The S-300PMU2/SA-10E Favorit system, later redesignated SA-20 Gargoyle, is the last of the Almaz S-300P variants to carry the S-300 designation. Developed between 1995 and 1997, it was intended to compete directly against the Antey S-300V and Patriot PAC-2/3 systems as an Anti-Ballistic Missile system.

The Favorit incorporates incrementally upgraded 30N6E2 Tomb Stone, NIIIP 64N6E2 Big Bird radars and a 54K6E2 command post, and the LEMZ 96L6E Cheese Board as its early warning and primary acquisition system, replacing the 36D6/ST-68UM Tin Shield and LEMZ 76N6E Clam Shell. While the system retains compatibility with earlier 48N6 missiles, a new extended 108 nautical mile range 46N6E2 missile was added.

The Favorit's new command post has the capability to control S-300PMU / SA-10, S-300PMU1 / SA-20 batteries, and also S-200VE / SA-5 Gammon batteries, relaying coordinates and commands to the 5N62VE Square Pair guidance and illumination radar.

While the Favorit superficially appears like the SA-10C/D, it has a wide range of incremental improvements internally, and a range of optimisations to improve performance in the Anti-Ballistic Missile role. Almaz, the system integrators, and Fakel, the missile designers, claim to have repeatedly caused Scud target vehicle warheads to detonate during test intercepts at the Kapustin Yar range in 1995.

The S-300PMU2 is the most advanced variant of the S-300P series to be exported in larger quantities, with the PLA being the principal client at this time.
