To sum it up: There are an unknown number of North Korean subs that vanished but it is at least 50 that can't be located. Most of them were new. At least 40 were between 160 and 250 feet in length, some can submerge to 1000 feet, and at least a significant number of them can engage targets 100 miles away due to the fact that they have good updated electronics. This is confirmed fact. North Korea has a good submarine manufacturing program. The best one missing is 350 feet long and might be able to make it to the west coast. It can launch nuclear missiles with a range of 850 miles while submerged, and is a massively upgraded cold war design from Russia that was built new in 2014 and actually ended up being an excellent sub. Other than that, little is known about it, but the Russians considered North Korea's accomplishment with this sub to be an impossible achievement, and aknowledged that after an extensive 20 year study of 10 subs North Korea bought from Russia as totally inoperable scrap North Korea successfully improved the design and built an extensively upgraded and perfectly working model.
The new updated North Korean sub is based on a Russian design that last saw service in 1990, and since it is massively upgraded from that it can probably be considered first world modern. I was very surprised to find that out.
A minimum of 40 missing subs have a western rated duration of 60 days or more, which North Korea could probably push to 5 months if they packed extra food, stayed in position, and only surfaced to re-charge the batteries.
This may be what got the report deleted: The U.S. cannot detect these subs from more than 5 miles away if they are not in motion and parked on the ocean floor. North Korea's main problem is propeller design, their propellers are not quiet enough, but their subs are quiet enough if they are not moving and are parked on the ocean floor which makes sonar location difficult. Since the area around Korea is only a few hundred feet deep, these subs can reach the bottom and end up being a real problem.
The Nork subs are quieter than nuclear subs when parked on the ocean floor because nuclear subs make clicking noises in the reactors, and diesel electric subs use batteries while submerged which are completely silent. So North Korea has a real submarine deterrent. All but 10 of the missing subs can launch nuclear torpedoes if the Norks have nukes to put in them.
North Korea's least capable subs are 10 midget class subs that can still, due to greatly upgraded electronics, engage targets successfully from 60 miles away
