Horatio Nelson in the modern Royal Navy

What role could Horatio Nelson serve if he were transferred to a modern Royal Navy ship?

His most plausible role would be public relations or historical testimony, while his wounds and obsolete professional context rule out immediate operational command.

Nelson's fame would survive the journey, while his eighteenth-century command experience would not give him an immediate place in a technologically and institutionally different service. The practical answer is a public-relations tour, using Nelson's name and story rather than placing him in operational command. Nelson's accumulated wounds could also lead directly to medical retirement and a pension. Jokes about historians questioning him underline a more serious point: his greatest modern value would be as a witness to his own era.
