Doesn’t the Tomahawk have a cluster munition warhead?
I imagine an Ohio SSGN conversion or two, plus a few SSNs with a bunch of those would really mess with any attempted invasion. Especially if you get Ticonderogas and Burkes launching them from a completely different direction.
People tend to forget that in a war with China the one thing that the USN isn’t going to do is raise battle flags and steam it’s carriers into the Taiwan Strait. The carriers will kept to the East and be used to provide defense air cover for the other subs and ships that will go after the ChiComs. And probably be used to conduct offensive fighter sweeps over Taiwan as well.
SSGNs would only be of value hitting the staging areas. Historical ROE would dictate that we aren’t going to do any shooting until they leave the staging areas.
No, precision weapons flying to a designated lat/long aren’t of much use on moving targets.
Attack helicopters would be the best platform to use against landing craft, once the screening DDGs and air cover were taken out of the fight.
