Just some thoughts ...
What missiles do you have in mind?
US Navy has several versions of the Raytheon “Standard” missile. I suspect those would do the job very nicely ... over open water. They’re launched from our destroyers and cruisers. None of them are available in the Arctic Ocean in winter. Or even in summer.
The Patriot air defense system has a max altitude around 80,000 ft ... but it’s a short range system designed for point defense. I doubt we have any operational in northern Alaska ...
THAAD reaches up to 90(?) miles and is a more regional air defense system, but I don’t think we have any deployed operationally within the United States.
The Ground Based Interceptor system in Fort Greely is specifically designed to counter ICBMs.
And that’s why we have fighters and their RADAR and IR guided missiles. They’re just much more flexible and adaptable than ground missile systems.
Thank you - that makes a lot of sense....Appreciate it.
