Political disasters in naval administration

What were three major political disasters in naval history?

The Revolt of the Admirals, the removal of the Earl of Sandwich from naval office, and the Imperial Japanese Navy's political course during the 1930s.

The US Revolt of the Admirals is a case in which disagreement over service roles became a public political crisis. The Royal Navy faced serious disputes but usually contained them before they reached the same public rupture. The removal of the Earl of Sandwich from office was also a damaging disruption for the Royal Navy. The third example is the Imperial Japanese Navy's political trajectory through the 1930s, when institutional and national choices drove it toward a disastrous war. The cases operate at different scales, from appointments to inter-service conflict to an entire decade of policy. Naval effectiveness can be lost in government and administration long before a fleet enters battle.
