Lockheed Martin Internships: Clearance, Citizenship, and 2027 Roles

Lockheed Martin internships for 2027 are posted one requisition at a time, and each one sets its own clearance and citizenship rules. On November 12, 2026, Intern Insider listed about 160 open Lockheed Martin internships, and about 90 of them had been added in the past week. This guide shows where those roles sit inside the company, how to read the clearance fields on each posting, and eleven live roles with the lines that decide who can apply.

If you are comparing defense employers, our Northrop Grumman internships guide walks through that company's open listings. This guide takes a different route. It reads Lockheed Martin postings one at a time, because the clearance and citizenship lines change from one requisition to the next.

Where Lockheed Martin internships are open#

Lockheed Martin intern postings name the business area that owns each role. On November 12, 2026, Space had the most open internship listings with 63. Rotary and Mission Systems, which includes Sikorsky in Stratford, Connecticut, had 48. Aeronautics had 24, and Missiles and Fire Control had 19. The last five sat in smaller units, including two at Lockheed Martin Canada CDL Systems in Calgary.

The sites follow the business areas. Space roles cluster in Littleton and Highlands Ranch, Colorado, King of Prussia, Pennsylvania, and Sunnyvale, California. Rotary and Mission Systems roles sit in Uniondale and Liverpool, New York, Moorestown and Mount Laurel, New Jersey, and Stratford. Aeronautics hires in Fort Worth, Texas, Palmdale, California, and Marietta, Georgia. Missiles and Fire Control hires in Orlando, Florida, Grand Prairie, Texas, and Camden, Arkansas, and Orlando has Rotary and Mission Systems roles too. You can see every open role by city on the Lockheed Martin company page, and the Summer 2027 roles on their own Summer 2027 page.

Most open roles are technical. On November 12, 2026, 43 of the 159 listing titles included the word software and 26 included systems, and another 29 were broad College Student - Technical postings. Supply chain, finance, procurement, proposals, and business analyst internships were open too, in much smaller numbers.

How to read the clearance fields#

Every Lockheed Martin requisition ends with a short block of fields. Two of them matter most for students. Clearance Prior to Start tells you what has to be in place before your first day. Final Clearance tells you what the role needs once you are working.

The Clearance Prior to Start field was less strict. On the same day, 103 of the 159 postings showed None before the start date, 52 showed Interim Secret, three showed Secret, and one showed TS/SCI.

Do not treat a Final Clearance of None as a sign that anyone can apply. The Aeronautical Engineer Intern posting in Palmdale lists None for both clearance fields and still says "Must be a US citizen." The GN&C Engineer Intern posting lists None for both and includes "Must be a US Citizen" in its basic qualifications. The Finance Intern posting lists None but asks for the "Ability to obtain and maintain a clearance." Read the basic qualifications as well as the fields.

Eleven open Lockheed Martin roles#

These postings were read on Lockheed Martin's career site on November 12, 2026. They cover all four business areas, a business track, and the two Calgary roles.

Canadian roles in Calgary#

The two Canadian postings are with Lockheed Martin Canada CDL Systems, which builds ground control software for uncrewed vehicles. Both describe "a 16-month internship position available engineering students who have completed their third year," which fits a Canadian co-op sequence more than a summer term.

• Technical Co-op I: Software Development Intern. The work is "primarily in C++" with test-driven development, and the posting names Software, Computer, Geomatics, and Electrical Engineering, along with Computer Science, as fitting programs.

• System Engineering Intern. The intern helps capture product requirements for Skunk Works Canada development. The posting asks that you be "Eligible for Canadian Controlled Goods clearance."

Neither Calgary posting shows a pay range.

Pay on Lockheed Martin intern postings#

Lockheed Martin sets intern pay by location. The Business Analyst- Intern posting spells out four zones. Zone 1, which includes Sunnyvale and the New York City area, shows $25.18 - $35.19. Zone 2, which includes Denver, King of Prussia, Stratford, and Moorestown, shows $22.66 - $31.67. Zone 3, which includes Dallas and Fort Worth, Orlando, Grand Prairie, and Marietta, shows $20.14 - $28.15. Zone 4, which includes Camden, Lexington, and Lufkin, shows $18.31 - $25.59.

The postings label these as a full-time salary range without a pay period. Some roles use their own range, such as the GN&C and Proposals roles above, so check the posting itself before you compare offers.

How to apply#

Apply on Lockheed Martin's career site from the listing link. A few habits help.

• Apply to the requisition that matches your class year and degree. The basic qualifications are specific, and the Cybersecurity Intern posting is not the only one that names a class year.

• Check both clearance fields and the basic qualifications before you apply, and keep your citizenship documents ready if a posting asks for them.

• If you are a Canadian student, look at the Calgary roles and plan for a 16-month term.

• Apply early. About 90 Lockheed Martin internships were added in a single week before November 12, 2026, and the postings we read show no closing date.
