“The Outer Space Treaty represents the basic legal framework of international space law. Among its principles, it bars states party to the treaty from placing weapons of mass destruction in Earth orbit, installing them on the Moon or any other celestial body, or otherwise stationing them in outer space. It exclusively limits the use of the Moon and other celestial bodies to peaceful purposes and expressly prohibits their use for testing weapons of any kind, conducting military maneuvers, or establishing military bases, installations, and fortifications (Article IV). However, the Treaty does not prohibit the placement of conventional weapons in orbit and thus some highly destructive attack strategies such as kinetic bombardment are still potentially allowable. The treaty also states that the exploration of outer space shall be done to benefit all countries and that space shall be free for exploration and use by all the States.
The treaty explicitly forbids any government to claim a celestial resource such as the Moon or a planet. Article II of the Treaty states that "outer space, including the Moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means". However, the State that launches a space object retains jurisdiction and control over that object. The State is also liable for damages caused by their space object.”
My opinion is that this is just a strategy to make Russia and China think the US has had some major technological breakthroughs, which will force China and Russia to spend shit loads of money trying to catch up. A similar strategy Reagan used with the “Star Wars missle defense system.” Even though that was touted in the 1980’s, we are only now seeing advancements in laser and railgun military weaponry.
