Submarine Escape
and Rescue
Liaison Office

The International Submarine Escape and Rescue Liaison Office (ISMERLO) is an organisation that aims to facilitate an international response for a distressed submarine (DISSUB) and to improve the ability to respond to a call for assistance through its coordination role. Although established by NATO, ISMERLO supports all nations and pursues the involvement of global submarine-operating nations. ISMERLO is a military organisation operating in an international environment focused on the humanitarian objective of saving lives at sea.



The Royal Canadian Navy SUBMED course

SUBMED 23 has ended after being fantastically hosted and run by the RCN.

Two weeks consisting of lectures and embarkation onboard the HMCS HARRY DEWOLF

It is the generosity of people taking time out of their very busy schedules that is most remarkable. Invaluable practical training was achieved and a brilliant road test of new features on ismerlo.org for DISSUB medical teams.



The 2023 meeting of the Submarine Escape and Rescue Working Group (SMERWG) took place at the Marina Militare Istitutio Di Studia Militari Maritimi, in Venice, Italy, 27 through 30 June 2023. A total of 130 delegates from 20 nations attended. A number of SMER related topics were covered in depth and it was a great opportunity to share and enhance knowledge across the global SMER network as well as maintaining and extending friendships. We are truly grateful to the Italian Navy who did an outstanding job in hosting the event in the historic and marvelous city of Venice.

CRF course 2023

NATO Coordinator Rescue Forces Course 2023

And so ends the Fourth NATO Coordinator Rescue Forces in Taranto, at the Submarine Flotilla Command.
We were honoured by the start of the course being officially given by the Commander of Submarines of NATO (COMSUBNATO), Rear Admiral Thomas Wall, and by the Commander of Submarines of the Navy (MARICOSOM), Rear Admiral Vito Lacerenza. 
This important two weeks in the SMER global calendar has again given a multinational, multi disciplined group of students the chance to gain knowledge of global SMER, taught by an international group of specialists, and experience practical live training scenarios to further their skills.
The course continues to grow and important work has been done by the students in establishing new ideas in how the CRF does their work during a DISSUB event, including live interactions with a major rescue asset, NSRS.
Looking to the future the course will continue to grow and improve - preliminary work has already been completed during this course in conjunction with the Italian Navy and we hope to link submarine controllers onto the course next year to achieve mutual training objectives.
