As a stealth ship, why are the shapes of 055 and DDG 1000 so different?

The Type 055 destroyer independently developed by China and the DDG 1000 of the United States are stealth ships. What's the difference between them? Stealth here is not stealth in the ordinary sense. Anything that can't be detected by radar belongs to stealth ships. The side of a traditional ship is generally perpendicular to the sea level. When the radar wave strikes the side of the ship, the incident angle is basically 90 degrees, and the reflected wave will be very strong and easy to be found. So, in order to achieve the stealth effect of surface ships, take? Change the shape design of the ship? And then what? Using radar absorbing materials? Two methods, so as to achieve the effect of stealth. ?

The biggest difference is the difference in appearance. The front of DGG 1000 destroyer adopts wave-penetrating structure, which meets the requirements of high-speed navigation and stealth performance, and has no coupling effect on radar waves. The freeboard of China 055 is designed very low, almost reaching the limit of surface ships, which is also to reduce the coupling effect between radar waves and sea level, which is also the most essential difference between them. The great difference in design appearance means that their task focuses are different. The two different design concepts also reflect the different operational strategies of our two countries. Secondly, the DGG 1000 destroyer pursues the most ideal stealth effect, while the design of the 055 destroyer pays more attention to tradition and stability.

The unique shape of destroyer 055 also shoulders important tasks, mainly focusing on high-end and high-intensity operations such as air defense, anti-missile, anti-submarine and anti-ship. Can China's naval carrier battle group and surface ship battle group be more reliable? Air umbrella? Provide better protection for its offshore mission. The main feature of DDG 1000 ship is the joint fire support, which enables the ship to carry out accurate strikes and all-round fire strikes on shore targets under all-weather conditions. So these two stealth ships still have their own advantages.
