004, I think the point SAS was making was that the FVL ( and FARA ) speed requirement puts them way out in front of the logistical support helicopters that provide the necessary logistical support for combat. I.e., air assault vs a special ops mission.
One other thing that has me puzzled is a subject I’m a rank amateur at: to whatever standards were set up, the Army tested the Comanche re radar and IR detectability and as far as I know, it passed. Comanche main rotor is oriented edge on looking forward. Now the tilt rotor 280 has its blades ( propellers ) oriented with flat areas lookiing forward. Then again so does the V-22 so does radar cross section not matter?
But then again, Bell initially presented a smaller FARA sized tilt rotor idea, but since have reverted to the Comanche look-alike Invictus. Curious.
