Amphibious crafts

[P3D]

A small troop transport/amphibious ship, capable of delivering a company's (~2-300men) of troops to medium distances, usually below 2000nm, around Africa. The bunker capacity is mainly for fuel flexibility.
Fits in the smallest docks. Low stability is the usual SS2 bug thinking misc weight being high up.

I assume 400t of the misc weight is for troops and equipment capacity, the rest are cranes, boats and such.
