The last five of the initial eleven were laid down between 1818 and 1823. The Great Flood of 1824 damaged three, but the Navy salvaged them, and two (Provoryni (1820) and Konstantin (1824)), fought at the battle of Navarino. By 1831 all of the first 11 had been captured, wrecked, or broken up, with the exception of Konstantin. She was hulked in 1837 and finally broken up in 1848.
