I agree! What people don't realize are the lucrative parts of a govt contract is the follow on contracts to support. You don't make money on the initial design of a plane, you make money on adding weapons and fixing bugs for the next 25+ years of the planes life. By having the development be a subscription, you also incentivize more continuous development and improvement of the product. For example, instead of designing the system, deploying it, and then have to negotiate a ton of PRs to fix the system after the fact, you can have a more continuous dev cycle, fixing the issues as they come up because you're on contract already to fix them.
