Grigorovich M-16

The wing plan, similar in construction to that of the M-9 model , was characterized by presenting a large area, necessary to improve the suspension in a heavy aircraft with little engine power. The wing had an uneven span and three sections with supports and bracing using tension cables. Two flat-bottomed floats with a large support surface, necessary to operate on snow, were attached to the soffit of the lower plane. Each float weighed about 77 kg, to which had to be added a third very wide unit located under the tail region and weighing 8 kg. The tail unit featured a single drift and rudder assembly; Although with a general configuration similar to that of the M-15 hydrofoil, the rudder of the new aircraft extended behind the horizontal planes, and the stabilizers were supported by four spars coming from the wings. The central gondola, Farman type , accommodated the crew members located in tandem, the instrumentation, the machine gun and the fuel. Aft of the nacelle was a liquid-cooled 150-hp Salmson radial engine that powered a two-bladed propeller, and the radiators were located on the sides of the nacelle.

The defensive armament consisted of a Lewis , Maxim or Vickers machine gun located forward on a mobile mount and operated by the observer. The M-16 could carry up to 100 kg of small bombs.
