No, but crackpot inventors do. The charlatan tells people that he has invented a magic airplane technology. He the points to the US navy patent as 'proof' that such tech is possible. If his name is on the patent, all the better.

The US navy is a very large organization. I doubt this is a core program. This is some crazy think-tank operating way way outside oversight. Or it is an elaborate joke. Or an attempt to pad a resume before retirement. Or a "patent something or you're out" box ticking.
