Ship in a big country: the Chinese Navy frigate, the secret development of the future
( as 891-ship plan testing schedule has been filled, an estimated 892 laser near Artillery on the possibility of bigger ship )
before the mid-1990s, China’s relatively weak strength of the Navy surface ships, the lack of independent research and development capabilities. Ten years ago, the Chinese navy has introduced from Russia was the world’s advanced level modern class large missile destroyer, which was ground-breaking significance of the Chinese Navy. But for a long period of time, Russia’s modern class are still the largest of the large Chinese Navy surface combat ships, independent research and development in China has been very difficult to break.
recognized with a huge gap between the world’s naval powers, the Chinese catch up. In 2004, China completed construction of 171 ships the next four years, the construction of Chinese frigate on the temporary one-paragraph report. In this four-year R & D department has been recorded in the summary 170, 171 and ship in use of the data.
Since 2004, the R & D departments and agencies has been to improve a variety of shipboard equipment to improve the performance of the next generation of warships.
improve power plant
from 2004 to 2008 of the past four years, the domestic gas turbine has been improved, Until early 2008, was completely established, it is because American-made gas turbine digested LM2500 gas turbine (112, 113, No. 052 destroyers equipped) technology to gas turbines used for domestic imitation Ukraine GT25000 improved models (170, 171 number on the GT25000 gas turbine equipped with Ukraine’s domestic generic models).
on a destroyer in the 052B. Four domestic imitation GT25000 Gas Turbine 93 MW in total power actually about (the Japanese destroyer Atago-class air defense destroyers and South Korea KDX3 Although there are tons of full row, it was the level of 70 MW of total power). 2008 latest model made with four gas turbines up to 98 MW total power, smaller (greater power density), start faster, to reduce noise in a lot of low-frequency component (because the ocean is easy to spread low-frequency noise characteristics , leading to low-frequency noise emitted hull easily be the enemy sonar). This high level of power can be 10 000-ton destroyers to maintain cruising speed of 35 knots on. At the same time using high-temperature alloy with directional solidification and means to improve gas turbine gas-cooled hollow turbine blade life.
improve Haiphong 730 fire control computer chip and control software, steering motor, improved the sensitivity of coastal 730 .
170,171 coastal defense ship more than 730 pieces of fire control computer use ARM9 chip parallel data processing, 730 Su Shebao new coastal development with the National Defense University’s “Xunteng” embedded processor (YHFT64- 3 “FIT” sister miniature), “Xunteng” (MGXT64-2) in a 6-stage pipeline. Increase the pipeline design to improve the clock frequency and the parallel processing capabilities, and its single-processor GPP speeds up to 390MHz, 6-stage pipeline processing can be allocated for each instruction to 6 clock cycles, each clock cycle at the same time There are six commands in the execution. ), “Xunteng” (MGXT64-2) is the ARM9 processor clock frequency of 1.8 to 2.2 times. 730 new Haiphong same computer using a multi-satellites “Xunteng” (MGXT64-2) chip as the computer processing unit. In the language of fire control software to improve the use of ada95 original C + + language, optimized for parallel processing algorithm to improve the multi-target handling capability. Improved use of a new coastal defense turned 730 motor, the motor uses rare-earth permanent magnetic materials and other materials to improve the rotation of the motor speed and working life.
other new 10,000-ton destroyer, FL-3000N nearly 730 coastal defense system and can have a separate fire control computer, can also be ship’s fire control system combined control, collaborative goal to intercept the enemy. Joint fire the ship’s multi-threaded parallel processing computer system can guide the allocation of 730 FL-3000 and the coastal intercept incoming targets, to maximize the probability of intercept hit. FL-3000N-guided missile with an infrared imaging methods, performance, and the United States, “Ram” very short-range air defense missiles, especially for supersonic anti-ship missiles to intercept, so the use of FN-3000N and 730 short-range defense systems into an integrated defense system, can greatly enhance the new drive for low-altitude, fast target intercept capability.
According to reliable sources, the new drive the next generation of 10,000 tons, and is likely to install high-power microwave weapons , the high power of such weapons in the existing jammer. By guidance radar to guide for incoming anti-ship missiles, 10 km away goal for the RF electromagnetic pulses, ablation guided anti-ship missiles off the head of an enemy sub-components. 10 to 20 kilometers can play the role of jammers, the use of appropriate high pulse repetition rate, bandwidth and pulse shape, it will be much higher than existing jammers damage effects. Large vessels in the weight of the microwave weapons, space and power constraints make less. Therefore, the Navy-type microwave weapons could be launched in the coming new-ton destroyers first put into use.
on whether the next generation of laser near Artillery ton destroyer , depending on the unit progress of miniaturization of the module, the current military laser near Artillery in the study, the total volume of large modules, the possibility of a short time on the ship is relatively small. It is said that the second half of next year on the original plan to test 891 test ship, but its slow progress in miniaturization of the module, combined with 891 other Navy ship dedicated test equipment trial schedule has been filled, so the laser is actually testing anti-ship near the test date continue to delay.
10,000-ton destroyers in the next generation will make the sea red 9 on the launcher to change to something like the U.S. Navy (USNavy) MK-41 vertical launchers square layout, so increased sea red 9′s payload. Not only anti-aircraft missile, also capable of launching anti-submarine missiles or land-attack cruise missiles. 10 land attack cruise missiles that sword will be on the ship, to enhance the new destroyer’s ultra long-range land-attack capability. Sword 10 land attack cruise missiles on combat ships will make the destroyer performance to a new level, (the other: It is reported that 093 nuclear-powered attack submarines will also be modified, the installation of sea-based version of the sword 10 cruise missiles ).
latest build another 7,500-ton destroyer, the sea or the HQ-9 launchers could launch with a circular cylinder 171 is similar, limited by the size, not the use of improved square layout. Another 10,000-ton destroyers will use the new square layout of the HQ-9 sea launcher.
in anti-ship missiles, 172-ton destroyers and above, YJ 62 missiles will continue to equip, YJ-62 350-km range is greater than the United States, Japan, Taiwan’s Harpoon (also known as “Harpoon”), 130 km range anti-ship missiles, as China’s more pointed, Compass satellites, early warning aircraft in service, they can already play a range of advantages of these missiles, in order to achieve long-range goal of pre-emptive attack, the use of Eagle -62 Another advantage is that you can use the system to use automatic flight control system the target areas of digital maps, the use of a turning point for the missile flight path to avoid obstacles (such as hills, tall buildings) , attack the hills, high-rise behind the goal, the U.S. Harpoon-BLOCK2 batch you can use this ability to attack off the coast about 100 kilometers of the target, Eagle -62 range than the spear-BLOCK2 to be far more So if you carefully select the relevant route, could be more strange to attack enemy targets, to use as a short-range cruise missiles, the new drive for the 7500-ton level (also including the previously constructed 170, 171), because now Some common vertical launch system is poor, so a short time is unlikely to carry land attack cruise missile, if we can play the other side of Eagle -62 attack, could offer a simple, convenient transitional choice.
Eagle -62 there is still much need to improve and enhance the place, especially for performance and reliability requirements of a very high micro-turbo-fan engines. Eagle -62 volume, launch weight and the weight of the warhead missiles with almost 10 sword, but because of turbojet engine fuel consumption, coupled with the internal structure of the design led to fuel loading rate is not high, the eagle and the sword hit the range 10 -62 compared to the significant gaps, so you can be part of the long-range land-attack YJ-62 turbojet engine, turbofan engines replaced, to improve their range of attacks on ground targets. Of course, attacks on maritime targets YJ62 turbojet engine can keep using the same volume of small turbojet engine thrust greater than the turbofan engine, this could make the missile faster.
final say about the new 172-ship sea trials about two months later, is still within the pipeline laying, 172, or 7500-ton ship the other, form with 171 ship will not be much change, but the internal electronics, fire control, radar performance was greatly improved. 172 ships will be the last one 7500-ton other warships, 172 ships, the Chinese Navy will usher-ton destroyers. Having said this, I suddenly remembered 115 years ago that sea, Liaodong Peninsula just back from his trip yesterday, standing on the beach, watching the vast sea and sky, filled with emotion. Remember the old saying: “ green and sea fog, above the sea, the state-owned War – Remembrance Jiawu pain “, feud Japan’s determination only through the Navy’s battle to end!
