The S-13 unguided aircraft rockets employed from aircraft and helicopters.
The S-13 unguided aircraft rockets are classified as air-to-ground rockets.
A number of rocket versions with different warheads are available:
- S-13-T – with two-module concrete-piercing HE warhead;
- S-13-OF – with HE fragmentation warhead;
- S-13DF – with enhanced FAE warhead.
The rockets are intended to engage different types of ground targets (from manpower to armored materiel and hardened shelters).
The rocket with a HE fragmentation warhead fitted with prefabricated diamond-shaped fragments. The warhead is equipped with a tail fuze. To compensate the warhead digging into the earth during the delay time of fuze action, a simple and reliable solution was implemented: an elongated noze cap.
Operating temperature range for all rocket versions is ±60° C.
