US reveals details of nuclear submarine collision with underwater mountain

A US Navy nuclear submarine that was severely damaged in an accident while submerged in the South China Sea last month struck an uncharted underwater seamount, the US Navy said Monday, South China Morning Post writes.

The US 7th Fleet, which operates in the western Pacific, said an investigation had concluded that the USS Connecticut smashed into a geological formation and not another vessel on October 2.

“The investigation determined USS Connecticut grounded on an uncharted seamount while operating in international waters in the Indo-Pacific region,” a 7th Fleet spokesperson said in an emailed statement.
