Stinger manpads?
What use are Stingers on the Pacific ocean?

What use are 155mm howitzers? Are you planning to line up a battalion of M777 on a carrier deck? HIMARS GMLRS lack range for any likely use.

What you need are long range antiship and land attack missiles, Standard SAM, ABM systems, etc.
Possibly ATACMs to shoot at the Spratleys from Palawan (already deployed).

The only critical item relevant to the Pacific, in use in Ukraine, is Patriot.

Now you are starting another debate all together. Wow. Nobody said those weapons would stop a China invasion and you are ridiculous to go that direction. I trained Navy and Marine F/A-18 pilots for Naval warfare a few decades ago including the first use of Harpoons by Hornets. Our attack submarine fleet alone would decimate any Chinese Navy or amphibious operation, even though 35% of our attack subs are down for maintenance, overhaul, or refit. But who really knows or even wants to find out by projecting weakness like we are now as a nation.

The Pentagon has already put out its own warnings for needing those munitions in a protracted war over Taiwan. We are not the military power we were in the 1991 Gulf war. China has a sizable nayy now and almost double our fleet size. They have hypersonic missiles and I would not want to see us in a hot war as they would make a real mess of things.
