Answer 1

OP, could you link to whatever article you’ve found that said or implied that a nuclear rocket was designed or built?

Edit: It’s a gun. The rocket is the bullet, and the gunpowder is replaced by a nuke. There is still propellant involved, but it is ignited all at once with the nuke, and the resulting gasses are used to push the spacecraft.
