Sharky's list is pretty good. Except for the Chinook. Ugh. Worthless aircraft. And dangerous to boot. They are just the big brother to the Marines CH-46, which is being replaced by another worthless aircraft, the MV-22 Osprey. They look pretty neat though, I suppose.

I actually really wish the CH-54 Tarhe program hadn't been cancelled by the US Army. It is lonely being the only Heavy Lift Helicopter in the US military. While the 54 couldn't carry as big of a load as the 53, it could carry it right up to the belly, which made it much safer. Keeps the cargo from swinging around.

The Sikorsky UH-60 'Black Hawk' will always be my favorite helicopter. All of its versions. It is an extremely versatile aircraft and I hate that all the other armed forces get them and we don't. Even the Coast Guard has them!
I've gotten the privilege to work on them a little bit while deployed on a ship. The squids let me touch their precious Sea Hawk (SH-60) and help change a fuel line. It wasn't much, but I loved it.
