Because the government does not control the data rights for the F-35 program, the uniformed maintainers can’t access the technical data needed to do much of the maintenance work for the F-35. Nor can the government provide companies with access to that technical information. As a result, Lockheed Martin has an absolute monopoly on the lucrative sustainment contracts for the program.
the government effectively surrendered its responsibility to maintain the equipment purchased with taxpayer dollars to the contractors. The contractors had little incentive to design simple and easy-to-maintain weapons since their business model centered around long-term sustainment contracts for their products.
Sustainment contracts are quite lucrative. Pentagon officials awarded Lockheed Martin up to $6.6 billion in 2021 to support the F-35 fleet for two years, through 2023. These contracts will grow even larger as more aircraft are delivered.
Oh the intellectual property of the F 35 belongs to LMT not US government that funded the development of that property.
