In Star WarsStar Wars, Hyperspacehyperspace is the main way of travel. It's used by the rebel allianceRebel Alliance both as a way to attack and to escape.
Quite understandably, the empireEmpire created Interdictor Class destroyers-class Star Destroyers. Those starships where made with the sole purpose of preventing other starships to go into HyperSpacehyperspace.
But even though those ships existsexist, they barely saw any use at all, especially in battles where their presence would have changed the outcome of the war.
The most damning example that come to mind would be the battleBattle of Scarif. At that point, the Empire knew that a fatal weakness existed in the Death Star. So when the Rebels attacked Scarif, where the death star'sDeath Star's plan wherewas stored, it was pretty obvious what they were aiming for. So the empireEmpire sent a massive amount of reinforcementreinforcements, which lead to the rebels getting decimated. But a Corvette still manage to escape and enter hyperspace.
All the empireEmpire needed was one Interdictor, and the rebels would have never had a chance to win, because the plans would have never left Scarif.
Obviously, the easy answer would be that there was'ntwasn't any Interdictor available close enough to the battle to make it in time. Which would raise another question, why was such a vital ship, that can completely corner an enemy and cut off their only escape route, not a mandatory part of any and all fleets ?
Why were the Interdictor class-class ships, which provided an incredible tactical advantage, almost never used ?
