Sorry, but then I recall shooting Nova from Jackdaw, of what I was pretty anxious - maybe I remember something wrong and it was Sunslayer.
But then: Spatial cannot mount these anymore. As well as Mjolnir, because both had enough firepower and ability to do so (checked some time ago in Singleplayer). And I remember for sure both were able to do that, as I even joked with Char in the past about mounting Nova or SNAC on spatial.
