The Army has now started looking into what they want as a future heavy lift helicopter. Defiant could only lift half what the Valor lifted, and Sikorsky's president said X2 technology would not make a good heavy lift helicopter. So the Army has three choices. An upgraded Chinook, but the Army has seemed lukewarm to this idea. A Sikorsky CH-53K, but the CH53 series has never been able to displace the Boeing Chinook. Or a tiltrotor, if the Army wants speed and range. All of the big three will propose a tiltrotor if the Army requirement is for higher speed.
