How can Snow Dragon 2, which cost hundreds of millions to build, help? Why does our country need to build domestically produced icebreakers?

First of all, we need to understand what an icebreaker is. An icebreaker is actually a service ship. As the name suggests, it breaks ice to ensure that ships can safely enter and exit frozen ports and anchorages. So, how do you break the ice? Icebreakers usually use two methods to break the ice. When the ice thickness is low, they mainly rely on the impact of the bow and the force of the propeller to split and break the ice. This is the "continuous" ice breaking method. But what happens when the ice is too thick? At this time, a different method is needed, namely the "impact" ice-breaking method. ?

In today’s world, many countries have icebreakers, but not many can reach the two poles. We all know that the icebreaking level, endurance, power system and other requirements of an icebreaker capable of going to the pole are extremely high. In the 2019 data, the countries with icebreakers capable of traveling to the Arctic are Russia, Canada, Switzerland, the United States and Germany. Why are so many countries flocking to the Arctic? Because wherever there are people, there is competition. Once there are interests, games are inevitable. The Arctic is rich in resources, and the capabilities of icebreakers are critical to opening new sea routes.

Besides, our country is a newbie in Arctic exploration. For a long time, our country has lacked experience in polar equipment construction. Not only because of the numerical disparity, but also because of the lack of nuclear-powered icebreakers. Our country's aircraft carrier adopts steam power mode, which requires a large amount of fuel and requires a lot of work to ensure fuel. If the aircraft carrier is equipped with nuclear power, some of the shortcomings of our country's aircraft carrier will be solved in terms of power and energy reserves. The results of nuclear power operation tests on large-tonnage icebreakers are much higher than those on submarines and warships. Simply put, it is to provide strong technical support for the future development of aircraft carrier nuclear power and learn from the experience of aircraft carrier nuclear power application. If you want to make a breakthrough in this field, you must not only have strong comprehensive national strength, but also speed up the process of "make-up lessons". ?

At the same time, the achievements of the Chinese scientific expedition team in polar research activities are also worthy of praise. Although our country started late, we are working hard to become a powerful country in polar exploration. The construction of the fifth Antarctic scientific research station and the addition of "Xuelong 2" also reflect the steady implementation of China's "Xuelong" major exploration project planned to be implemented in the new era, which will usher in the development of China's polar undertakings. In a new chapter, China's polar scientific research is ushering in a prosperous new era.
