Why Bismarck cost figures need caution

Given a quoted Bismarck-class cost of $490 million in 1940 US dollars, could Germany have built something much cheaper?

The quoted cost is itself disputed: incomplete records and omitted infrastructure spending could put the total higher. No cheaper alternative is priced.

A quoted cost of $490 million in 1940 US dollars for the Bismarck class is challenged as an estimate. The concern is that incomplete German records make the accounting difficult to check. Infrastructure limitations and the investment needed to overcome them may also sit outside the quoted construction figure. The cost could therefore have been higher, but no verified alternative total is supplied.
