March into space! Trump said that he would form a ＂space force＂.

　　　　　　 CCTV News:Some people say that the contest in the military field in the 21st century is not limited to land, sea and air, and "space" will become the new main battlefield. As the only superpower in the world and a leader in space science and technology, the United States has always attached importance to maintaining its military superiority in space. In his speech at the Marine Corps Air Base in Milla, President Trump proposed that the United States should establish a "space force".

　　　　　　 However, Trump did not elaborate on the relevant ideas of the space force. The Pentagon has not yet responded to this. In fact, this is not the first time that the United States has proposed the establishment of a "space force."

　　　　　　 In July 2017, the US House of Representatives proposed the establishment of a new service in the FY 2018 National Defense Authorization Bill — — Space forces. The proposal envisages that the United States will set up an independent space force in the navy with reference to the Marine Corps model. Supporters believe that the establishment of an independent and space-focused military force will help the United States stay ahead in the space race. The opposing side believes that the idea of establishing a space force is not mature enough and needs more research. Later, the bill was not passed by the Senate.

　　　　　　 [Extended reading] The "space forces" of all countries in the world

　　　　　　 The "space force" is a Xinjiang force that relies on satellite information reconnaissance, guidance and navigation and space weapons to fight in outer space. It is a new field of military competition among countries in recent years. Then, from a global perspective, what are the big countries in the field of "space forces" at present?

　　　　　　 The American "space force" has a long history.

　　　　　　 The US military currently has five major services, namely the Navy, the Army, the Air Force, the Marine Corps and the Coast Guard. Although there is no independent space force, the North American Air Defense Command, established in 1950s, actually has such a function. At that time, this department was mainly responsible for satellite launch, tracking other countries’ satellites and early warning. Now it has gradually developed into a multi-functional department with reconnaissance and early warning, space attack and space mapping and support.
