#RussianSubs - Russian submarines have been tracked through the Irish Sea by the British military in recent days, according to Mail Online.

Two nuclear-powered Akula-class submarines were reportedly monitored by Royal Navy radar as they travelled to meet with a third sub tracked by Norway towards the English channel.

It’s understood all three were tracked by a Royal Navy sub before they went deep.

The situation comes after Russia unveiled a new stealth submersible craft amid escalating tensions over Russian President Vladimir Putin’s interventions in Syria.

#Trident - Trident won't be coming to Northern Ireland - as there are no waters deep enough to host the nuclear deterrent submarines, according to one MLA.

As the Belfast Telegraph reports, Ulster Unionist MLA Steve Aiken says that from his own experience, the region has no suitable deepwater ports or inlets necessary for the 150m-long Vanguard-class submarines in the Trident programme, which are currently stationed off western Scotland.

"It's not deep enough, we can't do it," he said. "I tried to bring my submarine, HMS Sovereign, to Belfast towards the end of its time.

"Because you need deep water at all states of the tide, even though entrance to Belfast Lough is dredged to 10 metres, it's not deep enough.

"You can't bring it into Larne because there is a rock sill coming into Larne Lough which you would have to blast out; same for Carlingford Lough, and Lough Foyle is too shallow."

#Hydrophones - Could the world's network of hydrophones used by marine scientists to track ocean sounds such as whale songs also be used to spy on the movements of military submarines?

That's a real concern among North America's top brass, as Matthew Braga writes in The Atlantic, for the instruments used by scientists to collect important data on marine wildlife send their information openly across the internet – and may be transmitting more than they think.

"There's a long tradition of the ocean being the exclusive domain of the militaries and the fishing community, and we're more or less interlopers in this world," says Canadian microbiologist Kim Juniper, who explains how some of the data collected by Ocean Networks Canada is diverted – often on a whim – to a secure military computer to parse for potentially classified information.

It's an inconvenience for scientists in the field, to say the least. But since their hydrophones hear everything that passes by - both natural and man-made - the potential security threat is very real.

Ireland's Trading Ketch Ilen

The Ilen is the last of Ireland’s traditional wooden sailing ships.

Designed by Limerick man Conor O’Brien and built in Baltimore in 1926, she was delivered by Munster men to the Falkland Islands where she served valiantly for seventy years, enduring and enjoying the Roaring Forties, the Furious Fifties, and Screaming Sixties.

Returned now to Ireland and given a new breath of life, Ilen may be described as the last of Ireland’s timber-built ocean-going sailing ships, yet at a mere 56ft, it is capable of visiting most of the small harbours of Ireland.

Wooden Sailing Ship Ilen FAQs

The Ilen is the last of Ireland’s traditional wooden sailing ships.

The Ilen was designed by Conor O’Brien, the first Irish man to circumnavigate the world.

Ilen is named for the West Cork River which flows to the sea at Baltimore, her home port.

The Ilen was built by Baltimore Sea Fisheries School, West Cork in 1926. Tom Moynihan was foreman.

Ilen's wood construction is of oak ribs and planks of larch.

As-built initially, she is 56 feet in length overall with a beam of 14 feet and a displacement of 45 tonnes.

Conor O’Brien set sail in August 1926 with two Cadogan cousins from Cape Clear in West Cork, arriving at Port Stanley in January 1927 and handed it over to the new owners.

The Ilen was delivered to the Falkland Islands Company, in exchange for £1,500.

Ilen served for over 70 years as a cargo ship and a ferry in the Falkland Islands, enduring and enjoying the Roaring Forties, the Furious Fifties, and Screaming Sixties. She stayed in service until the early 1990s.

Limerick sailor Gary McMahon and his team located Ilen. MacMahon started looking for her in 1996 and went out to the Falklands and struck a deal with the owner to bring her back to Ireland.

After a lifetime of hard work in the Falklands, Ilen required a ground-up rebuild.

A Russian cargo ship transported her back on a 12,000-mile trip from the Southern Oceans to Dublin. The Ilen was discharged at the Port of Dublin 1997, after an absence from Ireland of 70 years.

It was a collaboration between the Ilen Project in Limerick and Hegarty’s Boatyard in Old Court, near Skibbereen. Much of the heavy lifting, of frames, planking, deadwood & backbone, knees, floors, shelves and stringers, deck beams, and carlins, was done in Hegarty’s. The generally lighter work of preparing sole, bulkheads, deck‐houses fixed furniture, fixtures & fittings, deck fittings, machinery, systems, tanks, spar making and rigging is being done at the Ilen boat building school in Limerick.

Ten years. The boat was much the worse for wear when it returned to West Cork in May 1998, and it remained dormant for ten years before the start of a decade-long restoration.

Ilen now serves as a community floating classroom and cargo vessel – visiting 23 ports in 2019 and making a transatlantic crossing to Greenland as part of a relationship-building project to link youth in Limerick City with youth in Nuuk, west Greenland.

At a mere 56ft, Ilen is capable of visiting most of the small harbours of Ireland.
