Ireland is acquiring five Thales-made Ground Master radars — four Ground Master 400 Alpha (GM400α) sensors and one Ground Master 200 Multi‑Mission All‑in‑one (GM200 MM/A) — with first deliveries due next year and a full capability milestone expected before the end of 2028.
Thales, the contract partners, and the stated aim
French manufacturer Thales announced the deal in a company statement after the Irish Department of Defence confirmed the order with France’s Direction Générale de l’Armement (DGA). Thales framed the purchase as support for Dublin’s effort to develop what it called a “first fully Recognised Air Picture.” Martin Soegaard, Thales country director for Denmark, Ireland, Iceland and Baltics, said: “The selection of Thales to enhance Ireland’s sovereign and defence capabilities in a rapidly changing and complex security landscape, underscores our proven ability to deliver advanced air surveillance capabilities.”
Ireland’s enduring primary‑radar gap and the Commission on Defence Forces
The procurement addresses a capability gap identified by Irish defence planning. The 2022 Commission on Defence Forces listed a primary radar capability as a top priority. One submission to the Commission warned that “[c]ontinued incursions by Russian aircraft into Irish controlled airspace highlights the importance of primary radar and the dangers of not having such equipment. The lack of such radar not only highlights a lack of capabilities within the AC/DF [Air Corps/Defence Forces] but also presents a major danger to civilian aircraft.” The sources describe Ireland as a militarily neutral nation pursuing the upgrade to strengthen national awareness, security and sovereignty.

Thales provided specific system descriptions in its statement. The GM400α is noted for portability — it can fit in a 20‑ft ISO container — and for an update rate of six seconds, which the firm said supports “exceptional tracking capability, even in dense clutter.” The GM200 MM/A is described as “field‑proven” and able to “simultaneously” detect and track “low to high‑altitude targets.” Thales said an individual 20‑ft shelter houses the GM200’s radar, mast and power generator unit.
Procurement timeline, budget signals, and the reported price
The company statement put initial deliveries in the next calendar year and Dublin expects to meet a full capability milestone prior to the end of 2028. Irish authorities have not published the acquisition cost; local media, however, reported an estimated figure of €500 million ($563 million). The radar project forms one item in a broader procurement push: Dublin said last year that a “record” €1.5 billion defence budget would allow “significant progress” on the radar project alongside other planned purchases, including Airbus‑produced H145 light utility helicopters.
What this means for the Air Corps/Defence Forces, civilian aviation, and defence planners
- Air Corps/Defence Forces: The five Ground Master radars are intended to provide a primary radar capability that, according to Thales, will enable a Recognised Air Picture — a functional change from the current state in which aircraft without transponders cannot be identified or tracked.
- Civil aviation and the public: The Commission submission explicitly linked the lack of primary radar to risks for civilian aircraft, describing the absence of such equipment as presenting “a major danger to civilian aircraft.” The new radars are presented as addressing that safety concern by improving national awareness of non‑transponder traffic.
- Defence planners and procurement managers: The schedule — first deliveries next year, capability milestone by end‑2028 — and the use of the record €1.5 billion budget indicate the government has allocated resources to this modernization path, even as official price disclosure has not been made public and media have reported a €500 million estimate.
Deliveries beginning next year and the stated end‑2028 milestone mark a clear timeline for closing a high‑profile capability gap identified by the 2022 Commission on Defence Forces. The announced systems — four GM400α and one GM200 MM/A — come with specific performance descriptions from the vendor, while the public record remains incomplete on contract cost. Observers will now be able to watch the arrival and integration of those units against the government’s stated schedule and budget commitments.
