The Mary Rose was named after Henry's younger sister, Mary, and the Tudor symbol, the Rose.

She was a new type of ship, specially built as a warship. She was armed with heavy bronze and iron guns.

Because she was built with the new watertight gunports, she could carry more heavy guns low down in her hull. This helped keep her stable.

In Henry's time, ships like the Mary Rose were hi-tech weapon systems. They were as powerful and modern as an aircraft carrier is today.
