Will explosive USVs become the new torpedo boats?

Will most navies acquire small explosive USVs as modern equivalents of torpedo boats?

Many will develop designs and related mine-warfare craft, but peacetime fleets may defer buying expendable attack versions when conventional torpedoes already cover part of the role.

Ukraine's requirements arise from its particular constraints and do not map directly onto every established navy. Other fleets may keep designs ready, experiment with uncrewed mine warfare, and wait to build explosive attack craft at scale until a crisis. The answer distinguishes technical possibility from a durable peacetime acquisition program.
