From HAP to HAD: Future Tiger prepared to operate behind enemy’s lines

Tiger / Tigre HAD receives new weapons and improved self-defence system
13:12 GMT, June 5, 2009 The programme of the newest HAD version of the Eurocopter Tiger (company designation EC 665) is well under way, Major Sophie Le Berre, HAD TIGER Manager at French procurement agency DGA told defpro.com. The Tiger HAD (Hélicoptère d'Appui Destruction / Support Destruction Helicopter) has been ordered by the French Army, replacing previously ordered HAPs helicopters, as Le Berre said that the helicopter currently undergoes flight tests which are expected to end by 2010. After evaluation,
qualification and certification during 2011, deliveries may start in mid 2012, according to Le Berre.
Manufactured by Eurocopter in Germany, the Tiger which is called Tigre in France and Spain is a real all-terrain and all-weather helicopter. However, while designed during cold war times several adjustments have been required which lead to new specifications by the French Army in January 2003. With Spain joining the HAD programme in March 2004 and a contract signed between Eurocopter and OCCAR (Organisation Conjointe de Coopération en Matière d'Armement), a European organisation for armament cooperation in November 2005, the programme started and the very first HAD took off for its maiden flight in December 2007.
The HAD version of the TIGER is based on the TIGER HAP: The major difference between the two versions is the integrated air-to-ground missiles (AGM) capability. While France will convert 40 helicopters to the HAD version and equip each of them with eight Lockheed Martin Hellfire II air-to-ground missiles; Spain has chosen Rafael’s fiber-optic guided Spike-ER air-to-ground missiles, which are to be license-built by General
Dynamics Santa Barbara Sistemas for their 18 choppers. Both missiles are famous for their excellent accuracy and their high combat range of 8 kilometres. The Hellfire II missile will be launched in a semi-active laser guided mode through Lockheed Martin’s all-digital M299 "smart" missile launcher.
According to the DGA time-schedule, it is expected that airborne firing tests of the Hellfire will begin as of September 2009, while the Spike missiles has already been regularly tested for use on the HAD since April 2008. The Hellfire II however is already integrated and qualified with the Australian Armed Reconnaissance
Helicopter (ARH) Tiger, thus should proceed as expected.
The self-protection system, which is the same of the HAP, has laser and radar warning receivers as well as a missile launch detector. The entire systems information will be connected on a display in the cockpit and with the automatic chaff and flares dispenser. Fitted with this system and additional ballistic protection as well as armed with a Nexter 30mm cannon turret, the HAD is fully prepared to operate in hostile territory, Le Berre said.
With 6.6 tones, the Tiger HAD version will have a slightly higher take-off weight comparing to its predecessor, the HAP. To maintain the helicopters performance while dealing with higher weight, a new more powerful engine will be integrated in the aircraft. The MTR390-E (enhanced) engine built by MTRI – a joint venture
including Rolls-Royce, Turbomeca, MTU and ITP – will have a power increased by 14 per cent compared to the existing basic version, thus achieving nearly 1,500 hp. The engine recently performed ground tests and are intended to be implemented in the Tiger PS-0 Prototype very soon. According to a company spokesman, a first flight with the new engine on the HAD will be accomplished by summer 2009.
Further improvements of the HAD include an IFF interrogation function and as well as a laser designator incorporated in the Strix observation and sighting systems built by Sagem Défense Sécurité, part of
the French SAFRAN Group.
With high-performance optronic sensors, the STRIX gyro-stabilised system will provide the Tiger HAD with observation, identification and engagement capacities at long ranges both day and night, the company spokesman said. Through its dual-mode laser designator the new anti-tank weapons could be laser-guided and targets can be tracked simultaneously.
The Spanish HAD helicopters will be assembled in Eurocopter’s Spanish Albacete site, while the French will be assembled in the group’s main plant in Marignane.
“The HAD is the future Tigre, ” Le Berre said.
