OVERVIEW:  The SA-20a GARGOYLE A (48N6) aka SA-10d is a single stage, solid fuel, long-range, Track-Via-Missile (TVM),  surface to air missile with anti-stealth  capability.  It has a 143 kg warhead.

DETAILS: The SA-10/SA-20 series was developed as an area defense/strategic SAM system for both land and naval use. Its uses a combination of  inertial navigation system (INS), command link and TVM for guidance. The TVM guidance requires target illumination from a ground station and reception of the reflected signal by the missile, which relays it back to the ground station via a datalink.  The ground station then computes an interception course and uses the datalink to send guidance commands back to the missile.  The missile uses a thrust vectoring system for enhanced mauverability.

NOTES:  IOC 1990 (approx). The 48N6 is associated with the S-300V (army)/S-300P (A/D) and S-300F (naval) systems. In naval use, it is known as the SA-N-6 "Grumble."  The SA-20a is a "deep modernization" of the SA-10 system with design changes to most SA-10 components. To ensure missile reliability, the missile uses the TPK combined launch and transport container. This container was never opened until missile launch. The vertical launch technique adopted used a catapult accelerator within the container to pop the missile to an altitude 20 m above the launcher, where the main motor ignited.
