Motor torpedo boats evolved into missile-armed fast attack craft

Did motor torpedo boats become obsolete?

They evolved through motor gun boats into modern fast attack craft, which usually carry missiles and may combine additional coastal-warfare roles.

The motor torpedo boat did not simply disappear. Wartime boats also served as motor gun boats, and the basic fast coastal combatant evolved into missile-armed fast attack craft. Finnish vessels and Sweden's Visby class provide modern points of comparison. Visby's composite construction supported a mine-countermeasure requirement, but combining that role with other combat tasks made the ships more expensive. A platform lineage can survive while its principal weapon and design priorities change.
