Question

What disadvantages does the Virginia Payload Module create beyond procurement cost?

Short answer

The longer hull is harder to maneuver underwater, even if its proportions may improve speed.

Notes

Lengthening the submarine increases its length-to-beam ratio. That may improve speed while making the boat harder to maneuver underwater. Seabed topography still imposes handling constraints, so payload capacity comes with a change in how the boat can move.
