Grigorovich M.11

The small Grigorovich M.11 Flying Boat was designed as a small fighter, and it was first built in the summer of 1916. As a two-seater, it was found to be underpowered. The gunner was provided with a machine gun on a pivoting arm. The single-seater version had the gun fixed on the deck in front of the pilot and also fitted light armor to critical areas. One hundred M.11s were ordered but only seventy-five were delivered, and it was used on the Black Sea and the Baltic.

In winter a ski undercarriage was deployed, allowing landing on frozen lakes and level fields.
