The 9K35 Strela-10, which has the NATO designation SA-13 Gopher, is a self-propelled short range SAM system. It is based on the MT-LB tracked amphibious chassis. Four versions of the launch vehicle were created, which differ only in minor details and equipment associated with improved missiles.

Strela-10SV: This was the first version and was produced in limited quantity. It is capable of firing the 9M31 and 9M37 missiles.
Strela-10M and Strela-10M2 are near similar and the most common models. In addition to the 9M31 and 9M37 they fire the 9M37M and MD missiles.
Strela-10M3: This is an improved launch vehicle capable of firing the 9M333 missile.
Strela-10M4: Designation for earlier models updated to M3 standards.

9M37: The 9M37 is an enlarged and more capable version of the earlier 9M31 missile and is fitted with an improved infra-red seeker. The missile has a conventional layout with the seeker in the front, followed by the warhead and the rocket engine. It is transported and launched from a ribbed container.
9M37M: Improved 9M37 that features a further improved infra-red seeker.
9M37MD: A 9M37M missile fitted with a heavier and more capable warhead.
9M333: The 9M333 is the latest missile for the 9K35 system and is a further improvement of the 9M37MD. It features a dual mode seeker with photo contrast and passive infra-red guidance. The 9M333 has a much better resistance to flares and decoys and is able to lock on to smaller targets such as UAV's and cruise missiles.

Strijela-10 CROA1: Croation modification of the Strela-10 system. Due to a lack of MT-LB chassis the launcher was placed on an armored version of the TAM-150 6x6 truck chassis. Only about 6 of such conversions were carried out. The CROA1 may launch the 9M37 missile, the improved 9M37M, the further improved 9M333 and the older and smaller 9M31 from the 9K31 Strela-1 system.
