Now, does anyone know what field I could get in where I could work on Navy ships - like building them, repairs, all that kind of stuff? Or where I could learn about the engines they use and if there is even a demand for people who can work on these engines? I know welding is one area, but maybe there are others.
Shipyards use lots of trades - welders, pipefitters, electricians, engine mechanics, along with engineers, project managers, etc. For propulsion Navy ships use diesel engines, diesel-powered electric motors, gas turbines (jet engines), some steam, and nuclear propulsion (a field unto itself).
Best regards,
