The Grigorovich MR-2 was a long-range reconnaissance flying boat designed by the Grigorovich Design Bureau for the Soviet Navy in the late 1920s.
Recognition (WEFT)
| W — Wings | Mid-mounted, straight |

| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.

- Biplane flying boat
- Larger upper wing than the MRL-1
- Single W-12 water-cooled engine
A twin-wing flying boat with a larger upper wing, 13.6 m long on a 15.6 m span.

History
It was similar to the MRL-1 but had a more powerful 450 hp Lorraine-Dietrich 12E engine and a larger upper wing, with an improved and less expensive hull construction. Flights began on 23 September 1926 and impressed its designers.
Variants
Only one aircraft of this type was built.
Where you'll see it
State acceptance trials were carried out by VVS pilot F. S. Rastegaev. A flight on 19 October ended in disaster when the MR-2 lost stability, and longitudinal oscillations of increasing amplitude put it into a steep dive and it crashed into the water upside down.
