1500-ton Foreign Trade Frigate

On the whole, the new 1,500-ton foreign trade version of the frigate is similar to the Type 056 light frigate that has joined the Chinese Navy. Over the years China has done a pretty brisk trade in low end frigates for empoverished Navies such as Bangladesh or Nigeria, for which sophisticated European designs are too much of a good thing. With the seeming completion of production of the Jingdao Type-056 Frigates in 2018, a new export design may be anticipated. But in terms of weapon configuration, the new 1500-ton frigate is stronger than the 056 frigate.

At the Abu Dhabi-2013 Defense Exhibition, China displayed a variety of surface ships including helicopter carriers, export frigates and large patrol boats. It is reported that the foreign trade stealth frigate model first appeared on the Chinese manufacturer's booth at the Langkawi Defense Exhibition in Malaysia in late March 2013.

It is worth noting that the export-oriented 1,500-ton frigate was the first public exhibition in China. Its low visibility shape attracted the attention of all parties. It shows that China's ship stealth design has taken a new level. The new 1,500-ton frigate is closed to the hull, equipped with an overall mast and missile weapons to achieve full vertical launch. The overall stealth design and handling has reached a high level. It can be said that the future surface of the Chinese navy can be seen from this ship.

The ship is 97 meters long overall and has a speed of 30 knots. It adopts a deep V-shaped design. From the model point of view, the 1500 frigate is about 89 meters in length at the waterline, 10.1 meters wide and has a maximum speed of about 30 knots. It adopts a long bridge type ship type, deep V line type, and the long bridge ship type is a low side flat deck and a high flat flat deck. Compared with the former type, its ship has a large volume and can increase the larger internal space, which helps to accommodate more internal equipment. The electronic equipment and weapons of modern ships are increasing, so the ship increases the internal space. To accommodate these devices, compared with the latter, the upper center of the long bridge ship has a lower center of gravity, and the smaller displacement can ensure the initial stability of the ship, and can control the volume and displacement of the ship, thereby reducing the cost and construction cost of the ship. Therefore, it is more suitable for medium and light ships. Therefore, the long bridge type ship type was once the main ship type of Chinese and foreign frigates. The Chinese 053H and 053HZ model frigates, foreign countries such as the British 21 type frigate, and the country's MEKO are all this type of ship.

Of course, the long bridge type ship also has its own shortcomings, that is, the ship's bow and the ship's freeboard are low and easy to go up, so the ocean performance is poor. In addition, due to the limited space of the hull and raft, it affects the layout of the ship's weapon. Especially the vertical launch system, these two places are the main place for ship-borne weapons. Therefore, some offshore patrol ships and frigates in the new century, such as the Dutch SIGMA frigates and the French wind-class frigates, have adopted the Changchunlou ship type. Increase the hull space to facilitate the placement of the vertical launch system. According to some information previously released by China Shipbuilding Corporation, some new light frigates and patrol ships in China have also adopted the ship type of Changchun Building. For example, the patrol ship exported to Nigeria, the 1500 type frigate still adopts the long bridge type, which may be more Considering the cost and cost of control.

The main weapon of the 1500 frigate is a 76mm gun of the ship. It is already the main gun of China's medium-light ship. The rear of the ship is a 24-unit vertical launch system. The near-proof system is 2 Chinese 6-tube 30mm. Near the anti-missile naval gun, there is a large caliber machine gun on both sides of the chimney, showing that the ship can also be used to perform patrol missions. The ship has a helicopter landing deck and a hangar, and can take off and land a medium-light helicopter, such as a Chinese Z-9EC anti-submarine helicopter.

On the whole, the 1,500-ton frigate has a high level of stealth technology, which is not only higher than the Chinese type of warships such as the 054A frigate. Compared with some advanced surface ships, it is not inferior. From the model point of view, the hull and The superstructure consists of a smooth plane and slopes inward, eliminating two sides and three facets of the open air, closing the first floor deck and the tail deck. The surface of the hull forms a smooth whole, removing the railing of the original weather deck, and mooring equipment and winches. It is placed under the main deck under the weather deck, surrounded by bulwarks, with working holes on the bulwarks, which are opened when needed and closed at unnecessary times, which can effectively improve the stealth ability of the ship.

The biggest feature of the ship is the use of a monolithic mast for the first time in China's surface ships. From the appearance point of view, it is roughly equivalent to the fully enclosed mast/detector system (AEM/S) developed by the US Navy. The mast consists of two multi-faceted cones. The body is composed of a frequency selective material. The material only allows electromagnetic waves in its frequency range to pass. The advantage of the integral mast is that the stealth performance is good. According to the curvature principle of the earth, the mast is the most popular in the radar line of sight. The position of the ship, so improving the stealth ability of the mast is very important to improve the stealth technology level of the ship. In addition, the overall mast is mostly made of composite material, which is light in weight and helps to reduce the weight and tonnage of the ship. According to relevant information, the mast The weight of the top is increased by 1 kilogram, the keel part will increase by several hundred kilograms to ensure the stability of the ship, and the electromagnetic compatibility of the ship is improved. Because the antenna works in a closed space, the equipment is eroded by high temperature and high salt environment at sea. Lowering helps to increase the life of the equipment, in addition, the other party is not easy to get from the ship Line to determine the device is equipped ships, vessels and thus presumably tactical and technical indicators, it is no exaggeration to say that the whole mast is equipped with a large surface ships breakthrough in Chinese technology.

Another interesting aspect of the 1500 frigate is that it cancels the tilting anti-ship missile launcher. Modern ships generally have tilted anti-ship missile launchers between the bridge and the chimney. One explanation is that the 1500 frigate canceled the counter. The ship missile, its anti-ship capability is provided by the TL-10 anti-ship missile mounted by the straight-9EC, but considering the requirements of the scheduled market navy, the author thinks that this possibility is not big, the other one may be its anti-ship missile and Like the 052D, it integrates a vertical launch system. Thus all the weapons of the ship are launched by the group of 24-unit vertical launch systems of the ship.

Many people find it strange that a light ship of the 1,500-ton class can accommodate so many missiles. In fact, Chinese tactical missiles have made great progress in miniaturization. They can already support such equipment. For example, the Chinese C-705 The anti-ship missile has a launch weight of only 320 kilograms, and the thrust vector structure can be controlled to about 350 kilograms. The small missile speedboat can be equipped with eight such missiles, but its range is 150 kilometers, close to medium range. The level of anti-ship missiles, with a warhead weight of 110 kilograms, can attack medium-sized surface ships and is ideal for medium-light boats.

Another compact ship-borne missile is the DK-10 ground/ship-to-air missile. The missile was developed on the basis of the Chinese SD-10 active radar-guided air-to-air missile. The latter's active radar guidance system was retained. The larger solid rocket engine was replaced with side flaps for insertion into a compact vertical missile launcher. The DK-10 has an airborne range of more than 40 kilometers. This distance can already reach the water antenna and improve the ship's pair. Air defense capability, its length is about 4 meters, and its weight is about 300 kilograms. Another advantage of the DK-10 missile is that it uses the last active radar guidance system, which does not require the ship to illuminate the radar, thus simplifying the ship's The radar equipment reduces the center of gravity of the ship and further improves the electromagnetic compatibility of the ship. This assumes that the 24 units of the 1,500-ton frigate are equipped with eight C-705 anti-ship missiles and 16 DK-10 anti-ship missiles, so its weight should be around 7 tons, which is acceptable for the ship. However, the problem with the DK-10 is that the missile may not be fully mature. In addition, it may be more difficult to implement a unit to launch four missiles. Therefore, for China, it may be necessary to develop a new missile to improve the capacity of 1,500 tons of guards.

To solve the complete missile problem, the rest is the ship's detection system. From the model point of view, the 1,500-ton frigate has almost no detection system except the integral mast. It can be considered that all the detection systems are integrated into the integrated mast. At present, there are two types of integral mast detectors, one is ordinary radar and electronic equipment, which is divided into multiple layers, which are equipped with radar and electronic equipment respectively. The whole mast like the Netherlands is such a structure, it is from top to bottom. The first layer is the navigation radar and the electronic reconnaissance system, the second layer is the three-coordinate warning radar, the third layer is the multi-function radar and communication equipment, and the fourth layer is the equipment cabin, which mainly includes communication and data links. There is also a radar and mast integrated system, that is, the radar and communication system are embedded in the mast by a multi-face array to form an integrated radio frequency system, such as the electronic system of the American DDG-1000. The former one is relatively simple and the cost is relatively low, but The disadvantage is that the maintenance is more complicated, so many electronic devices are arranged in a relatively narrow space, and the solution to the problem of cooling and electromagnetic compatibility It is more difficult. The latter can simplify the electronic equipment of the ship, realize the integration of electronic equipment and superstructure, and improve the stealth ability of the ship. However, the technical difficulty is high and the cost is high. According to the traditional market of Chinas ships, the former is more likely.

Judging from the layout of the 1500 frigate, its detection system must meet the ability to deal with both air and surface targets in order to provide target indications for air and sea weapons. At present, the fire control system of surface ships has been developed into a comprehensive fire control system. The level is that a fire control system can simultaneously control ship-to-ship missiles, ship-to-air missiles and artillery. Therefore, the radar is required to provide both air and surface targets. In addition, the 1500 frigate may use the DK-10 missile, which uses active radar. Guided air-to-air missiles with multi-target interception capabilities, so the detection system needs to have a stronger detection capability, especially multi-target capability, in order to give full play to the effectiveness of the missile.

From this perspective, the 1500 frigate may be equipped with a single-array rotary phased array radar similar to the SMART-S MK2. The biggest feature of phased array radar is that it realizes electronic scanning. It has fast scanning speed and flexible beam pointing. After discovering it, it can quickly adjust the beam to confirm the target. In particular, it can deal with multiple targets and can fully support the DK-10 missile. Target attack capability, multi-beam detection capability can also be used to deal with both air and sea targets. China has developed a ship-borne active phased array multi-function phased array radar and used it on the 052C\052D air defense destroyer. With the miniaturization of related technologies, it is not difficult to develop a single-array rotary phased array radar similar to SMRAT-S MK2, which can effectively increase the combat capability of the 1500 frigate.

On the whole, the 1,500-ton frigate is defined as a high-end offshore frigate. It is the flagship of the navy of small and medium-sized countries. It can form a formation, perform mobile combat missions, and can lead the formation of missiles and perform rapid assault missions. The latter provides target support and air defense barriers.

After entering the new century, the disputes between countries around the relevant marine hotspot issues have intensified, and they have strengthened their maritime strength. With the advancement of electronic technology, anti-ship missiles, fire control radars, maritime attack aircraft, patrol aircraft, data links These unattainable equipment and weapons have spread, and the Argentine Air Force has caused heavy damage to the British sea country with several super-flag attack aircraft and less than 10 flying fish missiles. Now a YAK-130 is like this. The aircraft can be equipped with phased array radars, launching anti-ship missiles such as the KH-35. Its tactical technical indicators are higher than the combination of the super flag and the AM-39 missile, so the navies of each country need to strengthen their air defense capabilities to cope with The bigger challenge is the popularity of the new century Aegis and similar ships.

However, the cost of the Aegis ship is expensive, and it is unaffordable for some small and medium-sized navies. Therefore, they choose another simple and inexpensive option. The single-sided rotary phased array radar cooperates with small air defense missiles to improve the ship's defense capability. Advances in electronic technology have made this choice possible. Take the Indonesian Navy's SIGMA frigate as an example. It uses the SMART-S MK2 single-sided rotary phased array radar. With the vertical launch of the Mika ship-to-air missile, the ship has multi-directional and multi-target interception capabilities. It has an omnidirectional interception capability and can also provide a certain air defense barrier for the missile speedboat. Of course, its defense capability cannot be compared with a special air defense ship such as Aegis, but its cost is also much cheaper than the latter. Therefore, the ship of this configuration has become a mainstream equipment for the high-end production of medium and light ships. The Russian 20380 frigate and the French chase have such high-end models.

For China, these small and medium-sized countries are the traditional market of China's shipbuilding industry. In order to better cope with competition and gain a place in the international ship market, it is obvious that such a type of high-end frigates is needed to meet the needs of users. This is why China is going to The 1500 frigates realize the vertical launch of missile weapons, especially the vertical launch of anti-ship missiles, improve the stealth capability and omnidirectional attack capability of ships, and improve the competitiveness of ships. For China's shipbuilding industry, although the 1,500-ton frigate has made great progress compared with China's previous surface ships, it still has some room for upgrading, such as further reducing the cost and cost of related systems, and implementing multi-face radar to improve the omnidirectionality of the ship. Multi-target detection capability, continue to develop compact ship-to-air missiles, achieve the goal of launching four missiles from one launching unit, and truly develop into a type of "mini Aegis" ship to further enhance the competitiveness of Chinese ships in the international market.
