Russian Empire
The Russian Empire, also known as Imperial Russia or simply Russia, was an empire that existed across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917.
Russian Air Force
The Russian Air Force (, literally "military air forces of Russia") is a branch of the Russian Aerospace Forces, the latter being formed on 1 August 2015 with the merger of the Russian Air Force and the Russian Aerospace Defence Forces. The modern Russian Air Force was originally established on 7 May 1992 following Boris Yeltsin's creation of the Ministry of Defence; however, the Russian Federation's air force can trace its lineage and traditions back to the Imperial Russian Air Service (1912–1917) and the Soviet Air Forces (1918–1991).
