I really can't recommend this DLC, particularly with the current buggy state of the game as a whole.
So the ships are quite big, that much I will grant, but after the first hour or so, breaking them down begins to feel very stale, as you end up spending several hours just gathering bulk chunks of flooring and walls to hit targets of low alloy steel and iron that are far, far higher than anything outside of the DLC. For people who want to just shred a giant ship down to its base this is probably fine... but the game's buggy nature shines through the most in this DLC.
There are frequent issues with cables getting stuck floating in mid-air that simply cannot be removed which can block large crane-able objects which give large amounts of resources, which makes the process take longer and feel more frustrating. There are problems with the biggest ship where you can't remove parts of the ship with the crane due to them being blocked by other parts of the ship that need to be removed by crane... which can't be removed because of the first part, hitting you with a frustrating Catch-22. And sometimes if you're trying to knock down large amounts of wall and flooring by disconnecting them from the rest of the ship, gravity just fails to work and you have a giant chunk of the ship just floating in mid-air.
The rest of the game is buggy, sure, but the contracts are generous enough that you can still progress and make money without any real lost time. But with these large ships requiring mass amounts of resources, especially the final ship, it just detracts too badly from the experience to be ignored.
EDIT: The developers have improved on some of the bugginess mentioned. Now the hull issue I mentioned where the hull sections overlap conflictingly seems to be gone, and while the gravity still isn't perfect, it seems like you're far less likely to run into floating chunks of ship blocking you from craning away pieces of hull.
However, I'm still keeping this review as a negative because there are still noticeable bugs and fully completing the last ship, the Pobeda, is just exhausting. The requirements for the first contract are obscenely high for the amount of money you get back.
