The S-13 unguided aircraft rockets are classified as airto-ground rockets. The basic rocket is a concretepiercing rocket, type S-13, comprising an extended high-energy solid-propellant rocket motor and penetrating warhead.
The S-13 rocket boasts a number of modifications with
- S-13T with two-module HE fragmentation concretepiercing warhead;
- S-13-OF with HE fragmentation warhead;
- S-13D with fuel-air explosive warhead;
- S-13DF with enhanced power fuel-air explosive warhead.
The weapon system had been built to help tackle a major task facing front-line and army-level aviation, that of destroying hostile aircraft kept in a variety of concrete shelters, as well as destroy runways, command posts, communications nodes and other fortified facilities.

The S-13 is intended to destroy aircraft in reinforced concrete shelters, as well as war materiel and manpower in hardened shelters. The S-13T is intended to destroy aircraft in different types of shelters, including reinforced ones, demolish runways and defeat command, control and communications posts and other objects. The S-13T rocket is developed from the S-13 to enhance its lethality owing to employment of two separable autonomous warheads: the first warhead is a penetrating type (analog of the S-13 rocket warhead), while the second one is a HE fragmentation warhead. Design solutions, used to develop the S-13T rocket, enabled the designers to increase the quantity of explosives to be delivered behind a barrier and ensure the optimal spread of warhead blasting zones behind the barrier that made it possible to sharply increase the effectiveness of the S-13T rocket compared with the S-13, maintaining its penetration capability. The S-13T rocket development is based on the modular principle, providing for the exclusion of the second warhead (second module) (in this case the S-13T turns into the S-13) or its replacement with another purpose warhead.

S-13-OF, S-13D, S-13DF
These rockets are intended to engage lightly armored, easily vulnerable materiel and manpower. The S-13-OF is a rocket with a HE fragmentation warhead with pref o r m e d d i a m o n d - shaped splinters. T h e w a r h e a d i s equipped with a tail fuze. To delay the fuze operation time, the warhead is fitted with an elongated noze cap. The S-13D is a rocket whose warhead is filled with fuel-air singleaction explosive mixture and fitted with a point contact fuze. The S-13DF is a rocket with an enhanced power warhead filled with fuelair explosive mixture. Unguided aircraft rocke t s a r e c l a s s i f i e d according to use as main and auxiliary (special).
