The Grigorovich MUR-1 (Morskoi Uchebnyi Rhône — Naval Training Rhône) was a Soviet two-seat naval pilot training flying boat derived from the wartime Grigorovich M-5, first flown in 1926. It used a Le Rhône rotary engine, explaining the 'Rhône' designation.
Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | 8 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Flying boat hull — no wheeled undercarriage
- Equal-span biplane derived from the M-5 trainer
- Two open tandem cockpits above the hull
A biplane flying boat with open tandem cockpits above the hull and a Le Rhône rotary engine; the absence of any wheeled undercarriage and the clean M-5-derived hull are the principal recognition features.
Specifications

History
Built to replace ageing M-5 trainers in Soviet naval aviation schools, the MUR-1 was reviewed by TsAGI, which identified shortcomings compared with the original M-5. A modified MUR-2 was subsequently developed to address these deficiencies. The type served briefly in Soviet naval training units.
Variants
Followed by the MUR-2, which incorporated TsAGI-recommended improvements.
Where you'll see it
Used in small numbers by Soviet naval aviation training units in the mid-1920s.
