Confusion about steering control on the US naval vessel John S McCain has been blamed for a fatal collision with a Stealth Maritime tanker off Singapore last year.
The warship collided with the 50,800-dwt MR Alnic MC (built 2008) near Horsburgh Lighthouse on 21 August, killing 10 US sailors.
An investigation by Singapore's Transport Safety Investigation Bureau (TSIB) found that John S McCain made a sudden turn to port into the path of the tanker because of a series of missteps that took place after propulsion controls were transferred.
