How do I get rid of this structure?

So... Randy did Randy-things and dropped this psychic surpressor guarded by SIX TURRETS on my map, when I was absolutely not ready for it.

It has already been there for 30 days, and is far enough away from my base to only be a minor inconvenience, but I can't set my colonists to handle or hunt, because of the enormous range of the turrets. It also applies a permanent debuff to all the women, and disables me from progressing in the Royalty, because the empire won't come as long as there are enemies on the map. Long story short, I really need to get rid of it.

I am around mid-game and already did a bunch of research, I have a bit of plasteel, components, a lot of steel, but no access to advanced components yet, so I don't have good armor.

I tried to brute-force it with some save-state-abusing, and went all in with 8 colonists multiple times, but it's no use, they get downed way too quickly.

My next idea was to research mortars for the first time, but I didn't know that reinforced barrels were a thing, so I never bought them.

I still think that mortars are my best chance, but the next friendly settlement is 5 days away, and might not even have reinforced barrels.

But it's Rimworld, there has to be another way to solve this problem, right?... help.
