I was fascinated by this recent YouTube video, which discusses how the New Republic modified Star Destroyers to carry updated lasers, interdictor technology, and improved power plants.
Interdictor technology, according to the video, allows a ship to pull other ships out of hyperspace. Normal interdictor-equipped ships have half-spheres jutting out of their armor to store the needed machinery – but with the benefit of time and miniaturization, the New Republic was able to cram interdictor technology into the standard hull of a Star Destroyer, along with the needed power supplies.
There’s a lot of fascinating Star Wars lore in the video. If you’re a fan of Star Wars, watch the video! It’s at https://www.youtube.com/watch?v=ZwqFTpjfjq8 .
