France actually built a dedicated "LCS" class - the Bougainville
Aviso Colonial class, around 1930.
These were designed for standalone overseas littoral patrol duty, and carried light destroyer armament (three 5.4" guns plus 37mm AA guns and MGs), and could carry and support up to a company of marines, or also carry and lay up to 50 mines. They also carried a single seaplane. In WW2, they were modified as primary ASW escorts with mine rails replaced by DC rails, a ASW mortar fitted, and of course a heavier AA outfit.
Interestingly, they were a similar small size as LCS (2600 tons FL, 340ft long), but machinery outfit focused more on extremely long range than speed.
Post-WW2, the survivors were listed as frigates under NATO "F" pennants, previously they were listed 1st Rate Avisos. One acted as an escort in the Korean War, including for the Inchon landings.
