Northrop Grumman mechanical engineering internship in 2026: pay, projects, and how to land one
Northrop Grumman hires hundreds of mechanical engineering interns every summer across its defense, space, and aeronautics divisions. The 2026 summer internship program runs 10-12 weeks and places students on real programs — not make-work assignments. Mechanical engineering interns work on structural analysis, thermal management, propulsion components, and spacecraft mechanisms alongside full-time engineers who have been building hardware for decades.
The pay is competitive with other defense primes and scales based on your degree level, geographic location, and whether the role is classified as technical or administrative.
2026 intern pay rates
Northrop Grumman standardizes intern pay using three factors: anticipated graduation date, cost of labor for the geographic location, and whether the internship is technical or administrative.
| Degree Level | Technical Rate | Administrative Rate |
|---|---|---|
| Freshman/Sophomore | $20.50–$24.25/hr | $18.00–$22.00/hr |
| Junior/Senior (BS) | $24.00–$30.00/hr | $20.00–$24.25/hr |
| MS candidate | $28.00–$36.00/hr | $24.00–$30.00/hr |
| PhD candidate | $32.00–$46.75/hr | $28.00–$36.00/hr |
The median mechanical engineering intern earns $28.50 per hour according to Levels.fyi, which aligns with a junior or senior BS student at a mid-cost location. At 40 hours per week over 12 weeks, that translates to roughly $13,680 before taxes.
Location adjustments
Pay varies significantly by site. A mechanical engineering intern in Manhattan Beach, CA earns toward the top of the band ($30-$47/hr), while the same role in Huntsville, AL or Magna, UT pays closer to the lower end ($22-$28/hr). The adjustment roughly tracks local cost of living.
What mechanical engineering interns actually work on
Northrop Grumman assigns interns to real program work, not simulation exercises. Here are the typical project areas for mechanical engineering interns:
Structural analysis and design
Interns run FEA models in ANSYS or Nastran to validate structural components for aircraft, spacecraft, or missile defense systems. You might analyze load paths on a satellite bus structure, evaluate fatigue life on a landing gear assembly, or design brackets and mounting hardware for avionics boxes. Deliverables include stress reports that feed directly into program design reviews.
Thermal management
Thermal engineering interns model heat dissipation for electronics enclosures, design heat pipes and cold plates for satellite payloads, and run thermal-vacuum test predictions. Programs like the Space Development Agency's satellite constellations need thermal solutions that work in both launch vibration environments and on-orbit vacuum conditions.
Propulsion hardware
At facilities like Chandler, AZ and Magna, UT, mechanical engineering interns work on solid rocket motor manufacturing — including case fabrication, nozzle assembly, and propellant processing support. Interns at these sites often get hands-on manufacturing floor experience alongside analytical work.
Mechanisms and deployment systems
Spacecraft programs need deployable structures — solar arrays, antenna reflectors, and booms — that fold for launch and unfurl on orbit. Mechanical engineering interns at the Goleta, CA and Redondo Beach, CA sites work on deployment mechanism design, tolerance analysis, and mechanism life testing.
Test engineering
Many intern positions involve planning and executing environmental tests: vibration (MIL-STD-810), thermal cycling, shock, and electromagnetic compatibility. You will write test procedures, set up instrumentation, run tests, and analyze results. This is some of the most tangible work available — you see hardware shake on a vibration table and write the report that clears it for flight.

Application timeline and process
The 2026 summer internship application cycle follows a predictable schedule:
| Timeline | Milestone |
|---|---|
| September–October 2025 | Applications open, campus recruiting events |
| October–November 2025 | Career fairs at target universities |
| November–January | Phone screens and interviews |
| January–March 2026 | Offers extended |
| May–June 2026 | Program start dates |
| August 2026 | Program end, return offer decisions |
Applications opened in fall 2025, and most offers go out between January and March. If you are reading this in early 2026, some positions may still be available — Northrop Grumman backfills spots when candidates decline.
Interview format
Mechanical engineering intern interviews typically include:
- Recruiter phone screen (15-20 minutes) — academic background, location preference, graduation date
- Technical interview (30-45 minutes) — fundamentals of statics, dynamics, thermodynamics, materials science. Expect questions like "walk me through an FEA analysis you've done" or "how would you design a thermal solution for a 50W electronics box in vacuum?"
- Behavioral questions — teamwork scenarios, time management, interest in defense/space
What strengthens your application
- GPA above 3.2 (3.5+ for competitive sites like Redondo Beach)
- Prior internship or co-op at any engineering firm
- Hands-on project experience (Formula SAE, CubeSat, rocketry club)
- Proficiency in CATIA V5, NX, SolidWorks, or ANSYS
- U.S. citizenship (required for all positions due to ITAR and clearance requirements)
Path from intern to full-time
Northrop Grumman converts a strong majority of its interns to full-time hires. The path typically works like this:
- Summer performance — your manager evaluates technical contribution, initiative, and teamwork
- Return offer — extended in August, typically for a position starting after graduation
- Pathways program — new full-time hires from the intern program enter a 2-year rotational development track
- Clearance processing — begins after accepting the full-time offer if not already initiated
Starting salaries for full-time mechanical engineers with a BS degree range from $75,000 to $95,000 depending on location. MS graduates start $10,000-$15,000 higher. The intern experience effectively serves as a 10-week job interview — companies invest in interns they already know can do the work.
How Northrop Grumman compares to other defense internships
| Company | ME Intern Pay | Program Length | Housing Help | Notable Programs |
|---|---|---|---|---|
| Northrop Grumman | $22–$47/hr | 10-12 weeks | Stipend at most sites | B-21, GBSD, satellites |
| Lockheed Martin | $20–$42/hr | 10-12 weeks | Stipend at some sites | F-35, Orion, Trident |
| Raytheon (RTX) | $22–$38/hr | 10-12 weeks | Varies | Missiles, radar |
| Boeing | $20–$40/hr | 10-12 weeks | Relocation assist | Commercial + defense |
| L3Harris | $20–$36/hr | 10-12 weeks | Limited | Sensors, space payloads |
Northrop Grumman's top-end pay ($47/hr for PhD candidates at California sites) is among the highest in defense. The housing stipend, when available, is a meaningful differentiator for students relocating for the summer.
