The Final Order was defeated on Exegol, and the Resistance was victorious. Volunteer troops gathered from all over the galaxy will destroy the Dyston-class Star Destroyers deployed in the sky one after another. Rather than making the Jiston class unable to fly, the top priority was to destroy the axial laser in its abdomen.
The Dyston-class is a threat to the Resistance, as it is a Star Destroyer and can burn down planets on its own. A masterpiece of the Empire's Tarkin Initiative and Sith Eternals over the years, it is an extremely advanced weapon that can be operated quickly and at low cost by a small number of people.
I'm sure they want to destroy every single Resistance ship.
But is that really the case?
Can you destroy a planet for far less than the Death Star? In other words, the technology is of great scientific and technical value. I'm sure researchers across the galaxy will be intrigued.
If this heretical technology is repurposed for peaceful purposes, the possibilities are endless.
(In real life, it's like nuclear power generation)
In other words, if you steal that technology from a Sith Eternal, you can acquire that technology in a much shorter time. If you sell or lend your technology to some company, you can earn a huge amount of money.
That's why it would be such a waste to destroy every single one of them.
It is highly likely that the Resistance had captured the Jiston class that destroyed Kijimi.
This is something the Sith Eternals want to avoid. Not only did they lose to the Resistance at Exegol, but they also lost the technology they wanted to protect forever. The technology that they have perfected over many years of struggle is taken away from them. That must be frustrating.
The Death Star built by the Empire was a threat that terrorized the galaxy, but its products were used for peaceful purposes. This must be ironic for the Emperor.
(I don't talk nonsense)
(Thinking like the US military)
