Choosing between mechanical and electrical engineering for a Navy career involves understanding the roles available and the nature of work in each field. Both engineering disciplines offer valuable skills, but the Navy primarily focuses on operational roles rather than design and construction. Pursuing a degree through NROTC can lead to opportunities in various Navy specialties, including engineering duty officer positions, but most design work is done in the private sector through contractors. It's important to maintain strong academic performance in math and science while keeping options open for future specialization. Ultimately, the decision should align with personal interests and career goals, as the Navy provides diverse paths for engineers.
