What is the Buk-M3 Viking? Russia’s Medium-Range Air Defense System, Explained
The Buk-M3 Viking – NATO reporting name SA-27 Greyhound – is Russia’s standard medium-range tactical surface-to-air missile system, designed by the Almaz-Antey Concern’s NIIP Tikhomirov design bureau and produced by the Ulyanovsk Mechanical Plant. The most modern variant of the long-running Buk family (originally the Soviet 9K37 from 1979), the Buk-M3 entered Russian service in 2016 and replaces the older Buk-M1 and Buk-M2 systems that had been the standard Soviet/Russian battlefield mid-tier SAM for forty years. The Buk-M3 carries the 9M317M missile with a 70 km engagement range – the largest range increase in the family’s history.

The MH17 controversy
The Buk family entered global public attention on 17 July 2014 when a Russian-supplied Buk-M1 system operated by separatist forces in eastern Ukraine downed Malaysia Airlines Flight 17 over the Donetsk Oblast, killing 298 civilians. The Dutch Safety Board’s 2016 investigation conclusively identified a 9M38 missile fired from a Buk-M1 launcher as the cause. In November 2022, a Dutch court convicted two Russians and one Ukrainian in absentia for their role in the shootdown. The MH17 incident remains the deadliest single attribution of a Buk system in history and continues to influence Western perception of the platform.
The Buk-M3 modernization
The Buk-M3 represents the most thorough redesign of the family since 1979. Key changes from Buk-M2:
- Canister-launched 9M317M missile – sealed missile canisters replace the previous open-launch rail design, dramatically improving missile reliability and reducing required maintenance.
- 6 missiles per launcher (up from 4 on Buk-M2) – 50 percent more ready rounds per battery.
- Range extended to 70 km – 40 percent increase.
- New TELAR design with improved off-road mobility and digital fire control.
- Compatibility with the new Polyana-D4M1 command-and-control system, allowing integration with S-400 and Pantsir-S1 batteries for layered defense.
Combat record
- 2008 – Russo-Georgian war. Russian Buk-M1 batteries downed multiple Georgian Su-25 aircraft.
- 2014-2022 – Ukraine pre-war. Separatist-operated Buk systems (including MH17) engaged Ukrainian aircraft.
- 2022-present – Ukraine war. Russian Buk-M2 and Buk-M3 deployed extensively. Confirmed Russian-claimed kills include several Ukrainian Su-25s and MiG-29s. Verified Russian Buk losses to Ukrainian counter-strikes (including Storm Shadow and HIMARS) number in the dozens.
- 2024 – Syria. Russian Buk-M3 deployed alongside S-400 at Khmeimim airbase.

Why the Buk-M3 matters
The Buk-M3 has been the standard Russian battlefield mid-tier SAM through one of the most intense modern air-defense engagements in history. Its tracked mobility, vertical launch, and 70 km range make it the only Russian mid-tier system that can move with armored formations while engaging cruise missiles and high-altitude aircraft. Despite documented losses to Ukrainian precision strikes, the system remains in production at Ulyanovsk and continues to be the workhorse Russian mid-tier SAM. The Buk-M4 next-generation variant is publicly discussed but has not yet entered series production.
