Did you know April 11 is celebrated as Submarine Day?   In 2020, we salute the day as the 120^th anniversary of the United States’  purchase of  its first commissioned submarine in 1900, the USS Holland. The Philadelphia Evening Bulletin snapped this image at the Philadelphia Naval Shipyard’s memorial service highlighting the day in 1960.

You can hop on deck of a real submarine, the USS Becuna, docked at Philadelphia’s Independence Seaport Museum. Designated in 1986 as a National Historic Landmark for its service in WWII and part of the Independence Seaport Museum’s Historic Ship Zone since 1996, USS Becuna continues to be a popular tourist attraction for the city.

The Philadelphia Evening Bulletin captured this image as the Becuna was moved into Penn’s Landing Marina as a new tourist attraction on June 22, 1976.

The SCRC holds many other images of this historic submarine
