North’s submarine may fire missiles: U.S. group

Recent satellite imagery appears to show that a North Korean submarine is being equipped to fire missiles, posing a potential new threat to its neighbors, a U.S. research institute said Thursday.

The finding published by 38 North, the website of the U.S.-Korea Institute at the Johns Hopkins School of Advanced International Studies, comes as Washington ratchets up sanctions against North Korea following a destructive hacking attack against Sony Pictures.

North Korea already has a considerable arsenal of land-based ballistic missiles. South Korea’s Defense Ministry reported this week that the North may now have the ability to strike the U.S. mainland because of its progress in missile technology - although how far it has progressed remains subject of debate.

The ministry also said the North is advancing its efforts to miniaturize nuclear warheads to mount on such missiles.

Missiles fired from submarines could be harder to detect before launch than land-based ones, and North Korea’s efforts have already gotten the attention of defense officials. South Korea’s military said last fall that it had detected a North Korean submarine with a possible capability to launch ballistic missiles.

The institute has previously reported that North Korea was building a missile-testing facility on land near a naval shipyard at the east coast site of Sinpo.
