Irish corps fighter jets?

Ireland is set to make a historic shift in its air defense strategy with plans to acquire combat jets and implement a long-awaited national radar system. This move signals the end of the country’s long-standing dependence on the United Kingdom for aerial protection.

Since the dissolution of the Irish Air Corps’ Light Strike Squadron in 1998—previously equipped with aging French Fouga CM170 Magister jets—Ireland has been without a dedicated combat aircraft fleet. The nation also lacks a primary radar system, leaving its airspace vulnerable. In the absence of these capabilities, a covert bilateral agreement has allowed the UK’s Royal Air Force (RAF) to handle airspace interceptions and respond to aerial threats within Irish territory.

Former Irish Air Corps chief, General Ralph James, has described this reliance on a foreign military, combined with the lack of radar coverage, as making Ireland “arguably the most vulnerable” country in Europe. Speaking at the Slándáil 2020 security summit, James emphasized that neutrality is not a substitute for an actual defense strategy, warning that Ireland must have the ability to control its airspace in any future conflict.

A February 2022 report by the Commission on the Defence Forces recommended that Ireland bolster its air combat and interception capabilities through the acquisition of a dedicated squadron of fighter jets. The report cautioned that without this enhancement, the country would remain “without a credible military capability to protect Ireland, its people, and its resources for any sustained period.”

At present, the Irish Air Corps relies on a fleet of eight Pilatus PC-9M trainer aircraft as its primary aerial response force. These planes, introduced in 2004 and primarily used for pilot training, can be armed with FN HMG machine guns and LAU-7 rocket pods for close air support (CAS). However, their maximum speed of 320 knots (approximately 592 km/h) significantly limits their effectiveness for interception missions.

Government Plans for Fighter Jets and Radar Infrastructure

The Irish government’s new defense investment, first reported by The Irish Times, is aimed at addressing these concerns. Tánaiste and Minister for Defence Simon Harris has requested a full cost analysis and implementation timeline for acquiring a fleet of at least eight combat aircraft, with a preferred target of 12 to 14 jets.

The projected cost of acquiring and maintaining the aircraft is estimated at €60 million to €100 million annually over a 20- to 25-year period, potentially reaching a total expenditure of €2.5 billion. Initial pilot training is expected to take place overseas, while civilian contractors would likely handle aircraft maintenance. The specific jet models under consideration have not been disclosed.

Strategically, Shannon Airport (SNN) has been identified as the likely base for these jets due to its extended runway and proximity to Ireland’s western airspace, an area that has experienced repeated incursions by Russian military aircraft in recent years.

This decision builds upon Ireland’s 2022 commitment to developing its first primary surveillance radar system, a critical capability the country has never previously possessed. Estimated to cost approximately €300 million, the system will feature a detection range of at least 370 kilometers and will be installed across three key locations. Full operational capability is expected by 2028, enabling Ireland to monitor and track suspicious aircraft and drones within its airspace.

Ireland’s Move Toward Independent Air Policing

These defense initiatives represent a major milestone in Ireland’s military development, providing the country with its first independent air policing capability in more than 25 years.

In the past, some policymakers considered the possibility of international air policing arrangements similar to NATO’s Baltic Air Policing mission, which safeguards the airspace of Estonia, Latvia, and Lithuania. However, as a non-NATO member, Ireland may not have access to such agreements. Instead, the government appears committed to strengthening its own national air defense framework, ensuring the country can protect its airspace without reliance on external military forces.

The Irish Air Corps: History, Structure, and Modern Capabilities

The Irish Air Corps (An tAerchór) serves as the aerial branch of Ireland’s Defence Forces, playing a critical role in national security, emergency response, and support for the Army, Naval Service, and Garda Síochána. Despite its relatively small size, the Air Corps has evolved significantly over the past century, developing capabilities in reconnaissance, transport, air support, and maritime patrol. Based at Casement Aerodrome, Baldonnel, it currently operates with 689 active personnel, though its intended strength is 866 personnel as of December 2023.

Unlike the Army or Naval Service, the Air Corps does not have a reserve component, making its active personnel and fleet of 23 aircraft crucial to fulfilling its missions. The branch is headed by Brigadier General Rory O’Connor, and its official motto, “Watchful and Loyal” (Forḟaire agus Tairiseaċt), reflects its commitment to safeguarding Irish airspace.

Origins and Early Years

The origins of Ireland’s air defense can be traced back to the National Army Air Service, the country’s first aerial military unit. During the Anglo-Irish Treaty negotiations in 1921, a Martinsyde Type A Mark II biplane was acquired as a contingency plan to evacuate Michael Collins in case talks failed. Though never used for this mission, it became the first aircraft of the National Army Air Service upon its arrival in June 1922.

Formally established in July 1922, the service gradually expanded with aircraft acquired from the Royal Air Force (RAF) and the Aircraft Disposal Company, which managed surplus aircraft after World War I. By the end of 1922, it had grown to a fleet of ten aircraft, including six Bristol F2B fighters and four Martinsyde F4 Fighters, supported by a force of 400 personnel.

Following the Irish Civil War, the unit was restructured in 1924 and officially renamed the Irish Army Air Corps, marking the beginning of a more organized and enduring aerial defense force.

Development and World War II (“The Emergency”)

With the establishment of the Defence Forces in 1924, the Air Corps initially functioned as part of the Army. It acquired new aircraft over the years, including Gloster Gladiator biplane fighters in 1938. Before the outbreak of World War II, Ireland sourced various aircraft from the UK, including Avro Anson patrol bombers, Supermarine Walrus amphibians, Westland Lysander reconnaissance planes, and several trainers.

During World War II, referred to in Ireland as “The Emergency,” the Air Corps focused on national defense and airspace monitoring. Though there were no recorded engagements with enemy aircraft, the Corps was tasked with shooting down escaped barrage balloons that drifted into Irish airspace. Ireland’s neutrality meant direct military aid was limited, but in 1941, the UK supplied 13 Hawker Hector bombers.

The Air Corps’ air defense capabilities improved significantly between 1943 and 1945, with the delivery of Hawker Hurricane Mk I and Mk II fighters from RAF surplus stocks. These aircraft, reaching speeds of over 300 mph, provided the Air Corps with its first modern fighters. At its peak, 20 Hurricanes were in service.

Throughout the war, 163 foreign aircraft force-landed in Ireland, some of which were integrated into the Air Corps fleet, including a Lockheed Hudson, a Fairey Battle, and three additional Hawker Hurricanes.

The Cold War Era and Expansion

Following the war, the Air Corps upgraded to Supermarine Seafires and Spitfire trainers. In 1956, it entered the jet age with the acquisition of de Havilland Vampire T.55 trainers, later supplemented by Fouga CM.170 Magisters in the 1970s. The Magisters, acquired secondhand from France, became the backbone of the Air Corps’ jet training and light strike capabilities.

The Cold War period saw a shift toward aerial surveillance and maritime patrol. In 1972, amid growing tensions in Northern Ireland, the Air Corps introduced eight Reims-Cessna FR.172H reconnaissance planes for patrol missions. In 1994, two CASA CN235-100MP Persuader aircraft were introduced to bolster Ireland’s maritime surveillance capabilities.

The Air Corps also played a unique role in Ireland’s film industry during the 1960s and 70s, with its aircraft and personnel featuring in productions like The Blue Max, Von Richthofen and Brown, and Zeppelin.

Modernization and Structural Changes

In 1998, the retirement of the Fouga Magister jets left Ireland without a combat-capable fighter aircraft. A government-commissioned Price Waterhouse review recommended acquiring light strike/trainer aircraft, which led to the introduction of eight Pilatus PC-9M aircraft in 2004. These were Ireland’s first aircraft with ejection seats since the Vampire jets.

The Air Corps further modernized in the 2000s, acquiring Pilatus PC-12NG surveillance aircraft, Eurocopter EC135s, and AgustaWestland AW139 helicopters. These aircraft enhanced troop transport, air ambulance, reconnaissance, and emergency response capabilities.

The Air Corps also played a role in ministerial transport, operating aircraft like the BAe 125-700, Beechcraft Super King Air 200, and Gulfstream IV. However, concerns over government spending led to a reduction in ministerial air transport operations.

2022 Defence Forces Commission and Future Plans

In February 2022, the Commission on the Defence Forces released a report calling for the expansion and modernization of Ireland’s air capabilities. The report proposed renaming the Air Corps to the Irish Air Force and establishing an independent Chief of the Air Force.

The report outlined three potential Levels of Ambition (LOA) for the future:

• LOA 1: Maintain the current force size while addressing recruitment shortfalls.
• LOA 2: Expand capabilities with primary radar, additional medium helicopters, strategic airlift, and an anti-drone system.
• LOA 3: Introduce fighter jets, troop carrier aircraft, and combat search-and-rescue (CSAR) helicopters for greater self-sufficiency and international deployment.

The Irish government has committed to implementing LOA 2 by 2028, allocating €1.5 billion for upgrades. LOA 3, which would involve acquiring jet combat aircraft, would require a €2.97 billion budget.

As part of these plans, Tánaiste Simon Harris has requested a full evaluation of the costs and logistics of acquiring at least eight combat jets, with the potential for 12 to 14 aircraft. Shannon Airport has been identified as a possible fighter jet base, particularly given the increased Russian air activity off Ireland’s western coast.

Additionally, Ireland is investing €300 million in its first primary surveillance radar system, scheduled for completion by 2028. The radar system will provide airspace monitoring over a 370-kilometer range, ensuring better detection of potential threats.

Conclusion: The Future of Ireland’s Air Defence

The Irish Air Corps has undergone significant changes since its inception, evolving from a small post-independence force into a modern aerial defense unit. However, challenges remain, particularly in personnel retention and combat capability. The planned acquisition of combat aircraft and radar infrastructure represents a historic turning point, moving Ireland toward greater self-reliance in air defense.

With these upgrades, the Air Corps is set to become a more capable force, ensuring that Ireland’s airspace is protected without reliance on external military assistance. If current modernization efforts continue as planned, Ireland may soon establish its first independent air policing capability in over 25 years
