The airframe itself is stealthy, having the radar cross section of a large bird, and it is also less noisy for a helicopter. Combine it with a fire control radar and fire and forget radar equipped hellfire missiles and you have a platform that can fight quietly and is hard to detect at standoff ranges. It's real contribution though, is it's capability to send digital, real time information to commanders on the ground, airborne C3I platforms, and ostensibly control and view imagry from UAVs. It's being sold as the "quarterback for the Army's Objective Force". If it wasn't for that, it would probably already be dead as a program IMO. The AH-64D Longbow has some of the same packaging and continues to be upgraded but lacks the stealthy radar evading profile of the Comanche.
