Sikorsky and Boeing have formally responded to the German Air Force “Schwerer Transporthubschrauber” (STH) Program call for competition.  The STH  program, which will replace 45 to 60 helicopters, is valued at about EUR4 billion ($4.72 billion).  A contract award could be made in 2020, with deliveries to follow in 2023.
