Following a request for assistance from the Argentine government, the Portsmouth-based navy ship immediately changed course from her planned tasking and sailed to join the multi-national efforts to find the missing submarine ARA San Juan.

HMS Protector is the United Kingdom’s ice patrol ship, and as part of the scientific and oceanographic work she conducts is equipped with sonar equipment which can search beneath the waves.

The Commanding Officer of HMS Protector, Captain Angus Essenhigh, said: “Having arrived on station early this morning we are now assisting with the search and rescue efforts and my team on board are trained and equipped to deal with this task. They worked hard to ensure we were ready to begin search operations as soon as we arrived and we are now on task, using all the means at our disposal to try and locate the submarine. Our thoughts remain with the crew of the ARA San Juan and their families at this time.”
