The NHIndustries NH90 is a medium-weight multi-role utility two engine helicopter, developed in two main variants: TTH (Tactical Transport
Helicopter) and NFH (NATO Frigate Helicopter). The NH90 accommodates 2 pilots (and possible a sensor operator on NFH) and 20 troops or 12
stretchers with medics in its military role. The NH90 features a 4-bladed main rotor with blades made from composite materials and the hub
from titanium and a 4-bladed tail rotor assembly. The helicopter is powered by 2 Rolls-Royce/Turbomeca RRTM322-01/9, or two General Electric
/Fiat Avio T700/T6E1 turbo-shaft engines. The NH90-NFH variant is primarily designed for autonomous Anti-Submarine Warfare (ASW) and Anti
Surface Warfare (ASuW) missions. The comprehensive mission equipment packages allow a wide range of additional missions to be performed
including Search and Rescue (SAR), maritime patrol, vertical replenishment, troop transport, medical evacuation and amphibious support roles.
The helicopter is designed for day and night operations in adverse weather conditions from the decks of ships. Due to its weight and dimensions,
the deck-lock system, the deck traversing system and the automatic blade and tail folding system, it can operate from small frigates even in high
sea states. The NH90-TTH's primary role is that of tactical transport ie moving troops and supplies around. It can also be configured for more
specialist roles such as Combat Search and Rescue (CSAR). Up to 20 troops or 12 stretchers can be carried in the NH90-TTHs cabin. Small tactical
vehicles such Supacat ATMPs can be carried, with access via a hydraulic rear ramp. Up to 2500kg of cargo can be carried onboard.
In the early 1980s a European multinational development program was
initiated for a new multi-purpose transport and naval helicopter,
intended to replace the Bell UH-1 Huey, Aerospatiale Puma, Westland
Lynx, and Westland Sea King. In 1991, the project was known as the NH90
Europan Transport Helicopter. The program was formally initiated in
August 1992, with the establishment of the NHIndustries (NHI) for the
development and production of the NH90. Countries participating in the
project were France, Germany, Italy and the Netherlands. Norway became a
"risk-sharing partner" in 1994. Portugal joined the group on 21 June
2001. The NHIndustries consortium is headquartered in Aix-en-Provence in
France. Four Partner Companies sharing the Development, Production and
In Service Support of the NH90 Programme are: AgustaWestland (Italy)
32.00%, Eurocopter (France) 31.25% and Eurocopter Deutschland (Germany)
31.25% ( both belonging to EADS Group) and STORK Fokker Aerospace (The
Netherlands) 5.50%. On 1 September 1992, NH Industries signed a NH90 design-and-development
contract with NAHEMA (NATO Helicopter Management Agency). Design work on
the NH90 started in 1993, with the first three prototypes built in
Marignane in France. The first prototype: NH-90-TTH PT001 (F-ZWTH),
flew first on 18 December 1995; the second prototype NH-90-NFH PT002
(F-ZWTI), flew first on 19 March 1997 and the third prototype, NH-90 TTH
PT003 (F-ZWTJ) flew first on 27 November 1998. Prototype four NH-90
TTH PT004 was built in Gemany and flew first as 98+90 on 31 May
1999. Prototype five NH-90 NFH PT005 was built in Italy and flew
first as MMX-613 on 22 December 1999. The Industrialization and first
batch Production contract for 243 NH90 plus 55 options was signed on 30
June 2000 between NHIndustries and NAHEMA on behalf of the French,
German, Dutch, and Italian Ministries of Defense (MoD). Today, a total
of 529 firm orders have been placed by 18 armed forces in 13 countries,
including Australia, Belgium, Finland, France, Germany, Greece, Italy,
the Netherlands, New Zealand, Norway, Oman, Spain and Sweden.
On 30 June 2000, the Netherlands ordered 20 NH90 NFH's to replace the
Westland Lynx SH-14D
helicopters in service with the Marine Luchtvaartdienst. Changed needs
led to a revised requirement and the order was changed to 12
fully-equipped NH90 NFHs and eight NH90 TNFHs (Transport NATO Frigate
Helicopter). On 23 December 2009, the first NH90-NFH was handover to the
Netherlands military. This NH90-NFH was offered in a temporary MOC
(Meaningful Operational Capable) configuration. This means that not all
contractual specifications of the final version meets, but already can
be used for such education, training and coastguard duties. This
handover, which took place at AgustaWestland’s facility in Italy,
allowed the NH90-NFH-COM to undergo acceptance trials by military
personnel. On 17 May 2010, almost ten years after the order was placed,
the first Dutch NH90 was official handed over to the CLSK (Commando
Luchtstrijdkrachten) at Maritime Air Station De Kooy. The Royal
Netherlands Air Force' NH90-NFH N-228 (c/n 1228/NNLN08) was delivered on 26 July 2012.
This NH90 was in the (MOC) Meaningful Operational Capability configuration.
This NH90 will have to be upgraded in the future as it does not have the specification the original tender required.
The NH90 N-228 is based at Naval Air Station De Kooy, the military part of Den
Helder Airport, and joined 860 Squadron, part of the Defence Helicopter
Command (DHC). In September 2014, the Dutch government decided to suspend the
purchase of the last seven Dutch NH-90 helicopters of the order due to corrosion and abrasion noted on the thirteen NH-90 helicopters in
service. At the end of December 2014 the problems were classified and addressed and deliveries were resumed in 2015. On 17 February 2016, the
NHIndustries NH90-NFH N-228 of the Defence Helicopter Command (DHC) came in at the Heli Holland heliport near Emmen.
