They are not dunk tanks !
They are BACTA TANKS! Get your facts right please.
Its also called a rejuvenation tank.
A bacta tank and a supply of bacta were expensive, the tank
alone typically costing 100,000 credits
from 32 BBY to 8 ABY, so such medical
equipment was usually found only in hospitals, on board capital ships,
and within major military bases. Movement of bacta tanks could
prove difficult because the tanks weighed roughly 500
kilograms.
Luke Skywalker would have almost surely died from his injuries
if not for Echo base's bacta tank. After the battle of Endor, the
New Republic initiated a bacta war to liberate the remaining bacta
and spread it across the galaxy.
