'Black holes' for Vietnam
In recent years, Vietnam has acquired six Russian Kilo-class submarines. Two were delivered in 2017. The subs are nicknamed "black holes" by the US Navy, because they run very quietly and are difficult to locate. They are specialized for missions in shallow waters and for defense against enemy ships and submarines.

Sailing by the Paracel Islands — a summary
China, Taiwan and Vietnam all claim sovereignty over the Paracel Islands.
All three require either permission or notification before a military vessel or warship engages in "innocent passage" through the territorial sea.
But under international law, all ships — including warships — can pass through the sea without getting permission or giving advanced notice.
As China claims self-governing Taiwan as its own territory, it views the US Navy's presence in the area as a show of support for the island's democratic government.
