The Venator-class Star Destroyer was the Republic's primary aircraft carrier, deployed throughout the galaxy. It boasts reliable performance, commands air superiority, and protects the citizens of the Republic. It is a symbol of the power of democracy.
Even after becoming an Empire, Venators remained deployed in the skies.
In fact, it will increase.
Meanwhile, due to General Lampard's outrage, Tipoca City on Kamino is destroyed by Venator. The citizens are shocked by Venator's destructive power.
Isn't something other than Camino possible? It's certainly possible, just not.
This means that the Empire can now destroy any place it wants with Venator. The symbol of the power of democracy gives way to the symbol of the terror of an authoritarian state.
Ostensibly, it's about protecting citizens from fear. This will reduce the number of citizens who will oppose the empire. This is the long-term acquisition of air superiority. The Camino was just for show.
The Emperor also deploys Venators over Coruscant.
The purpose was to prevent surprise attacks during the war, but in reality, they were meant to intimidate.
Although he could destroy a city with a single finger, the Emperor was concerned that an officer would do it on his own like General Lampard. The dismissal of General Lampard was a warning to the Empire.
This is what happens when you disobey orders.
Command is left to the emperor alone.
If I run into trouble again after destroying another city, I'll do what Lampard did. (I didn't dissolve the Senate for times like this.)
