Well said, B PLT. And to BBTW, I am of an "Air Force bent", but I fully support maritime-based air power, defence of the fleet and projection. I suspect a lot of people here do. Remember that most posts are short (thankfully) because posters address a particular point, not a complete discourse of everything they think.
I spent the first 5 years of my AD career doing defence of the fleet, but that required a land base. The new capital ship (which is what it will be) requires a fully layered AD system. T45, etc will be a part of that, but not all.
