I've claimed two of them as bases to plunder all their goodness.
Does the one your in have a chevron mark?

If not try the P menu, maybe the core is set to public, I've found two SVs like that

There's a couple of different kinds that have cores in them already, including one that has an underground base beneath it, and the ones with the container controller and multiple extensions I think the core is somewhere in the middle of the extenders.

No.. No Chevron mark, and just containers, no container controllers. As far as I can tell hidden base. I will try digging underneath to find out.

The hidden base one has a switch on one of the cargo boxes that opens the trap door to the basement.

Not on my version it didn't..but one I knew it was there I just salvaged the trapdoor.
But my real problem is Base attacks. I survived the first and second 3 drone attack waves (1 rocket + 2 minigun) because I'd found a HV with a mini-gun turret.
Last night's attack of 3rocket drones+2 minigun drones, destroyed my HV. So now I have absolutely no means of defending the base. And that's the only mingun turret I've found.
Can't build them, can't build the improvised ones either (severe shortage of military salvage), and so far I've only found 2 useless SVs, so basically now dead in the water.

Look for "Junk Scout Vessel" wrecks....they are SV's with the graviton engine in them.....get this SV running and then use it to defend your base as well as to go further and find better SV's.

So lift and descent thrusters... exactly what are they as they do not appear in the tech tree, and of course the PDA as well.

From the Exploration Specialization Tree, you have the Graviton Drive there. These special drive and thrusters are more CPU friendly especially for the beginning. So looking for scout vessel is a good idea...

The ones with the container controller and extensions are easy to take out. Dig under and shoot the core that's in the floor

The frankly crushing waves of Drones when you have just started is something that's been observed here and we're experimenting with fixes.

So if any player shave found good work arounds or tactics would very very interested to hear of them!
