On page 16 of Battlefleet Koronus it is stated that Small Craft can be replenished through an acquisition test, however I cannot find the difficulty for that test nor any rarity for any of the type of small craft. Are these printed anywhere?

And on a similar note, are there any rarities mentioned for buying any of the vehicles provided in Into the Storm and Battlefleet Koronus?

If any of the above information is printed anywhere can someone give me a book and page number? Thanks in advance.

Into The Storm's vehicles all have rarities, listed with the rest of their stats. Note that it is hidden away in the "Special Rules" section, generally sandwiched between stuff like Reinforced Hull and Pilot Operated Weaponry
