I’ve often wondered what the 1st string targets would be for NK’s submarines.
Off the top of my head, the following US bases would probably be very important in the event of a renewed Korean War:
Okinawa (would undoubtedly be a front-line base);
Diego Garcia (one of only 2 bases where B2 bombers are stationed, and probably much more useful than the one in Nebraska);
Guam (likely an important supply waypoint for US military).
Oahu, Hawaii (same as Guam).
NorKo literally can’t get its ships from one side of the peninsula to the other. Which would not stop them from trying to sink essentially terror targets - cruise ships, large cargo vessels (especially LNG or CC) or even large yachts.
500 guys with black powder pistols could create quite a bit of havoc in a US city. That NorKo is a paranoid nation with 1950s weaponry doesn’t mean they couldn’t create quite a mess, with no good way to respond as long as China doesn’t approve world actions.
AFAWK, the NK sub fleet is entirely diesel electric, which, while having certain advantages (extremely quiet submerged/running on electric), faces the same disadvantages of Nazi Germany’s U-Boat Fleet in the Atlantic after spring, 1943.
Sooner or later, they have to surface and run their diesels to recharge, and to replenish their air supply.
And compared to nuclear subs (who also have to surface sooner or later, or their crew starves to death), a D/E sub’s “surface requirement” is much, much “sooner.”
At which point, they’re dead meat against any modern surface combatant, or aircraft-born anti-ship missile(s).
As noted above, that doesn’t mean that they can’t wreak bloody havoc with unarmed merchants and such; it is conceivably possible that, with enough cunning and patience (not to mention a dash of luck), they could knock off a modern surface combatant as well.
I did read that article.
I can assure you the US is sophisticated enough to hear more underwater than you might believe. Go find a copy of “Blind Man’s Bluff” and read it.
Thankfully the people who are charged with defending the US and South Korea do not display such ignorance. Those people are aware of a little country called the People’s Republic of China. That country would not sit idly by while your suggestion is carried out.
Wait a minute – is this saying that about 50 subs just vanished, as in, sank or otherwise mysteriously disappeared (e.g., due to the general decrepitude of all things North Korean)?
Or is this saying that those 50 subs left their home ports and are now on patrol, who knows where? and with what (possibly nefarious) mission?
Why are South Korea and US searching for them? Does this mean we think the second scenario is the case (that they are out on some secretive, and probably malign, mission)?
