History

In 2003, the German Army Aviators Corps and the French General Delegation for Ordnance (DGA) issued the basic conditions for a new, heavy transport helicopter. This helicopter is to serve as successor to the German CH-53G/GSs, and the CH-47s of other European countries. In the spring of 2004 it became clear that there were no funds for development until 2015.

In February 2006, the German Federal Office for Military Technology and Procurement began discussing the HTH with Eurocopter.

In March 2006 Eurocopter announced that the HTH would be available at the earliest in the year 2018, if they could co-operate with another company and start the development by 2010. At the moment, it seems like the second partner is Sikorsky Aircraft, who already developed the CH-53K for the United States Navy.

Germany would like to procure between 60 and 120 helicopters, and another prospective customer is France, which then would get a capability which the French Army currently doesn't have. However the concept could also be suitable for other European countries.

Requirements

The European Heavy Lift Helicopter Program has issued a number of requirements to be met, including:

* Seven blade rotor with elastomeric head and high-performance composite blades
* Glass cockpit with four-axis autopilot and sensors for all-weather capability
* Fly-by-wire or fly-by-light
* Modular ballistic protection
* Full composite fuselage
* Reduced signature

The helicopter will be expected to carry the Dingo or Fennek armed personnel carrier, the French VBL and VAB (13,000 kg) vehicles, as well as Wolf and Wiesel (4,500 kg) or Bv 206.

Another wish is that the helicopter could use the same training equipment as the Tiger and NH90 helicopters.
