The following is the Singapore Ministry of Transport March 8, 2017 report: Safety Investigation Into Collision Between Alnic MC and The USS John S McCain in Singapore Territorial Waters on 21 August 2017.

From the Report:

In the pre-dawn hours of 21 August 2017, the Liberian-registered Alnic MC and the US Naval vessel USS John S McCain collided in the westbound lane of the Singapore Strait, in Singapore territorial waters about 4.6 nautical miles (nm) from Horsburgh Lighthouse. The collision resulted in 10 fatalities on the USS John S McCain.

The safety investigation determined that the USS John S McCain made a sudden turn to Port (left) into the path of Alnic MC because of a series of missteps that took place after propulsion controls were transferred.

When the Bridge team of Alnic MC saw the USS John S McCain turning, it presumed that the USS John S McCain would be able to safely pass ahead. The collision happened within three minutes of the USS John S McCain turning to Port, and the actions taken by Alnic MC were insufficient to avoid the collision.
