The NH90 helicopter pioneered fly-by-wire controls but struggled with operational readiness and high costs.
In short: As the first production helicopter to utilize a full fly-by-wire system, the NH90 represents a massive leap in aviation technology. Yet, despite its advanced composite design and multi-role versatility, the program has been plagued by maintenance hurdles, soaring operating costs, and early withdrawals by several nations in the mid-2020s.
Conceived in 1985 by a coalition of European nations, the NH90 was designed to meet NATO requirements for a versatile platform capable of both land-based troop transport and maritime anti-submarine operations. The aircraft is defined by its extensive use of composite materials, which provide a lighter, more durable airframe than traditional metal designs. Its most significant technological achievement is the four-channel fly-by-wire flight control system, which allows for greater pilot autonomy and reduced workload. The helicopter is produced in two primary configurations: a battlefield transport version and a naval variant equipped with specialized sensors for search and rescue or submarine hunting.
Despite these innovations, the program faced significant friction during its rollout. Operators in countries like Australia and Norway reported chronic maintenance issues, including compressor blade wear and cabin floor damage from standard military boots. These technical difficulties, combined with high operating costs—which some reports suggested were significantly higher than the older aircraft they replaced—led to low fleet availability. By the early 2020s, these challenges culminated in the early retirement of the fleet in Australia and the termination of the program in Norway. Manufacturers have since launched the New Horizon transformation plan to improve spare part logistics and increase the time between maintenance intervals.
The program remains a complex international effort, with major components produced by various shareholders and final assembly lines located across Europe and Australia. As of early 2026, over 600 units have been produced for more than a dozen nations. While the aircraft has faced criticism for its teething issues, ongoing upgrades—such as the Block 1 software release and structural improvements—aim to extend its service life and enhance its capabilities. The NH90 continues to serve as a primary rotorcraft for many militaries, with manufacturers actively working to address the reliability concerns that have defined much of its operational history.
