Marine archaeologists from Stockholm University and Södertörn University in Sweden made a remarkable discovery in the Blekinge archipelago.The remains of the sunken ship, Gripen, were found to be well-preserved, including two surviving cannon mounts and a unique weapons box.The weapons box contained bullet molds and a lead sheet, indicating it belonged to German mercenaries who sank with the Gripen.Researchers believe the findings will provide important insights into the development of military boats during the 'military revolution at sea.'
