The warship was currently sailing under its own power and heading to port, the Navy said. The Alnic MC is a Liberian-flagged, 183 metre-long oil or chemical tanker of 50,760 deadweight tonnes, according to shipping data in Thomson Reuters Eikon. Shipping data showed it last sent a transponder signal at 2258 on GMT Sunday and has since come to a halt 10-20km off the east coast of the Pengerang peninsula in Johor, southern Malaysia. The ship data showed it was "ballasting", meaning that it was not loaded full of oil for cargo. The waterways around Singapore are some of the busiest and most important in the world, carrying around a quarter of the world's trade in goods and oil.FYI, it's named after the OTHER John S. McCain folks, as in WWII...so don't even get started. #USSJohnSMcCain #USNavy

#USSJohnSMcCain #USNavy another naval collision. How can this happen with GPS and AIS??? https://t.co/osY7oBLuM4— Dr. Malcolm Davis (@Dr_M_Davis) August 21, 2017North Korea threatened last week to fire ballistic missiles toward the US Pacific territory of Guam, ratcheting up tensions with US President Donald Trump, who had threatened to unleash "fire and fury" on Pyongyang if it threatened the United States. The US Navy vessel involved in the latest collision is named for the father and grandfather of US Republican Senator John McCain, who were both admirals in the United States Navy. "Cindy & I are keeping America's sailors aboard the USS John S McCain in our prayers tonight - appreciate the work of search & rescue crews," McCain said on Twitter. Senator McCain is a Vietnam War-era naval aviator who was shot down and held prisoner for five-and-a-half years. He is now undergoing treatment for brain cancer.
