Will Thoday, of Headlands, will complete 10 weeks submariner training with the Royal Navy, and could find himself at sea for up to six months working with cutting-edge sonar, fire control and tracking equipment. The 17-year-old, who is a former engineering student at Cambridge Regional College, is planning a long-term career in the Royal Navy. He said: Ive already done some training in a submarine, so I know quite a lot about what its going to be like. Ive also had a lot of land-based training including a trip to Bavaria where we went skiing. When I was at college, I was planning on an engineering apprenticeship but I talked to someone in the navy and found out about all the opportunities available. So I applied and was offered a place, which was fantastic.
