The Power Behind the Guns, USS Wisconsin's 16-inch Projectiles

Some museum artifacts make you stop because of the history they represent. Others make you stop simply because of their size.

Among the newest additions to the Ghosts of the Battlefield collection are several 16-inch naval projectiles from the legendary battleship USS Wisconsin (BB-64). Standing beside one is an experience all its own. Photographs simply cannot convey their true scale. It is only when you see one in person that you begin to appreciate the incredible size, weight, and power of the weapons that once armed America's battleships.

These projectiles are far more than pieces of steel. They are tangible reminders of the sailors who loaded them, the gun crews who fired them, and the generations who served aboard one of America's most powerful battleships. Every mark, every pound of steel, and every inch of their massive construction tells part of a story that stretches across decades of American naval history.

The Iowa-class battleships, including the USS Wisconsin, carried nine 16-inch/50 caliber Mark 7 guns mounted in three enormous turrets. Among the largest and most powerful naval guns ever installed aboard a warship, they fired projectiles weighing between 1,900 and 2,700 pounds to targets more than twenty miles away. Armor-piercing projectiles were designed to penetrate heavily armored enemy ships, while high-capacity explosive rounds devastated shore defenses, artillery positions, and fortified enemy strongholds.

These massive guns served during World War II, the Korean War, and the Gulf War, providing long-range naval gunfire support long before precision-guided weapons became commonplace. Their fire protected amphibious landings, destroyed enemy positions, and supported American and allied troops ashore. For countless service members, the unmistakable thunder of battleship guns meant that powerful support had arrived.

Yet the true story is not only about the weapons. It is about the people who made them work.

Deep inside the heavily armored gun turrets, sailors operated with remarkable precision and teamwork. Every projectile had to be carefully moved into position, followed by multiple silk powder bags that propelled it from the barrel at nearly 1,700 miles per hour. Each gun could fire approximately two rounds per minute, with the tremendous recoil driving the barrel backward several feet before hydraulic systems returned it to battery for the next shot. It was an extraordinary combination of engineering and human skill, where every member of the gun crew depended on one another to perform their duties flawlessly.

Standing beside one of these projectiles today offers a new appreciation for that teamwork. It reminds us that behind every shell fired was a crew of young sailors whose training, discipline, and dedication made one of the world's most powerful naval weapon systems possible.

Of course, adding 16-inch projectiles to a museum collection also gives new meaning to the phrase "light lifting." Moving them is every bit as challenging as you might imagine.

We are deeply grateful to the crew and staff of the USS Wisconsin for helping preserve this important piece of naval history. Their generosity has made it possible for these remarkable artifacts to become part of the Ghosts of the Battlefield collection, where they will continue educating and inspiring visitors for generations to come.

Today, these projectiles no longer rest deep within the magazines of a battleship. Instead, they have found a new purpose.

Visitors who stand beside them quickly realize that they are seeing much more than ammunition. They are looking at artifacts that represent the service, sacrifice, and professionalism of the sailors who stood behind the guns. They are reminders of the engineering achievements that defined an era and of the men who carried out their mission wherever they were called.

At Ghosts of the Battlefield, our mission has never been simply to collect military artifacts. It is to preserve the stories they carry.

Every artifact has a story.

Every photograph carries a memory.

Every conversation helps keep history alive.

These 16-inch projectiles once projected American naval power across the world's oceans. Today, they serve a different purpose. They help ensure that the sailors who served aboard ships like the USS Wisconsin—and the generations who stood behind these extraordinary weapons—will never be forgotten.
