75kts with 90 max is very reasonable. It would be interesting to know anticipated ff in pph with those big turbines, and capacity. The max altitude is only 9000'. My last (been a while) airship had a ceiling of 10000'. We never got near to this, pressure altitude coming in to play (flat ballonets) Around 6000' I think, is the highest we managed, so again 5-6000 is probably realistic.
This bird has a great range, 3225 nm. It could be a useful tool to any oversize freight outfit. let's hope development costs don't kill it.
