Thank you for taking the time to create the scenario. That was very nice of you to do.
I've played your scenario, and many like it, probably 500 times. I usually use the C and E versions of the SM-3.
Did you notice that the TPY-2 took a while to SEE the incoming missiles even though they were only 340 miles (or less) away. The range of the TPY-2 is 540, and it reportedly can "see a baseball being hit out of the park from several hundred miles away." Those missiles are many times larger than a baseball, yet the TPY-2 has trouble finding anything until the target gets within 340 miles (as I said). I would think that they would see them earlier, and at a greater distance than 340 miles.
On the ship end, I've had similar results. But, your scenario was set up under pristine conditions. Had you given the ship a 45 degree heading, instead of 0, the ships would have had to turn. Turning eats up precious time, it cuts into the launch window, and keeps them from being able to get off any shots even longer.
Notice, also, that the ship was only able to get off 7 of the intended 8 missiles BEFORE it could no longer fire because it wasn't able to. It would be much less if they had to turn. And, as I said, there wouldn't be any at all if it adhered to the 330k foot deck.
Also, when the hips begin firing, the DF-21s have already descended to 70 km (or 230k feet). According to the game, the deck for SM-3 is 330k feet, so it is already below the deck, and it should no longer be able to fire at them at all because they are too low.
Additionally, your TPY-2 is strategically placed in between the the target and the shooter. In real life, had the group been sailing into the SCS, any land-based radar would not be so conveniently placed. Units could be placed in Brunei , Malaysia, or the Philippines and they would be (as I said) at least 200 miles further back from the ships, and the land-based radar wouldn't be detecting them any quicker than the ships do.
Your scenario yields similar results, but degrading the situation just a little (heading/TPY-2 positioning) and it will severely alter the results.
Thanks again for making the scenario for me.
This is the point, Doug. If you have other assets in other places that can see the missiles it gives you a better shot. The one I placed in Taiwan isn't unreasonable.
In terms of accurately placing them as thewood mentioned ABM radars are in lots of places and US and Japanese ships with BMD radars could be in lots of other places. Those places are chosen on the basis of giving ABM a good chance of working minus a few territorial things If they're not in your scenario or in the right place by chance, thems the breaks.
I'd pursue your DB change though. I think that's reasonable.
