DDG-X [Area Defense Project]
The PLAN seeks to push its maritime defense perimeter further seaward. This change in operations would require newer, more modern warships and submarines capable of operating out to the Ryukyu Islands and into the South China Sea. At these extended ranges, the platforms would have to be better armed to enable defense from all methods of attack. The Navy has been conducting research and acquiring foreign technology in an effort to improve the broad range of naval warfare capabilities; it also is acquiring new classes of ships that would be better suited for operations out to the limits of the East and South China Seas.
Through the end of the 20th Century the PLAN continued to have long-standing concerns about its capability to engage enemy aircraft, cruise missiles and precision-guided munitions. This problem is becoming more significant as the Navy strives to operate away from the protection of land-based air defenses. PLAN surface combatants had a limited, and primarily self-defense, anti-air warfare (AAW) capability. Only some of its destroyers and frigates are outfitted with SAM systems; the others were armed only with AAA and possibly man-portable air defense systems.
In addition, PLAN warships lacked the modern air surveillance systems and data links required for area air defense missions. The combination of short-range weapons and lack of modern surveillance systems limits the PLAN to self-defense and point-defense anti-air warfare only. Consequently, except in unusual circumstances, no PLAN ship is capable of conducting air defense of another ship. Additionally, the PLAN could not reliably defend against either current or projected anti-ship cruise missiles (ASCM).
This changed with the advent of the Type 052C Luyang II, the first of which commissioned in 2004. Type 052D, the first of which commissioned in 2014, is a newer design than the DDG-57 Arleigh Burke, but both vessels are very good looking and capable. However, there are characteristics of the Burke IIA that are noteworthy and important, despite aesthetics. The Burke IIA has 96 VLS cells the Type 052D has 64. The Burke IIA carries two helicopters, the Type 052D carries one. The slope on the side panels of the Burke IIA provide better radar dispersion, because they are sloped more, particularly above the main deck, and also with the "raked" mast. The bow Sonar on the Burke IIA is much more powerful than that on the Type 052D. The wider beam on the Burke IIA allows for better handling, particularly in rough sea states. The AEGIS system and cooperative engagement capabilities on the Burke IIA are very well known, understood, and proven. The effectiveness of the new APARs and the combat system on the Type 052D remain unknown.
There has been some speculation that a new design would be constructed with a 10,000 ton displacement. This might be equipped with the "Rif" Naval S-300 system, which utilizes a single Tombstone phased array radar, in a vertical launching system (VLS).
Since late 2012, Chinese military forums began discussion of a new Type 055 missile destroyer. Sources reported top161.cn that the design of the destroyer has been completed. The destroyer was to have better stealth design with low noise, infrared and electromagnetic characteristics. It was said to have a new generation of multi-module active phased array radar with a range of 600 km able to monitor and control several hundred targets and automatically distribute targets to various combat units (including the destroyer itself and other combat units), and a joint combat data distribution transmission system similar to the Link-16 of US Navy. Its firepower was said to be 3 to 5 times greater than that of US Arleigh Burke class destroyer and 2 times greater than that of US Ticonderoga class cruiser, although it was unclear what this was supposed to mean. These reports claim that a Chinese aircraft carrier combat group would contain one carrier, two 055 destroyers, four 052D destroyers and four 054A frigates.
By one observer concluded as of mid-2013 that "No doubt PLAN would not stop at Type 054D... and would carry on advancing if economic and politics continue to be stable and there are no major problem happening internally. But up till now, unless there are official sounding or anyone who could provide good solid source and references, it seemed like alot of hot air are around and alot of fanboys dream."
China Defense Blog wrote on 07 April 2014 that "The mockup of the CV LIAONING was built at Wuhan in late 2009, and the actual ship entered the fleet in 2012. Using this same timeline we might expect the keel of the new cruiser to be laid in 2015 with a 2017 commission date." Totoro's April 2014 dimension estimates at China Defense Blog of 163m long, while exemplary, are only very preliminary, and there is a train of thought that the 055 may end up being some 186m long with a 23m beam.
Jeffrey Lin and P.W. Singer wrote on 01 May 2014 that "New photos of the work ongoing outside of Wuhan, China, show that the engineers and scientists of the People's Liberation Army Navy (PLAN) are making fast progress in completing the 055 guided missile cruiser's (CG) electronics testing mockup... The main feature of the 055 CG is its Type 346 series of radars, of which four are to be mounted on the forward superstructure around the bridge. ... The newest photos also show that the integrated mast (the grey colored tower on top of the superstructure) is taking shape. The integrated mast above the bridge will hold smaller but equally important radar, in addition to communications and electronic jamming equipment. Compared to traditional masts, integrated masts are stealthier by enclosing all the antennas and supporting structures. While not as large as the Type 346 radars, the X band radar mounted in the middle of the integrated mast offers better resolution than the Type 346, which is important for target identification and discrimination (i.e. identifying fighter aircraft against decoys and jamming)."
In the construction of the Chinese Navy type 055 large missile destroyer with a displacement of over 10,000 tons (compared with 052D displacement of only 7200 tons), ship type is used to reduce the electromagnetic characteristics, infrared characteristics and noise characteristics of stealth design, self-sustaining force has fast speed, high endurance, long and good global airworthiness of. Type 055 large missile destroyer has a powerful integrated operational capability of the single ship, with a far, medium and near three layers of soft and hard weapon early warning and defense network and attack firepower network. With air defense, anti submarine, anti-ship and land attack ability, comprehensive ability to stereo group.
Li Jie, researcher with the PLA Naval Military Academic Research Institute, expressed 24 February 2017 that information from various sides showed that the Type 055 guided-missile destroyer boasts outstanding overall performance and represents the highest level of Chinese surface vessels today. However, Li said, it's hard to compare the Zumwalt-class destroyer with Type 055 because they have different combat functions: the former is responsible for major fire strike against targets and facilities, while Type 055 undertakes multiple combat functions and is also responsible for escorting aircraft carrier battle group.
Some media reported that the development of Type 055 destroyer is a milestone for the PLA Navy. It is even more significant than the development of Type 001A aircraft carrier. According to Li Jie, Type 055 destroyer has a full load displacement of 13,000 tons and will be China's largest destroyer if commissioned.
Second, it has outstanding stealth performance thanks to various stealth designs and comprehensive stealth means. Its body also adopts stealth design, and the radar has a very small cross section with low infrared radiation, small electromagnetic radiation and low noise.
Third, it is equipped with a number of weapons. Being able to carry more than 100 vertical launching missiles of various types at the same time, including anti-ship missile, air-defense missile, anti-submarine missile and even long-range ground-attack cruising missile, Type 055 destroyer can attack targets 1,000-2,000km away, indicating a massive enhancement of ground attack capability.
Meanwhile, the 130mm single-barrel shipboard main-gun is strong at short-range ground attack and at attacking other targets as well. Type 055 also has anti-missile capability.
Fourth, it adopts double-band radar and has S-band active phased array radar (APAR) system and X-band small phased array radar system, which result in a strong capability of detecting medium-range and short-range targets.
At last, Type 055 is very good at capturing and processing information and can integrate various information receiving from the space, air, water surface and underwater.
The PLA Navy has decided that aircraft carrier battle group will be the main direction of surface vessel development, so new vessels will all be developed based on the needs of the battle group, including the design and construction of Type 055 destroyer. "Type 055 guided-missile destroyer carries medium-long-range and medium-short range air-defense missiles, which can significantly improve its overall air defense capability. It also has a strong anti-submarine capability, so it is much more able to protect aircraft carrier battle group than the Type-052D destroyer currently in service", Li Jie said.
"In addition to escorting aircraft carrier battle group, Type 055 destroyer is also able to head up an independent multi-purpose marine combat taskforce and carry out air-defense, anti-submarine and anti-ship missions," he added.
This wasn't the first time that western media call China's Type 055 guided-missile destroyer a cruiser. Regarding this, Li Jie replied that in terms of tonnage alone, Type 055 is larger than many serving cruisers. America's Ticonderoga-class cruiser, for instance, has a full load displacement of less than 10,000 tons. As a matter of fact, destroyer and cruiser aren't that different today, and most countries don't even develop cruiser anymore.
