Eurocopter, a unit of European aerospace and defence company EADS, expects to reach an agreement with the German government in about two to three months on a downsized order for helicopters, its chief executive said.

“We are in very constructive talks,” Lutz Bertling told journalists at the ILA Berlin Air Show on Wednesday.

German Defence Minister Thomas de Maziere wants to cut major defence orders as part of sweeping reforms of the military.

The army, for example, wants 40 instead of 80 of Eurocopter’s Tiger military helicopters and 80 instead of 122 units of the NH-90 transport helicopter.

Eurocopter is now trying to negotiate a deal in which the government orders about 15 naval versions of the NH-90, in addition to the 80 army models, Bertling said.

“We cannot imagine doing a deal without re-designation of some orders to naval helicopters,” he said, but added talks on the Tiger were currently going better than those on the NH-90.

Bertling’s comments were more upbeat than remarks made by parent company EADS’s CEO Tom Enders earlier this week.

He said at the opening press conference for the ILA air show that talks with the German government were “tough but constructive” and warned that involved companies might eventually have to think about utilising their capacities for other purposes, such as civil projects.

De Maziere’s plans also include cutting by 37 to 140 the order for Eurofigher aircraft and reducing an order for Puma tanks to 350 from 410.
