Missile S-300V (SA-12 Gladiator)

The S-300V is a Soviet-designed mobile surface-to-air and anti-ballistic missile system, assigned the NATO reporting names SA-12 Gladiator/Giant and, for later variants, SA-23 Gladiator/Giant. The original S-300V entered service in 1983. Subsequent development produced the S-300VM (Antey-2500), the S-300VMD, and the S-300V4, the latter in service since 2014. The export designation of the S-300V4 is Antey-4000. Modernisation of Russian S-300V units to the S-300V4 standard was scheduled for completion in 2012.

The system engages short- and medium-range ballistic missiles, aeroballistic and cruise missiles, fixed-wing aircraft, loitering electronic countermeasures platforms, and precision-guided munitions. A battery is built around a command post, circular and sector scan radars using passive electronically scanned arrays, and a Multichannel Missile Guidance Station providing 24 illumination channels for simultaneous engagement of 24 targets. Fire units comprise the 9A82M and 9A83M launchers, each carrying its own illumination and targeting radar, supported by 9A84M and 9A85M loader-launchers. All elements are mounted on tracked cross-country chassis with self-contained power supply, navigation, surveying and positioning equipment, permitting autonomous operation.

Two missile types are employed: the 9M82M against tactical, theatre and medium-range ballistic missiles as well as aerodynamic targets, and the smaller 9M83M. Both are launched vertically from sealed transport-launch canisters and require no maintenance for at least ten years in storage. Guidance is inertial with radio command mid-course update, transitioning to semi-active radar homing in the terminal phase. The warhead uses focused detonation, and the system is credited with the ability to defeat individual ballistic missile warheads. Battle management is automated through high-speed digital computers, and the radars incorporate ECM-resistant data processing. One or two additional battalions can be added to a fire complex.

Russia is the principal operator, with S-300V4 units fielded across all four military districts, including brigades and regiments at Korenovsk, Gyumri, Naro-Fominsk, Znamensk, Birobidzhan, Yuzhno-Sakhalinsk and Mirny. More than three S-300V4 divisions had been ordered by 2015. In early October 2016 a Russian S-300V4 battery was deployed to the naval base at Tartus, Syria. In early December 2020 the system entered combat duty on the Kuril Islands.

Egypt ordered the Antey-2500 in 2014 under a Russian-Egyptian arms package; the $1 billion contract covered four batteries, a command post and associated elements. Deliveries began in 2015, with Egyptian crews trained in Russia, and all batteries had arrived by the end of 2017. Venezuela operates two S-300VM systems in a single air defence battalion at Base Aérea Militar Capitán Manuel Ríos. Algeria was negotiating for several battalions in November 2015. Turkish talks on a co-production arrangement ended with the shootdown of a Russian Su-24, and an offer to Saudi Arabia did not result in a sale.

Combat losses have been recorded in the Russo-Ukrainian War. On 18 August 2023 a Ukrainian drone filmed HIMARS rockets destroying S-300V4 missiles. On 25 February 2025 Ukrainian forces destroyed an S-300VM system in Zaporizhzhia Oblast with a bomber drone, which subsequently landed to film the burning launcher.
