What is the point?
You have to use:
1. a bigger and more expensive radar
2. a bigger VLS system with a smaller number of cells
3. a much larger SAM which costs way more than the incoming anti-ship missiles
Yet what targets will these missiles realistically be able to hit at 200km+?
400-500km SAMs make sense when you have high-flying targets (within the radar horizon) and are within 400km. The only targets that qualify are AWACS and surveillance aircraft which are forced to, because they are defending a land mass.
It's worth it!
Alot of air launched anti ship missile has greater than 200km range.
