JP, quite. I was making the point that Trident and Vanguard were also ordered in small numbers so again jig costs were the issue.
I was going to comment on the delivery rate of the Vulcan - 1/month - then saw the Airbus was at 38/month.
I wonder what the economics of producing one V-bomber at 20/month for 5 years compared with one per month over how ever long? I think across the 3 types it was less than about 1/month over the 10 years over 3 manufacturers.
