The red ship and the green ship, as well as the Dark Angels Imperial Cruiser, are from the mod called
Moar Ships. There's also
Endless Cargoships, which adds some other space craft to the mix.
How I currently capture them: I fly to them with just my jetpack if they get within about six thousand or five thousand metres, getting myself up to max speed then turning off my jetpack and inertial dampeners to save energy for grinding and torching, but I stop at about a thousand metres away from it to see if I can spot automated turrets.
If there aren't any turrets, I simply fly in and look for the entrance doors or roosterpit windows to cut my way to the controls, then fly the ship to my base.
If there are turrets, I try to quickly fly around at a safe distance to see if there are any blind spot angles where I can approach from. If there don't seem to be any safe angles, I start to run low on energy, and/or the ship is getting close to the edge of the beacon range of my base, then I fly back to base. But if there are safe angles, I go in and try to get to the roosterpit as quickly and safely as possible so I can make runs to recharge my suit while still on the ship, also to turn on the inertial dampeners to get the ship to stop. I then look for the reactors so I can get all the turrets to shut off, then I get outside and grind them all down to incomplete states. I've had problems where captured ship turrets will attack my stuff even after I've taken control of them and changed their ownership to me.
