there are no Yeshan designs in the junker; it's 100% Arashi.
the Yeshans built a lot of the ships we play in skirmish: the goldfish, pyramidion, galleon. these ships together make a incredibly dangerous battle-fleet: hard hitting heavy weapons with pyras punching holes in the enemies' battle line and causing openings for goldfish to exploit and chase down retreating ships and bring them down or disable them.
the Arashi built the junker, a reactive ship designed to survive the harsh Arashi sandstorms and defending the desert strongholds. we havn't seen their other ships except the fleets in skirmish, but I imagine that the Arashi are unusual in that they could actually have a infantry support of the airships. they are the only ones tough and resourceful enough to support infantry movement through the terrible deserts. the Yeshans are clever but rely on their huge dockyards and navy to move their armies around. the fleet we see in alliance (which you can play if you play if you preorder the game) has long range sniper ships and short range snub-nosed, tough, short combat ramming ships.
