The Submarine Escape and Rescue Working Group (SMERWG) is the authority for ISMERLO.  All submarine operating nations are strongly recommended to attend.  SMERWG covers technical and procedural issues concerning all aspects of the subject with the aim of sharing information and establishing mutually accepted standards for design and operation of SMER systems.  This is also a forum wherein problems are briefed, exercises and their lessons learned discussed, and invitations to attend or observe those exercises are made.  It is a gathering of the principal experts in this field and is an opportunity to establish contact with them that is unmatched.

One of the important issues to arise after the KURSK tragedy, underlined by other peacetime submarine disasters, was the need for an international liaison service to coordinate rescue efforts in case of further submarine disasters and make those accidents less likely to occur.  This has evolved into the concept of the International Submarine Escape and Rescue Liaison Office (ISMERLO).   This office will consist of an international team of submarine escape and rescue experts based at Norfolk Virginia in the USA.  The aim of ISMERLO is to establish endorsed procedures as the international standard for submarine escape and rescue using consultation and consensus amongst submarine operating nations.  Advice on training and procurement as well as an inspection and monitoring service are also tasks assumed by this organization.

All nations are invited to forward details of their SMER facilities and capabilities for inclusion on the ISMERLO website.  Please note that all contributions, however minor, will be of use and may well generate requests to participate in future exercises.   Forward details for inclusion to
