Attack submarine returns to Groton base

GROTON, Conn. (AP) — A nuclear-powered attack submarine is returning to the Navy base in Connecticut following a six-month deployment.

The USS New Hampshire is expected back at Naval Submarine Base New London on Thursday.

The submarine departed on March 13 to conduct security operations around Europe and Africa and traveled more than 31,000 miles over the course of the deployment.

The Virginia-class submarine was commissioned in 2008. It is commanded by Navy Cmdr. John McGunnigle, a Boston native.
