Moskalyev SAM-7 Sigma
Moskalyev / Aviakor · Soviet Union · first flew 1935 · fighter
The Moskalyev SAM-7 Sigma was a Soviet experimental high-speed aircraft of the mid-1930s, designed by Alexander Moskalyev to explore the limits of aerodynamic efficiency achievable with the piston engines of the day. It demonstrated impressive speed for its time.

WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Soviet 1930s experimental high-speed monoplane
- Designed by Alexander Moskalyev as a speed research aircraft
- Very clean aerodynamic form for its era
A small, very clean single-seat low-wing monoplane with a tightly cowled engine and minimal protrusions; the smooth lines distinguish it from more workmanlike Soviet fighters of the period.
Specifications
- The Moskalyev SAM-7 Sigma has a length of 7 m (23 ft).
- It has a wingspan of 9.46 m (31 ft).
- Its maximum speed is 435 km/h (270 mph).
- Typical crew: 1.

History
First flown in 1935 at the Voronezh aircraft factory, the SAM-7 Sigma was part of Moskalyev's series of innovative designs exploring aerodynamic efficiency. The aircraft was not developed into a production type but contributed to Soviet understanding of high-speed aerodynamics in the pre-war period.
Variants
A single prototype was constructed; no production followed.
Where you'll see it
The SAM-7 did not enter VVS operational service.
