The number of missiles carried on board does not match the displacement of the ship. This might indicate higher survivability; The ship might not get one-shotted by a hypersonic missile. It will also be much tougher against other threats such as subsonic stealth cruise missiles and water drones. Keep in mind, bigger ships are harder to sink, especially if they're not crammed to the brim with ammunition and other systems. And with the increased survivability requirements of the US navy (which caused the constellation disaster in the first place), I believe this new Trump class will be deserving of the classification of Battleship RELATIVE to other modern warships.
PLA doesn't care for actually physically sinking the ship.
Mission kill is what it will be aiming.
For such an expensive, low quantity, and critical node ship of the US, it will surely receive a premium package of hypersonic missiles
Any such missile hitting, and it is probably a near 100% certainty that it will get mission killed.
So I don't think the survivability argument is valid here
Another important thing that was mentionned by Phelan in the press release is that this will be a "command" ship, which could indicate that it might operate in coordination with other manned and unmanned surface vessels, serving as a central "node", kinda like a ship equivalent of an AWACS.
But having such an expensive and limited numbers ship, it actually goes against the distributed lethality concept that the US has been following. If they concentrate all these functions into one big node, it will only help China by introducing such a big target that if mission killed would affect the entire battle ground
To be fair, I am not that against the entire concept. Something close to it is what I envision the next type 055 iteration to be, but that would only work for China as you can trust it's MIC to pump it out in reasonable numbers, good build speed, and relative cheap price.
If US has to spend almost a 10 billion dollars for a single ship and take god knows how many years to build it, it would be built in minimal numbers and China could easily take them out if specifically targeted. And once out of action, congrats, your Asia Pacific theater out of the blue now has a big hole
For US national conditions, cheaper, distributed lethality platforms is imo the way to go. Really bizarre seeing them go the opposite way now
