@izzythepush,
I dont think a war with China or Russia will be "conventional"> It may start out as such but the losing side would "go nuke" rather quickly.
North Korea has 70 ubmarins, most of them Romeo class (ith screen doors and gas turbines) from the 50's.
Russia and China together hqve bout 135 and the US has 85 (with a huge advantqge in Nuke missile subs). Russias fleet is mostly rusted out and China is the coming leader of the S China Sea. (Japan and Taiwan and India can hold them off but I think wed be sucked in by SEATO treaties).
The ppresent rquest is to build 66 MORE nuke subs. and a huge surface (Target navy). Surface vessels are getting outdated , even carriers couldn't last long with attack sub packs firing ballistic missiles(not cruise) from 500 miles away.
Remember, you hear limited capability reports from Russia Chin and Iran. You dont hear it all and you generally hear NOTHING about what weve got in the pipeline. NOBODY knew about stealth helicopters till we killed bin Laden. We may already have MIRV satellites in orbit and Im mostly scared qt giving some impulsive douche bag like Trump, the "fooball"
Speculation is mine
