Virginia-class nuclear submarine

Rico says his friend Dave occasionally sends non-perv links, and this is a good one:

USS Virginia-class submarines are the United State's newest and most advanced submarine. The first Virginia slipped beneath the waves just eight years ago and only nine vessels have been completed. They take more than five years to build and run about $2.4 billion apiece.

The Virginia-class submarine is a new breed of high-tech, post-Cold War nuclear subs. The submarines are nearly four hundred feet long and have been in service since 2003. The ships were designed to function well in both deep sea and low-depth waters.
So far, nine have entered service. Cheryl McGuiness, the widow of one of the pilots killed on 9/11, christened the USS New Hampshire:

The USS Virginia's engines power a pump-jet propulsor rather than a conventional propeller. This design cuts back on corrosive damage and also makes the ship stealthier. The engine room, near the sub's stern, is the place where power from the SG9 nuclear reactor core drives the ship to nearly 32 mph when it's submerged.

The hallway extending from the engine room, over the reactor and through the living habitat in the center of the ship is dark so that sailors can sleep.

The ship has an airlock chamber with room for nine SEALs, who can exit the sub while its underwater by passing through a lock-out chamber in the center of the ship.

Submariners eat well the quality of the food is designed to offset the stress and burden of living underwater for months at a time. As one sailor said: "It's like having comfort food 24-hours a day."

The command center on the Virginia subs are much more spacious than previous submarines. The command center doesn't have to be directly under the deck of the ship in the Virginia-class subs because there isn't a periscope. This sub's "periscope" is a state-of-the-art photonics system, which enables real time imaging that more than one person can see at a time.

The Virginia eliminates the traditional helmsman, planesman, chief of the watch, and diving officer by combining them into two stations manned by two officers.
The Virginia subs carry a full crew of 134 sailors. Despite computer navigation systems all routes are plotted manually as well. The subs are equipped with a spherical sonar array that scans a full 360-degrees.

Down below the command center is the torpedo room, where it is possible to set up temporary bunks for special operations teams.

The ships carry up to twelve vertical-launch Tomahawk missiles and 38 torpedoes 

A petty officer on the USS Texas fires water through the torpedo tubes as part of a test. 

The subs were designed to host the now-defunct Advanced SEAL Delivery system, a midget submarine that transported Navy SEALs from the sub to their mission. 

The only thing in front of the torpedo room is the bow of the submarine, which contains sonar equipment and shielding designed to make the sub stealthier. 

Even as they are being built, new improvements and upgrades are being added.
