SirK,
Might be time to break out the "Nunn-McCurdy Popcorn" for the -53K. Think it triggers at 25% over-run, so we're not far off now. Big, big risk for the Germans if it happens, Sikorsky and the USMC will focus entirely on US activity and they will be left to feel like, I imagine, Canada buying Cyclones. An undoubtedly impressive aircraft, but at an absolutely eye-watering cost......
