German military kicks off heavy lift helicopter competition - source

BERLIN (Reuters) - Germany's top military official has approved plans to buy 45 to 60 new heavy-lift helicopters in a competition valued at nearly 4 billion euros that will be decided between the two largest U.S. weapons makers, a source familiar with the decision said.

General Volker Wieker signed a document that kicks off the long-awaited competition between Lockheed Martin Corp's CH-53K helicopter and Boeing Co's CH-47, but stressed that no decision had been made on a preferred helicopter model, the source told Reuters on Friday.
