The USS Michigan guided-missile submarine arrived in South Korea for what a US defense official described as a show of force amid tensions between the US and North Korea.

The USS Michigan – capable of firing off salvos of Tomahawk cruise missiles – is to join the aircraft carrier USS Carl Vinson in drills near the Korean Peninsula.

That was reported by www.thesun.co.uk.

The sub belongs to the Ohio class of boats which are the biggest of their kind ever to be built for the US Navy.

North Korea celebrates its army’s 85th founding anniversary today and reports suggest it has marked the event with its “largest ever firing drill”.

It is feared the anniversary will be marked with the testing of a nuclear device or a ballistic missile.
