Grigorovich responded to a requirement for a reconnaissance-bomber, for use in the Baltic Sea and Black Sea, issued by the Imperial Russian Navy central headquarters. The resulting large seaplane following the layout of the Sikorsky Ilya Muromets, with a large glazed cabin sitting atop a long slender fuselage. The fuselage and large wings were mounted on a large central float, which also housed a large gunners cockpit housing two gunners. The wings, mounted with flexible bungee joints allowing up to 180 mm (7.1 in) of movement, also carried wing-tip floats for stability on the water. Two 220 hp (160 kW) Renault 12E V-12 water-cooled engines were mounted in strut-supported nacelles between the upper and lower mainplanes. A third engine was added to the centre section of the upper mainplane, to address perceived centre-of-gravity problems and increase the power available; initially this was to have been a 150 hp (110 kW) Sunbeam Crusader, later replaced by a 140 hp (100 kW) Hispano-Suiza 8A before flight trials commenced.[1]
The sole MK-1 was readied for flight trials in mid-November 1916 but nosed over and sank during taxy trials before the first flight.[1]
