Musk’s tweet was put down to an excess of exuberance. For the foreseeable future, the closest that Space Force personnel will get to war fighting in space will be sitting at consoles controlling satellites and space-based weapons systems. No one is going to stride the bridge of the Starship Enterprise for a very long time.
But it seems that Musk was in earnest. Recently, according to Space.com, he was engaged in a “fireside chat” at a meeting of the Air Force Association’s Air War Symposium taking place in Orlando, Florida. He spoke at length on the need for rapid innovation so that the United States can stay ahead of its nearest rival, China, in dominating the high frontier of space.
