When we(US) buy a fighter jet do we get them at cost?

An F-22 costs $143m. Meh…

Does that include some profit taking for Lockheed Martin, et al?

Is it like we’re buying a new car, or is it like hiring a group of people to make it on a salaried basis? We supply the materials, and they work for us at a certain salary.

Let’s pretend that an older model of plane goes on sale to another country. We could make one for ourselves at $5 only including materials. We probably sell it to them for $15 right?

Or….If a piano maker wanted to have a piano in their house, and it costs $2400 for the materials, isn’t that how much the piano maker would spend? But that same piano might be sold to someone else for $10,000.
