Representatives from Boeing and Sikorsky, two companies competing for a heavy transport helicopter contract awarded by the Bundeswehr, announced during the ILA Airshow in Berlin on April 26, 2018 that the official request for proposals from the Germany army would be reported to the end of 2018.

In order to replace its current fleet of CH-53G Sea Stallion, the Bundeswehr could acquire between 45 and 60 heavy lift helicopters. Including the cost of the maintenance, that contract could represent up to €4 billion.

As ILA Berlin was approaching, both Boeing and Sikorsky revealed  partnerships they arranged with German companies. Sikorsky formed a partnership with Rheinmetall and MTU Aero Engines among others. Boeing bonded with no less than ten German companies. The latter announced its last partnership on April 25, 2018, the opening day of the salon, with Rohde & Schwarz, a German airborne radio manufacturer. The two competitors presented their full industrial teams during ILA Berlin.

Even though the request for proposals was reported for undisclosed reasons, the procurement schedule could remain unaffected: The Bundeswehr will award the contract to the winner by 2020 and deliveries are expected by 2023
