Aix en Provence, France 3rd August 2026 – NHIndustries (NHI), together with the NATO Helicopter Management Agency (NAHEMA), proudly announces the successful completion of the first flight of the NH90
Software Release 3 (SWR3) configuration,
also dubbed ‘Block 1’. The flight took place on the 21st July in Italy, where an
Italian Navy SH90 helicopter was upgraded to the new SWR3 standard.
This important achievement marks the beginning of the flight test campaign for the SWR3 configuration and represents a major milestone in the evolution of the NH90 programme. It comes only two years after the signature of the landmark contract between NAHEMA and NHIndustries for the development and qualification of the SWR3 standard, reaffirming the shared commitment of the participating Nations and industry Partners to continuously enhance the operational capabilities of the NH90 fleet.
A MAJOR STEP FORWARD FOR THE NH90 PROGRAMME
Software Release 3 represents one of the most significant capability upgrades introduced to the NH90 in recent years. It will implements major operational improvements for both NH90 variants, the Tactical Transport Helicopter (
TTH) and the Nato Frigate Helicopter (
NFH). Developed through the close collaboration of the NHI Partner Companies—Airbus Helicopters, Leonardo and GKN Aerospace, SWR3 positions the NH90 to meet and exceed the most demanding NATO future mission requirements.
The new configuration introduces a range of advanced technologies, including amongst others :
- the world’s first airborne Link 22 capability integrated on a helicopter,
- a next-generation high-definition Electro-Optical Observation System (LEOSS-T),
- enhanced antisubmarine Sonar capabilities with the OTS-90 Mark II and FLASH Sonars,
- an upgraded civil GNSS/FMS navigation system,
- the integration of additional weapon capabilities.
SWR3 significantly strengthens mission performance across the full spectrum of maritime operations. The introduction of Link 22 provides secure Line-of-Sight (LOS) and Beyond-Line-of-Sight (BLOS) communications without relying on satellite connectivity, making the NH90 the first and only helicopter capable of operating with this NATO-standard tactical data link. This breakthrough considerably enhances real-time information exchange and interoperability in increasingly complex multi-domain operational environments.
The integration of the latest high-definition electro-optical and sonar technologies further improves long-range surveillance, target detection, identification, acquisition and tracking. Combined with the NH90’s advanced naval mission system, these new capabilities reduce crew workload while increasing mission effectiveness during demanding operations such as Maritime Security Operations, Search and Rescue, Anti-Surface Warfare and Anti-Submarine Warfare.
The first flight marks the successful integration of these new systems and represents an important step towards the qualification and entry into service of the SWR3 configuration.
