Submarine escape, rescue, abandonment and survival (SMERAS).

SMERAS is an internationally organised 'capability' which will involve almost any nation that can provide some assistance to the National Authority (NA) - the nation that owns the submarine.

This will include assets, people and support to the Submarine Search and Rescue Authority (SSRA) - the command and control organisation that will direct operations from naval headquarters, and the on scene commander (OSC) - the senior naval representative at sea. A DISSUB incident will require the assembly of a wide number of assets, people and organisations to undertake a successful recovery operation.
