I think Russians should have done this freely for Armenians, since I doubt if they are able to pay anything.

MOSCOW, March 4 (RIA Novosti) – Russia has strengthened its airbase in Armenia with a batch of overhauled MiG-29 fighter jets, a military official said Tuesday.
Russia’s 3624th Air Base at the Erebuni airport in Yerevan previously hosted at least 16 MiG-29 Fulcrum fighter jets operating under the framework of air defense agreements concluded between the members of the Commonwealth of Independent States.
“A batch of fourth-generation MiG-29 multirole fighter jets has been put in service with the Russian airbase at Eerebuni after an extensive overhaul,” a spokesman for the Southern Military District, Col. Igor Gorbul, said without specifying the number of aircraft.
The Erebuni air base is part of Russia’s 102nd military base in Gyumri, near Armenia’s border with Turkey.

The Russian military said in January that in addition to fighter jets the Erebuni base
will soon host a helicopter squadron armed with at least 18 attack and military transport choppers.
