Carol doesn't have the piercing durability needed to survive SB. If we take feats and anti-feats at face value, IW Iron Man is more durable than both of them (Thor blunt force, Carol energy). So let's not.
She did completely ignore the artillery fire that rained down on the Avengers in EG and those shots were powerful enough to pierce straight through the Leviathan. Now are they powerful enough to pierce the hull of ships that tank orbital entry crashes? Most likely. I think it's good enough to say SB doesn't have the feat of cutting someone that durable.
I thought those were missiles. So explosive impacts, rather than straight up piercing the leviathan. I mean, the last time I saw a leviathan explode like that, it was Iron Man in Avengers 1. The Leviathan still had its plates on below, hence smaller explosion. And whatever was next to that leviathan on the very left exploded too. But it exploded on immediate contact. I'd say they'd be powerful enough to blow up the Outrider ships because of the explosion upon contact, because those missiles aren't going very fast.
And Valkyrie's sword (not Dragonfang, because that got lost in Ragnarok) cut through a Leviathan easily. Considering that there's really no way her sword could be unique from the rest of them in New Asgard's armory, I think it's pretty telling. I wouldn't scale SB below that, since the Outrider ship feat is still there.
If those were explosions, Wanda would surely be dead. They're just really large bolts/bullets that deliver a lot of impact force. Watch everything that's not the Leviathan exploding and you'll see no real explosions. Who knows why the Leviathan exploded? Maybe the friction from hitting the armor plating at such high speeds or some chemicals inside the beast are combustible?
But hey, here's a video of a non-explosive armor piercing bullet that causes combustion anyway;
