Jianghu-V Type 053H1G
The 053H1G is called the “Jianghu-V” class in the West. This type of ship was built specifically for the South China Sea patrol. In the early 1990s, the situation in the South China Sea began tough. Therefore, China needs to strengthen the management and control of the relevant sea areas. However, at that time, the South China Sea Fleet had limited large and medium-sized surface ships, and it was difficult to perform patrol and warning missions in the relevant seas for a long time. Therefore, the South China Sea Fleet had to dispatch light ships such as 037 hunting submarines. Nansha's patrol mission, because the 037 type submarine has small tonnage, low freeboard, poor wind and wave resistance, poor wave resistance, and limited space and self-sustainability. When the officers and men perform tasks, the environment is difficult, so the South China Sea Fleet urgently needs an economy. Cheap medium-sized ships perform patrol missions in more remote areas such as Nansha.
Although China's second-generation surface ships have already begun construction, it is difficult to build and equip the troops in large quantities, taking into account the production capacity of the relevant shipyards. At the same time, considering the strength of the relevant naval vessels, it is only necessary to carry out appropriate training for active ships. Improvement can meet the needs. This is the 053H1G frigate. From the related pictures, the 053H1G adopts the line type and power system of the Type 053 frigate. It only makes appropriate improvements to the ship according to the operational environment in the new period. Its improvement project Including: changing the original open superstructure to a closed structure, using central air conditioning and collective nuclear biochemical pressure defense system to adapt to the humid and hot climate of the South China Sea; redesigning the chimney structure, the exhaust opening is facing the horizontal sides, reducing The heat signal radiated from above. This unique chimney has also become the main external feature of the 053H1G.
The main weapons of the 053H1G are two ENG-2 double-mounted 100mm guns, four PJ-76A double-tube 37mm guns, and two 75-type 5-unit anti-submarine rocket launchers. Compared with the new artillery, the 053H1G It is still equipped with the dual-mounted launcher of the upstream-1 anti-ship of the early 053 frigate.
The 053H1G is equipped with the ZKJ-3A tactical data processing system, which connects the radar, sonar, electronic warfare and navigation systems on the ship through a data bus to form a unified tactical situation map. It can control the ship's anti-ship missiles, artillery and anti-submarine rockets, and has a good comprehensive combat capability. Considering that the ship needs to perform front-end warning missions, it is equipped with a 517-type air-to-air detection radar. The radar antenna is installed on the top of the chimney structure.
On the top, avoiding the exhaust ports facing the two sides, can avoid direct baking by hot exhaust gas, improve the life and reliability of the system, 517 radar works in Mibo, according to relevant information: 053H1G type equipment should be 517H-2 Radar, its detection range is more than 300 kilometers, but due to the working wavelength, the detection accuracy is low, so it is only suitable for remote warning tasks, and can not be used for command and guidance. Other detection equipment includes: 360 air-to-air, sea-detection radar for search and tracking of sea and low-altitude targets, fire control systems; including 343 fire control radar, used to control 100 mm guns, 347G fire control radar and photoelectric fire control system, used to control JP76A double-tube 37mm automatic gun, electronic warfare system, considering that the ships of neighboring countries have also achieved missileization, the 053H1G frigate is equipped with a relatively complete electronic warfare system, including Radar warning ring, active interference and chaff rocket launching system, domestic SJD-5 IF shell sonar equipped with sonar system, considering the tonnage, power supply capacity and cost of the ship, 053H1G is not equipped with towed sonar.
The first 053H1G was started at the Huangpu Shipyard in June 1991. It was delivered to the ship in May 1993 and was named Zigong (558). From 1993 to 1996, the Chinese Navy built six 051H1G frigates, all of which were delivered to the South China Sea Fleet. service. After entering the new century, according to the development of the situation, the strength of the naval vessels of the relevant countries has been further enhanced. These ships are equipped with advanced anti-ship missiles such as the harpoon, flying fish and KH-35. In this case, China The 053H1G was upgraded. According to the pictures published by the relevant media, its upgrade projects include: changing the stealth shell for the ENG-2 gun, removing the 517-meter-meter air-to-air warning radar, and replacing it with a spherical satellite. The communication system replaced the original upstream-1 anti-ship missile with two 4-pack eagle-83 anti-ship missiles, and its combat capability was further enhanced. However, the original design of the ship was relatively long-term and there has not been much improvement.
