The submarine museum next to the Pearl Harbor National Memorial is turning 45 and has refreshed its exhibits, good news for visitors and for families planning a day out in Hawaii.

• The museum reworked its galleries for the anniversary, adding new displays and screens to tell the story better.
• The focus has shifted from pure history to what the submarine force is doing now.
• New exhibits cover work at Pearl Harbor Naval Shipyard, Arctic missions, and unmanned underwater drones joining the fleet.
• Another section explains what it takes to qualify as a submariner.
• The site sits a short walk from the national memorial and offers discounted tickets for kids and military families.

Outlook: More of the updated exhibits open to the public now, with the historic submarine out front still the main draw.
