Type 056 Jiangdao is a new class of stealth corvettes being built by four Chinese shipbuilders to replace the ageing Type 037 fleet of the People’s Liberation Army (PLA) Navy.
Type 037 corvette
The Type 037 corvette is a series 400-500 ton corvette type classes in service with the Peoples Liberation Army Navy. Unlike western navies, the Peoples Liberation Army Navy does not have dedicated patrol boats in its inventory. Instead, a large variety of corvette type classes, in the form of missile boats and submarine chasers fulfill the tasks of patrolling China’s territorial waters. The Egyptian Navy operates eight vessels.

The PLA Navy plans to procure 20 corvettes in the first batch. It currently operates ten Type 056 ships, while the remaining vessels are in various stages of construction.
The Jiangdao Class corvette can be deployed in patrol, escort, search-and-rescue, surveillance, exclusive economic zone (EEZ) protection, electronic warfare (EW), fishery resources protection, anti-aircraft warfare (AAW), anti-submarine warfare (ASW) and anti-surface warfare (ASUW) operations.
Construction of Jiangdao Class corvettes
The stealth corvette class is under construction at Wuchang, Huangpu, Hudong-Zhongua and Liaonan shipyards.
The lead ship in class, Bengbu (582), was rolled out in May 2012 and began sea trials in November 2012. The vessel entered service with the East Sea Fleet in February 2013. The second frigate, Huizhou (596), was launched in June 2012 and commissioned into the Hong Kong Garrison in July 2013.
The third vessel, Meizhou (584), was launched in July 2012 and deployed in the South China Sea Fleet in July 2013. Datong (580) was rolled out in August 2012 and entered service with the North China Sea Fleet in May 2013.
Shangrao (583) was launched in August 2012 and entered service with the East Sea Fleet in June 2013. Qinzhou (597) was launched in August 2012 and commissioned into the Hong Kong Garrison in July 2013.
Baise (585) was launched in October 2012 and entered service with the South China Sea Fleet in October 2013. Yingkou (581) was launched in November 2012 and deployed in the North China Sea Fleet in August 2013.
Ji’an (586) was rolled out in February 2013 and commissioned into the East China Sea Fleet in January 2014. The tenth frigate in the class, Jieyang (587), was launched in January 2013 and entered service with the South China Sea Fleet in January 2014.
Quanzhou (588) and Suqian (FFG 593) were launched in June 2013 and November 2013 respectively.
Design and features of Type 056 corvettes
The Type 056 corvette is the first Chinese modular warship that can be deployed as an offshore patrol vessel or a multi-role frigate. The vessel features stealthy hull design integrating sloped surface and compact superstructure.
The type 056 class fills the gap between the 4000-ton 054A class frigate and 220-ton 022 class FAC. As of now, at least nine other 056s have already been launched by the four shipyards building them. The overall number of this class is expected to be between the final count of 054A (probably around 20) and 022 (around 80). They are expected to replace the 10 Type 053 class Jianghu frigates currently serving in the South China Sea Patrol flotilla and the close to 50 Type 037 class missile boats.
In many ways, the type 056 hull is based on the Pattani class OPV that China built for Thailand from 2005 to 2006, although more signature reduction work is done such as the shielding of the funnels. Source usni.org

Royal Thai Navy Pattani class OPV
HTMS Pattani (511)
His Thai Majesty’s Ship (HTMS) Pattani was the first of two such vessels ordered from China Shipbuilding in 2003. The classification of these ships is confused, as they are sometimes called Offshore Patrol Vessels (OPV), but possibly they are too heavily armed for that appelation, and frequently called frigates, but possibly their displacement is closer to that of a corvette. The Thai Navy’s Pattani-class OPV bears a resemblance to the subsequent Chinese Type 056 corvette / light frigate, though the later is up-gunned relative to the the Thai OPV, with four YJ-3/C803 ASM and a FL-3000N RAM launcher aft, while the former has a much taller superstructure.
The Pattani is an interesting example of how Chinese hulls can be integrated with Western, sensors and weapons systems. Not much has been heard about its performance or build quality, but both were said to be better built than the older Chinese frigates.

YU-7 ASW torpedo
The Yu-7 is a lightweight torpedo of Chinese origin. Since 1984 China tried to copy and later produce under license the US Mk 46 torpedo. This proved to be difficult and a batch of Italian A.224S torpedoes was ordered and the two designs were mated. An electrically powered Yu-7 offspring called the ET-52 was developed and put into service before the development of the Yu-7 was finished.
Type-054A Frigate Anti-submarine Exercises – Image: errymath.blogspot.com
The Yu-7 is a mixture of the Mk 46 Mod 1 and Mod 2 with various components from the A.224S torpedo. The Yu-7 retains the complex Otto fuel engine which provides it with a better performance than the electrically powered ET-52. The layout is conventional with the seeker in the nose, the warhead in the middle and the fuel and engine at the rear.
The Yu-7 uses a combination of passive and active acoustic guidance. It is believed that the Mk 46 seeker design is retained but several components have been replaced by those from the A.224S.

The P18 corvette is the export version of the Type 056. The P18 is advertised as displacing 1800 tons, with a 95 m. length and a 12 m. beam; the powerplant is two MTU 20V 4000M diesel engines, for a maximum speed of 25 knots (46 km/h); armament may include a 76 mm. gun, two 30 mm. cannons, up to eight anti anti-ship missiles, and two triple torpedo launchers; a medium-sized helicopter may be carried.
In 2014, the P18 was reportedly considered by Kazakhstan to fill a requirement for up to nine ships.
In late-2014, Argentina reportedly agreed to purchase five P18s, two to be built in China, and the remainder to be co-produced in Argentina. The ships would be called the Malvinas-class, and have towed array sonar and an enlarged landing deck to handle Sea King helicopters. Each ship may cost US$50 million.
The C13B corvette is the P18 variant under construction for the Bangladesh Navy. The corvette displaces 1330 tons and is 90 m. long. It is armed with a H/PJ-26 76 mm. gun, C-803 anti-ship missiles, FL-3000N SAMs and Two H/PJ-17 30mm remote controlled gun turrets. The C13B lacks sonar and ASW weapons. Like the Type 056, there is a helicopter pad but no hangar. The corvette has a reported speed of 25 knots (46 km/h).

Two corvettes were ordered from Wuchang Shipyard in Wuhan,reportedly in October 2012. Shadhinota (F111), the lead ship, was launched on 30 November 2014. Shadhinota and Prottoy were undergoing initial sea trials in early July 2015, but were not yet completely fitted out. Both were expected to enter service in December 2015. Both ships arrived in Chittagong, their home port, on 10 January 2016.
Two more corvettes were ordered in July 2015 and they are under construction now.
The P18N offshore patrol vessel (OPV) is the variant operated by the Nigerian Navy. The P18N displaces 1800 tons, is 95 m. long, has an endurance of 20 days, a maximum speed of 21 knots (39 km/h) and a range of 3,000 nautical miles (5,600 km) at 14 knots (26 km/h). It has a crew of 75. Armament is reportedly a single NG-16-1 76 mm. gun with a TR47 fire-control radar, two 30 mm. guns, and two 20 mm. guns. The class has an Oil Support Recovery System to combat oil spills. Unlike the Type 056, the P18N has a helicopter hangar.
NNS Centenary (F91)
Nigeria ordered two P18Ns from CSOC in April 2012 for US$42 million each. The first was slated to be completed in China, with the final 50–70% of the second being completed at the Nigerian Naval Shipyard in Port Harcourt; CSOC was contracted to upgrade the shipyard to facilitate this.
NNS Centenary (F91), the first P18N, was built at the Wuchang Shipyard in Wuhan. It was launched January 2014 and completed trials in October 2014. Centenary left China in December 2014 and arrived in Lagos, Nigeria in February 2015; it was commissioned the same month. Delivery was originally expected in mid-2014.
The second OPV, NNS Unity (F92), was reported in February 2015 to be undergoing outfitting at Wuchang, and was expected to be delivered in 2015. Nigeria had originally expected to receive it in mid-2014 for completion at Port Harcourt.
