The NHIndustries NH90 is a medium-sized, twin-engine, multi-role military helicopter. It was developed in response to NATO requirements for a battlefield helicopter which would also be capable of being operated in naval environments. The NH90 was developed and is manufactured by NHIndustries, a collaborative company, which is owned by Airbus Helicopters, Leonardo (formerly AgustaWestland) and Fokker Aerostructures. The first prototype conducted its maiden flight in December 1995; the type first entered operational service in 2007. As of January 2017, the NH90 has logged 127,000 flight hours in the armed forces of thirteen nations.
The NH90 has the distinction of being the first production helicopter to feature entirely fly by wire flight controls. There are two main variants, the Tactical Transport Helicopter (TTH) for army use and the navalised NATO Frigate Helicopter (NFH); each customer typically has various alterations and customisations made to their own NH90 fleets, such as different weapons, sensors and cabin arrangements, to meet their own specific requirements. In early service, the NH90 has suffered several teething issues, which has in turn delayed active deployment of the type by some operators.

In 1985, France, West Germany, Italy, the Netherlands, and the United Kingdom teamed to develop a NATO battlefield transport and anti-ship/anti-submarine helicopter for the 1990s. The United Kingdom left the team in 1987. On 1 September 1992, NH Industries signed an NH90 design-and-development contract with NAHEMA (NATO Helicopter Management Agency). This agency represented the four participating nations: France, Germany, Italy, and the Netherlands. Portugal later joined the agency in June 2001. Design work on the helicopter started in 1993. The first prototype, PT1, made the type's first flight on 18 December 1995. The second prototype, PT2, first flew on 19 March 1997 and the third prototype, PT3, on 27 November 1998. On 12 December 2002, PT3 became the first helicopter to fly exclusively with fly-by-wire controls following the removal of mechanical back-up controls.
The NH90 was developed into two main variants: the Tactical Transport Helicopter (TTH) and the NATO Frigate Helicopter (NFH). These two main variants share about 75% commonality with each other. Furthermore, many of the operators have requested specific configurations to their own helicopter fleets, thus each nation's NH90 is effectively customized to the end-user's requirements. During the development phase of the programme in the 1990s, both technical and funding problems were experienced. In June 2000, the partner nations placed a large production order, worth US$8.6 billion, for a total of 366 helicopters. Additional orders have since followed from customers in Europe, Asia, and Australia. By April 2013, a total of 529 NH90s of all variants were on order by various customers.
The NH90 was initially intended to be produced at three exporting final assembly lines (FAL); Cascina Costa in Italy for AgustaWestland, Marignane in France and Donauwörth in Germany for Airbus Helicopters. The Nordic and Australian contracts stipulated production locally (the Nordic ones at Patria in Finland and the Australian ones in Brisbane). Spain has a final assembly line at Albacete. The Marignane assembly line can reportedly complete up to 22 NH90s per year.
Major components are produced by each of the shareholding companies:
- Airbus Helicopters France 31.25% (Engines, Rotors, the Electrical, flight control and the core avionics systems)
- Airbus Helicopters Deutschland 31.25% (Forward and centre fuselage, the fuel, communications and avionics control systems)
- Fokker 5.5% (Tail structure, doors, sponsons, landing gear and the intermediate gearbox)
- AgustaWestland 32% (Rear fuselage, main gearbox, hydraulic system, automatic flight control and plant management systems, power plant and the NFH mission system)
Items built by the shareholding companies are then distributed to the six locations for assembly and flight test (Marignane, France; Tessera, Italy; Donauworth, Germany; Halli, Finland; and Brisbane, Australia).
In late 2006, the German Army, the first customer to receive production aircraft, accepted delivery of its first NH90 TTH. In April 2010, the Royal Netherlands Navy was the first customer to receive the navalised NH90 NFH variant. In June 2014, the consortium announced that they had completed delivery of the 200th NH90; at that point, the backlog of orders was reported as reaching out to 2020. In order to alleviate delays and reduce the complexity of manufacturing a large number of NH90 variants, NH Industries proposed the adoption of a simplified baseline airframe which could be configured to the individual customer's requirements. Between 2004 and 2016, the production lead times for the NH90 had reduced from 18 months to 7.5 months.
In 2014, worldwide production of the NH90 peaked at 53 helicopters. In October 2015, the delivery of the 250th NH90 was formally accepted by the Italian Army. In 2015, the rate of NH90 production declined, reportedly due to countries choosing to delay their orders and some contracts having been fulfilled; in 2016, the Finnish final assembly line became the first to close with orders for that line had been completed.
Concerns over performance
In 2010, German newspaper Bild reported that German Army experts had concerns that the helicopter was not yet ready for the transportation of combat troops. They stated that the seats were only rated for 110 kg (240 lb), not considered enough for a fully equipped soldier. Heavy infantry weapons could not be adequately secured and the cabin floor was prone to damage, citing an anecdote of damage caused by footwear. The helicopter could only land on firm ground, with obstacles not exceeding 16 cm (6.3 in). Troops carrying full equipment could not use the rear ramp due to weight-limitations placed on it. Adding a door machine gun was not possible due to space taken by troop ingress and egress; there was also no provision for fast roping or paratroop equipment. In response, the German Defense Ministry proclaimed that this article referred to a prototype, not to the production model; the specifications for which were not even finalised at the time. The prototype evaluation and its results were described as a normal procedure in an ongoing design process.
In November 2011, the MRH90 program was placed on the Australian Department of Defence's "Projects of Concern" list. The most serious problem identified by a diagnostic review, which caused a brief grounding in 2010, is compressor blade rubbing caused by the bending of a spool in the Rolls-Royce Turbomeca RTM322 engine due to uneven cooling after shutdown. Other problems identified include failure of transmission oil cooler fans, windscreen cracking, an inertial navigation system that is slow to align, and the weakness of the cabin floor to withstand the impact of soldiers’ boots – a problem also encountered in German service.
In March 2014, it was announced that a Dutch NH90 had suffered higher than expected fuselage wear and corrosion following an extended deployment at sea; analysis by the Dutch National Aerospace Laboratory attributed the corrosion to design and assembly flaws. In response, NHI Industries launched a corrosion prevention programme and enacted several design modifications. In December 2014, Dutch NH90 deliveries, which had been temporarily halted earlier in the year, restarted after the majority of identified points were addressed and an agreement was made by the manufacturer to bear the cost of developing modifications, repairs, and preventive measures against corrosion.
The NH90 was designed to fulfill a NATO staff requirement for a multi-role, medium-sized military helicopter for both land and maritime operations. According to Flight International, the NH90 has the distinction of being the first helicopter in the world to be developed in line with NATO requirements. As such, the design of the NH90 meets with multiple national and international standards, including military airworthiness processes in Germany, France, Italy, and the Netherlands; conformance with FAR 29 and MIL-STDS design standards, as well as DEF-STN 00-970 icing conditions performance and electro-magnetic compatibility. It is produced in two principle variants, the battlefield Tactical Transport Helicopter (TTH) and the maritime NATO Frigate Helicopter (NFH).
One key innovation of the rotorcraft is the four-channel fly-by-wire control system employed; the NH90 is the first helicopter in the world to be equipped with full fly-by-wire flight controls. A four-axis autopilot is also integrated with the fly-by-wire system, as are mission and navigation systems to enable greater autonomy during operations and to reduce pilot workload. The flight envelope of the NH90 is capable of all-weather day-and-night operations, ship-borne operations during high sea states, across a temperature range from −40 °C to +50 °C, and up to a maximum altitude of 20,000 feet. Power is provided by a pair of turboshaft engines, dependent on customer selection, the NH90 is either fitted with Rolls-Royce Turbomeca RTM322 or General Electric T700E powerplants; exhaust gases from the engines are filtered through an infrared suppression system for decreased sensory visibility. According to Airbus Helicopters, the NH90 possesses the lowest radar signature in its class, principally due to its diamond-shaped composite fuselage.
The NH90 featured an advanced composite airframe, designed for ballistic tolerance, a high level of crashworthiness, lower weight, and 30 per cent greater endurance than a metallic counterpart. The four main rotor blades are also composed of composite materials, increasing fatigue strength and lifespan while providing for greater damage tolerance. The unobstructed main cabin area is entered either by large sliding doors on either side of the fuselage or via a rear ramp, the cabin is designed to accommodate modular equipment packages to enable the rotorcraft to be rapidly reconfigured, providing for operational flexibility. In a troop-transport capacity, the cabin can accommodate up to 20 fully equipped soldiers, or up to 12 stretchers in a medical evacuation role, some light vehicles may also be transported; the main cabin is equipped with environmental control systems and sound proofing measures to improve passenger conditions.
The NH90 can be equipped with various mission-specific systems, including modular armor plating around the cabin area for undertaking high-risk missions and an ice protection system for operations within cold climates. It can also make use of the In-Hover Flight Refuelling System (HIFR) as well as additional internal and external fuel tanks to conduct extended range missions. Other equipment includes a wire strike protection system, rappelling system, hoist, cargo hook, search light and various seating options, including crashworthy foldable seats. For performing maritime operations, such tasked NH90s are typically equipped with the Harpoon deck-locking system, automatic main rotor blade and tail folding mechanisms, and other deck handling systems to conduct all-weather ship-borne operations; it is also typically outfitted with dipping sonar and sonobuoy processing equipment.
The NH90 features a range of customizable avionics systems, dependent on customer selection and purpose. On some models, French firm Thales Group provides various parts of the avionics, such as the glass cockpit, full-colour multifunction displays, tactical mission and encrypted communication systems, the TopOwl helmet-mounted sight/display, IFF and autonomous navigation systems, and the electrical power generation system. Other systems include a forward looking infrared (FLIR), weather radar, digital map generation system, enhanced ground proximity warning system, personal locator system, and VHF/UHF/HF tactical radios. In 2015, the NH90 became the first helicopter to receive an laser-based airborne collision avoidance system. Onboard mission systems feature a dual-redundant databus, are compliant with MIL-STD 1553, and are comprehensively managed via sensor fusion functionality. Customer demand for future avionics improvements such as new data links and communication systems, as well as additional electro-optical sensors, have been anticipated by the manufacturer.
In 2005, Australia ordered 12 aircraft to replace their aging fleet of Army UH-1 Iroquois helicopters. In June 2006, the Australian Defence Force announced plans to replace its UH-60 Black Hawk and Westland Sea King helicopters; a further 34 NH90s were ordered, for an ordered total of 46; four being manufactured in Europe, and 42 being manufactured locally by Australian Aerospace (an Airbus Helicopters subsidiary) in Brisbane. The type is designated MRH-90 Taipan, 'MRH' stands for Multi Role Helicopter. Six rotorcraft are operated by 808 Squadron of the Royal Australian Navy, which was reformed for the first time since its 1958 decommissioning in 2011, and recommissioned in 2013. The other 40 are operated by the Australian Army.
On 20 April 2010, an ADF MRH90 suffered a single engine failure near Adelaide, landing safely at RAAF Base Edinburgh. NHI Industries sent personnel to Australia to investigate the failure. On 18 May the ADF announced that the MRH90 fleet was grounded due to engine issues since the April incident. The cause of the failure was determined as the compressor blade contacting the engine casing, leading to new preventative inspections; flights resumed in July 2010. In June 2011, the NFH variant lost to the Sikorsky MH-60R in competition to replace the Royal Australian Navy S-70B Sea Hawks.
In July 2014, the Australian National Audit Office released a report on the MRH90, citing a series of procurement errors and development deficiencies delaying final operational capability (FOC), originally planned for that month, until April 2019, nearly five years later than planned. Some nine years after the initial contract was signed, the models first delivered in 2007 had not validated any of the 11 set operational capability milestones, and forced redesigns including bolstered cabin floors and windscreens, rappelling hooks, and door gunner positions; obtaining spare parts and sustaining the helicopters has also been more costly. The Australian Army will be forced to operate its aging S-70A Black Hawk beyond their planned retirement date. Due to the delays, Australia will receive an additional helicopter, for a total of 47. By September 2015, most of the MRH90's flaws had reportedly been addressed. In June 2017, the Australian Navy successfully completed trials aboard HMAS Anzac, marking a major milestone in the helicopter programme.
In 2007, Belgium signed on for an order of 10 aircraft, 4 TTH, 4 NFH and an option for 2 TTH. In September 2012, NHI performed the first flight of the Belgium’s Tactical Transport Helicopter (TTH), which is broadly similar to the French NH90 “Caiman” version. In January 2013, eight NH90s were on firm order. On 1 August 2013, Belgium received its first NH90 NFH at Full Operational Capability (FOC). On 23 October 2013, Belgium's first NH90 TTH entered service, the last was delivered on 13 November 2014. From first delivery until the last, three NH90s flew 34 hours a month for a total of 450 flight hours with a 67 percent availability rate, making Belgium one of the type's most intensive users. Two NH90 NFHs for the navy were delivered, the final two were delivered by early 2015 to replace their Westland Sea King helicopters. On 21 August 2015, the Belgian Navy declared its NH90s had attained initial operational readiness; on 28 August 2015, the first rescue mission performed by a Belgian Navy NH90 took place.
In July 2015, the Egyptian Navy entered negotiations for the purchase of 5 NH90 NFH helicopters, these are intended to serve onboard its newly acquired FREMM frigate Tahya Misr and 4 Gowind corvettes that are also on order. The NH90 helicopters will all be of French standard. In October 2015, it was reported that negotiations for a "large quantity" of NH90s had reached an advanced stage.
In October 2001, Finland signed a contract for 20 NH90 TTHs for the Finnish Army to replace their ageing fleet of Mil Mi-8 helicopters. In March 2008, NH Industries began NH90 deliveries to Finland; deliveries had been delayed from an initial 2004 date, to minimize further delay, aircraft were first delivered to an Initial Operational Configuration (IOC-) and Nearly Operational Configuration (IOC+), to be later modified by Patria into a Final Operational Configuration (FOC). In September 2011, the Finnish Defence Forces and Patria signed an agreement to provide ballistic protection for onboard personnel across the NH90 fleet.
In June 2011, nine Finnish NH90s participated in the Finnish Defense Forces' main field exercise, transporting 157 soldiers across 320 kilometers in two rotations; their performance was described as having exceeded expectations. In January 2015, it was reported that Finnish NH90s had been experiencing considerable reliability issues, at one time in 2014 fleet availability dipped to 19%, and some spare parts had up to seven months waiting time. By early 2015, the combined NH90s fleet had accumulated a total of 7,000 flight hours, and had an availability rate of 40%. On 18 June 2015, delivery of the final Finnish NH90 took place. In November 2015, the availability rate was reported as having surpassed 50 percent.
The French government had initially ordered a total of 34 NH90 TTHs, for the ALAT and 27 NFH for the Navy. Both versions will be named "Caïman" and final assembly will be carried out by Airbus Helicopters. The French Army had intended to buy 68 NH90; however, the April 2013 defence review could have cancelled the contract for the second batch of 34. Under the "Bonn rebate" deal, France receives a 12% discount on its 68 Army helicopters; a November 2012 Senate report put the French TTH per unit price at €28.6M after discount, set on the assumption of total orders of 605 aircraft by 2020. Cuts to France's order would result in workshare reallocation; possibly including French Navy NFH90s being assembled in Italy and Fokker performing maintenance of French TTHs. On 29 May 2013, France formally ordered the second batch of 34 NH90 TTHs for just under €1 billion. In January 2016, France placed an order for six additional NH90 TTHs.
The French Army took delivery of its first NH90 TTH in December 2011. On 21 December 2012, the French Navy received their first NH90 NFH in final operating capability. In December 2010, the NH90 formally achieved in-service status with the French Navy, being initially used to perform search and rescue and maritime counter-terrorism operations. The first seven aircraft were delivered to an interim "Step A" configuration; following aircraft were delivered to the "Step B" standard and are forecast to be delivered at a rate of two per year until 2020. The French Navy formally cleared the type to perform anti-surface warfare duties in 2012, clearance to perform anti-submarine warfare missions followed in 2013, allowing the NH90 to take over the missions previously performed by the Navy's Westland Lynx and Aérospatiale Super Frelon helicopter fleets.
On 3 November 2014, the French Army Light Aviation deployed two of its NH90s to Mali; both helicopters had been fitted with three additional fuel tanks to fly the four-day ferry flight to the region. In June 2015, it was announced that plans for French special forces to operate NH90s had been accelerated, and that the 4th Special Forces Helicopter Regiment were to assist in defining the need for customisations to the type for undertaking special operations. In January 2016, it was reported that Australia and France were studying a potential joint requirement for a dedicated variant of the NH90 special forces; these are to replace French Navy Eurocopter EC725s in this capacity. According to Vincent Dubrule, president of the NHI consortium, the special forces variant concept has, in addition to Australia and France, drawn interest from Germany, Italy and New Zealand.
The German Army chose to procure the troop transport variant. The first three serial production NH90s were delivered to the German Army in December 2006. By January 2013, a total of 80 aircraft were on order for the Army. In 2009, the German Navy were also considering the procurement of up to 30 NFH for their new Maritime Helicopter. In March 2013, the German government chose to reorganise the NH90 procurement; the Army's fleet of 122 NH90s was reduced to 82; 18 NH90s previously ordered for the German Army were converted to the NFH maritime variant for the Navy instead. On 26 June 2013, the German defense committee declared that the order for a combined 202 NH90 and Tiger helicopters were to be reduced to 157. In December 2014, Germany announced that, in addition to the 80 troop transports firmly on order, it was considering an option for an additional 22 NH90s; it was investigating the possibility of setting up a multinational helicopter unit to operate these 22 helicopters as a shared NATO resource with other nations using and contributing to the force.
In July 2012, the German NH90 fleet reached a combined total of 5,000 flight hours. In April 2013, up to 4 German Army NH90 TTH were deployed in Afghanistan in a Forward Air Medical Evacuation role in support of coalition forces operating in the country. On 23 June 2013, German Army NH90s were declared operationally capable of medical evacuation operations. Following an engine failure and controlled crash in Uzbekistan in July 2014, the German Army temporarily grounded the type for investigation. In December 2015, it was announced that production of the German Navy's variant of the NH90 NFH, named Sea Lion, had formally commenced; a refit of the German Army's TTH variant was also underway at the same time. Since late 2014, Germany has promoted the establishment of a multinational NH90 force for combat MEDEVAC missions, the taskforce may comprise up to 20 NH90s.
The Navy's version, known as the NH90 Sea Lion, is based on the NH90 NFH. Its 18 NH90 Sea Lions are equipped with improved navigation and communications equipment permitting operation within civil airspace, along with additional sensors for military missions. The identification friend or foe system was also updated. Designed to replace Germany's Sea Kings, the Sea Lion is to be enter service with the Navy by 2019. The Sea Lion first flew on 8 December 2016.
In August 2003, Greece ordered 20 NH90s with an option for 14 more. In early 2013, the German newspaper Bild alleged that Airbus officials paid € 41 million in bribes to Greek officials to secure the order; Airbus stated that the claim was "groundless". On December 12 it was stated that deliveries would start again after an embargo by the Hellenic Government with 4 helicopters being of the SPEOPS specification.
In June 2000, Italy signed an initial contract for a batch of 60 TTH (Tactical Transport Helicopter) for the Italian Army, along with a further 46 NFH (NATO Frigate Helicopter) and 10 TTH for the Italian Navy. On 30 December 2007, the first NH90 TTH was formally handed over to the Italian Army. On 23 June 2011, the Navy received its first NH90, which was delivered to an interim MOC (Meaningful Operational Capability) standard, capable of performing training, search and rescue, and utility operations; anti-submarine and anti-surface warfare capabilities were not initially available until aircraft are retrofitted to a FOC (Final Operational Capability) standard. In May 2013, the Italian Army took delivery of the first NH90 TTH of a FOC standard; in November 2013, the Italian Navy took delivery of their first FOC-standard NH90 NFH.
In 2012, Italy deployed a total of 5 Army NH90 TTHs to support troops participating in the International Security Assistance Force in Afghanistan. The NH90s, which were air-transported individually by allied Boeing C-17 Globemaster III cargo aircraft, replaced six Agusta/Bell 205s in performing tactical transport and medevac operations; Army Aviation Commander Gen. Enzo Stefanini stated that "...in Afghan conditions, the NH90 is delivering performance 15 percent above what was envisaged".
The Netherlands, one of the original supporters of the programme, has 20 units on order: 12 NFH for the Royal Netherlands Navy, and 8 TNFH for the Air Force. In 2010, the Royal Netherlands Navy became the first customer to receive the NFH variant.
In 2009, concerns surfaced that design changes had made the helicopter too heavy to operate from Dutch frigates for which they were ordered. In June 2014, the Dutch government decided not to accept the last batch of 7 NH90s due to some 100 shortcomings found in relation to the design, manufacturing and material choice of the aircraft, in particular corrosion in the presence of salt water. In December 2014, NH90 deliveries restarted after the Dutch government came to an agreement with the manufacturer, under which modifications and necessary repairs against corrosion would be made at the manufacturer's cost; 75 of the 100 shortcomings were also reported as having been solved.
In April 2013, the Navy deployed the type onboard HNLMS De Ruyter to fight piracy in the Gulf of Aden. In November 2014, the Royal Netherlands Navy deployed a single NH90NFH to Somalia to support Operation Atalanta in Somalia.
In July 2006, the New Zealand Government signed a NZ$771 million (~€500M) contract to purchase eight NH90s (plus one extra for spares) to replace the Royal New Zealand Air Force's (RNZAF) fleet of 13 UH-1 Iroquois. For ease of manufacture and logistics, New Zealand deliberately chose their NH90 configuration to be nearly identical to the larger Australian fleet. On 7 December 2011, deliveries to New Zealand formally began with the first two NH90s being airlifted by a leased Antonov An-124 cargo aircraft to RNZAF Base Ohakea. In February 2013, the first phase of the RNZAF's operational evaluation of the NH90 was completed, clearing the type to begin operational duties.
Between September 2013 and July 2014, the first four delivered NH90s were retrofitted to a final operational configuration; later aircraft were already delivered to this standard. On 31 October 2014, the RNZAF announced that they had received into service the last of the eight NH90 TTHs. Following command structure changes in December 2014, the NH90 fleet was tasked with additional responsibilities, including casualty evacuation during search and rescue operations and providing transport services to the New Zealand Police and other government personnel. In April 2015, Defence Minister Gerry Brownlee questioned the inability of the NH90 fleet to contribute to relief efforts in the aftermath of Cyclone Pam, revealing that the fleet may be refitted with an automated blade and tail folding system to better enable ship borne deployments in the future.
After the Kaikoura earthquakes in November 2016, the NH90s were critical in delivering aid and supplies to the area.
In April 2017, the RNZAF's NH90 fleet was grounded following an in-flight single engine failure which forced an emergency landing.
In December 2011, the first Norwegian NH90 helicopter was delivered. In July 2012, the Norwegian Deputy Defence Minister Roger Ingebrigtsen announced that "once our current Westland Lynx helicopters reach their end of life in 2014, we are going to have replacement helicopters on our naval vessels. If the NH90 hasn’t been delivered, we will purchase another helicopter...considering that the aircraft were to be delivered by 2005, and that delivery is yet to start by 2012, our confidence in the producer isn't exactly on the rise" In August 2012 it was reported that the Royal Norwegian Air Force would be recommending that the Department of Defence contact Sikorsky to verify whether versions of the H-60 Seahawk, specifically the MH-60R, would be a viable alternative to the NH-90 in the anti-submarine warfare (ASW) role. Defence Minister Espen Barth Eide stated "We still believe the marine version of the NH90 to be the optimal platform, and we hope to purchase it, but there are limits to our patience." By January 2013, Norway had ordered a total of 14 NH90s. In January 2016, six of the 14 aircraft had been delivered.
In July 2004, the Sultanate of Oman issued an order for a total of 20 NH90 TTHs for the Royal Air Force of Oman (RAFO). To cope with the extreme flight conditions of the Middle East, RAFO NH90s are equipped with enhanced power plants; the type is to replace the Agusta/Bell 205A and Agusta/Bell 212 used for tactical transport and search and rescue operations. On 23 June 2010, the first two NH90 TTHs were delivered to the RAFO at Musana Air Base. By July 2012, ten NH90s had been delivered to the RAFO; in Omani service, the NH90 has established an endurance record, flying 700 nautical miles without refueling during a 5-hour 21 minute-long mission.
In 2014, Qatar announced that it would invest in NH90 helicopters for $2.76 billion.
On 20 May 2005 the Council of Ministers authorised the acquisition of 45 NH90 TTHs; in December 2006, it was announced that a procurement contract for the Spanish Armed Forces had been signed. The Spanish NH90 variant features domestically assembled General Electric CT7 8F5 engines, customised communications suite, and Indra-developed electronic warning systems. The original budget for the procurement was for €1,260 million; by 2010, this had grown to €2,463M. In June 2012, it was announced that Spain was negotiating to cut their purchase to 37 aircraft. On 18 December 2014, Spain took delivery of the first NH90 TTH, which had been assembled at Airbus Helicopters Albacete facility; by this point, the order had been reduced to a total of 22 NH90s of the TTH variant.
In 2001, Sweden signed a contract for 18 NH90 TTH, made up of 13 TTT[i]/SAR and 5 SAR/ASW to be operated by the Swedish Air Force. Because of renewed foreign submarine activity at the Swedish coast in 2014 it was decided in 2015 that four TTT/SAR would be modified to SAR/ASW in order to increase the anti-submarine warfare capability, so there will be 9 TTT/SAR and 9 SAR/ASW. The NH90 is known as the Helikopter 14 (HKP14) in Swedish service, the FOC version of TTT/SAR are designated HKP14E and the FOC version of SAR/ASW are designated HKP14F.
By November 2015, Sweden had ordered 18 NH90s with ten helicopters delivered. Sweden did not expect their NH90s to be operational until 2020 and ordered 15 UH-60M Black Hawks in 2011, Sweden deployed four of their new Black Hawks to Afghanistan in March 2013. In December 2015, the first Swedish NH90 in a full ASW configuration was delivered.
Portugal was the fifth nation to join the programme with an order for ten transport NH90 in June 2001; it was intended for these to equip the Portuguese Army Light Aviation Unit. However, in July 2012, fiscal consequences of the Great Recession led Portugal to cancel the order, despite having already spent €87m on the project, in order to save another €420m in acquisition and running costs to 2020.
- Saudi Arabia
In July 2006, the Saudi Government agreed to purchase 64 NH90s. Then in October 2007 the government changed its plans, and agreed to buy 150 Russian-made Mi-35 and Mi-17 helicopters instead.
NFH: NATO Frigate Helicopter
The primary role of the NFH version is autonomous anti-submarine warfare (ASW) and anti-surface unit warfare (ASuW), mainly from naval ships. These aircraft are equipped for day and night, adverse weather and severe ship motion operations. Additional roles include anti-air warfare support, vertical replenishment (VERTREP), search and rescue (SAR) and troop transport. France are splitting their purchase between the "NFH version combat" costing €43.3m in FY2013 and the "NFH version soutien" (support) at €36.4m in FY2013.
- NH90 NFH Caïman
- French Navy designation for NH90 NFH.
