What rocket ships were at invasion of Normandy?

During the invasion of Normandy, commonly known as D-Day, there were no rocket ships involved in the operation. The Allied forces primarily utilized landing craft, transport ships, and naval vessels for the amphibious assault on June 6, 1944. While there were rocket systems used for bombardment, such as the British "Hedgehog" and American "Calliope" rocket launcher mounted on tanks, these were not classified as rocket ships. The focus was on delivering troops and equipment to the beaches rather than utilizing rocket-powered vessels.
