What is the location of MDSU-2?

The correct location of MDSU-2, or Mobile Diving and Salvage Unit 2, is indeed Little Creek, VA. This unit is part of the U.S. Navy's diving and salvage operations and is responsible for providing underwater capabilities and support to a variety of missions.

Little Creek has a strategic significance due to its proximity to the Atlantic Ocean and is well-equipped to support diving and salvage operations. In addition to training and operations, the location facilitates quick deployment to support various naval missions. The presence of MDSU-2 in Virginia supports a range of activities, including salvage operations, underwater repair, and the disposal of unexploded ordnance, which are critical in both peacetime and wartime scenarios.

The other choices represent significant naval locations but do not host MDSU-2. Coronado, CA is known for its Naval Amphibious Base and other units, Pearl Harbor, HI is a historic naval base, and Norfolk, VA houses the largest naval base in the world but is distinct from the specific operations of MDSU-2.
