- Ukraine has used sea drones to attack Russia's Black Sea fleet.
- It's now able to fit them with missiles enabling them to fire at ships, it says.
- Ukraine has had to improvise to offset Russia's naval superiority.
Ukraine claims it has fitted the floating drones it is using to devastate Russia's Black Sea fleet with missile launchers, making them even more deadly.
Ukraine's intelligence service, the SBU, in early January released grainy video footage which it claimed showed its "Sea Baby" drones firing missiles at Russian vessels.
