The US National Transportation Safety Board has blamed the 2017 collision between a Navy destroyer and a Stealth Maritime tanker on a lack of oversight and training, while mostly exonerating the tanker's crew.
On 21 August, 2017, the USS John S McCain lost steering in the Singapore Strait, colliding with the 50,800-dwt Alnic MC (built 2008), killing 10 servicemen and injuring 48 others.
