A naval officer says it is high time that the State defends its critical national infrastructure by protecting the transatlantic cables that pass through Irish waters.

As the Irish Examiner reports, Lieutenant Shane Mulcahy, attached to the Naval Operations Command Centre, said Ireland needs to address the “vulnerabilities” of its undersea cable network, given how dependent our digital economy is on them. He said that around three-quarters of transatlantic cables in the northern hemisphere pass through or near Irish waters, the majority of them along a corridor less than 160km wide.

Lt Mulcahy said these cables are vulnerable to natural hazards, fishing anchors, and more hostile acts, including attack by intelligence or military agencies. He said the cables carry 97% of global data transmissions, with modern satellites accounting for just 3%.

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.
