The western missile test range includes Point Mugu (Navy) and Vandenberg AFB (USAF). Launches from both easily can be seen in southern kalifornia and under special circumstances like Saturday night, by a large part of the southwestern US.
Indeed, that is our testing range, and has been since the 50’s. Some will remember that the floating platform with the anti-ballistic missile (”Star Wars”) launch gantries on it, was stationed out of / in the sea near Kwajalein Atoll in the Marshalls. This was the testing the lefties and the soviets stooges in our press derisively called “Star Wars”. And, it worked, as did the defenses set up in the Arctic Circle of ABM launchers.
Please people, get a grip. The LA Times indicates that every missile boat, after it goes through re-fueling (which occurs btw after up to 25 years from original reactor startup and is good for another 25 years!!) it then has a shakedown cruise for systems performance, reactor, all systems and... weapons (includes torpedoes and cruise missiles). If they can tie this test to another one— they are saving money. Some idiots said it exploded and put up a video that shows an airliner— way the hell out of the NOTAM zone... appearing to be an ABM... good Lord, how stupid.
