Lissa's long shadow over Italian warship design

How long did fear of close-range battles after Lissa affect the Regia Marina?

It remained part of Italian design ethos into the Second World War.

The Battle of Lissa became a durable institutional memory rather than a short-lived tactical fashion. The expectation that combat might collapse into close-range action continued to influence Italian layouts and fittings. That design ethos remained visible as late as the Second World War. A dramatic fleet experience can remain embedded in design culture long after technology and likely operating conditions have changed.
