The CEO of defense giant Lockheed Martin said Wednesday that the company is moving past a dispute with the Pentagon over a primer defect on its F-35 joint strike fighters and that the issue is “not a big show-stopper.”

The majority of the 200 or so F-35s with the production defect causing corrosion around fastener holes will be repaired within two years, Marillyn Hewson said during an investor conference.
