KITTERY (AP) – Escorted by a fireboat that sprayed plumes of water, the Navy’s newest submarine has arrived at Portsmouth Naval Shipyard in preparation for this week’s commissioning.

The New Hampshire, with a crew of 139 officers and enlisted personnel, was followed by a couple dozen fishing boats Sunday as it made its way to the submarine repair yard along the Piscataqua River.

Hundreds of spectators gathered in brisk, sunny weather at Prescott Park in Portsmouth, N.H., to watch the vessel’s arrival from the Navy’s New London submarine base. The submarine was built at General Dynamics’ Electric Boat division in Groton, Conn.

The commissioning of the New Hampshire, the fourth naval vessel to be named for that state, will be held Saturday.
