Germany has a reputation for building technologically sophisticated submarines. The West German "Klasse 740/03" Narwal Dry Combat Submersible (German Unterwassertransportgerät, UWTG) was built and operated in secret in the final days of the Cold War.

Very Slender Vessel (VSV) 
It is a myth that North Korean naval vessels are by definition clones of older Russia or Chinese designs. In fact North Korean naval architects have produced a long string of original designs, often with novel features.

North Koreas next Ballistic Missile Sub
Making predictions is a fool’s business. Naval developments are constantly evolving and one year’s hot topic is the next year’s forgotten fad. Not to mention that naval architects are forever coming up with ingenious and unpredictable ways to achieve the same aim. North Korea’s recent successful submarine launched ballistic missile test and fifth nuclear test raise the question of how they will operationalize their submarine based capability. It is a question which has cropped up in a few places and is very interesting, so like a fool, here is my prediction... Read More >....
