It appears that in the Bin Ladin raid, the US has used a previously unseen stealth helicopter technology.

Stealthy helicopters are the holy grail but tremendously expensive. The biggest problem is that no matter what you do, you'll hear them coming, and the rotation of the blades causes radar returns.

The Comanche attack helicopter was an attempt at a stealthy attack helicopter, Boeing claimed that its radar return was 1/300th of an standard aircraft. But the project was expensive and it was gassed in 2004 with only two being built.





If you take a look at the rear rotor its shrouded. The picture of the tail section of the destroyed helicopter isn't shrouded so it would sound like a standard helicopter.
