Virginia class submarines are fast attack submarines of U.S army. They are nuclear-powered. They are specially produced and using for littoral and open-ocean missions. Main production idea Virginia Class is producing an alternative for expensive Seawolf class attack submarines. They are now using for replacing Los Angeles-class submarines.

Seawolf class submarine is another fast attack type of U.S army submarines. Their order history was an opening for new age on U.S army in the last years of Cold War. Their production continued still 1995 but the information that Cold War has finished also finished their production.

All submarines’ crew is a combination of volunteer army people and professionals. Any of the army men needs to enter lots of hard tests before working on submarines.

Today, armies’ man needs a 2 day course before entering submarine. First test is Valsalva maneuver. It’s a general exhalation test named by Antonio Maria Valsalva. Today if a man is not successful on Valsalva maneuver, it’s not meant man is rejected but mostly doctors didn’t accept them for further tests.

Second test is Pressure Test. In pressure test, there are lots of phases. But the main thing controlling is patient because little tests are giving a feel that test completely finished but a new little test is coming after a wait. Especially sound test in this period is very popular. Sound comes in some different ways in the water and it’s very hard to determine where they are coming or they are coming from far or close.
