A Tudor warship, the flagship of Henry VIII's fleet, which sank in the Portsmouth Harbor, off the south coast of England, on its maiden voyage in 1545. The exploration, excavation, and recovery of the ship is the largest underwater archaeology project ever undertaken. By the time the ship was raised in October 1982, the project had already cost $4 million. The Mary Rose excavation has yielded remarkable information about Tudor military and daily life. It has also provided the opportunity for the development of new equipment and techniques for underwater archaeology.
