PASCAGOULA, Miss. (AP) - The USS Mississippi, a sophisticated attack Navy submarine, is going into active service.

The 377-foot Virginia-class submarine arrived last month in Pascagoula and was commissioned Saturday. A commissioning places a ship into active service.

The Clarion-Ledger reports that the USS Mississippi, which cost $2 billion to build, was delivered a year ahead of schedule and under budget.

This is the fifth Navy ship or boat to carry the Mississippi name. It is expected to remain in the fleet for about three decades.

The submarine was christened at General Dynamics Electric Boat in Groton, Conn., on Dec. 3, and has been through sea trials. The submarine will be assigned to Submarine Group Two.
