The NH90 helicopter has completed its first flight in the new Software Release 3 (SWR3) configuration, marking the start of a flight test campaign for one of the platform’s most significant capability upgrades. The milestone flight took place on 21 July in Italy using an Italian Navy SH90 helicopter upgraded to the new standard, according to NHIndustries (NHI).
The achievement comes two years after the NATO Helicopter Management Agency (NAHEMA) and NHIndustries signed a contract to develop and qualify the SWR3 standard. The programme aims to enhance the operational capabilities of the NH90 fleet operated by several NATO and partner nations.
SWR3, also known as Block 1, introduces a broad range of upgrades for both the Tactical Transport Helicopter (TTH) and NATO Frigate Helicopter (NFH) variants. Airbus Helicopters, Leonardo and GKN Aerospace developed the software through the NHIndustries partnership.
Among the most notable additions is the integration of Link 22, making the NH90 the first helicopter to operate with the NATO-standard tactical data link. The capability enables secure line-of-sight and beyond-line-of-sight communications without relying on satellite connectivity, improving interoperability and real-time information sharing during multinational operations.
The upgrade also introduces a high-definition LEOSS-T electro-optical observation system, enhanced anti-submarine warfare capabilities through OTS-90 Mark II and FLASH sonars, an upgraded GNSS/FMS navigation suite and support for additional weapon integrations. Together, these improvements strengthen surveillance, target acquisition and mission effectiveness while reducing crew workload across maritime security, search and rescue, anti-surface warfare and anti-submarine warfare missions.
Michael Kohlhaas, General Manager of NAHEMA, said the successful flight demonstrated effective cooperation between the agency, participating nations and industry partners while keeping the programme on schedule. NHIndustries Managing Director Cristian Naso described the milestone as evidence of Europe’s continued investment in advanced military helicopter capabilities and said the new technologies would help ensure the NH90 meets future operational requirements.
According to NHIndustries, the successful first flight clears the way for the SWR3 qualification programme before the upgraded configuration enters operational service.
