Appearing in front of a parliamentary committee in Berlin on Wednesday, Thomas de Meiziere is being asked to explain why development of a German drone – called a Euro Hawk – was not halted much earlier when it became clear such a device would not get clearance from aviation authorities.

The project – which has been scrapped – had cost 660 million euros ($860 million) before the plug was pulled on May 14. De Maiziere will also face questions from a budget committee on Wednesday.

Concerns that the Euro Hawk would not be approved by aviation authorities because it didn't have an anti-collision system caused the drone project to be abandoned. It was determined that adding such a system to the drones would have been cost prohibitive.

De Maiziere faces criticism for not coming to this conclusion about the expensive, tax-payer funded project sooner, and is seen to be fighting for his job at Wednesday's parliamentary inquiry.

Despite the drone debacle, de Maiziere said on Tuesday at a NATO meeting in Brussels that Germany would stick to its commitment to a NATO drone program that would see the alliance acquire five high-altitude unmanned Global Hawks as part of its Alliance Ground Surveillance (AGS).

The Euro Hawk is modelled after the Global Hawk intelligence-gathering drone, which is made in the US.
