The first S-500 55R6M Prometey (Prometheus) strategic air-defence system has entered service with a unit in the Moscow region, the TASS news agency reported on 13 October, citing a source close to the Russian Ministry of Defence (MoD).

The first regimental set is to be followed by a second in the first half of 2022, the source added. No official announcement has been made by the MoD, but Deputy Prime Minister Yuri Borisov told the RIA Novosti news agency in September that deliveries were under way to Russian forces. These initial S-500 units may be intended primarily for training purposes or limited service, as the Izvestia newspaper reported on 12 October that Rostec CEO Sergei Chemezov has said serial production and deliveries of the S-500 are scheduled for 2025.
