Well Lionel was ahead of the US government. In 1960s Lionel made over a dozen Space, rocket and missile cars and engines with the Lionel name all over them.
You can drop their value and rename them for the new United States Space Force, Department of the Air Force if you want to "up date" them. I am sure Lionel and others will come out with re-labeled cars and engines for the new Space Force.
