Yes, choosing mechanical engineering first and then switching to aerospace engineering later is a well-advised and common route, especially if you’re still exploring your interests or aiming for broader job opportunities. Mechanical engineering is a foundational discipline that overlaps heavily with aerospace in areas like fluid mechanics, thermodynamics, material science, structural analysis, and control systems. Many of the core concepts taught in aerospace engineering are actually rooted in mechanical engineering.
One major advantage of starting with a mechanical degree is career flexibility. Mechanical engineers are in demand across many industries—automobile, manufacturing, energy, robotics, and even aerospace. This means that you have a wider safety net if you ever decide to explore industries outside aviation or space. After completing a B.Tech in Mechanical Engineering, you can then pursue a master’s degree or specialization in aerospace engineering. Prestigious institutes like IITs, IISc, and foreign universities offer M.Tech or MS programs in aerospace engineering for mechanical graduates.
In fact, many aerospace companies hire mechanical engineers for roles in design, propulsion systems, structural engineering, and thermal management, especially if they have done projects or internships in aerospace-related areas. This route is especially useful in India, where the number of seats in top aerospace engineering colleges is limited and competition is high. Choosing mechanical engineering from a good institute and building aerospace skills on the side—via electives, projects, internships, and research—can often yield better career outcomes.
So, if you're looking for a solid backup plan with exposure to aerospace, or you’re unable to get into a top aerospace engineering program right now, mechanical engineering is an excellent and strategic choice. It keeps your options open while still allowing you to move into the aerospace domain when you're ready.
