 In 1945, a B-29 bomber cost $ 782,000. It cost $ 32,000 to upgrade an aircraft to Silverplate configuration, so the total cost of a Silverplate bomber was $ 814,000. The total cost of the 65 wartime Silverplate B-29s was therefore $ 53 million. Adding $ 7 million for logistics, this put the estimated cost of the Silverplate project at around $ 60 million.
