Larger hulls make machinery and computer redundancy easier

Dividing capabilities between several vessels increases dependence on their data links and continued availability. A larger hull offers room for additional generating machinery, reducing the effect of losing one plant. The illustrative comparison contrasts several diesel generators and multiple gas turbines with a smaller craft carrying fewer of each. Computers also need duplicate or triplicate systems already running and mirrored, so a failure does not interrupt control. The machinery counts illustrate the redundancy argument and are not a confirmed Type 83 installation.
