On ships the Licornes were used differently to Spanish Obusier (otherwise similar) or British or French Shell guns/Canon-Obusier/Obusier, as they were usually supplied 'common bore' as replacements for a pair of guns with a weaker gun capable of firing a less safe shell.

The other nations used a *heavier* shell gun in the same situation (48Livre Obusier/36 Livre or 24 Livre guns within the main battery for Spanish, 8 Inch/32lb guns for British (1830s), or 22cm/30 Livre for French use (1830s)).
Shells were considered dangerous to the users, and were avoided until the 1820s even for guns designed to use them, until better shell handling/shell roms/enclosed percussion fuses, replacing exposed powder trains lit by firing the gun.
This made the Obusier de Vaisseau less useful than it *could* have been, and might have had some effect on Russian practice - the pieces were only supplied on mobilisation for war (which cannot have improved proficiency and safety, but their employment seems to have been very successful vs Ottoman fleets).
