Soviet D-3 MTBs
The D-3 class was built in wood, and carrying torpedoes openly on deck could attain speeds of 32 knots(59 km/h, 37 mph). Later boats in the series had improved engines increasing operating speeds to 48 knots (89 km/h, 55 mph)!
Although not many D-3s served in the Black Sea they were quite active, sinking German Barges and an Italian midget submarine. A most notable action was the sinking of the Elbing-class large torpedo boat T-31 in the Battle of Nerva Island.
