Fisher's return as First Sea Lord was a political appointment

Why was John Fisher made First Sea Lord twice?

Because his political stature, name recognition, and press presence suited an unusually prominent naval appointment.

The panel answers the question primarily in political terms. Fisher possessed a name large enough to reassure or mobilize public and governmental opinion. The First Sea Lord's office also carried enough public visibility that press presence mattered alongside technical competence. The short answer does not claim that politics erased professional considerations, but makes Fisher's status the decisive reason for his return.
