NH90 NFH NATO Frigate Helicopter
The Nato frigate helicopter (NFH) is one of two versions of the NH90 twin-engine multirole helicopter being developed by NH Industries. The other version is the NH90 TTH tactical transport helicopter.
NH Industries, the prime contractor for the programme, is a joint venture company owned by AgustaWestland (32%) of Italy, Eurocopter (62.5%) and Stork Fokker (5.5%) of the Netherlands. Eurocopter is a subsidiary of EADS (European Aeronautics Defence and Space) company formed by DaimlerChrysler Aerospace of Germany, Aerospatiale Matra of France and CASA of Spain.
NH90 NFH NATO frigate helicopter roles
The primary missions of the NH90 NFH helicopter are in the autonomous anti-submarine warfare (ASW) and anti-surface ship warfare (AsuW) role.
In a typical four-hour 'relocation on call' operation, the helicopter would take: 35 minutes to reach the area of operation; 20 minutes releasing sonobuoys; two hours on surveillance in the area of operations; 30 minutes releasing torpedoes; and 35 minutes to return to ship and land, with 20 minutes in reserve.
In a typical four-hour 'screening' operation, the helicopter would take: 15 minutes to reach the area of operation; three hours and 30 minutes in the operations zone carrying out 11 consecutive cycles of ten-minute sonar dipping; and 15 minutes to return to the ship and land, with 20 minutes reserve.
In the anti-surface warfare role, the helicopter is capable of detection, tracking, classification, identification and attack of hostile ships, and has over-the-horizon capability. Secondary roles include anti-air warfare (AAW), vertical replenishment (VERTREP), search and rescue (SAR), troop transport and mine laying.

Cockpit and avionics systems
The helicopter has a crew of three: the pilot and Tacco (the tactical coordinator responsible for mission management) and the Senso (sensor systems operator) in the cabin. The cabin of the NFH is equipped with an avionics bay with a sensor operator station and a tactical coordinator station, a dipping sonar and a sonobuoy launcher.
The NH90 has 'fly-by-wire' all electric flight controls from Goodrich Actuation Systems and Liebherr Aerospace. This full authority quadruplex system increases the manoeuvrability of the aircraft while decreasing the weight. The avionics system is supplied by Thales Avionics and is based on a dual MIL-STD-1553B digital databus.
The cockpit has five 8in×8in colour multifunction liquid crystal displays for flight, mission systems and maintenance data. Honeywell Primus 701A weather radar is fitted.
The avionics package includes the Thales Topowl helmet-mounted sight and display which has a 40° field of view. Topowl also equips the Tiger and Rooivalk attack helicopters.
Under a contract awarded in January 2008, German NH90 helicopters are fitted with EADS Defence Electronics MilOWS, a military version of the HELLAS laser-based helicopter obstacle warning system.
The Nato frigate helicopter can be armed with anti-submarine torpedoes, air-to-surface missiles and air-to-air missiles.
The helicopters for France, Germany, Italy, Portugal and Finland are fitted with a self-protection suite from EADS Defence Electronics, which is also being supplied to the Tiger helicopter. The suite includes EADS AN/AAR-60 MILDS missile approach warning system, Thales TWE threat warning equipment with integrated radar warning and laser warning receivers and MBDA Saphir-M chaff and flare dispenser.
Norwegian NFH are to have the ITT AN/ALQ-211 integrated radio frequency countermeasures (IRFCM) suite. Swedish helicopters are equipped with an EW suite supplied by Saab Avionics, in conjunction with Avitronics of South Africa. Avitronics is jointly owned by Saab and Grintek.
The NFH is equipped with a tactical forward-looking infrared (FLIR) system mounted in the nose, a magnetic anomaly detector (MAD) and a sonar suite. French Navy NFH is fitted with the Flash Sonics sonar system from Thales Underwater Systems, which combines the Flash active dipping sonar with the TMS 2000 sonobuoy processing system.
The Norwegian and Swedish Navy NFH operate a version of the system, Flash-S, optimised for conditions in the Baltic Sea.
Dutch, Italian and German NFH are equipped with the helicopter long-range active sonar (HELRAS). The HELRAS dipping sonar is supplied by ELAC Nautik of Kiel, Germany, a subsidiary of L-3 Communications.
The NFH is equipped with a Thales European navy radar (ENR) 360° surveillance radar mounted under the nose. ENR is derived from Thales Ocean Master and has been developed in conjunction with EADS and Galileo Avionica. Swedish NFH has an AN/APS-143B(V)3 Ocean Eye multimode surveillance radar from US company, Telephonics. Ocean Eye has both SAR (synthetic aperture radar) and ISAR (inverse synthetic aperture radar) imaging modes.
The NH90 is equipped with an integrated communications and identification management system. The secure radio system provides air-to-air and air-to-ground communications. The TSC 2000 IFF (identification friend or foe) supplied by Thales was developed under German and French cooperation. The helicopter is equipped with a Link 11 secure datalink.
The NFH Helicopter is powered by two RTM 322-01/9 engines supplied by Rolls-Royce Turbomeca.
For the Italian requirement, GE Aircraft Engines and Avio are co-producing another engine model, the T700/T6E1. The engines are fitted with a FADEC system. This engine has also been selected by Spain.
In August 2007, a version of the RTM-322 for hot-and-high conditions was certificated by Rolls-Royce Turbomeca, for the helicopters for Oman.
The fuel tanks, which hold 1,900kg of fuel, are fitted with crash-resistant, self-sealing cells supplied by Uniroyal Englebert Reifen, based in Aachen, Germany.
The fuel management system is by AFG. The auxiliary power unit (APU), from the Microturbo division of the Labinal Group, provides electrical engine starting and powers the ground operation environmental control system (ECS).
NH90 orders and deliveries
In June 2000, the participating countries signed a contract for the production of 243 NH90s: France 27 NFH, Germany 80 TTH (with an option on a further 54), Italy 46 NFH and 70 TTH, and the Netherlands 20 NFH.
