Advancements in Radar Technology: The Grifo EK Collaboration Between Leonardo and Hanwha Systems
The defense exhibition in Seoul recently showcased an advanced iteration of the Grifo radar system, prominently displayed in the Hanwha Systems area of the expansive Hanwha Group booth. This new variant, designated as the Grifo EK, emerges from a strategic partnership between the Italian aerospace giant Leonardo and Turkey’s defense industry.
Historical Context of Collaboration
Leonardo and Hanwha Systems have maintained a collaborative relationship since 2017, initially focusing on Infrared Search and Track (IRST) technologies. Their partnership has evolved notably, culminating in a Memorandum of Understanding (MoU) signed on June 23, 2024, during the Farnborough International Air Show. This agreement aims to jointly engineer an air-cooled Active Electronically Scanned Array (AESA) radar.
- MoU Highlights:
- Joint development of AESA radar technology.
- Potential integration into the Light Combat Aircraft (LCA), specifically the FA-50 variant.
Technical Developments and Adaptations
The Grifo EK radar, characterized by its dual branding from both companies, signifies the successful melding of Leonardo’s robust backend systems and algorithms with Hanwha’s design capabilities. The core components of this radar system are primarily produced in Northern Italy’s Nerviano facility, with the AESA antenna being fabricated at Leonardo’s Edinburgh site in Scotland.
- Key Features:
- Composed of 600 transmit/receive modules.
- Compatible with various medium-light aircraft, although limited by size in smaller platforms.
Recognizing the need for adaptability in modern threats, Hanwha Systems is innovating a minimized antenna with just 450 modules, leveraging low-power Gallium Nitride technology. This design not only streamlines integration but also enhances the radar’s operational efficiency.
Integration Timeline and Future Prospects
Industry sources indicate that the developmental phase for the Grifo EK has concluded, with final testing set to occur following the ADEX exhibition. The radar components will be transported to Italy for full integration, where they will undergo further evaluations at Leonardo’s laboratory. Subsequently, the radar will be fitted into a pod for airborne trials on Leonardo’s test aircraft.
- Projected Timeline:
- Testing completion expected by late 2026, leading to integration into both companies’ product lines.
The Grifo EK is designed not only for new aircraft installations but also targets the lucrative mid-life upgrade sector. Its software architecture will enable progressive updates and tailored functionalities to meet varied operational requirements.
A Legacy of Innovation
This radar represents a critical element in the lineage of Grifo systems, which boasts over 450 units delivered worldwide and has accumulated in excess of 100,000 operational flight hours. Noteworthy is the fact that the Grifo EK is fully ITAR-free, enhancing its appeal to a wider array of international clients.
Beyond the radar sector, Leonardo and Hanwha are also collaborating on the ambitious KF-21 fifth-generation fighter jet program. This aircraft will incorporate a cutting-edge 1,000-element antenna, reflecting the expertise both firms bring to modern aerial combat systems.
Expanding Horizons in Electro-Optic Technologies
The successful collaboration in radar technology has paved the way for further initiatives. On October 22, 2025, during ADEX, both companies formalized another MoU aimed at exploring opportunities in the electro-optic and infrared domains for applications in both land and air platforms. This agreement reinforces the potential for future synergies and highlights the dynamic nature of their partnership.
In summary, the collaboration between Leonardo and Hanwha Systems epitomizes a modern approach to defense technology development, marking a significant step forward in radar capabilities and joint innovation in the defense sector. As global security challenges evolve, such partnerships will be critical in ensuring that military technologies remain cutting-edge and adaptable.
