NASA does not have, nor want, nuclear weapons. But when it comes to a particular metric that is part of the Artemis Program to land people on the Moon, NASA guards a particular number like they are trying to prevent outsiders from cracking nuclear codes.

I am speaking of the number of Starship launches required to fuel a Starship-based lunar lander in low-Earth orbit such that it can fly out to the Moon, land there, and return to lunar orbit.
