Tánaiste Simon Harris says Ireland must strengthen its defence and security capabilities as the State faces growing risks to maritime security, critical infrastructure and national institutions. He stressed that increased investment would not mean joining a military alliance or abandoning Ireland’s policy of military neutrality.
Breaking News: Harris outlines case for more defence spending
Speaking at an Economic and Social Research Institute event on budgetary policy, Mr Harris said the Government had a responsibility to protect citizens, public institutions and the infrastructure on which Irish livelihoods depend.
He argued that Irish people understand why additional spending on defence and security may be necessary, although Ireland’s defence budget has risen from a relatively low base. The Government is continuing to consider how personnel, equipment and new capabilities can be funded while managing wider public spending pressures.
The remarks come as Irish defence planning faces several competing demands, including maritime surveillance, protection of undersea infrastructure and the modernisation of the Defence Forces.
Key points from the Tánaiste’s comments
- Ireland is not seeking to join a military alliance.
- The State is open to greater European co-operation on information sharing and equipment procurement.
- Maritime security is both a national responsibility and a European concern.
- Ireland could consider borrowing through the EU’s Safe defence investment programme.
- Proposed changes to the triple lock would not, according to Mr Harris, alter military neutrality.
Why maritime security is becoming a central issue
Ireland’s location in the Atlantic gives maritime security particular importance. Undersea cables and other offshore infrastructure support communications, trade, energy systems and the wider economy. Damage or disruption could affect households, businesses and public services even when an incident occurs far from land.
Mr Harris said Ireland must ensure its waters are not used for illegal activity or by hostile states. That requires surveillance, intelligence co-operation and equipment capable of identifying and responding to threats.
The issue also has a European dimension. Ireland can co-operate with other EU member states without becoming part of a military alliance, including through information exchange and joint purchasing arrangements.

Ireland’s involvement in the EU Safe programme
The EU’s Safe programme is designed to support defence investment, including through co-operative procurement and potential loans. Ireland has already opted into elements involving information exchange and common procurement with other European countries.
However, the State has not yet taken up the programme’s loan facility. Mr Harris indicated that borrowing could be considered if it helped accelerate the purchase of important equipment while remaining consistent with Ireland’s budgetary position.
The decision would involve weighing the urgency of defence upgrades against debt, fiscal rules and other demands on the Exchequer. Any borrowing would also need to demonstrate clear value for money and a defined strategic purpose.
Defence Forces face spending pressures
The discussion takes place against a backdrop of savings and delays within the defence portfolio. Measures aimed at reducing departmental costs included changes affecting rations for young military officers studying at university in Galway.
Key investments, including naval radar systems and new helicopters, are also understood to have been delayed amid wider spending pressures. These delays have sharpened questions about whether existing Defence Forces capabilities are sufficient for the risks Ireland may face.
Modern equipment is only one part of the picture. Recruitment, retention, training and the availability of specialist personnel are also essential to maintaining a credible national security response.
What would changing the triple lock mean?
The Government plans to introduce legislation to end the current system known as the triple lock. Under that arrangement, the overseas deployment of Irish troops requires approval from the Cabinet, the Oireachtas and the United Nations Security Council.
Mr Harris said reform would not change Ireland’s military neutrality or lead to membership of a military alliance. He said decisions on deploying Defence Forces personnel would remain with the Irish Government and Dáil Éireann, subject to the UN Charter and international law.
The Government’s position is that no foreign power should have a veto over Ireland’s sovereign decision to contribute to international peacekeeping. The proposed reform is likely to remain politically sensitive because it touches on neutrality, international obligations and the role of the United Nations.
What happens next?
The Government is expected to continue assessing defence investment alongside its medium-term spending plans and EU fiscal rules. A decision on whether to use the Safe loan facility would be significant because it could affect the pace of procurement.
Future attention is likely to focus on:
- The publication and progress of legislation on the triple lock.
- Whether Ireland applies for loans under the EU defence programme.
- The timetable for naval radar and helicopter procurement.
- Funding for recruitment, training and Defence Forces personnel.
- How the Government balances security needs with other public services.
Frequently asked questions
Is Ireland joining a military alliance?
No. Simon Harris said Ireland is not proposing to join a military alliance and that greater European co-operation would not change the State’s military neutrality.
What is the Safe programme?
Safe is an EU defence investment programme that supports co-operation between member states, including common procurement and a potential loan facility.
Why does Ireland need more defence investment?
The Government points to maritime security, illegal activity in Irish waters, protection of critical infrastructure and wider national security challenges.
Will triple-lock reform allow the Government to deploy troops without approval?
The proposed legislation would change the existing approval framework, but Mr Harris said decisions would remain with the Irish Government and Dáil Éireann and would follow international law.
Conclusion
This Breaking News Ireland development highlights a major debate about how a militarily neutral country should protect its people, waters and infrastructure. The Government’s argument is that stronger defence capabilities can coexist with neutrality, provided Ireland retains control over its own decisions.
The immediate test will be whether ministers can turn that argument into a credible, affordable programme covering equipment, personnel and maritime protection. As the debate continues, defence spending and triple-lock reform are set to remain important themes in Ireland Headlines and national politics.
