html Starting from October 8, the first 600-ton cathode wave-through patrol ship , the newly built shore, "Anping" ship (CG601), began to go to sea for trial sailing. The Anping ship was launched at the CITIC Shipbuilding Gaoding Shipyard on April 27. After completing the outfit, it underwent two factory trials on September 15 and September 28, and is expected to be delivered to the Coast Guard Administration in mid-November.

This type of ship can be seen at a glance. It is a simplified version of the Tuojiang-class patrol ship . It has made certain improvements to the work nature and usage needs of the Coast Guard Administration, enhance the strength and stability of the hull structure, add high-pressure water cannons, and remove ship-based weapons, but reserves interfaces for various weapons, highlighting the concept of "combining peace and war".

Regarding catamaran wave-passing ship, military fans have always had a complex emotion, because the 22 missile boats built in large numbers in China also use catamaran wave-passing structure. In the late 1990s, the magazine " Ship Knowledge " introduced Australia's "Wave Cat" catwalk through waves in detail. This technology was introduced by the US Navy and built a high-speed transport ship. The country also used this technology to build a Type 22 stealth missile boat.

However, it came and went quickly, and the 22 missile boat was short-lived and soon disappeared from the sight of military fans. Later, everyone learned that the catamaran wave missile boat has many advantages, but its disadvantages are also obvious. First of all, the hull is an aluminum alloy, which is often corroded in sea water. If you don’t go out to sea for a period of time, you have to board the boat. Secondly, the two-body structure prevents the hull from being too large. The 22 type has a displacement of only more than 200 tons, a short range, a small living space for crew members, poor self-sustaining power, and unable to perform maritime tasks for a long time. Third, after the anti-ship missile was launched, the rear of the hull was lightened, and the center of gravity changed to "bury the bow". Fourth, the catamaran is poorly navigable under high sea conditions. Some sailors once discovered that mice on the 22 boats were incapable of moving due to seasickness.

Because there are many problems with the catamaran wave ship, the Type 22 missile boat was quickly replaced by the 056 frigate . However, the other shore still attaches great importance to this catamaran surfing ship, and started construction of a "causa missile ship with an occult function" in November 2011.

On March 14, 2014, the first ship of the Tuojiang-class light missile patrol ship (618) was launched and was named "aircraft carrier killer", which immediately sparked heated discussion among netizens. This reminds us of the scene when the 22 boat was born. In the thirty years of Hedong and thirty years of Hexi, we never expected that the other side would carry the banner of "aircraft carrier killer".

Tujiang-class ship is 60.4 meters long and 14 meters wide. It has a full load displacement of about 550 tons. It uses two 15,000KW diesel engines and water jet propulsion systems as power. The catamaran wave-through structure can effectively reduce drag. It is conservatively estimated that the maximum speed is about 38 knots, which is not fast for the catamaran. It is also a considerable pressure to carry 16 anti-ship missiles on the ship.

It is estimated that the 22 missile boat has poor self-sustainability and poor airworthiness also exists at the Tuojiang class. We are not nervous about the Xiongfeng 2 and Xiongfeng 3 anti-ship missiles on the ship, and our range and power are not as good as the Eagle Strike missile. Moreover, the Type 22 must rely on our reconnaissance system and data link to achieve its effect. There is no complete combat system on the other side, so the power of the Xiongfeng missile is very limited.

Its root cause, the other side is currently the same as we did back then. We have no money or technology, and want to defeat the enemy and win. We can only think of bad ideas such as "asymmetric combat" and "sea guerrilla warfare". Although there is no hope of winning at all, it is also good to be able to hold on for one more day, and you can get as much precious time as possible. Our army also proved that this idea almost didn't work in later exercises, but that was almost the only way at that time.

Now, the Tuojiang class has been changed to a patrol ship. In addition to the Anping ship launched, there are three more ships under construction. According to the concept, the mission scope of the 600-ton two-cylinder patrol ship needs to cover the Diaoyu Islands, the economic seas overlapping with the Philippines on the other side, as well as the Dongsha , Nansha seas, etc., and its endurance cannot be less than 5,000 nautical miles. It is probably difficult. The catamaran is so useful, why do we have to work hard to build a 10,000-ton coast guard ship?
