Major U.S. Naval Shipyards on the East Coast are located in which region?

The correct answer highlights that the major U.S. Naval Shipyards on the East Coast are located primarily in Portsmouth and Norfolk, Virginia. This is accurate because both Portsmouth and Norfolk host significant naval facilities and shipbuilding operations that are critical to the U.S. Navy's fleet maintenance and readiness.

Portsmouth Naval Shipyard is one of the oldest and most significant naval shipyards, focusing on the repair and maintenance of submarines. Norfolk is home to the largest naval base in the world, which serves as a vital hub for naval operations and logistics. The concentration of resources, workforce, and shipbuilding expertise in these areas solidifies their status as primary naval shipyards on the East Coast.

The other options include locations that do not accurately represent major shipyards exclusively on the East Coast or feature areas that are not recognized for naval shipbuilding or repairs to the same extent as Portsmouth and Norfolk. This distinction underscores the importance of the correct answer in terms of naval strategic operations and shipyard significance in supporting U.S. naval capabilities.
