Some maritime careers begin with the machinery you can see. Nuclear engineering often begins with the systems and physics you cannot see directly: energy, heat transfer, radiation, reactor control and the engineering disciplines required to operate complex systems safely.

Nuclear engineers work across energy, research, defense and government. In the maritime world, the most direct connection is naval nuclear propulsion.

What does a nuclear engineer do?

Nuclear engineers research, design, analyze, or operate systems involving nuclear energy and radiation. The Bureau of Labor Statistics notes that their work can include reactor systems, safety, regulation, research, defense, and power generation.

The field is highly technical and safety-focused. Engineers work with physics, heat transfer, materials, instrumentation, controls, procedures, and rigorous documentation.

How does nuclear engineering connect to the Navy?

The U.S. Navy operates nuclear-powered submarines and aircraft carriers. Nuclear-trained officers and enlisted personnel support propulsion plants that must operate reliably for long periods under demanding conditions.

Civilian engineers also support naval nuclear programs through government laboratories, shipyards, engineering organizations, and defense contractors. Some roles focus on design and analysis; others focus on maintenance, testing, operations, or program management.

An important note about Battleship IOWA

Battleship IOWA is not nuclear-powered. The Iowa-class battleships use conventional steam propulsion, so visitors should not confuse IOWA's engineering plant with a naval reactor plant.

The connection is instead through systems thinking, energy, engineering discipline, safety, and the scale of technical responsibility required aboard major warships. A student fascinated by how a large ship produces and uses power may find nuclear engineering worth exploring even though IOWA itself is conventionally powered.

What education is usually required?

BLS says nuclear engineers typically need at least a bachelor's degree in nuclear engineering or a related engineering field. High school students interested in the field should build a strong foundation in algebra, trigonometry, calculus, chemistry, and physics.

Depending on the career, graduate education may be useful or required. The Navy has its own selection and training requirements for nuclear programs, which are separate from simply earning a college engineering degree.

What skills matter?

Precision matters. Nuclear work requires disciplined procedures, quantitative reasoning, careful documentation, and the ability to understand complex interacting systems. Communication is equally important because safety depends on teams sharing accurate information.

Students who enjoy difficult math and science problems, are comfortable being held to high standards, and want to understand energy at a deep technical level may find the field rewarding.

What kinds of careers are available?

Nuclear engineers work in power generation, research laboratories, federal agencies, engineering firms, defense organizations, and the military. BLS reported a 2024 median annual wage of $127,520 for nuclear engineers, while projecting a small overall employment decline through 2034 but continued replacement openings.

For students, the more important point is that nuclear engineering is a specialized field with multiple applications - not only commercial power plants.

Scholarship and service pathways

Students interested in civilian Department of Defense STEM careers may also encounter scholarship-for-service programs. The DoD SMART Scholarship supports eligible students in approved STEM disciplines, including nuclear engineering, naval architecture, ocean engineering, and other technical fields, in exchange for a civilian service commitment after graduation.

Programs change, so students should always review current eligibility rules and obligations directly with the sponsoring organization before applying.

What can you do now?

Take the most challenging math and physics courses you can handle successfully. Explore mechanical and electrical engineering as well as nuclear engineering. Learn how power plants convert heat into useful work. Visit universities with nuclear or energy programs and talk with students about the workload and career options.

If Navy nuclear service interests you, use official Navy recruiting and program information to understand the current requirements rather than relying on secondhand descriptions.
