). Infrared seeker was developed by TsKB-589 GKOT (currently TsKB Geofizika), who also developed seeker for 9M31 missile of 9K31 Strela-1.

History

The K-8's development began in 1955, known as R-8 in service. Like most Soviet air-to-air missiles, it was made with a choice of semi-active radar homing
Semi-active radar homing
Semi-active radar homing, or SARH, is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal – provided by an external ...

 or infrared
Infrared homing
Infrared homing refers to a passive missile guidance system which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track and follow it. Missiles which use infrared seeking are often referred to as "heat-seekers", since infrared is just below the...

Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

It was upgraded to R-8M (better known as R-98) standard in 1961, giving the SARH weapon the capability for head-on intercepts. In 1963 it was further upgraded to the R-8M1, making it compatible with the RP-11 Oriol-D radar of the Sukhoi Su-15

Subsequent development led in 1965 to R-8M2, more commonly called R-98, with longer range and improved seekers, compatible with the upgraded RP-11 Oryol-M ("Eagle") radar. The final variant, introduced from 1973, was the R-98M1 (NATO 'Advanced Anab') with better countermeasures resistance and longer range, matched to the Taifun-M radar of the Su-15TM

The R-98M1 remained in service through the 1980s, being withdrawn with the last Su-15 'Flagon' interceptors.

A variant using the seeker heads of the K-13, giving better dogfight capability, was developed in 1960 as the K-88, but it did not enter service.

An inert training version was also developed, designated UR-8M.

The R-98 brought down Korean Air Lines Flight 007 on Sept. 1, 1983.
