The funny thing is that NASA contracts the same companies as the military anyways (in the modern day, at least)

NASA Prime Contractors Aerojet Rocketdyne, Boeing, Jacobs, Lockheed Martin, and Northrop Grumman currently have over 3,800 suppliers contributing to Orion, the SLS rocket, and the lunar spaceport at Kennedy.

It gets slightly less funny when you realize that that's the reason Nasa's latest rocket made primarily from Space Shuttle parts is way more expensive than basically any commercial rocket. Essentially Congress only agrees to fund NASA if it means they also get to fund these military contractors.
