An aerospace engineer designs, develops, and tests vehicles and systems that operate within Earth’s atmosphere and in outer space. That includes commercial airplanes, military helicopters, satellites, rockets, drones, and missiles. The median annual salary for aerospace engineers in the U.S. is $130,720, and the field spans everything from improving jet engine efficiency to designing spacecraft that can survive the heat of atmospheric reentry.
Two Branches of One Field
Aerospace engineering splits into two main branches. Aeronautical engineering focuses on aircraft that fly within Earth’s atmosphere: commercial jets, helicopters, and remotely piloted aircraft. The core challenges are atmospheric, like managing air resistance, optimizing lift and drag, handling turbulence, and selecting materials that stay strong under pressure while keeping weight low.
Astronautical engineering covers everything beyond the atmosphere: spacecraft, launch vehicles, and satellites. The problems shift dramatically once you leave Earth’s air behind. Engineers in this branch deal with microgravity, vacuum conditions, reentry heat, and propulsion systems that need to work in environments where conventional engines can’t. Many aerospace engineers work across both branches depending on their employer and project, which is why university programs typically teach the broader “aerospace” discipline rather than forcing students to choose early.
What Aerospace Engineers Actually Do
Day to day, aerospace engineers spend their time on a cycle of design, simulation, testing, and refinement. An entry-level engineer might start the morning reviewing design specifications, then spend several hours running computer simulations to check whether a component meets safety and performance standards. Afternoons often involve meetings with cross-disciplinary teams to discuss integration or testing progress, followed by refining CAD models and updating documentation.
At a higher level, aerospace engineers coordinate the full design-to-manufacturing pipeline. They assess whether proposed projects are technically and financially feasible, evaluate designs against engineering principles and environmental regulations, and inspect malfunctioning products to trace the source of a problem. The work is deeply collaborative. You might be working alongside structural analysts, propulsion specialists, avionics engineers, and software developers on a single project.
Specialization areas include aerodynamic fluid flow, structural design, guidance and navigation systems, instrumentation and communication, robotics, and propulsion. Some engineers focus on a single product type for years, whether that’s a next-generation commercial airliner or a satellite constellation.
Common Job Titles
Not every aerospace engineer carries that exact title. Graduates enter the field in a range of roles depending on their specialization:
- Propulsion engineer: develops and tests jet engines, rocket motors, and other thrust-generating systems
- Structural analyst: evaluates whether materials and design structures can withstand aerodynamic forces, using stress simulations and load testing
- Avionics engineer: designs and maintains the electronic systems for navigation, communication, and flight control
- Flight test engineer: coordinates test flights, monitors data collection during flight, and analyzes performance results
- Manufacturing engineer: supports production processes, troubleshoots manufacturing issues, and improves assembly efficiency
- Quality assurance engineer: runs manual and automated tests, investigates defects, and writes bug reports to ensure products work reliably before release
Education Requirements
A bachelor’s degree in aerospace engineering (or a closely related field like mechanical engineering) is the standard entry point. Programs typically require around 128 credit hours and take four years. The coursework is math-heavy and physics-intensive: expect multiple semesters of calculus, differential equations, and statistics alongside university physics and general chemistry.
Core engineering courses cover statics, dynamics, mechanics of materials, fluid mechanics, thermodynamics, and materials science. From there, the aerospace-specific curriculum adds aerodynamics, flight dynamics and control, aerospace structures, and orbital mechanics. Students also take courses in computer applications for engineering, learning the simulation and modeling software that dominates professional work. Most programs require a senior capstone design project where students work in teams to solve a realistic engineering problem from start to finish.
Internships and co-op experiences carry significant weight in hiring. Hands-on project work, whether through university labs, student satellite builds, or summer positions at aerospace companies, gives graduates a practical edge that coursework alone doesn’t provide.
Professional Licensure
Aerospace engineers can pursue a Professional Engineer (PE) license, though it isn’t universally required in the industry the way it is in civil engineering. The path involves earning a degree from an ABET-accredited program, passing the Fundamentals of Engineering (FE) exam (typically taken near graduation), accumulating four years of progressive work experience, and then passing the PE exam.
Only a licensed engineer can sign, seal, and submit engineering drawings. The license also opens doors to consulting, expert witness work, and starting your own engineering firm. Even in roles that don’t strictly require it, a PE license adds credibility and career mobility, which becomes increasingly valuable during industry downturns or when changing employers.
Skills That Matter Beyond the Degree
Technical competence is the baseline. You need strong foundations in math, physics, and the specific simulation tools your employer uses. But aerospace projects are too large and complex for any single person to execute alone, which makes several non-technical skills equally important.
Communication ranks high. NASA lists “superior communication” as a core skill they seek in employees, and private companies echo that priority. You’ll need to explain technical findings to teammates from different engineering disciplines, present results to project managers, and sometimes translate complex data for non-technical stakeholders. Closely tied to communication is collaboration: even university programs now structure major projects as team efforts, mirroring how the industry actually works.
Creative problem-solving is part of the job description, not a bonus. Aerospace engineers routinely face constraints that seem contradictory (lighter but stronger, faster but more fuel-efficient) and need to find solutions that don’t exist yet. Companies like Millennium Space Systems specifically recruit for employees who “solve problems creatively.” Leadership matters too, particularly on projects where a single error could waste years of work and millions of dollars.
Salary and Where the Jobs Are
The median aerospace engineer earns $130,720 per year according to May 2023 data from the Bureau of Labor Statistics. The pay range is wide: engineers at the 10th percentile earn around $81,620, while those at the 90th percentile bring in roughly $188,910. Experience, specialization, location, and security clearance status all influence where you land on that spectrum.
The largest employers fall into a few categories: defense contractors, commercial aviation manufacturers, government agencies (NASA, the Department of Defense, and the FAA), and a growing number of private space companies. The defense sector has historically employed the largest share of aerospace engineers, but commercial space is expanding rapidly.
A Growing Commercial Space Sector
The FAA forecasts that licensed launch and reentry operations will increase from a range of 174 to 183 in fiscal year 2025 to between 259 and 566 by fiscal year 2034. In the most optimistic scenario, that’s over 4,000 authorized space operations across the ten-year forecast period. The demand is being driven by satellite deployment and replacement, space tourism, cislunar operations (missions to and around the Moon), Mars exploration planning, and a newer category called in-orbit servicing, assembly, and manufacturing, where spacecraft are built or repaired in space rather than on the ground.
For aerospace engineers, this translates into growing demand for skills in reusable launch vehicle design, satellite systems, and the thermal and structural challenges unique to spacecraft that need to survive multiple missions. Commercial spaceflight now includes both government astronauts and private citizens, which means the industry is designing for a broader range of passengers and mission profiles than ever before.
