The new details of Iranian Trimaran Frigate, “Safineh”

[Mithridates]

the problem is that a blast rip apart aluminium sheets like papers , if you want your ship be as strong as an airliner you'll bult it with Aluminium , if you want it to be a arship and have any chance of survival in battle field (getting hit by missiles, torpedoes or mines ) you'll build it by steel or Titanium .
look at this ship , you think how it would have faired if it was built by alluminium

and it only hit by a single exocet , you may not build armored ship anymore but it dont mean you build it with paper

bro Norwegian skjold class corvette is built from glass fibers...so i assume aluminum alloy would be suitable material.

come on that's only a 247 ton ship not a 3000+ ton one its in class of kaman patrol boat

and as far as i'm aware glass fibre/carbon composite composite that is used in its body is a lot stronger than Aluminium and by the way its not a catamaran its a hybrid between hovercraft and catamaran.
India wanted to build Kamorta class corvette from that material but they had to change it to a combination of Steel and glass fibre/carbon composite
the biggest ship built entirely out of glass fibre/carbon composite is 640 ton Swedish Visby-class Corvette

if Sweden can build visby with glass and carbon fibers then we can do it too. but it's too soon for conclusion we should wait and see whats gonna happen.

the problem is Visby is 1/5th of the size we aim for and its probably slower , but yes we must wait and see .
by the way my concern for the ship is not what alloy they use in the body , I wonder what engine they want to use , hope its not Bonyan .

Modern warships have layered defenses in order to stop the missiles from reaching critical areas, but once those layered defenses fail the ship is vulnerable to damage.

Go look at the damage of a US cruiser collision with a massive container ship. Or the Iranian Mowj that hit jagged rocks on the coast.

The stronger you make the armour the less maneuverability, speed, etc you have. It’s a trade off.

Shipbuilding is a parent industry. Its products are the extract of all of the technological achievements and national talents of a nation. A host of exclusive and expensive cutting-edge technologies are used to build a destroyer — some of them may be used only once and only on one product. An expansive range of all of the military equipments that is used on the ground is reconfigured for adaptability on sea and is used on a military vessel.


Machine guns with high rates of fire, artillery guns, missile systems, all types of anti-ship and mid-range ballistic and cruise missiles, drones, torpedoes, the most advanced technologies for radars, electronics and communications, hulls and propellers, aerodynamics and hydrodynamics, pyrotechnics, technologies for welding, cutting, formwork, and sheet metal work, advanced and meticulous engineering calculations, technology, process, and services management, and a high volume of materials, hardware, and human resources at one very large facility or at separate ones come together and offer their final achievements to build the final product that is a military vessel or a submarine. An Iranian battlecruiser is the true representative of Iran’s entire defense industry.

Therefore, if a country manages to operate a meaningful naval industry, it will have exploited many of its capacities in an effective manner. Such activity will not just lead to a financial turnover, employment, and the development of novel technologies, but will also help drag super-advanced small, medium, and super-heavy shipbuilding-related and other related industries out of inactivity. And all of that will be in addition to the boosting of the country’s defense power.

At present, Iran’s Navy does not fare favorably in technological terms and in terms of the quantity of large vessels such as frigates and corvettes that it deploys. The coasts of the Persian Gulf and the Sea of Oman, stretching past 1,400 kilometers, are protected with a fleet of boats with missile-launchers, frigates, and small submarines in addition to on-shore security measures. In the event of a full-scale war, those forces would not be able to break a maritime embargo deep into the Sea of Oman or to protect shipping and maritime borders for a sustained period. The defensive and offensive capabilities of the Mowj-class vessels, which are the spearheads of the Iranian Navy, do not match the threats and necessities of the near future, or perhaps even those of the present. None of them would survive in an off-shore battle without aerial or on-shore covering fire. That is not because of weaknesses in them, or in the Air Force, or because there is no suitable technology to defend them; rather, it is because of the weaknesses in their old designs, which go back to the 1970s. Because of its lack of experience in shipbuilding after the 1979 revolution, Iran had to use the same Vesper-class warships that had been purchased from England by the Pahlavi regime as the basis for the acquisition of knowledge in the field of battleship manufacturing. That happened because the experience, the necessary training, and the workforce were available and because the ships were interoperable with the other equipment that the Navy was in possession of from older times. Although new and updated equipment have been used on the Vesper (Mowj)-class vessels, the design of the vessels themselves does not correspond with the necessities that arise from present conditions and threats. The Islamic Republic of Iran Navy has realized that and has taken very important steps toward revolutionizing the Navy with domestic knowhow. Iran’s defense achievements are many and are varied.

Iran’s air defenses now display real advances that have been proven in real combat. The Talash (Endeavor), Bavar (Belief), and Oqab (Eagle) missile systems can all be used on the sea as well. The Cheshm-e Oqab (Eagle’s Eye) phased array radar system has been exclusively designed for application on the sea. So are the Bavar (Belief) vertically-launched missile that comes with silos designed to take less space on board a vessel, the Soomar, Hoveizeh, Ya Ali, and Mobin cruise missiles, and the new generation of anti-ship supersonic cruise missiles currently being developed. None of the Navy’s current ships are capable of exploiting the above-mentioned equipment and technologies — which are fully accessible — in terms of adequate space, weight, the propeller’s strength, and suitable accommodation capabilities.

The necessity of designing new battleships of heavy classes

Special plans are underway to that end. The Shiraz surveillance battleship, the Loqman training battleship, the Dena battleships, and the very promising Safineh trimaran project. It is worth mentioning that the first Mowj-class battleship took 12 years to design and build. But once that period was over, according to Admiral Khanzadi, the commander of the force, Iran could build a battleship in the Mowj class such as Dena within 18 to 24 months. The Dena battleship series is equipped with vertical launch systems and the latest generation of Iranian-built, advanced sea-based radars. The massive, 6,500-ton Loqman battleship (of the Persian Gulf class) is currently under construction after seven years of designing and engineering work and will be launched in four years.

The Safineh trimaran can itself be mounted with a large spectrum of other achievements, including from aerial industries (new helicopters such as Shahed, Homa, and Saba). Due to its use of 96 vertical and eight horizontal launchers, Safineh can have all defensive and offensive capabilities at the same time. Adapted versions of sea-based cruise missiles, such as Soomar, Hoveizeh, Ya Ali, and Mobin, which, in their new sea-based formats, can be used against ground targets within 450 to 1,500 kilometers of range, are among the notable options to be used on those launchers. The Sayyad-3, Sayyad-4, and Bavar 373 missiles can be used in defensive operations in support of the battleships and to ward off aerial threats in ranges of up to over 150 kilometers. The jet-engine Sejjil and the VTOL Pelican drones are the latest achievements of Iran’s aerospace industry. In terms of electronics, avionics, and radar, the battleship will have the necessary design to use the most advanced detection and target-acquisition phased array Cheshm-e Oqab (Eagle’s Eye) radar.

With the necessary technologies that will be used to design and build new generations of Iranian battleships on a rare level and perhaps even beyond the standards of the day, Iran will not only provide the necessary advancement for the future of its Navy but will also move to provide growth and permanent employment in other related industries. As such, it will have also remarkably prepared its military for new threats, for presence in high seas, and for the due protection of Iran’s maritime borders. Security comes before economy, and a powerful navy will protect a powerful economy.

I don't see anything in that design suggesting it cannot carry 96 VLS when it clearly is showing to carry 96 VLS i.e it is designed to carry 96 VLS whilst the US LCS is not. This does not mean the US cannot build a ship to carry that many VLS. If they want to, they can. So your reasoning is not sufficient. Saying "Hull simply does not allow for so many VLS" makes no sense given you can see the final design is carrying that many. So what is your claim based on exactly?

I am still waiting for you to explain to me using actual engineering reasonings why that design above is not feasible. So far you have only made claims.

I feel bad for you as you often have to deal with some of the more intellectually immature and politically biased Pakistani members of this forum.
We mostly have a combination of laughable arm chair experts and trolls when it comes to Iran.

 

[TheImmortal]

Another reason why Iran’s version may have 96 where as other country’s do not. Is that the US is a military industrial complex, meaning the designer builds to make a profit first and foremost while meeting requirements of contract. They have no incentive to go above and beyond.

96 VLS ship = less ships needed = less profit potential.

Trimaran vs Normal Ships
https://dmsonline.us/why-you-want-a-trimaran/
Advantages
The trimaran offers several capabilities to bridge the gap between monohulls and catamarans:

• Excellent for high speed
• Moderate weight carrying capacity
• Good seakeeping capability
• Larger available deck area
• Moderate space below the main deck
• Heavier loads can be carried on the cross deck
• Less structural weight required for the cross deck
• Deadweight coefficients closer to monohulls

The long length of the center hull also offers great advantages for seakeeping. This length greatly reduces pitch motions in a wave, and the narrow center hull reduces chances of slamming. To improve things even more, the side amas reduce roll motions. They add stiffness to prevent large roll motions. But they also act to reduce roll accelerations. All together, trimarans make for gentle seakeeping.

The trimaran offers major advantages for damage survival. The side amas provide excellent protection to the center hull, which military designers find especially useful. But the cross deck also helps with damage survival by containing massive reserve buoyancy. Imagine a damage situation where the ship sinks down to its cross deck. On a monohull, that would be game over. But on a trimaran, the cross deck suddenly becomes a barge, easily supporting the entire ship weight.

In catamarans, you lose stability once a single ama completely leaves the water. Push a catamaran past that point, and stability is a losing battle. A fact that scares many vessel operators. Trimarans do not have this problem. They get stability mainly from submerging the amas. The center hull always stays in the water, and the leeward ama continues to submerge. This creates a predictable increase in righting moment. In normal cases, trimarans never experience the sudden loss of stability.

Disadvantages
The biggest disadvantage for trimarans is lack of experience. There are few trimarans in military applications, and even less in commercial use. That lack of exposure instills wariness in many operators.

Trimarans do have a few genuine detractors. Due to their complexity, they require some extra design effort. The cross deck introduces a few extra ways to twist and bend the ship, and the engineers must check each of these extra scenarios.
Cost definitely factors into trimaran construction. The cross deck and extra hulls do add extra steel to the design. You have to pay for that extra steel as part of the build cost. But don’t assume this drastically increases the total build cost. Adding extra structure is far less expensive than adding extra machinery and power.Consider the alternative to a trimaran: an equivalent monohull. For the monohull, we strip off the side amas and widen the center hull to maintain ship stability. But bad news. A wider hull requires a larger engine, and associated support machinery.
Adding larger machinery costs twice as much as adding extra structure.
The hull shape does not drive the price tag, and trimarans are not limited to high speed.Trimarans are just a hull configuration. How you use the hull is up to you.

Conclusion
Don’t let the previous trimarans limit your imagination. The trimaran hullform bridges the gap between monohulls and catamarans. It offers some advantages of both deadweight capability and larger deck area. Primarily, trimarans deliver ship stability in a very power efficient package. What uses can you imagine with that flexibility?

I think the main question now is, what size are those VLSs? If they are large enough for anti-ship missile systems, then this is one deadly ship with tremendous fire power potential!!

maybe but you must consider if they went with Iran design it must have been impossible for them to meet the criteria asked for them .
iran design have significantly larger front while in USA design the back of the ship is aignificantly larger., Iran probably wanted an attack craft or someting to protect the rest of the fleet, usa wanted the Independent class be able to carry two SH-60 or MH-60 Seahawk helicopters and a ramp at the back to operate a boat and the cargo volume and payload to deliver a small assault force with fighting vehicles. also you consider usa Navy changed its requirement for LCS ships and wanted one with more offenive capabilities ,so i t won't be strange for me future USA design will be more like Iranian design

wonder why people assume Antiship missiles are bigger than Airdefence missile
a RIM-66 is 4.7m long a wingspan of 1.07m and diameter of 34cm
a RIM-67 is 8m long a wingspan of 1.57m and diameter of 34cm
a RGM-84 or Harpoon is 4.6m long had a diameter of 34cm and a wingspan of 91cm

I wonder why people love to make assumptions.
First of all, who said I was talking about RIM series? Given the vast number of VLS system, they could be of small size for relatively short ranged surface to air missiles.

you said Antiship chambers are large and Anti Aircrafts are smaller
