New Pictures of Sahand Frigate

Iran is self sufficient in Radar technology and Electronics , whatever they may display in public might only be tip of the iceberg

• Iran should may be do a barter trade with North Korea
  
• Aquire Frigate ships from North Korea , and exchange food & cars and food products

3,000 tons and its SAMs are a few MANPADS

Regardless, it would be disappointing if the Sahand had the old lattice mast.

UMS Kyan Sittha: yes, it is lacking in the area of SAM. Still, the speed at which newcomer (in naval design and engineering) Myanmar is developing larg(er) modern designs is impressive. And lets not pretend that 4 × Mehrab of Fajr Missiles (reverse engineering of SM-1) is impressive AAW for a 1500 ton ship: it may be a larger missile and have longer range but the number carried is quite small, the launchers cannot be rearmed while at sea (so, after 4 shots its back to port) and the requires target radar illumination (i.e. limited to 1 target at a time). Good MANPADS can be fired at a higher rate, IR homing allows for engagement of more targets in quick succession (fire and forget), launcher can be reloaded quickly, and more spare rounds can easily be carrier onboard.

2500 ton Aung Zeya is single ship class, a one-off ship, which was probably intended to test integration of various weapons and systems of the subsequent 3000 ton Kyan Sittha. Indian design and engineering assistance on these ships. Is also apparent in 1,105 ton Anawratha class corvette (some resemblance to Kamorta class)

It's written on it "Satellite antenna" ...

Satellite communication antenna and Satillite TV antenna both have the words 'satellite' and 'antenna' in them. What is the exact wording of the handwritten text?

That's Iran's 2nd Mowj Class called Damavand

Iran's Sahand will be more capable with reduce RCS

And the one after that will come out a few months later will be even more impressive!

Iranian Mowj Class are more powerful and far better armed they have Anti Aircraft Missiles, Larger Cannons, more advanced anti ship missiles, torpedo's, far more advance countermeasures, electronics, sensors & communication systems. And unless your radars are all passive then what's the point of having a reduced RCS Haul?

RCS on the Sahand will be less than Damavand but overall Iranian ships are far more capable!

Also, building the body and hauls of the ship is the easiest part. Iran can build Mowj Class hauls in under in under 2 years.

What Iran should be interested in as it pertains to N.Korea is the Sinpo Class Submarine and not just in buying it but also in a tech transfer for a 2000 tone sub with a range of 3000km capable of firing Ballistic missiles & Torpedo's!
And I'm sure will be willing to give N.Korea far more than Food and Fuel for it!!!!!! And the N.Korea's despite the rhetoric aren't starving and going hunger!!!!!






Ships that size you will not be able to reduce RCS

New North Korean corvettes spotted
Gabriel Dominguez, London and Sean O'Connor, Indianapolis and Neil Gibson, London - IHS Jane's Defence Weekly
11 November 2016
Airbus Defence and Space imagery captured on 19 September shows two of North Korea's new corvettes at the country's northeastern port of Najin in Rason. Believed to be the continuation of a programme first learned of in 2014, the hulls are approximately 77 m-long and share a similar layout, with an emphasis on modern, reduced observable design.

The primary difference is the presence of a 28 m-long helipad encompassing the aft section of the older corvette, which has been alongside at the port since as early as June 2013. The newer corvette, featuring an expanded weapon fit and present at the port since at least August 2016, eschews the helipad for additional superstructure elements and weapon fittings.

Two additional corvettes were present at various times at a port in the western city of Nampo. A helipad-equipped model was present between June 2012 and April 2014, while the newer, helipad-free design appeared in August 2014. The differing times at which the hulls were visible at Najin and Nampo suggests that there are currently two of each design.

The satellite imagery confirms an 8 November report by the NK News website, which showed photographs also taken in 2016 of the modern-style corvette at Najin featuring radar cross-section (RCS)-reducing characteristics.

According to the report, the reduced-RCS corvette spotted at Najin is equipped with a short-range surface-to-air missile system, torpedo launchers, rotary cannons, and two launchers for the Kumsong-3 anti-ship cruise missile system.

The Kumsong-3 is thought to be the North Korean designation for the Russian 3K24E Uran-E system and its 3M24E missile. The system is believed to have been exported to North Korea.

The Kumsong-3 is also referred to in the West as the KN-9, although there is some confusion regarding this designation, given that it has been used for both the Kumsong-3 and a 300 mm multiple rocket launch system.

Two sets of photos taken during different periods in 2016 show a heavily armed, 77-meter long vessel with radar cross-section (RCS) reducing features docked adjacent to a helicopter-capable but minimally armed support ship.

Equipped with two Kumsong-3 anti-ship cruise missile launchers, a short-range surface-to-air missile system, torpedo launchers and rotary canons, the reduced-RCS corvette also includes capacity for large caliber naval cannon

Im impressed what North Korea is capable of building despite the worldwide harshest sanctions.
Maybe they have some unofficial help from China, Russia, Iran..., just to keep balance against "the west"

surface vessels are projection of power and presence.
they have theyr justification, but lets face it, they are are vulnerable
especailly if you have enemies which are not 3rd world countries and can defend themselfes.
I would say put the majority of ressources/money/time... into submarines

As I said!
Their Anti Ship Missiles have far lesser range & and are fewer in number than Iran's Mowj Class
They have rotary cannons so again a less advanced & less powerful cannon that Iran's Owj Class
Iran's Jamaran, Damavand & Sahand are equipped with antiaircraft missiles that can hit targets ~25km & +50KM(Sahand) & theirs is under 8km max
Iran has a far more advance electronics, sensors & radar almost more advanced everything!
Their ship is 77meters long ours is 95 Meters with a much shorter Helo pad so it's far better equipped with a greater range.

Reduced RCS on ships is overrated!!!!!!!! Did reduce RCS help the UAE SWATH ship from getting hit? NO IT Didn't!!!!!!!!! It's just reduced RCS NOT Stealth!!!

Vevak, is Iran working on Vertical Launch Systems for its vessels?

To me it wouldn't make much sense if they weren't working on it!!!!!! only problem with that would be firing your missiles while on the move! Good for a cruiser armed with land attack cruise missiles and ships deployed in large fleets

If they build a vertically launched Cruise Missiles then you can store land attack, anti ship & anti aircraft missiles all neatly stacked in one area saving a lot of space! makes perfect sense to me but may not happen with the MOWJ Class!

Iran's been kinda secretive on the one that's coming out after the Sahand so we'll see!
Bavar 373 will be vertically launched... And making cruise Missiles vertically launched wouldn't be that complicated!

ALCON,

My first post here at this forum & y'all look like you're having plenty of fun so why not hop in?

My take on the comparison of NK's 77meter Corvette (both variants) and the Mowj-class Frigates:

-Point Defense: To date, the Mowj's defense against AshMs is definitely inferior to both variants of the NK corvette.
The single-barrel 40mm Fath (which CAN be automated but is clearly still configured for manned-used as well) can't compete with the rate of fire of NK's AK-630 based CIWS now standard on many of their new vessels. Iran did show a glimpse of a AK-630 being tested, so hopefully the Sahand will have better a better point-defense compared to her predecessors.

-SAM: Definitely a strong point but also a somewhat limited one at present, given the low number of rounds on the current Mowj-class vessels (Damavand-2 and Jamaran-4). We'll have to wait to see what the Sahand's SAM load-out ends up being. IMHO, she could end up sporting 8 SAMs depending on how they decide to use available deck space.

-Helipad: Actually, if that report is correct, the NK's corvette (helipad variant) has the larger helipad. The Mowj-class to date have a helipad measuring ~22 meters long vs 28 meters of the NK vessel. That said, the NK corvette helipad variant is a bit puzzling. Building a corvette with a helipad large enough for a light/medium type helos is fine and dandy but that's a nasty price to pay for limited armament (aka no AshMs apparently). Only IF those helos were ASW-equipped would that trade-off make sense.

-AshM: The article states that the NK corvette will likely sport two sets of launchers but I would bet they are likely two twin launchers, as this is the configuration seen on NK's latest missile boats. If that's the case, the non-helipad equipped variant of the NK corvette would be similarly equipped as the existing Mowj-class vessels.

--To-date, based on the design of the launchers, the Jamaran is fitted with *standard Noor/C-802 launchers, as opposed to the Damavand (which IS fitted with improved members of the Noor family). Assuming the Sahand is fitted with the improved members of the C-802/Noor family, she'll be better equipped than any NK-vessel to date.

-Sensor Suite: North Korea is clearly working on more advanced radar designs as seen in their KN-06 SAM system (can't remember their domestic designation for it at the moment). That said, there's little evidence NK has the same kind of radar/optic technology Iran is now fitting to her naval vessels.

Conclusion: The newly spotted non-helipad equipped NK corvette is definitely in the same class as the existing Mowj-vessels, though just a bit inferior in "kit". It has superior point-defense systems but is entirely dependent on land-based SAMs for BVR air defense. The helipad-equipped corvette is something of a mystery at this point. Unless NK gets their hands on proper ASW helicopters in the near future, with no AshMs equipped, it's going to be a sitting duck in any conflict scenario.

Cheers!

FYI: The ex-USN HSV-2 Swift was not a ship with RCS reduction: the ship is a wave-piercing, aluminum-hulled, commercial catamaran with military enhancements, such as a helicopter flight deck, vehicle deck, small boat and unmanned vehicle launch and recovery capability, and a communications suite.

Are you Eagle2009 from IMF?

ALCON,

Indeed, few if ANY reduced-RCS actually claim to be "stealthy" enough to defeat an incoming radar-guided AshM. With naval vessels, which have MASSIVE RCS to begin with, the purpose of reducing its RCS is to: A) Reduce your apparent size on enemy radars, so as to confuse them as to what kind of vessel they are tracking in the first place and B) to force them to come closer to their intended target to get a more proper/guaranteed radar lock before firing.

As such, if you enemy is targeting your vessel from over-the-horizon (or by air), the fact your vessel has lowered-RCS is rather pointless suddenly and you still need the traditional layers of air defense/counter-measures to defend yourself.

And for the record, since this keeps getting talked about. The HSV-2 Swift, to my knowledge, had absolutely no defensive systems to deal with an incoming AshM whatsoever. Thus the fact it got hit by a AshM fired by the Houthis is hardly a shock. The only "shock" is the how the poor thing managed to NOT sink. The Swift was not a true warship in the first place (aka she had no real armament). She was effectively a high-tech/speed transport vessel, aka a sitting duck!

AmirPatriot,

Indeed! Noticed the IMF just went and disappeared on me a year or more ago. Didn't know many of the IMF folks had set up shop over here until pretty recently. Turns out I had set up an account here many years ago and totally forgot about it.

That's fantastic! I'd been looking in other forums for you, but I guess you don't use the same username. It's great to have you here and I sincerely look forward to your posts, as I did on IMF. Catsoo said in a Farsi language forum that Izirbat had stopped paying for the site, which is really unfortunate.

JEskandari,

That does seem to be a factor and if so, should encourage Iran to continue their work with multi-hulled vessels. Also, if I was the folks running Incat (who built it), I'd be using that episode as a selling point of the company's workmanship!
