Complete dead-end technologically and politically, so this is basically just a gift to Lockheed. Lobbyist deserves a promotion!
The fuck do you mean dead-end? You think we'll just keep using chemical rockets until the end of time? Nuclear propulsion is the most efficient form of propulsion we have at the moment. Iirc, nuclear engines would dramatically cut down on travel time because you can burn for much, much longer due to their efficiency. The only reason we don't really use them is because everyone loses their shit and has a panic attack the moment you float the idea of putting a nuclear reactor in space (we still use RTGs though).
It's actually much much less dead-end than chemical rockets are. There's a lot of technological possibility for nuclear rockets, thanks to the energy density of nuclear power.
In theory you could even do fusion rockets in the far future, but we'd need to figure out fusion for that first.
But like, fusion rockets might be the holy grail for space travel, short of maybe antimatter rockets (but you can imagine the complications in that). This chain of technologies is absolutely something worth exploring.
