We generally deployed the aircraft from C-5's. It's the fastest and quickest way, as less has to be torn down. The 160th has aircraft already configured for air transport, so when the ballon goes up, they just land a C-5, load, and leave.
We also would go by sea depending on the mission. The aricraft is broken down, shrink-wrapped, and loaded on cargo vessels, then reassembled on the other side. Takes more time, but you can also move alot of sircraft more efficiently.
We also took directly off aircraft carriers. The 1st Cav deployed to Vietnam off an aircraft carrier. The 101st deployed off a carrier for a Reforger back in the 70's. The 82nd flew off a Navy carrier in Haiti. The Kitty Hawk was avaialable for Army Aviation this time around for Afghanistan. 160th aircraft routinely operate off of seaborne platforms.
As a rule, Army aricraft don't deploy as easily as USN/USMC aircraft, because of design. They are primarily desgined to do what they do once they are there at the theater, not as regular, everyday use. It results in cheaper, lighter, and less complicated aircraft, but in recent years, it's been farily recognized that the Army needs more deployabble aircraft.
Originally the UH-60 and AH-64 were to be deployable in C-130, without any disassembly. That was the bill of goods sold to Congress, but the real world is always different, and that's not what we have.
