I've worked on (unrelated to nuclear stuff) computer simulation projects for the Navy where they had standard, notional models of the battleship which had the same sort of general properties you'd expect a battleship to have, but wasn't based on the design of any real battleship, so they could share them with researchers to develop their codes on without having to worry about revealing classified details.

Wonder if this isn't something similar, if the DoE has some sort of "standardized notional warhead" design they can use to give to outside researchers without having to give every post-doc and grad-student a security clearance.

The author addresses this in the addendum after the article. Something like that already exists, and it isn't this.

> MACE (Modal Analysis Correlation Exercise) assembly, and was created by the UK Atomic Weapons Research Establishment in the 1990s to serve as a sort of a Utah Teapot of weapons structural modeling: a benign shape that could be used to test aspects of the code that would nonetheless tell you if the code would work for real weapons assemblies.

Do you actually mean battleship, or frigate, corvette, aircraft carrier, etc? Battleships in the sense of the Iowa class and similar haven't been a thing in the US Navy for a very long time, unless you were working on blast damage/effect simulations in the 1980s when Reagan reactivated them for a short time.

It seems likely that theoretical work would still be done on battleships, after we stopped using them in the real world.
