Nuclear Submarine Officer

Also called: Navy 1120, Nuclear-trained officer

Officer who runs a nuclear reactor and leads sailors aboard a submarine on months-long silent patrols.

A day in the life

Submarine officers spend about a year in nuclear power school, then go to sea for patrols where there's no sunlight and little contact with home. They stand watch over the reactor, navigation, and weapons. Nuclear officers are recruited by power utilities and engineering firms at high salaries.

Training

Bachelor's degree (4-year), about 6 years after high school. Bachelor's (STEM strongly preferred, calculus and physics required), interview with Naval Reactors, then ~1.5 years of nuclear and submarine training. Nuclear bonuses can exceed $30k/year. Free-college benefits: Tuition Assistance (up to $4,500/yr) while serving, the Post-9/11 GI Bill (36 months of tuition + housing stipend) afterward, and SkillBridge internships before separating.

Ways in: Military, 4-year college. Training cost: Get paid while you train.

Majors to look at: Nuclear Engineering, Mechanical Engineering, Physics, Mathematics.

Outlook

Growing about average. Military specialties are not in BLS projections. The services recruit for this job every year and openings track force size and retention rather than market growth.

Will it last? Our AI estimate

Low risk for 10 years. Automation aids sonar and reactor monitoring; leading a crew on silent patrols stays human.
