One of the newest High Tech Aircraft Carriers of the Nimitz class is CNV-74
the USS STENNIS. This ship is a small self  supporting town at sea, with around 70 aircraft and 5000 crew members. With a flight deck of 1092 FT (333 Meters) 
and 257 Ft (78 Meters) and It's  height from keel to mast 244 FT (74 Meters)  equal to a 24 story building, it is a small floating air base with an speed of more than 30 knots. The ship has 4 catapults, so they can  launch  4 aircraft at  a  time, but this ship is also able to recover two aircraft and launch 2 aircraft at the same time.

During our visit the USS STENNIS was participating in operation Enduring Freedom and was responsible for the night opts, the planes were launching 
and recovering  between 22.00 and 14.00 hours.

On day time the missions ware flown from the carrier of the Nato country's, 
the Italian Navy had their aircraft carrier Gibaldie with the AV-8 and Choppers, France had their aircraft carrier  Charles de Gaulle  with the super Etandartd, E-2 and Choppers the UK had sent their aircraft carrier H.M.S. Illustrious 
with the Sea Harriers and Sea Kings. The support was given by assault ships of the US Marines with AV-8 and Choppers. They had flown  missions in Afghanistan also to support the US Marines.

The USS Theodore Roosevelt who was  around the Arabian sea in the beginning of Operation Enduring freedom was located in the Persian gulf.  It was there to support Northern Watch and Operation Enduring Freedom.
The USS Roosevelt and their  battle group had other targets to watch in the region, also they were  waiting for  the USS Kennedy who had relieved the USS Roosevelt of its duty in the Persian gulf. 

At the time we were visiting  the Carrier the planes of Carrier Air Wing 9
had to fly missions above Afghanistan to participate  in Operation Enduring Freedom. They had only three major targets left in Afghanistan to take care of. The other missions that the planes had  flown was in  support of ground troops and special forces around Kandahar, and CAP missions to defend their international battle group.
One of the reasons that there were so many Carriers in the Arabian sea was because it was not possible to fly the planes in over Iran.  The government of Iran had shut down the air space for planes that were involved with  Operation  Enduring Freedom. Also Saudi Arabia had forbidden to fly missions from  their country for Operation Enduring Freedom. Only Pakistan had opened some trails over their country to support Operation Enduring Freedom. They had opened some Air bases as escape bases for planes with trouble. Right now the USS Stennis is waiting on its relief, the operations in Afghanistan are almost  to an end. What the next mission is going to be is unsure at  this moment. 
But the area around Iraq is HOT, the US is building up Its activity's in the region.
