Photographs posted online have shown that a new ship for the China Coast Guard (CCG) was launched on 29 May at the Huangpu shipyard in Guangzhou, southern China.

The ship, which is likely to operate around the disputed Paracel and Spratly Islands in the South China Sea (SCS), has adopted in its design a hull very similar to that of the People's Liberation Army Navy's (PLAN's) Type 054A Jiangkai II frigates, the 24th of which was under construction alongside the coastguard vessel.

While there are differences in the superstructure between the coastguard ship and the frigate, they appear to be broadly the same length and both have a flight deck and hangar to support an embarked helicopter.

With a draught of 4.4 m, the coastguard ship may displace slightly less than the Type 054A, but the numbering convention for CCG vessels indicates that it is between 3,000-4,000 tonnes. The standard displacement of the Type 054A is 3,500 tonnes.

A number of larger CCG ships are armed. No weapons have yet been installed in the latest vessel but it would be unsurprising if it is equipped with 20-30 mm guns and may also have a 76 mm gun installed forward of the bridge, as in the Type 054A. It is unlikely to carry any of the missiles installed in the frigate.

The new ship is not the first in the CCG fleet to use a warship hull. In 2015 two Jiangwei I frigates were transferred from the navy and a former amphibious landing ship was reallocated to the white fleet. The Huangpu shipyard has also constructed new coastguard ships based on the hull of the PLAN's 1500-tonne Type 056 Jiangdao-class corvettes.

The number given to the new ship also indicates that it will be allocated to the coastguard in Hainan province and is therefore likely to operate around the Paracel and Spratly Islands.

China's People's Liberation Army Navy (PLAN) commissioned its 26th Type 056 Jiangdao-class corvette on 8th June at the South Sea Fleet base at Sanya on Hainan Island. On the same day, the 25th Type 054A Jiangkai II frigate was launched at Shanghai's Hudong-Zhonghua shipyard and nine days earlier the 24th of this class was launched at the Huangpu shipyard in Guangzhou.

The latest corvette to enter service is pennant number 508, Qujing, which was built at the Huangpu shipyard. Although the commissioning ceremony took place at the Sanya base, the ship is expected to be allocated to the 26th light frigate squadron, which already operates two other Type 056 corvettes from the Yangpu base, close to the Gulf of Tonkin.

The Type 056 corvettes are believed to be replacing patrol boats of the Type 037 class, and it was reported in May that a further three of these (pennant numbers 746, 748 and 786) have been withdrawn from service. Replacements are not expected to be on a one for one basis and the planned number of Type 056s is unknown, though a further seven are currently being fitted out.

Displacing about 1,500 tonnes, the corvettes are substantially larger than the patrol boats they are replacing and much better armed. Not only do they carry four YJ-83 anti-ship missiles and a 76 mm gun, but an increasing number have an enhanced anti-submarine warfare (ASW) capability. The ASW variants are equipped with variable depth and towed sonars, torpedo launch tubes and can operate a Z-9 helicopter from the flight deck.

The first of the Type 054A frigates only entered service in 2008, but these are now the most numerous class of PLAN escorts. Equipped with a 32-cell vertical launch missile system, primarily for firing HQ-16 anti-air missiles, and eight YJ-83 anti-ship missiles, these are well armed, modern ships.

RIMPAC 2016: China deploys submarine rescue vessel to biennial naval exercise in Hawaii

Ridzwan Rahmat, Singapore - IHS Jane's Defence Weekly
16 June 2016

The People's Liberation Army Navy (PLAN) has included a submarine rescue vessel in its delegation of five ships to the US Pacific Fleet-hosted Rim of the Pacific ('RIMPAC') maritime exercise for 2016.

The country's Xinhua news agency reported on 15 June that the service has deployed the Dalao (Type 926)-class submarine rescue ship Changdao (867) on top of two surface combatants, the Type 052C (Luyang II)-class guided-missile destroyer Xian (153), and the Type 054A (Jiangkai II)-class guided-missile frigate Hengshui (572).

Also in the delegation is the Type 920 Anwei-class hospital ship Daishandao (T-AH 866), or more commonly known as Peace Ark , and the Type 903 replenishment ship Gaoyao Hu (966).

China commissions new space tracking ship

China's latest space tracking ship, Yuan Wang 7, was formally commissioned on 12 July, according to Chinese media. Source: Via hobbyshanghai.com.cn China's latest space tracking ship, Yuan Wang 7 , was formally commissioned on 12 July, according to Chinese media. Built by Jiangnan Shipbuilding, the vessel is 220 m long and displaces 25,000 tonnes. It is highly distinctive, featuring three large dish antennae around 10-12 m in diameter as well as an array of radomes and aerials.

Three other Yuan Wang-class ships (3, 5, and 6) are currently operated by the China Satellite Maritime Tracking and Control Department and are based at Jiangyin on the River Yangtze, near Shanghai.

The Yuan Wang-class ships supplement China's network of land-based tracking stations, which span the breadth of China's 4,500 km land mass.

However, tracking, telemetry, and command of satellites and other space vehicles typically require global coverage. China is constructing a tracking station in Argentina that is expected to become operational in 2017. The East Asian country also has access to facilities in Australia, Kenya, Namibia, and Pakistan.

The media reports state that Yuan Wang 7 will be used for tracking the Shenzhou-11 manned space mission planned for later this year. During previous Shenzhou launches, four Yuan Wang ships were positioned over a wide area to provide the required tracking.

The Chinese navy commissioned on 12 July its fourth Luyang III-class (Type 052D) destroyer in a ceremony at the Sanya/Yalong Bay base on Hainan Island. Source: Via Navy.81.cn China's People's Liberation Army Navy (PLAN) commissioned its fourth Luyang III-class (Type 052D) destroyer at a 12 July ceremony at the Sanya/Yalong Bay base on Hainan Island.

Yinquan (pennant number 175) joins the South Sea Fleet and the same squadron as the other three Type 052D destroyers already in service.

The ship was built at the Jiangnan Changxingdao shipyard and was launched in March 2014. The shipyard has a further five ships of the class at varying stages of construction, with the ninth yet to be launched.

A second production facility was begun in 2015 at the Dalian Shipbuilding Industry Company. To date, one ship has been launched and is being fitted out in Dalian, with two others on the slipways.

The Type 052D is the PLAN's most capable fleet escort. The distinctive square, flat panel arrays for its phased-array radar are representative of its advanced sensor fit. Its 64-cell vertical launch system can support a number of missiles, notably the HHQ-9 long range surface-to-air missile, and probably also a torpedo-carrying anti-submarine missile.

Photographs show that the class is equipped with a towed variable depth sonar.

Images show possible new variant of China's Type 094 SSBN

Richard D Fisher Jr, Washington, DC - IHS Jane's Defence Weekly
15 July 2016


This image of a what appears to be modified Chinese Type 094 SSBN reveals a sail that seems to have incorporated changes from the modified Type 093 sail. Source: Via Guancha.com After the recent revelation that China has a new variant of its Shang-class (Type 093) nuclear-powered attack submarine (SSN), new images suggest there is at least one Jin-class (Type 094) nuclear-powered ballistic missile submarine (SSBN) with similar modifications, called the Type 094A by some Chinese sources.

Revealed in Chinese online forums in late June, the modified SSN - called by some the Type 093B - features a redesigned sail that favours a rounder top area over navigation windows. The boat also features hydrodynamic improvements such as a smooth slope for the front top and the use of a small fillet at the front base of the sail that reduces flow noises.

More recently, two images of what appears to be a Type 094 SSBN featuring similar modifications emerged on the Chinese online forum Haohanfw.com. The background of one of the images also seems to imply that the boat has been deployed to the new Chinese SSBN base at Sanya, on Hainan Island, but this could not be confirmed.

There is also speculation on Chinese online forums that this is the fourth Type 094 SSBN that has been produced. Since 2008 the Pentagon's annual China military reports have estimated that up to five Type 094s could be produced.

China has great incentive to improve what are believed to be 'noisy' SSBNs. In 2009 the US Office of Naval Intelligence produced a chart showing that the Type 094, first launched in 2004, was noisier than the Soviet-era Project 667BDR (Delta III) SSBN, first launched in 1976.

Modifications to the Type 093 and Type 094 point to China's continued effort to improve its nuclear submarine force, which the Pentagon notes will lead to the third generation Type 095 SSN and Type 096 SSBN in the 2020s.

The latest Pentagon report on China's military also notes that a new JL-3 submarine-launched ballistic missile (SLBM) may be under development for the Type 096 SSBN.

The South Sea Fleet of the People's Liberation Army Navy (PLAN) commissioned on 15 July two new fleet replenishment ships at a naval port in Zhanjiang, China's southern Guangdong Province.

The vessels Honghu (hull number 963) and Luomahu (hull number 964) are the seventh and eighth Type 903/903A Fuchi-class replenishment ships, and fifth and sixth in the batch of improved Type 903As built at the Hudong-Zhonghua and Guangzhou shipyard since 2011.

They have a full displacement of over 20,000 tonnes, according to the China Military Online website, and can provide astern and alongside replenishment at sea for several different types of ships simultaneously.

The vessels can also receive helicopters for vertical replenishment operations, and are fitted with armament for self-defence against surface and air threats.

Flight deck of China's first indigenous carrier almost complete

Sean O'Connor, Indianapolis - IHS Jane's Defence Weekly
20 July 2016

Satellite imagery captured on 10 July reveals that most of the flight deck has been installed on China's first indigenous aircraft carrier (CV), the Type 001A, which is under construction at Dalian shipyard.

The Airbus Defence and Space image shows that significant progress has been made on the CV's hull since the last time construction was observed in late May 2016. For instance, between 17 May and 10 July most of the starboard and port flight deck overhanging sections were installed. The only significant flight deck component still absent was the bow's ski-jump section.

The rapid installation of significant hull components throughout the Type 001A's construction is due to China's modular construction process.

Newly Built PLAN Type 052D Destroyers Getting Fitted with Larger H/PJ-11 CIWS

Based on pictures that have been just released by Chinese spotters, it appears that the People's Liberation Army Navy (PLAN or Chinese Navy) next in-line Type 052D Destroyers (NATO reporting name Luyang III class) will be fitted with the H/PJ-11 close-in weapon system (CIWS) instead of the smaller H/PJ-12 currently fitted on existing vessels of the class.

Archive picture showing a H/PJ-11 CIWS firing aboard PLAN aircraft carrier Liaoning

The H/PJ-12 seven-barreled 30mm CIWS (sometimes referred as Type 730 which is the export designation.) is present on the first four destroyers in the series already commissioned (as well as on a few other hulls currently at various stages of completion). It is estimated that the H/PJ-12 is getting replaced by the much larger H/PJ-11 eleven-barreled 30mm CIWS (export designation Type 1130) starting with the ninth hull under construction at Changxing Jiangnan naval shipyard (near Shanghai) and the third hull currently being built at Dalian shipyard (Dalian Shipbuilding Industry Company member of CSIC - China Shipbuilding Industry Corporation).

The new H/PJ-11 appears to be an evolution of H/PJ-12. It has an increased rate of fire (local media have reported a 10,000 rounds per minute firing rate). This type of CIWS was so far exclusively fitted on the Liaoning aircraft carrier and the latest few Type 054A Frigates. Chinese TV reported that following studies and testing, H/PJ-11 is able to intercept incoming anti-ship missiles up to a speed of Mach 4 with a 96% success rate.

There may be other modifications or upgrade on the latest Type 052D Destroyers (or this may even indicate a new batch or mod.) but this is impossible to confirm at this time. The installation of the larger CIWS shows that there are plenty of growth margin (in terms or weight, space and power supply) on this type of destroyers.

Type 052D Destroyer Kunming (172), first ship of the class, underway (note the H/PJ-12 CIWS behind the H/PJ-38 130mm main gun)

At least 12 Type 052D Destroyers are expected to be built for the PLAN, most of them (80%) by Changxing Jiangnan naval shipyard near Shanghai (the rest at Dalian shipyard in North East China). The PLAN recently commissioned the fourth unit with the South Sea Fleet.

The Type 052D Kunming class (Nato designation: Luyang III) is the latest generation of guided-missile destroyer (DDG) of the Chinese Navy. It is based on its predecessor, the Type 052C DDG and likely shares the same hull. However the Type 052D incorporates many improvements in terms of design as well as sensors and weapons fit. This new class of vessel is considered as the Chinese equivalent to the American AEGIS destroyers.

Alguns números que achei interessante sobre o 052D o AB chinês.


A primeira questão seria que o navio diz conseguir velocidade máxima de 30 nos.
A segunda seria sobre a capacidade real do radar.


O 052D tem 2 turbinas a gás e 2 motores a diesel, as 2 turbinas a gás tem potencia máxima de 76.000hp os 2 motores a diesel tem potencia máxima de 16.000hp somados são 92.000hp porem ele utiliza o sistema CODOG então somente pode operar ou os motores a diesel ou as turbinas para se locomover não da para utilizar os 2 ao mesmo tempo.

O 052D desloca 7.500t com 76.000hp a 30 nos segundo os chineses.


Um antigo DDG japonês classe Hatakaze desloca 6000t com 72.000hp a 30 nos.

Dados do 052D
Comprimento:156m
Largura:18
Deslocamento:7500t
Potencia:76.000hp
Velocidade:30 nos

Hatakaze
Comprimento:150m
Largura:16.4m
Deslocamento:6000t
Potencia:72.000hp
Velocidade:30 nos

Como que o 0D52 consegue chegara 30 nos sendo que a diferença de tamanho, largura e peso são maiores que o Hatakaze, mas com potencia similar.

Agora a parte do radar a classe 052D se destaca pelo radar AESA que os chineses dizem ser melhor que o Aegis das ABs, este tipo de radar consome uma grande quantidade de energia elétrica, a classe Kongo por exemplo além das 4 turbinas totalizando 100.000hp para propulsão tem mais 3 turbinas a gás 501-K14 que gera 10.000hp somente para alimentar os sistemas elétricos do radar.

Os 2 motores a diesel do 052D gera 16.000hp são os mesmos utilizados na classe 054A de 4000t de deslocamento porem a classe 054A utiliza 4 motores a diesel totalizando 32.000hp a 27 nos.

Analisando um pouco os dados quando o 052D utiliza os 2 motores a diesel para baixa velocidade muito provavelmente não tem energia elétrica suficiente para operar os radares, e se utilizar as turbinas com o radar ligado nem sonhando que o navio consegue navegar a 30 nos.

Que má vontade com os chineses hein?

Quando o assunto é velocidade de um navio potência não é tudo, o Ticonderoga americano, por exemplo, tem um total de 80 mil hp para mover 9800 tons a 32,5 nós.

Claro que não daria para fazer isso com 20hp, mas dois navios de tamanho similar chegarem a mesma velocidade com uma pequena diferença de potência é algo bem aceitável.

Não sei se os 052D possuem algum gerador auxiliar, acredito que faz mais sentido utilizar os motores a diesel para isso, assumindo que a potência máxima dos radares seria necessária em combate os 16.000hp (dos quais eu acredito que não mais de 8.000hp - 6MW - sejam usados por radares e demais eletrônicos do navio) estariam disponíveis para esse fim.

E a comparação foi com as AB, elas tem uma configuração similar as Kongo, com 3 geradores, mas não precisa da potência dos 3, um deles é redundante, 5MW de dois geradores é suficiente para os radares, e por falar nos radares, no caso da AB eles já são meio antigos, são sistemas PESA, não é impossível que radares mais modernos tenham mais capacidade com a mesma potência.

Eu sei onde quer chegar com essa comparação, mas novamente, essa relação entre deslocamento, potência e velocidade não é direta, inclusive o comprimento do navio influencia, de qualquer jeito, a potência tem mais relação com aceleração do que com a velocidade final em si (por falar na velocidade final, realmente faz diferença se é 27, 30 ou 33 nós?).

Não é ma vontade não é apenas desconfiar porque as vezes alguns números que eles divulgam não batem e fica difícil entender, se sabe por exemplo que a classe 052C anterior tinha problemas no Radar Pesa que sobre aqueciam os sistemas por isto os radares da classe D foram modificados.


Radar do 052C e do 052D

Se o navio tem outra fonte de energia auxiliar que não foi divulgado ai tudo fica tudo explicado.

http://news.searchina.net/id/1595501?page=1
Como eles divulgam dados e não se sabe o que é verdade, resta apenas especular a própria mídia chinesa diz que os navios tem potencia inferior aos americanos por isto são mais lentos, inclusive estes dados de comparações de potencia/radar vieram de fontes chinesas eu estou procurando e posto aqui quando encontrar.

https://www.youtube.com/watch?v=sdhlJaQPiAg
Por outro lado tem noticias ufanistas do tipo, 052D ser superior a classe Ticonderoga.

Para mais uma comparação a classe Akizuki utiliza radares Aesa.

Comprimento:150.5m
Largura:18.3m
Deslocamento:6800t
Potencia:64.000hp
Potencia auxiliar para o radar 3 turbinas a gás M1A-35: 7.200kW
Velocidade:30 nos

O radar desta classe que utiliza 8 antenas, porem pequenas foi otimizado para utilizar misseis ESSM que são de médio alcance, foi dito que para esta classe poder utilizar misseis da classe SM-2 teria que ampliar a capacidade de geração elétrica para o radar, se 7.200kW não é suficiente para alimentar uma antena Aesa para longo alcance, como eles deram o pulo do gato, é difícil acreditar que os chineses estão na frente dos japoneses e americanos que iniciaram o desenvolvimento de radares Aesa nos anos 70/80.

Outra coisa geralmente quem desenvolve antenas Aesa mostram seus módulos T/R como sinônimo do avanço tecnológico da nação eles nunca mostram nada apenas diz que é isto [...] e fica em aberto acreditar ou não nas informações neste ponto por exemplo os russos são muito mais abertos.

Quanto a essa última parte, concordo 100%.

Só estou dizendo que as alegações chinesas não são impossíveis, claro, justamente pela falta de transparência dos chineses é dificil confirmar as informações.
