Some perspective:

China apparently hit a moving ship target in the South China Sea with a missile fired from Qinghai province, roughly 2300km away.

This would be the equivalent of the U.S. hitting a moving ship target off the tip of Florida with a missile fired from Kansas. https://twitter.com/AndrewSErickson/status/1349546966661828610

The target was apparently hit near-simultaneously with a 2nd missile fired from just over 1500km away in Zhejiang Province.

This would be roughly like hitting that same target off of Florida near-simultaneously with a missile fired from Delaware. https://twitter.com/AndrewSErickson/status/1349547409177767936
