USS Connecticut is one of US Navy's most capable attack submarines. The Sea Wolf Class submarines were conceptualised and built to take on complex Soviet submarines.
The latest incident evokes memories of the incident involving another US Navy submarine USS San Fransisco which rammed into a mountain at the depth of 500 feet. One crew member had lost his life in that mishap.
Since then, the US Navy has been constantly upgrading its SUBSAFE programme which involved rigorous assessment of design, manufacture and maintenance of the nuclear submarine fleet.
