Application timeline

The Lockheed Martin internship hiring cycle follows a predictable annual pattern:

August-October — Postings open for summer internships. Lockheed Martin recruiters attend fall career fairs at target universities. This is the best window to apply — most positions fill during this period.

October-December — First round of interviews and offers. Strong candidates with prior internship experience, relevant projects, or active clearances often receive offers before winter break.

January-February — Second wave of hiring for remaining positions. Some new openings appear as budgets finalize. Applications for Summer and Fall 2026 Pathways-style positions opened February 23-27, 2026 on lockheedmartinjobs.com.

March-April — Final hiring push. Fewer positions remain, and competition is higher for remaining slots. Last-chance window for students who did not apply in fall.

May-August — Summer internship period. Most interns work 12-14 weeks from late May through mid-August.

The total number of Lockheed Martin summer interns exceeds 3,000 annually across all disciplines, with mechanical engineering being one of the top three most common fields alongside electrical engineering and software engineering.

Conversion to full-time

This is the real value of a Lockheed Martin internship. The company uses its internship program as its primary pipeline for entry-level engineering hires. Approximately 70% of interns who complete the program and receive a return offer accept it — and Lockheed Martin aims to extend return offers to the majority of high-performing interns.

The conversion process works as follows:

1. Mid-internship review — Your manager provides formal feedback at the halfway point. This is your signal for how the return offer conversation will go.
2. Final presentation — Most business areas require interns to present their project work to a panel of engineers and managers. The quality of this presentation directly impacts the return offer decision.
3. Return offer — High-performing interns receive a full-time offer for an E1 (entry-level engineer) position, typically in the same group or business area. Offers are usually extended within 2-4 weeks of the internship ending.
4. Start date flexibility — If you have another year or more of school remaining, the offer is held open with a deferred start date. Lockheed Martin will often invite you back for another internship in the interim.

E1 mechanical engineers at Lockheed Martin start at $69,500-$83,000 depending on location and degree level (BS vs. MS). Having a completed internship with a return offer typically places you at the higher end of the E1 band.

Interview preparation

The Lockheed Martin internship interview process typically includes one or two rounds:

Phone/video screen (30-45 minutes): A recruiter or hiring manager asks about your background, interest in aerospace, and relevant coursework or projects. Common questions include:

• Walk me through a design project you worked on and the engineering trade-offs you made
• Describe a time you worked on a team project and dealt with a disagreement about the technical approach
• What interests you about working on defense and space programs?
• Are you comfortable obtaining a security clearance? (The only acceptable answer is yes)

Technical interview (45-60 minutes): For more competitive positions, a second interview with engineers from the hiring team covers technical depth. Expect questions on:

• Stress analysis fundamentals (Mohr's circle, fatigue, fracture mechanics basics)
• CAD and FEA experience (specific tools and project examples)
• Materials selection trade-offs (aluminum vs. titanium vs. composites for a given application)
• Thermodynamics and heat transfer concepts relevant to aerospace thermal management

You do not need to ace every technical question — interviewers are evaluating your problem-solving approach and ability to communicate engineering reasoning, not just final answers. Showing your thought process clearly matters more than getting the exact number.

Tips for a strong internship

Volunteer for extra work. If your primary project has downtime, ask your manager or adjacent teams if they need help. Exposure to multiple projects demonstrates initiative and gives you more material for your final presentation.

Learn the tools. Get proficient in whatever CAD and analysis tools your team uses. A summer is enough time to go from basic familiarity to productive competence in CATIA or ANSYS. Your manager will notice.

Build relationships. The intern cohort is your future professional network. The engineers you work with may be your references or even your future managers. Attend every intern event, ask questions in meetings, and follow up with people whose work interests you.

Document everything. Keep a detailed engineering notebook or digital log of your work. This helps with your final presentation and provides concrete examples for future job interviews.

Ask about the return offer early. During your mid-internship review, ask directly what you need to do to receive a return offer. This shows confidence and gives you actionable feedback for the second half of the internship.
