Iran launches advanced Jamaran destroyer

:tup:

nice work. it is a shame that the original Chinese missile provided to Iran has a shitty range of 40km. but damn nice to see Iran is capable of upgrading the missile on its own.

Thanks again. The link i provided on the last post talks in detail about all of our anti-ship missiles. Here is a picture of them. The credit for this goes to `planeman`.

 
The FM-80 SAM system is supposed to go where the four holes are in the picture below:

Ohh Yes, my fellow country men don't use their brains that's why we have a 14 Trillion GDP, we are the richest

-Thank You

So when China overtakes your GDP you will concede that your IQ has diminished and that the Chinese are smarter than you?

Please study the history of WW II more closely. You might discover the real reasons why America is the richest and most powerful country in the world today. It has very little to do with high IQ and a lot to do with conditions created by others that America was geographically positioned to exploit. And by the way, historically, the 70-odd year American run is the blink of an eye. The Persian Empire ruled much of the known world over thousands of years. So what if Iran's fortunes took a downward turn for a mere decades, and America's took a turn for the better? 70 years does not history make.

I am a big fan of American ingenuity. But when you dispel the best traits of your people and instead embrace arrogance and hubris, you cut a very, very sorry figure.
 
70 Year down the lane and bankruptcy on the rise now american govt is smarter they wanted war they got several but in return they got what we all witnessed!.

american people or Chinese or Iranian or others there are smart people and lazy ones too never the less there are many who are realizing their mistakes and becoming smart!

When entering terminal phase, the two seeker systems activate, the first is the monopulse active radar...
This is how a monopulse radar works...

Basically...A single signal is split into four and the target is supposed to be inside that shaded area. Less sophisticated ECM will not defeat a monopulse radar but who said the US is one of those 'less sophisticated'?

Article: Deceptive jamming against monopulse radars. - Journal of Electronic Defense | HighBeam Research - FREE trial
This three-part consideration of the deceptive jamming of monopulse radars ends with a discussion of the "cross eye" jamming technique. Several other deceptive techniques remain untreated, but those we have covered are representative. It is important to remember that chaff, decoys and denial jamming are also effective against monopulse radars.

RADAR WARNING RECEIVERS AND DEFENSIVE ELECTRONIC COUNTERMEASURES
Monopulse radars are notoriously difficult to jam and require more cunning techniques such as cross eye jamming. A cross eye jammer employs two deception repeaters which retransmit the impinging radar signal with set time delays. By situating the transmitting antennas at the extremities of the aircraft (eg out on the wings) and manipulating the time delays, the cross-eye jammer distorts the shape (and hence perceived direction) of the returned echo (wavefront). A monopulse track ing system aligns itself with the direction of the incoming return from the target and is thus driven off the target.
There are many other techniques to nullify a monopulse radar. The more sophisticated the electronics and avionics, the more robust and effective the ECM signals. For a monopulse radar, the target MUST remain inside that shaded area and if one of the four receivers is deceived in any way, the monopulse system will believe itself to be out of calibration. The entire system then repeatedly reset itself, rendering the missile useless.

A sharp drop then happens, from 20-30 metres to 5-7 meters above the sea level, maintained by the radio or laser altimeter. This has the advantage of making it near invisible to the target ship because it is below the detection range, especially combined with the integrated jamming capabilities and low radar signature.
AWACS will detect the missile long before it reaches the fleet, probably detect the launch itself.

Third is the introduction of manoeuvring algorithms to make it harder for active ship defences to stop the missile. (9)
Which also limit its maximum range. Maneuvers ALWAYS cost time and fuel.

So as long as the fleet's AWACS detect the missile, in less than five seconds, fleet defense, or even single ship defense for that matter, can launch chaff/flare defenses that will totally blanket the missile's sensors, even before the missile achieve what is called 'horizon break', that is the precise moment when a missile is supposed to catch the first glimpse of the a target. What happens is as the missile is happily cruising along and in an instant, it sees nothing but noise...That moment of detection of that noise is 'horizon break' when it sees something other than ocean surface. Same as if in that same instant it sees the target, which to its computerized mind, the target would look something like this...

All the surfaces and edges on a ship is recreated, hence those squares.

Rafael Anti-Ship Missile Defense System - Decoys
These lightweight chaff rockets are equipped with a programmable electronic timer to generate realistic targets, a few thousand of square meters in size, at ranges between 500 and 2000 meters from the ship.
A few chaff canisters can create an electronic blanket ten or more times the broadside area of a Nimitz class aircraft carrier, totally blinding the missile. Same for flare against IR sensors. So as long as the fleet is covered by AWACS, it will have ample time to deploy these defenses.
 
GREAT PERSIAN NATION ...

What can you add , amazing achivement by Iranian people and desire to be free from some other nation that just like to trool around the world bullying ppl

By the way out of curiosity is it possible for Iran to put a S300 battery on a destroyer ??? Would it still work against Aircrafts ? lets say something like F15 etc
 
Whilst we're on the topic of Iranian Anti-Ship assets, Iran's light attack helicopter, the Shahed 285 can carry two Kowsar missiles. These are the same missiles which knocked out a 1,000+ Ton Israeli corvette armed with the latest defense systems the west has to offer.

Technically it would be possible, but in reality it won't happen.

Firstly, this ship is a light Frigate and not a Destroyer and Iran has no intentions of building large warships in the near future as they have no place in it's "everywhere and no where" naval doctrine. Which is why we are investing a lot of money on Fast attack Craft and Submarines.

All of the naval threats against Iran are confined to the Persian Gulf area and Iran's land launched Anti-ship missiles cover the entire Persian Gulf.

Another reason is that the S300 could be based on Land and it would still cover most of the Persian Gulf.

You can fit the S300 on large destroyers like China does on it's 7,100 ton type 051c destroyer, but not on a 1,420 ton Frigate.
