The Horizon V thing in particular is very nice IMO: it recalls me the marine shuttle thing in Alien2, because of the tail details...
It's an updated Horizont

Yup, I recognized it: one of my favorite shuttle design of all-time... I've always been very fond of Artmic works anyway: Megazone23, Gall Force serie, BubbleGum Crisis, AD Police,... are all into my personal Top25
