Mikoyan-Gurevich (MiG) · Soviet Union · first flew 1958 · fighter

The Mikoyan-Gurevich I-75 was a Soviet experimental high-speed interceptor prototype of the late 1950s, exploring delta-wing aerodynamics at speeds above Mach 2. It informed the development of Soviet interceptors of the 1960s.

Spot it by:

Soviet late-1950s delta-wing interceptor prototype
Armed with Bisnovat R-4 air-to-air missiles
Precursor technology to the MiG-21 family

A slender delta-wing monoplane with a pointed nose intake and a single large jet exhaust; the long, thin fuselage and short-span delta wing are characteristic of Soviet Mach 2 interceptor research aircraft of the period.

History

Flown in 1958, the I-75 was a testbed for missile armament and high-speed aerodynamics. The aircraft achieved speeds of approximately Mach 2.2, validating the delta configuration for Soviet interceptor requirements. It contributed data that influenced subsequent MiG and Sukhoi interceptor designs.

Variants

A small number of prototype and development aircraft were built; no production series followed.

Where you'll see it

The I-75 did not enter operational Soviet service, being a pure research and development platform.
