A King George V-class battleship in 1904

What happens if a 1940s battleship is sent back to 1904?

A King George V would transform naval development through its machinery, power generation, aircraft, and other technologies that contemporary industry could eventually reproduce.

The decisive knowledge is distributed throughout the ship, from efficient machinery and electrical generation to scout aircraft and fire-control systems. Engineers in 1904 could inspect complete working systems rather than infer them from theory. Contemporary industry could work toward reproducing much of that technology. The resulting acceleration in Royal Navy and global development would matter far more than the combat power of one hull.
