I've worked on government contracts, but not "bid" on them.
Apparently it is always 'better" to have some kind of underprivileged minority person as a majority owner in the company.
One subcontractor I worked with, the wife was a Native American, and a 51% owner of the small company... except I never met her, and the husband was the one clearly running the company. She was always absent at all company events.
Another project I was on was a joint venture between a large company, and an American Indian tribe. All the workers on the project were very much Caucasian, and while I wasn't in a position to work with the management, I never met a single one of the Native Americans.
