Eurocopter’s Tiger HAD support and attack helicopter version for France performs its maiden flight

Marignane, France, December 17,
The first pre-serial Tiger HAD (fire support and destruction) for France made its maiden flight from Eurocopter’s Marignane, France facility. It marks an important step towards the Block I initial qualification of the Tiger HAD, which is one of four versions in Eurocopter’s multi-role Tiger combat helicopter family.

During the next several months, Eurocopter will conduct joint testing and development flights of this Tiger HAD along with the first Spanish Tiger HAD – which re-started its flight test sequences three months ago subsequently to its transfer to Spain and lay-up.

The Tiger HAD has a maximum takeoff weight of 6.6 metric tons, a more powerful MTR390 engine, an upgraded optical sighting system, an identification friend or foe (IFF) interrogator, improved ballistic protection and a new electronic warfare system.

On y parle bien d'IFF, mais plus précisement de "identification friend or foe (IFF) [b]interrogator[/b]". C'est peut-être la clé du mystère ?[/quote]
