Which Is the Best Between Aerospace Engineering And Mechanical Engineering?

These two career paths have advantages and disadvantages, but it all depends on your interest.

However, in my candid opinion on this matter, let’s look at something I agree with.

According to Quora, Hosea Siu, [PhD Aeronautics and Astronautics, Massachusetts Institute of Technology] commented;

“While I think the general advice about a bachelor’s in mechanical engineering being more broadly applicable is correct most of the time, I also think it depends on the school.

I had the same thoughts about aerospace/mechanical going into college and tried out an introductory aerospace class to see how true it was. Turns out that while the stereotype of “aerospace engineering is just high-speed, variable-pressure, safety-critical mechanical engineering” is true (and why aerospace is a subset of mechanical in a large number of universities), there are also some universities where the aerospace department embraces what I would say is a different approach to the engineering curriculum than the mechanical department.

For example, at MIT (where I remember one of the heads of eduation in the aerospace department specifically saying “we fight to justify our existence in light of great departments in mechanical engineering and EECS and have for as long as we’ve existed”), there is a much greater emphasis on things that are critical to aerospace systems, but not covered much by other departments.

Things like systems engineering (especially systems engineering), human factors, mission architectures, real-time software, etc. Yes, the basic engineering classes that most undergraduates take to begin with overlap heavily with what our mechanical engineering counterparts deal with, but the approach to these classes, as well as the opportunities for more specific classes in the areas above (and things like flight vehicle dynamics, space propulsion, turbomachinery, etc that could, in theory, fall under mechanical engineering, but fit much better under aerospace), are what differentiate the departments.

The general feeling that I’ve gotten is that the mechanical engineering department here teaches its students how to design and build great products*, while the aerospace department teaches its students how to specify and fulfil mission requirements. The difference, in some ways, comes down to attitude, in addition to the specific skills you’re taught.

Some aerospace departments out there take that approach, or something similar, in which case you should consider that when choosing which major to do. Others might not be as differentiated from the older discipline of mechanical engineering other than by being more specific, in which case you might, in fact, be better served going into something like that given a legitimate concern of being pigeonholed.

*I’ve heard some less charitable members of the aerospace community describe this as “building widgets.” I’d be a little more careful about appropriately acknowledging our academic forebears”.

So, you can see that it all depends on you.


Is aerospace engineering or mechanical engineering better?

No. They are both good engineering careers which are fulfiling and financially rewarding. Aerospace Engineers are more likely than Mechanical Engineers to work for the military or the government. Mechanical Engineering has a broader scope in terms of employment. Mechanical and Aerospace Engineers both earn a good living.

Is aerospace engineering harder than mechanical?

No. Mechanical engineering is not hard but it carries a level of difficulty. Aerospace engineering is not more difficult than mechanical engineering because they both require similar skills.

Can a mechanical engineer become a aerospace engineer?

You can easily qualify for a graduate program in aerospace engineering or astronautical engineering if you have a solid foundation in mechanical engineering principles. Today, few pure aerospace or astronautical engineers are working in the field, but this is changing.

Is it difficult to find work in aerospace engineering?

Because aerospace engineering is very demanding, you may not find work immediately. However, a related job, such as that of an aerospace technician, can help you gain industry experience and contacts. You may be qualified for an aerospace engineering position after gaining valuable experience.


Everything that exists was built from something. Every technological advancement is hidden in the errors of the past. Hence, the need to keep striving and pushing ahead.

Whether you’re building, designing or supervising production, you play an important role in national and international development.

So, if you choose to become an aerospace or a mechanical engineer, you’ll still make both impact and a lot of money.
