How Babbage's computing work could aid naval design

Would the Difference Engine be Turing-complete in the proposed accelerated development programme?

Turing completeness is doubted, but the anticipated calculation capacity would still help with naval design.

The Difference Engine is not expected to reach the Turing-complete level suggested in the question. It is nevertheless expected to provide enough computation to help substantially with ship-design calculations. Within the 1850 counterfactual, useful calculation capacity would have value even without a fully general computer.
