A NATO task force flagship and a frigate that departed Dublin Port after a naval visit to the capital at the weekend were designed to “strengthen maritime cooperation” with Ireland.

The three-day visit to the capital, as Afloat reported, involved the Dutch Navy’s amphibious vessel, HNLMS Johan de Witt (NATO flagship), and a German Navy frigate, FGS Hamburg. Both vessels had arrived on Friday and then departed on Monday this week.

It comprised “manoeuvring and communication drills” with the Irish Naval Service, as well as formal courtesy visits and receptions.

According to NATO, the sea drills demonstrated the “high level of co-operation and interoperability” between member states and partner countries, such as Ireland.

More than a quarter century ago, Ireland joined the NATO Partnership for Peace (PfP) in December 1999, a voluntary arrangement between “partner” countries and NATO.

More reports from the Irish Examiner, including a comment from former Defence Forces Chief of Staff, Vice Admiral (Rtd) Mark Mellett, on the NATO visit.

Naval Visits focuses on forthcoming courtesy visits by foreign navies from our nearest neighbours, to navies from European Union and perhaps even those navies from far-flung distant shores.

In covering these Naval Visits, the range of nationality arising from these vessels can also be broad in terms of the variety of ships docking in our ports.

The list of naval ship types is long and they perform many tasks. These naval ships can include coastal patrol vessels, mine-sweepers, mine-hunters, frigates, destroyers, amphibious dock-landing vessels, helicopter-carriers, submarine support ships and the rarer sighting of submarines.

When Naval Visits are made, it is those that are open to the public to come on board, provide an excellent opportunity to demonstrate up close and personal, what these look like and what they can do and a chance to discuss with the crew.

It can make even more interesting for visitors when a flotilla arrives, particularly comprising an international fleet, adding to the sense of curiosity and adding a greater mix to the type of vessels boarded.

All of this makes Naval Visits a fascinating and intriguing insight into the role of navies from abroad, as they spend time in our ports, mostly for a weekend-long call, having completed exercises at sea.

These naval exercises can involve joint co-operation between other naval fleets off Ireland, in the approaches of the Atlantic, and way offshore of the coasts of western European countries.

In certain circumstances, Naval Visits involve vessels which are making repositioning voyages over long distances between continents, having completed a tour of duty in zones of conflict.

Joint naval fleet exercises bring an increased integration of navies within Europe and beyond. These exercises improve greater co-operation at EU level but also internationally, not just on a political front, but these exercises enable shared training skills in carrying out naval skills and also knowledge.

Naval Visits are also reciprocal, in that the Irish Naval Service, has over the decades, visited major gatherings overseas, while also carrying out specific operations on many fronts.

Ireland can, therefore, be represented through these ships that also act as floating ambassadorial platforms, supporting our national interests.

These interests are not exclusively political in terms of foreign policy, through humanitarian commitments, but are also to assist existing trade and tourism links and also develop further.

Equally important is our relationship with the Irish diaspora, and to share this sense of identity with the rest of the World.
