Editing Synchronization gear (section)

=== Russia ===
No Russian synchronization gears went into production before the [[October Revolution|1917 Revolution]] – although experiments by Victor Dibovski in 1915 contributed to the later British Scarff-Dibovski gear (described above), and another naval officer, G.I. Lavrov, also designed a gear that was fitted to the unsuccessful [[Sikorsky S-16]]. French and British designs licence-built in Russia used the Alkan-Hamy or Birkigt gears.<ref name=Woodman17/>

Fighters of the Soviet era used synchronized guns right up to the time of the [[Korean War]], when the [[Lavochkin La-11]] and the [[Yakovlev Yak-9]] became the last synchronizer-equipped aircraft to see combat action.
