A Mark 41 successor could continue the same design family

What is likely to replace the Mark 41 vertical launch system?

A further evolution of Mark 41 itself is the expectation, given the changes already made within that system family.

Continued evolution of Mark 41 is the expected route. The system has already undergone repeated changes while retaining its name. A perimeter-mounted alternative is mentioned, but its designation is unclear in the spoken recollection.
