From Gunner's Seat to Combat Action: A Look at the Bofors 40mm Anti-Aircraft Gun on USS Cassin Young

Описание: The most effective anti-aircraft gun system on the USS Cassin Young, the 40mm Bofors was one of the best medium-weight anti-aircraft systems of World War II. These guns were effective out to about 6 miles. During WWII, the Cassin Young carried ten guns in five twin-mount housings. The quad-housing currently on display Cassin Young was part of later modification.

The USS Cassin Young is a World War II Fletcher-Class Destroyer. Launched in September of 1943, the Cassin Young served with distinction in the Pacific theater including in the Battle of Leyte Gulf and the Battle of Okinawa. During her service, she was struck twice by Japanese kamikazes, which resulted in over 125 casualties.

After WW II, the Cassin Young was decommissioned, but was reactivated during the Korean War and continued in active service until 1960. She has served as a floating memorial at the Charlestown Navy Yard since 1981. The Navy Yard, also home to the USS Constitution (Old Ironsides) is a stop on Boston’s Freedom Trail.

This video is extracted from a video I created for Boston National Historical Park (National Park Service) for inclusion in a ranger-developed app/tour of the USS Cassin Young. The presentations is given by USS Cassin Young Volunteer Bob Harris.
