Ok, thanks again for feedback. Now pennant number and extra radar fixed; somehow I thought that Aster would need that. I agree that NH 90 would be better choice for this, at least from maintenance point of view, but as you said it don't fit here.
Yet, considering that we should replace all minelayers and Rauma-class with this kind of ship (3-4?) the number of helicopters should be at least 5-7. Apparently that is in the edge of cost effective maintenance? Of course, if the Navy buyes my trimaran FAC, they need less of these
But to be serious, what might be unit prize of corvette this size? Could it be somewhere 200milj. €?
