Images are from the 2012 New Atlas article ORBITEC flight tests new vortex liquid fuel rocket engine. One looks a bit like a US military or DoD logo, one perhaps is ATK, but I'm not sure. Is this effort a joint research project between all of these organizations?
Related question: Are there any complications of the position of the oxidizer injector on Orbitec's vortex rocket engine?
