I have conducted several surveys of a Valor-class wreck in system 'Cortez' after having an initial idea of salvaging ship weapon systems. Results you can see in attached file.
Basically, this husk has only one purpose - spewing large amounts of, what I suppose to be, methane-based gas into vacuum of space. Engines were damaged by large explosion, high probability that was NOVA torpedoes. Reactor is not salvageable and is polluting ship with increasing amount of gamma-radiation. Most of large-scale turrets were melted into structure by direct hits of a energy-based weaponry. There's huge chunks of exterior 'shell' missing and most important - almost every valuable piece of scrap was already snatched. I blame local junkers.
So, in general, there's nothing to do with that piece of junk. I don't even think we can scrap it for precious metals or something like that because of radiation leak. I am focusing back on something more practical and useful.
