Recently, the China Strait held a ceremony in Guangzhou for the handover and entry of the "Hulun Lake Ship," and the entry of the ship into the column has completed the last piece of the puzzle of China's aircraft carrier formation, laid a more solid equipment foundation for the sea ships to move towards the deep blue, and marked a new leap in the sea's ocean-going support capability.

In recent years, China's naval forces have developed rapidly, and with the gradual improvement of the equipment structure, the China Navy has taken advantage of various opportunities to carry out actual combat exercises on many occasions, and its comprehensive strength has been continuously enhanced.

Aircraft carrier supply ships in Asia

According to reports, the "Hulun Lake Ship" is a Type 901 comprehensive supply ship independently developed by China and of the world's advanced level, which can provide maritime companionship for China's aircraft carrier formation and far-sea mobile formation. It has made breakthroughs in a series of key technologies such as the development of new maritime supply devices and the overall design and construction of large supply ships. With a length of 239.5 meters and a width of 30.5 meters, the "Hulun Lake" is a 48,000-ton aircraft carrier supply ship, 1.6 times larger than the existing large supply ship "Qinghai Lake" (30,000 tons) in the China Sea, surpassing the Japanese Self-Defense Force's comprehensive supply ship of similar size to the "Qinghai Lake" and becoming a comprehensive supply ship in Asia. It has been reported that the fuel transportation capacity of the "Hulun Lake Ship" has been greatly increased compared with that of previous aircraft carrier supply ships, and it can fill the fuel tanks of China's first aircraft carrier, the "Liaoning," 3.3 times, and thus the combat radius of the "Liaoning" has been increased to 4,684 nautical miles (about 8,675 kilometers), expanding to Hawaii in the United States. Prior to this, China had a total of 9 supply ships, namely Gaoyou Lake, Qiandao Lake, Chaohu Lake, Fuxian Lake, Dongting Lake, Qinghai Lake, Honghu Ship, Luoma Lake Ship, and Dongping Lake Ship, but the tonnage and speed were not as good as the "Hulun Lake Ship".

The world's air defense destroyers

The launch of the lead ship of the Hai-055 destroyer on 28 June marked a significant milestone in the history of China's maritime development, according to media reports. The Type 055 is one of China's first 10,000-ton destroyers, and its hull can accommodate a larger flight deck and twin hangars than the Type 052D destroyer, and can carry two helicopters at the same time. In addition, the ship is also equipped with new anti-aircraft, anti-missile, and anti-ship systems, and the number of launch units of the vertical launch system has been increased, and it has better combat capabilities. It has been learned that the Type 055 destroyer, as the "escort" of the aircraft carrier formation in the China Sea, surpasses the Zumwalt-class destroyer of the United States and the planned Arleigh Burke Type III destroyer, and is the most powerful air defense destroyer in the world.

According to some analysts, the Type 055 destroyer and the Type 901 supply ship have really provided security for the aircraft carrier battle group, forming a combat system that can get out of the island chain.
