[need help] How to retire salvaged/repaired civilian ship with hi-tech?

[Amoebanzai]

Once the pirate lair overwatching a alien ship graveyard was defeated, I immediately sent a construction ship to repair those alien ship with hi-tech components hoping to gain new techs, as what I was told in the popup message when I first discovered those ship.

Unfortunately, once the ship was claimed and later totally operational, there is simply no option to retire the ship.

What would I gain by repairing those alien civilian ships?

While repairing them, you get some progress in each component tech you haven't researched yet, that the ships are equipped with. There is also a small chance to get a "breakthrough" in the next tech of a research field that you are technologically behind, compared to the ship.

Once you are done repairing the ship, you now have a pretty strong ship, that is likely much stronger than anything you can make or will be able to make for a while. I suggest you keep it. Personally, I like to put any such ships in fleets that carry the same HyperDrive tech as them (so they all jump and travel together). They can be significant force multipliers in battles.

Disassembling it would be a waste I think, but if you really want to, you can Click the "Retire at nearest shipyard". The process of gaining tech advantages is the same as what I described for repairing the ship, except the progress boost and the chance for breakthroughs is higher.

You have a junkyard with civilian ships? Usually it's war ships....GP

You can retire only a functional ship. If it can move after the repair, you should be able to find the retire bottom or use the context menu to do so on a planet/space station. They are mostly without fuel, so after the repair they are slow. Colony ships of different races are a good way to get access to planets with other climates.

Constructor ships should learn to retire other ships and orbital objects, at least from the own fraction.

These alien ships are civilian ships. As I cannot retired a civilian ship built by myself. the salvaged alien civilian ship has not retire button.
