How in the holy missile barrage?

So I'm returning to the game after about a year and just getting to grips with the new Metas and new toys that have been added in the past few updates, I played a game recently and I have no idea what we got hit by.

So long story short the opposing team were playing OSP, seems they had a carrier, and then 3 Monitor blobs all running plasma and 100mm single barrel turrets on remaining hard points. We got absolutely anhiliated. Was quite remarkable really. I got jumped in my Axford and promptly reduced to slag by two of the Monitor blobs. But then the two oxfords behind me also were vaporised by a stream. Like a literal river, of maybe x50+ S2 Non Hybrid missiles, there were two types mixed in together according to the Intel.

They were cruise guided as well, making turns around rocks and what not. I waited till the end of the fight to read the battle report to work out what was firing the missiles. And well, nothing had any missiles. No roll off launchers that I could see. The only thing the report showed carrying any kind of missile was the carrier. But it said it never fired any of them. I assume because Bomber loadouts don't show as fired by the carrier? But then how do bombers unleash a hell storm of cruise missiles like that??

The best bit was they repeated that trick at least 3 more times on the rest of our team.

I'm not sour, im actually rather impressed I just want to know how they did it, so I can try recreate it myself!
