The bomber was fitted with a newly developed Roobin-1K (Ruby) search and target illumination radar which has a maximum range of approximately 200 kilometers.

The missile was prepared for launch by the navigator; the degree of automation provided by the Roobin-1K eliminated the need for a separate radar operator.

The rocket motor fires immediately after release in boost mode, accelerating the missile to its cruise speed.

Once the missile turns on an approach course to the target, the motor switches to cruise mode, shutting down one of its chambers.

A target drone version of the missile designated KRM-2 (MV-1) also entered service in 1966, with a different rocket motor, a range of 376 kilometers and a level flight endurance of 433 seconds.
