N. Korea's Mini-Sub Plated With Sonar-Absorbing Tiles to Evade Detection

Ryu Yong-won

N. Korea's Shark class and Yugo class mini-submarines are plated with sonar-absorbing tiles to evade detection by our side, and some Yugo class mini-subs carry 533mm heavy torpedoes, it has been revealed.

Intelligence sources said on Apr. 6 that, according to investigation by relevant authorities regarding N. Korea's (mini-)submarine, torpedoes and mines, N. Korea obtained Russian technology with which they developed sonar-absorbing tiles and plated their Yugo class mini-submarines with them. The tiles are made of chlorinated rubber with silicon mixed in. N. Korea is said to have had trouble developing adhesive which would glue tiles to mini-subs.

In addition to 85-ton model which was captured in '98 off the coast of Sokcho, Yugo class mini-submarine also features other models such as 60-ton and 50-ton varieties. Yugo 1 model, the smallest of them, is basically a human torpedo with one or two crew(s,) designed to mount suicide attack on ships such as a U.S. carrier. Yugo class mini-submarines can stay underwater for 4~5 hours, and due to (insufficient) battery capacity, cannot move at high speed. Semi-submersible vessel can navigate at 40 knot(84km per hour) on the surface, but the problem is that its Swedish engine makes loud noise.

Underwater munitions such as torpedoes and mines are made at 'Dae-an Electric Enterprise' under Kang-sun Steel located near Nampo, the sources said. N. Korea was able to develop 'bubble jet' mines in 90's, and have been working on development of indigenous 'bubble jet' torpedoes.

N. Korea imported acoustic torpedoes from Russia in 90's, which homes in on the propeller sound of a ship, and have been making improvement on it.

Guy walks into an auto salvage yard and says to the clerk behind the counter, “I want a rear view mirror for my Yugo.”

The clerk says, “That sounds like an even trade.”

How can you tell a North Korean minisub from a South Koren minisub?

The NK carries an extra rubber band for the propeller.

Could be, could be...

Whoever it was, I'm just glad they did, and hope that whoever sells 'em motors in the future sells 'em noisy ones!
