Safineh / Mowj 2016 -class (Wave 2016 -class) Trimaran destroyer

Iranian Defense Minister Brigadier General Hossein Dehqan visited the latest home-made equipment of Iran's new under-construction warship, “Shiraz”, Fars News Agency (FNA) reported 21 November 2020. Rear Admiral Khanzadi pointed to the preliminaries of constructing “Trimaran” Vessels and added, “Construction of this vessel, which weighs more than 3,000 tons and has good offensive capabilities, is on the agenda of Iranian Navy so that its conceptual and detailed designs have also been carried out. The plan for the construction operation of this vessel will begin in the coming years.”

Turning to the high capabilities and potentials of talented manpower in the Iranian Navy Force, he said, “Today, country’s Navy force has reached a level of capability that is able to meet its needs in the country relying upon its experienced youth and competent, professional manpower,” A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or “floats”) that are attached to the main hull with lateral beams. ccording to the correspondent of the Defense and Security Department of the Political Group of the Young Journalists Club, the 2009 Navy Day was very different from previous years, because the replica of the advanced Trimaran destroyer was unveiled as part of the Negin project and was scheduled to join the Navy "soon".

The knowledge of producing such a vessel is available only to a few countries and today the Islamic Republic of Iran has put its name in this category, but some features of this vessel that will be produced in the near future are used for the first time in our country's Armed Forces vessels. And therefore the deterrent power of the country will increase.

Trimmarans are multi-purpose vessels that, in addition to having common features with other vessels, have unique features such as high maneuverability, minimal hydrodynamic resistance, and in addition the ability to carry more special equipment. This type of float is made with a multi-hull design, which consists of a long, slender central hull and two side hulls, and the transverse deck connects the side hulls to the main hull, also known as three-hull hulls.

The design structure of the body of the "trimmers" causes the float to stabilize, and the main body of the structure neutralizes the tensile waves of the sea, the drag force (the force that keeps the body in motion in fluids) by neutralizing the tensile waves of the sea, and increases the buoyancy rapidly. Trimmers move easily between waves at high speeds due to their minimal hydrodynamic resistance (the amount of resistance to motion in a liquid).

Another feature of these vessels is the high level of hydrostatic equilibrium (the amount of equilibrium in the liquid fluid) which makes the destroyer not easily sink with resistance to pressures and currents. This feature has been considered by marine industry experts and this issue to Iran. It has led to its production.

One of the most important issues to be seen in the construction of the destroyer is the discussion of the defense capability of the vessels using defense systems that our armed forces used in this field, which resulted in the production of a lanyard point defense system, which is used in short range. With a range of about 4 km, it is able to neutralize any threat by playing 4 to 7 thousand rounds per minute.

In addition to this equipment, the designers of the Islamic Republic of Iran were able to acquire the knowledge of vertical launch of missiles from the ship a few years ago. This system is to be installed on new vessels, in which case Iran has a defense capability due to its defense missiles.

On the other hand, due to the construction of the Bavar 373 long-range system, it is possible that within the next 2 to 3 years, when the destroyer of the Negin project reaches the equipment installation stage, it will be possible to produce a sea-based model and join the new vessel to increase defense capability.

The ability to fire vertical missiles fired from a float causes the destroyers of the Islamic Republic of Iran, which to date can carry only 4 to 8 missiles from sea to sea, to increase the number to 24 to 96, which means increasing the offensive power of our armed forces. Great variety in sea-to-sea missiles.

But it is safe to say that the most prominent feature of Iran's new ship will be its radar, destroyers, because the Trimaran, due to their multi-mission and high operational expectations, should be able to track, prioritize and allocate appropriate weapons to various air, sea and air targets at any time. Have a subsurface.

The young naval specialists of the army have already proven their ability to produce radar by building a Samen system capable of simultaneously colliding with 5 naval targets and one air target, and then using a highly advanced radar-type fuzzy array radar capable of They produced simultaneous collisions with 12 targets at 360 degrees around the ship.

Another feature of Iran's new destroyer is propulsion systems. In the country, many efforts have been made in the field of production of heavy diesel engines and gas turbine jet engines, and although no specific information has been published so far, but based on foreign examples can be He realized that our native vessel could reach a top speed of 50 to 55 km / h and an operating range of 8,000 to 13,000 km / h at about 30 km/h. Iran's state-of-the-art vessel has other capabilities such as carrying two helicopters in the hangar designed for the first time in native vessels, significant reduction of noise or production noise, less space occupied and reduction of cost and maintenance time of the vessel, which makes the ratio Have the upper hand over competitors.

With the construction of such a vessel, it can be said that the navy, which is responsible for protecting the interests of the Islamic Republic of Iran in extraterrestrial waters, due to comprehensive military sanctions in recent decades, experts relied on internal power and in this direction the different needs of forces.

The use of hull design in the future naval ships of the Army of the Islamic Republic of Iran will cause a very high space in fuel resources and more supplies in the ship. According to Tabnak Semnan: Our country's experts in the field of building warships have so far made products in two categories and put them into operational service. In the category of hull length of 47 meters and carrying tonnage of 275 tons, the submarine of "Sina" category and along the length of hull of about 94 meters and tonnage of about 1400 tons, the protective ship "Jamaran" and its subsequent aircraft have been built. Soon 2 more vessels will be delivered. The Navy of the Islamic Republic of Iran.

But all of these vessels, and even subsequent designs under construction in the Navy, the large Persian Gulf combat training ship and the heavy destroyer of the Negin project, are conventional single-hull design vessels. In the world of boats, other designs have been used, boats with two hulls known as "catamaran" and three hulls called "trimaran".

There are several advantages to using this design compared to a single body or monohull design; Increased stability, no need for balance tank, wide deck surface, higher volume of water line, more safety due to accidents leading to body splitting, possibility of operating in shallow water, lower hydrodynamic resistance at higher speeds, radar cross section less than the side, Floating design with less length in one tonnage and volume similar to single hull float.

In a three-hull float, in the event of an unstable force from the sea, the two-hull floating forces easily neutralize it due to the distance to the center of gravity. A 63-meter Indonesian military Trimaran, which uses carbon fiber extensively, was also built in 2012. The Chinese are also in the process of carefully designing a 142-meter, 1450-ton Trimaran warship with a maximum deck width of 32.6 meters and a top speed of 55 to 65 kilometers per hour, equipped with HQ-16 medium-range vertical air defense missiles.

During the commemoration of the Navy in December 2009, in the exhibition of the achievements of this force, a three-body combat floating project called "Hormoz" project was unveiled. The commander of the navy introduced the vessel as the 2016 wave with a tonnage of 2,000 to 3,000 tons. From this point of view, the Iranian three-hull warship is almost in line with the American Independent ship and the Chinese model, so its length is probably estimated at about 120 to 130 meters and the width of the hull at about 30 meters. According to the commander of the navy, the design work of this ship has been completed and the construction work will start in 1399, as a result, more and more accurate information about this new Iranian ship will probably be published this year.

This design is a move to change the design style and context from conventional single-hull vessels to one of the most advanced designs among military ships, of which several more examples have not yet been made, and their history dates back to the last two decades or so. One of the features that can be seen in the 2016 or Hormoz project is the ability to maintain the helicopter in the hangar. Older ships built abroad, namely Khark and Bushehr support ships, have had helicopter storage hangars, but so far, only Iranian helicopter landing and flight decks have been installed and their own hangars have not been provided. Despite the hangar, the helicopter will be able to provide complete protection in all weather conditions and much better maintenance.

Another point is that Iranian trimmers use two hangars, so it will probably be possible to carry two helicopters, this is due to the greater width of the fuselage in the three-body design or trimmers. Of course, this width also means a wider deck, so large helicopters such as the SH-3D Siking and RH-53D Six Stallions can also land and take off on this deck.

In designing the lines and hulls of this ship, the principles of radar concealment design have been used a lot. Large integrated plates, inverted angles on the horizon, and the coordination of the angles of the various sections as much as possible are some of the points that reduce the floating radar reflection. And cross plates are designed.

Two anti-ship cruise missile launchers on this ship are also capable of rising before firing and retracting after firing, and are normally placed on the highest deck behind plates of the hull. This eliminates the radar reflection of these launchers on the surface search radars of enemy vessels. It should be noted that in Sahand ship, where the principles of radar concealment design are relatively observed compared to Jamaran ship, its detection range in radars has been reduced to one-sixth.

Another feature of the new Iranian destroyer plan is to equip it with four "Kamand" artillery point defense systems. Each grip of this system uses a 6-barrel cannon with a caliber of 30 mm and has a firing rate of 4,000 to 7,000 bullets. Due to this volume of fire, the bow has a very high ability to destroy air targets, especially anti-ship cruise missiles in its range.

The arrangement of these cannons on the Wave 2016 warship is such that each side of the ship is covered by two grips, but the grips on the other side will also be able to cover the targets within a short distance. 2 of these cannons are installed in the front of the ship and 2 in the end and before the helicopter deck. These two handles are installed at the highest height of the body.

The main cannon of the Iranian three-hull ship will most likely be the Fajr 27 76 mm cannon, which is an all-automatic weapon capable of destroying various surface and air targets. The firing rate of Fajr 27 is 120 bullets per minute and it can be targeted with radar and electro-optical systems. The effective range of this sea cannon is 12,000 and its final range is 17,000 meters.

This phased array radar, which was introduced in December 2016, is the second radar design of Nedaja self-sufficiency jihad using the power of internal experts. Before the Iranian Trimars, several other warships, including Damavand?2 and possibly Dena, are set to use this type of radar. The Eagle Eye Radar is a fixed antenna that uses four antennas, each with 1,000 elements, to cover 360 degrees. These four antennas are positioned at a 90-degree angle to each other and cover the entire perimeter of the float. Eagle eyes can detect more than 100 surface and air targets simultaneously.

The range of this radar, which operates in the S-band, is about 200 km, and each side of this radar has the ability to lock on 3 different targets, and in total, the vessel equipped with the eagle eye has the ability to engage 12 targets simultaneously in its surroundings. This radar uses advanced electronic anti-warfare (ECCM) capabilities using special techniques such as random transmitter pulse transmission, fast frequency shift and switching, jamming analysis (electronic warfare) for the transmitter system, time sensitivity control, changes Fast pulse repetition frequency and pulse compression are exploited.

Given that the Wave 2016 is likely to reach the stage of equipping and installing equipment in 1402 or later, it is possible that an improved version of the eagle's eye will be installed on it. The important point is that the arrangement of radars on the 2016 wave has two rows of antennas and 3 antennas in each row to cover 360 degrees, ie the Hormoz project float uses a total of 6 radar antennas. Unlike the current example of the eagle eye, where each antenna must cover 90 degrees, in the arrangement observed on the new Iranian three-hull ship, each antenna must cover 120 degrees. This in itself indicates the use of a different sample of the eagle's eye on the 2016 wave.

According to the proposed design, the Iranian Trimaran destroyer has been able to install 96 vertical rocket launch silos due to the much more space it has received due to its hull design. Similar to foreign types, these silos will be capable of storing a variety of missiles from short-range to long-range air defense and cruise missiles against ground targets. 6 sets of 16 vertical launch silos can be seen in the front or chest of the Wave 2016.

The use of vertical-launched air defense missiles is to be used for the first time in Damavand and Dena ships, which will be delivered to the navy in 1399, but these missiles are of the short-range type.

According to the new design, it is possible to create enough space in the Wave 2016 to carry long-range long-range missiles with a length of about 7.5 meters, such as models suitable for sea-based use of the Fisherman-24, which currently cover a range of 200 kilometers.

These missiles extend the air defense capability of a warship beyond the tactical level and enter the strategic area. The long range, high altitude, and ability to engage multiple targets simultaneously, which is likely to reach 18 targets in 2016, assuming the basic capabilities of the Eagle Eye System, enable the warship to have excellent air defense capabilities and the ability to change strategy in battle.

A vertical launch silo of a long-range foreign air defense missile is being placed on the ship. The same launch silos, like foreign models, will be equipped with medium-range missiles and up to four smaller-diameter missiles to cover short-range and less important targets.

Another point is the possibility of equipping the 2016 wave with anti-ground cruise missiles by means of vertical launch silos. These missiles are made from a range of 700 to 2000 km in Iran, and the development of a seabed and can be fired from a vertical silo is also available to our missile specialists. With these missiles, the Wave 2016 acquires extraordinary offensive capabilities and the ability to impose political will, which is one of the main uses of a strategic navy. Combining the 2,000-kilometer range of the missile with the multi-thousand-kilometer range of the 2016 Wave, and of course the large number of portable missiles, can make it a high-impact nut in military conflicts.

Moving towards the use of the new hull design in the new warship of Hormoz project or Moj-2016 has caused a very high space for carrying various missile weapons, helicopters, strong defense and of course more fuel and supplies in the hull, by preventing excessive increase of the vessel length. Undoubtedly, the construction and operation of combat ships with advanced design and with this level of capabilities, in addition to increasing the spirit of self-confidence among the community and especially professionals, also plays an important role in increasing the naval capabilities to increase the strategic weight of the force.

In November 2019 Iran showed off a new Trimaran warship design under the "Safineh" (Arabic for “boat”) project. It is reported that the ship has a displacement of 3,000 tons and a speed of 40+ knots. It is equipped with a 96-unit vertical launch system, 4 Kamand close defense systems, and a 57/76 mm main gun. , Dual hangars, multi-area array active phased array radar, anti-ship cruise missiles. Although the overall level is not high, Iran's defense industry has always been known for its ability to do things in the third world countries. After the ridiculous F-313 "Conqueror" stealth fighter was made public a few years ago, the Iranian navy reluctantly proposed the Safineh-class guided missile destroyer concept. And this legendary battleship has finally unveiled her mystery recently.

Compared to the various types of ships in active service, this model, which obviously uses a trimaran design, is full of sci-fi style. It is reported that the displacement of this class of ship is about 3,000 tons. It can be seen from the figure that in addition to the main gun and the near-defense system, the ship's bow is also designed with a 96-unit vertical launch device.

The huge helicopter deck of the Safineh-class guided missile destroyer and the 4 sets of water jet propulsion devices on the bow of the ship are the first to enter everyone's field of view. The ship's speed can reach 40 knots or more under the promotion of other doors. . In addition to the double hangar, the design of the integrated mast of this class of ship is also quite evident. It is reported that this ship model will be equipped with Iran ’s self-developed active phased array radar.

Although the small-caliber naval gun system above the hangar looks like a "Millennium" gun, it is actually a self-developed "Kamman" near-defense gun. Obviously, this ship's ultimate defense task is mainly undertaken by four "Kaman" close-mounted guns installed on the bow and hangar of the ship. At the rear of the main mast, the ship also built two 4-unit anti-ship missile launchers.

Before the model was officially disclosed, the Iranian Navy officially announced the concept map of the Safineh-class guided missile destroyer on 08 December 2018. Visiting the Navy exhibition, Habibollah Sayyari, the deputy army chief for coordination affairs, unveiled the scheme for the new homegrown vessel, dubbed the “Safineh (ship) project”. The Iranian trimaran will have low hydrodynamic resistance in high velocities, have appropriate hydrostatic balance, and enjoy a large deck, twice as big as a single-hull vessel of the same tonnage. With a speed of above 40 knots, the military vessel could be employed in guerrilla warfare on the coast and for rapid reaction operations.

It is worth mentioning that it was later pointed out that the concept of the so-called Iranian-made new-generation destroyer is actually directly using the photos of the famous US Navy "Independent" class littoral combat ship. The Iranian Navy's Safineh-class guided missile destroyer basically copied the design of their old counterpart, the US Navy. It is difficult to imagine that with the current level of Iranian military industry, this concept can be transformed into reality. Not surprisingly, the final outcome of this rather sci-fi warship can only be another ridiculous navy version of the "conqueror".
