammad Ebrahim Dehghani, told state television. He did not announce the name of the new torpedo or give details on its speed or range.

On Sunday, Iran announced it had tested a different torpedo, the new high-speed "Hoot," which means "whale." It moves at up to 223 mph, and Iran said it was too fast for any enemy ship to elude.

On Friday, Iran tested the Fjr-3, a missile that can avoid radar and hit several targets simultaneously using multiple warheads.

The Revolutionary Guards, the elite force of Iran's military, have been holding their maneuvers — code-named "Great Prophet" — since Friday, touting what they call domestically built technological advances in their armed forces.

223 mph? Underwater? I call bullshite.

Imagine the B.O. stench inside that Iranian submarine. They could probably just surface, open the hatch, and use fans to blow the noxious gasses toward an enemy and get an immediate surrender.

Couldn't a ship employ a steel mesh net to interfere with incoming torpedos? Gotta be better than taking a direct hit.

They have the most warped sense of reality over there. They think that just b/c their citizens are too stupid to realize that bullshit they feed them, that the rest of the world will believe anything they say.

Where's Mike the Lab Rat or somebody else with a science background? There must a limit as to how fast an object can travel underwater.

I used to barefoot waterski and because of friction, the water used to feel like it was burning your feet at about 43 mph.

I didn't know Iran even had a navy.

[PSUFAN]

I have a feeling that when someone lights a match in East Tehran, we're going to hear about it.

[Mikey]

45 to 50 knots is generally accepted as the top speed, unles it's a Russian rocket powered torpedo...

Super. Both Iran and America will continue to posture until they have to have a war just to save face.


Goddammned retards.

What's the range on one of those things?

Didn’t they reveal that they now have have some sort of revolutionary stealth missile that could hit multiple targets a few days ago...?

They are on a roll...

Second.

They're getting scared.

Y'know, mvscal, every time you type shit like that, I know you see yourself as Henry Blofeld stroking a white cat. When in reality, you're sitting on an old beer crate, violently masturbating, whle the drool bubbles around your ignorant maw.

[Mikey]

SHKUAL! is the sound the Kursk made as it exploded.

Didn't Earl Campbell do an add for that nasty shit back in the 80's



Wait a minute, here it is..



"SHKUAL, brotha!!"

I'm thinking the speed of light is the limit for speed underwater.

Al?

Harpoons are pretty much useless against a diesel sub. sayin.

I'm no submarine expert and I didn't even stay at that hotel that's 'sposed to make you smart, but, I am in a submarine type reserve unit chock full of fukkers that have been there and done that aboard a sub. So, from being around these fukkers I have learned a thing or two about subs.

So, here's the problem with a torpedo running at Daytona type speeds.

Going fast underwater is noisy. If you are noisy, you won't be able to hear your target AND your target will sure as hell hear you. So, even if Iran or Russia for that matter can build a fish that will move that fast, it won't be able to track shit. And if it can't track shit, it is worthless unless they actually are dumb enough to put a nuke on it.

And if they are that dumb, good. Then it is game fukking on. And we can vaporize those mutherfukkers cause we actually do have nukes and unlike them, our ability to deliver them is not just a news story.

One other thing. The persian gulf is a shallow pond. Submariners hate going there because they can't hide very well. I am fairly certain that we have a pretty damn good idea where every last POS Iranian sub is in the gulf. And if they start making threatening gestures with said boats. I'm guessing that we will blast one of them clear out of the water just to let them know how badly they suck at this game.

Hey. This is a "countermeasure" we hadn't considered.

Sin,
Iran


Any half-assed military who thinks the USA can't come up with a "countermeasure" isn't thinking very clearly.

[Uncle Fester]

I don't understand how it's possible for a physical object to go that fast underwater, especially in seawater, which is more dense than freshwater.

Maybe that will help.

[Y2K]

Give these fuckers a break!
They sunk a standing derilect ship with their superweapon.
This was certainly a step up from all the time they have missed it.
I am convinced they have pure superiority in all the worlds waterways.
Be Afraid.

Sensors indicate that Mr. Scott is indeed correct: You cannot change the laws of physics.

My bad:
From Popular Science:

Submarines peaked in power and relevance during the Cold War; there has since been a shift in focus to aircraft-based combat, and subs have become budget-cut victims. But subs are still prized for their ability to sneak about global waters undetected and to defend surface ships from attack. Many U.S. subs are being converted from missile launchers into delivery vehicles for special operations troops.

But the supercavitating torpedo—a rocket-propelled weapon that speeds through the water enveloped in a nearly frictionless air bubble—may render obsolete the old submarine strategy of sly maneuvering and silent running to evade the enemy. The superfast torpedo could be outfitted with conventional explosive warheads, nuclear tips or nothing at all—a 5,000-pound, 230-mph missile could do enough damage on its own. The Russians invented the concept during the Cold War, and their version of this underwater killer—dubbed the Shkval (“Squall”)—has recently been made available on the international weapons market; the United States, of course, wants a new, improved version of the original.

The hard part about building a rocket-propelled torpedo isn’t so much the propulsion as clearing a path through the ocean. Water creates speed-sapping drag; the best way to overcome that drag is to create a bubble that envelops the torpedo—a supercavity. A gas ejected uniformly and with enough force through a cavitator in the nose of the torpedo will provide such a bubble, permitting speeds of more than 200 mph and a range of up to 5 miles (traditional torpedoes have slightly longer ranges, but lumber at only 30 to 40 mph). Though submerged, the torpedo remains essentially dry, with a frictionless surface. “That sounds easy, but doing it is extremely difficult, especially if you’re trying to steer,” says Kam Ng, program manager for the torpedo at the Office of Naval Research, which has been developing the weapon since 1997. “If your torpedo moves in a straight line, you just aim and shoot,” says Ng. “That capability already exists with Shkval. But the U.S. vehicle will be more capable—it will turn, identify objects, and home in on the target.” (Improvements to the torpedo to make it steerable likely froze when the Soviet Union collapsed, says GlobalSecurity.org’s Pike.)

Among the greatest challenges for U.S. torpedo researchers is developing detection and homing technology that will enable the torpedo to distinguish an enemy sub from, say, a rock formation, says Ng. Also tricky is finding a way to control the gas bubble to permit those course changes. “When you turn, the bubble distorts because it is no longer symmetrical,” he says. “So you have to compensate for that by putting more bubble to one side.” This is done, Ng explains, by ejecting more gas toward the outside of the turn.

Naval officials say the high-speed torpedo will enable submarines to attack enemy subs and surface ships without giving them time to respond. The U.S. military has tested a prototype, but combat-ready versions are not expected for at least 15 years.

Also disturbing is the fact that the Iranians, by answering some of the ads in the back of Popular Science, could learn to build their own folding kayaks and become locksmiths in their spare time.

Can an Iranian build a WMD from a used "chipped" Scientific Atlanta Cable TV Box or will he use it only to steal Pay Per Porn ,WWE and boxing?

If one Iranian left tehran on a submarine headed west at 7am camel jockey time ,and another Iranian left on the back of a dung beetle at 10am camel jockey time, which would be the first to deplo........

Dammit Fester, I'm a biologist, not a physicist!

[Jerkovich]

I don't understand how it's possible for a physical object to go that fast underwater, especially in seawater, which is more dense than freshwater.

Read the technical notes. It creats it's own bounder layer with air ducts in the front cone. This makes it travel though the air generated and the water is displaced around the missile.

Ask Din, he'll fill you in on the rest of the technical stuff.

Of course you're referring to Rove's fake news department?


(How dare you use the nic of Cicero, the great orator?)

[titlover]

I don't understand

I stopped reading.

[smackaholic]

even though that ruskkie torpedo is flying through a layer of bubbles, it created, that doesn't change the fact that it's still gotta push a lot of water out of the way in a hurry. and it is extremely noisy. so, i guess it might be somewhat effective against a large surface ship, but, there is no way in hell it would make an effective ASW (anti sub warfare) weapon.

[silvurna]

Detecting the torpedo using sonar receptors wouldn't be much of a problem, agreed. it's a noisy bastard. If it was possible to maintain that high velocity, and make it a silent run, other detection would have to be done using towed array sonobuoys that detect changes in magnetic fields or in an extreme cases, an aircraft that will detect infrared signatures. These last two methods seem somewhat unlikely because of the short distance involved.
Hanging an anti-torpedo net over the sides of a ship involves a lot of excess superstructure and thus weight. Maintaining the stability of nets like that when a ship is underway would be problematic. The other issue with the net is that the 'weave' must be smaller than the diameter of the torpedo, and as such, the net would soon become. unmanageably heavy since it would trap seaweed, dolphins/larger fish and pieces of Natalee Holoway.

[smackaholic]

First off, a sonobuoy doesn't detect magnetic fields, a MAD boom does. It works pretty well with aircraft because you can hang the boom below the craft where it's own magnetic field doesn't bother it. This don't work too good with surface/sub crafts.

Secondly, everybody knows Natalee is in the dunes. Don't you get any news.

Air displaces water very efficiently.....and as far as the noise...well, the only command you get out of your mouth would be .."ah shiiitttt"......BOOOMMMM!

[silvurna]

it's a noisy bastard.

Which is totally irrelevant when it is moving over 200 miles an hour and tipped with a nuclear warhead which was the Soviet concept.

Thus my mention of the short distances involved.

Yes I do, and until I read or hear the news that her body was found in a dune, I don't know for certain where she is. If you do, go help dig her up.

actually the MAD booms are fixed to the aircraft themselves. and you have to do a MAD comp flight to cancel out airplane noise. those suck ass. :wink:
