I have designed a number of things on the F-16 in 1990 and sold it to Loral.
The biggest was the 26 different power supplies in the 56M radar warning system. $4.6M for the engineering of which I got very little as I was an employee of a subcontractor.
I made multi output forward converters with FET linear post regulators.

I sold the same post regulator idea again to Spectrian that was building cell towers in China in the 1990s. I was an independent consultant then.
