It's good and promising.

For example, the Star Wars project, whose function is anti-missile in space, destroys local intercontinental missiles in space.

Then, the nuclear bomb can be carried into space, and then hit the ground vertically from space, with higher accuracy and penetration ability than ballistic missiles. ?

If the land-based long-range bombing artillery wants to achieve long-range strike, according to the current technology, it is possible to use rail guns under the condition of ensuring shooting accuracy. For example:

The US Navy tested an electromagnetic gun with a range of more than 200 kilometers and a speed of Mach 7.5.

Secondly, at present, the longest range is China's large-caliber rocket launcher.

This is the latest generation of rocket launcher WS- 1B developed and produced in China, which is an improvement of the original rocket launcher with a range of 180 km. The rocket launcher has a caliber of 406 mm, a maximum range of 360 km and a killing radius of more than 450 meters. Experts pointed out that this is the largest caliber rocket launcher in China and the longest range rocket launcher in the world. ?

Guardian -2 rocket is 7150mm long and 400mm in diameter. Guardian -2D rocket is 8 100 mm long and 425 mm in diameter. In terms of range, the maximum range of Guardian -2 is 200 kilometers, while the maximum range of Guardian -2D is 400 kilometers. If you add a guidance system, it will be a short-range ballistic missile.
