The term "navy rum" comes from the rum that the Royal Navy ships kept on hand and rationed to sailors in the 1800s and 1900s. Navy rum is typically higher proof and a blend of aged rums from the Caribbean islands of Trinidad, Barbados, Jamaica, and Guyana. Fun fact - some pirates actually started off in the British Navy before starting a life of piracy, and developed their taste for the rum on those ships. That's one of the reasons why pirates are famous for drinking rum! Well, that, and the fact that they'd often take over Royal Navy ships and indulge in their rum.
