This rating's uniform, also known as 'square rig', belonged to an Able Seaman and dates from the 1950s. This type of dress has not changed very much over the 20th century and so still looks largely the same today. Royal Navy ratings work on ships, submarines or on naval bases. They operate technology, carry out manouevres and do repairs. This sailor worked in the radar branch helping to locate enemy ships and aircraft. The Navy calls this uniform No.1 Dress which sailors keep for best. Sailors use No.3 Dress for working in.
