I will admit that my knowledge in regards to ships and their propulsion is very low. So keep that in mind. However, as an engineer with fundamental knowledge regarding combustion engines, gears and shafts on the one hand and gas turbines and generators on the other, I have to say that to me it is not so clear why the aforementioned is more of a low risk. 8 engines will need an intricate gear and shaft integration. So the overall system is IMO more complex than gas turbine + generator + electric motor.
Also I don't think we need to compare so much with other countries. Many seagoing nations had 50+ years experience with combustion engines before introducing gas turbines. Obviously their legacy will have made the transition difficult. Iran on the other hand has very recently mastered both combustion engines and gas turbines.
In conclusion, my dream scenario would be for Iran to develop extremely robust gas turbines because that would be easily scalable and the overall solution is IMO simpler and more elegant.

I'm not talking about the complexity of construction, certainly my hypothesis has more gearboxes, more motors, more propeller shafts, more etc. For low risk I indicate why this propulsive solution (CODAD) has already been implemented in Iran and is operational at least on the Sahand-74, therefore a solution that could be repeated and expanded in number having gained direct knowledge of the components and their use.
In repeating myself, a CODAG configuration would be a better option, then also the different configurations to use electric motors; but with these we should still be in the field of research and design, yes, perhaps something has developed in the propulsion sector of diesel-electric submarines, but to push a heavy destroyer you need something much more powerful.
However mine, indeed ours, are only hypotheses; instead in a recent interview it was stated:
"In the defense ministry we are working on the construction of a 6,000-ton destroyer in the long-run," he said, "Executive preparations of the project will commence this year."
Therefore I think that the Iranian Navy has already planned the type of engines and the type of propulsion it will have to install on this destroyer.

Iran doesnt just build them it also redesigns and improves them considerably as we saw with the MGT-70.I suspect this was one of the reasons why siemens did partially honor its deal to supply iran with F Class turbine technology to enable the local manufacturing,and redesign too no doubt,of F Class turbines in iran.
https://financialtribune.com/articl...na-unveils-improved-best-in-class-gas-turbine
"Majid Bahmani, managing director of MAPNA Turbine Engineering and Manufacturing Company, a subsidiary of the group, told the same conference that the 2.2% increase in efficiency of third-generation MGT-70 turbine is a significant technological leap.
To put it into context, Siemens, one of the world's biggest turbine manufacturers, introduced an E-Class turbine in the early 1990s with 37% efficiency, but it took the company over two decades to enhance the number by 3%," he said."

Do not use facts and logic with @VEVAK, it escapes him.
This man is saying use foreign engines on a destroyerand then follows up with blind confidence that Russia and China would supply Eastern engines.
It’s as if for the last 30 years Iran hasn’t been screwed over in engine technology for aircrafts,tanks, etc. but suddenly Russia and China will line up to provide Iran’s destroyer fleet access to engine tech. I’m still waiting for the RD-33 Iran ordered in 2003 for Shafaq to show up. Maybe Vevak can reach out to Russia customer service and see what the hold up is?
Like I said Iranian engineers are keenly aware of the challenges they face. The French engine fiasco showed that even for a frigate the West will not allow Iran easy access. So imagine what would happen if Iran tries to build Destroyers and Cruisers? You can be damn sure that US and EU would sanction any company helping Iran to build these massive ships. So if Iran doesn’t have control over the key parts of a ships supply chain, THEN DONT BUILD IT!
Yea cause Iran has never been able to build and provide propulsion for a ship heavier than the Sahand!
Honestly how hard is it for you to think a little?
And the idea that you are somehow privy to every purchase and transfer of every part and component to and from Iran is without a doubt nothing more than your own personal delusion.
FYI 50 RD-33's would be barely enough to power and maintain 20 MiG-29's and if they were ever transferred to Iran more likely than not that would be the ONLY thing they would be used for because Iran's Airforce would have to be out of it's mind to chose 40 potential Iranian Shafaq's over 20 MiG-29's!
And lets be clear, you DO NOT know if they have or have not been transferred.
The rest, meaning info like putting RD-33's on Iranian designed fighters was nothing more than propaganda, guesses & assumptions of military annalists and hopes and dreams of regular Iranian military enthusiasts.
FYI a 3000-4000 ton warship is far from massive!
I suggest you get out that little bubble you've been living in

I hope we can to see Iran complete its bigger more advanced surface vessels so that future joint training exercises will portray Iran's NAVY is much more 'modern' light so to say.

However, despite the fact that the NAGHDI 82 in October will celebrate 58 years from the date of construction, this old lady of the sea is still in excellent condition, therefore an applause goes to the engineers, technicians and workers of the Bandar Abbas shipyard who, in addition to maintaining it operationally and aesthetically in these excellent conditions, he continues to update it with new weapon systems that have allowed him to expand the type of mission he can go on.

Twin hull stealth catamarans seem to be promising in future anti-ship and anti-submarine warfare in my opinion
en.wikipedia.org
This one uses supercavitation in both of its hulls
Still it uses underwater bladed propeller which can be noisy and can be detected by other submarines. Although it can escape from ship- airborne radars or infrared detectors if it is shielded well.
I think the propulsion can be made by bladeless propeller like jetoptera.
The propellers can be under the mainbody - passenger section above the sea surface. Since it is bladeless it wont contribute to radar cross section and it will be under the main body of the ship concealed from outside only visible from front and from back and there wont be any blades reflecting radar back.
This way it can work on both against submarines(no noise under sea) and ships(radar-ir stealth) in my opinion

Admiral Salvation: Foreign countries sabotaged the construction of the Jamaran destroyer
According to the defense group of Tasnim news agency , quoting the public relations of the Ministry of Defense, Admiral Amir Rastegari, head of the Ministry of Defense Marine Industries Organization, said: "In 1997, an exhibition was set up in the strategic naval factories of the Islamic Republic of Iran. At the end of the visit, he said: Go and build a destroyer. The soldier indicates the expectation of the commander, so we started the command with all the difficulties. At that time, our equipment was all Western, and at that time we were conducting and repairing, but all the equipment was imported.
Rastegari said: "The Supreme Leader also determined the characteristics of the proposed destroyer and asked us to build a destroyer capable of carrying helicopters and launching missiles, and the lack of a missile launch system in the destroyers of that time was a weakness for us." Open-air destroyers require helicopters and rocket launchers, and building the destroyer alone was a far cry from us, but they wanted helicopters capable of carrying helicopters and launching missiles.
He added: "The destroyer was built on February 20, 2010 and they also attended the ceremony of joining the Supreme Leader. We all remember that year. The Supreme Leader of the Revolution said in his speech that many people believed that the destroyer could not be built, but it was done and In your opinion, this destroyer is not a big job, and in his opinion, the basis of the work is the appreciation of human resources for their abilities and recognition of their talents.
The head of the Maritime Industries Organization of the Ministry of Defense emphasized: we must bring the talent and strength that God has given us to the field of action and we must not be afraid of the greatness of the work, the spirit of self-confidence and will; It has brought the country to the point where we can build a destroyer. The destroyer of the Islamic Republic of Iran was a turning point in the history of Iran's military navigation, and this destroyer is not only important for the navy, but also had great achievements for the country.
"Countries do not change platforms in the construction of destroyers, and there is no need to change platforms, and systems and systems change." We provide radars with more power and higher range, and the accuracy of submarines in targeting is increased, and we upgrade fire control, search, optical, sonar and forest systems, and after Jamaran destroyer, we succeeded in building Damavand destroyer. Sahand was also built in naval factories and in the near future we will have the Dena destroyer.
He added: "The Jamaran destroyer is completely Iranian and we have not received any help from any foreign element. All stages of design and production were done by local experts and this brought the Navy to the ability and construction of the destroyer." We need a design office for structural construction, propulsion and propulsion, radar, sonar, optics, missiles, artillery, and so on; It was also an achievement for the organizations of the Ministry of Defense that all the equipment such as radars and systems such as electronic warfare and sonar were made by the industrial organizations of the Ministry of Defense and also the civilian industries of the country were used in this matter.
The head of the Maritime Industries Organization of the Ministry of Defense stated: "Everywhere in the world, he works as a global consortium to build a destroyer and makes each part a country." But Iran makes all the parts with domestic potentials and we first bought the thrust system from abroad, but we faced the mischief of the manufacturer and they sent the engine to us, but the parts were not perfect. They did not send us parts like gearbox, cooling system and control. The engine could not be used and they were looking to sabotage it. A knowledge-based company designed and produced a 10,000-horsepower gearbox for the first time. About 60 industrial and knowledge-based companies helped us build the destroyer, and seawater pumps, switchboards, switchboards, and internal systems were built by these companies. I must also mention General Salehi and Amir Sayari, who had good support and follow-up.
Rastegari emphasized: One of the missions of the Navy of the Army of the Islamic Republic of Iran is to maintain the transportation lines of the country's commercial and oil fleet and Iran has sea connections with 5 world oceans and exports and imports goods through this in 2007 with the ominous phenomenon of piracy. In Bab al-Mandeb, we were attacked at the entrance to the Red Sea, and the navy of the Islamic Republic Army was ordered to escort the vessels.
In the end, the head of the Maritime Industries Organization of the Ministry of Defense said: The navy of the Islamic Republic Army has also served the fleets of other countries. A request was sent to the Iranian Ministry of Foreign Affairs through the Chinese Embassy, and finally, the Navy of the Army of the Islamic Republic of Iran was tasked with rescuing the vessel.

The 100,000 Ton US Navy Ship That Iran Is Copying - Naval News
The US Navy's gigantic Expeditionary Sea Base (ESB) ships are among the largest naval vessels afloat. They are part of America's unrivalled global reach, but they are no longer unique. Iran is testing a similar Forward Base Ship which is comparable in size.
