North Korean submarine that went missing is believed to have sunk, new reports claim
The North Korean submarine which has gone missing is now presumed to be sunk at sea.
This vessel was reported to have been patrolling the communist country's coastline when it went missing.
An unidentified US government source has told USNI News: "The speculation is that it sank.
"The North Koreans have not made an attempt to indicate there is something wrong or that they require help or some type of assistance."
North Korea has a fleet of 70 submarines, most of which are diesel-powered vessels.
They range in size from midget craft that carry only a handful of sailors to larger ones with up to 40 crew.
These ageing submarines are thought to be only good for coastal defence and limited offensive actions, reports the Guardian.
North Korean analyst, Joe Bermudez said: "They have many problems with maintenance – levels of maintenance standards are lower than most comparable navies in East Asia."
Despite these reported failings, one of these vessels allegedly sunk a South Korean corvette with a torpedo strike in 2015.
