Russian flag-carrier Aeroflot has submitted a tentative time schedule for acquiring domestically-built aircraft to the Government.
In a letter to prime minister Vladimir Putin, dated last month, the airline's chief Valery Savelyev specifies its acquisition plans to 2020.
It follows a meeting with Putin earlier this year during which the prime minister lashed out at Aeroflot for its apparent reluctance to acquire domestically-built aircraft.
A spokesman for the company says Aeroflot is planning to purchase 40 Sukhoi Superjet 100s, 11 Antonov An-148s and 25 An-140s before 2016.
The aircraft are intended to modernise the fleets of Aeroflot and six associate carriers, of which it is taking over management control.
In addition, Savelyev says Aeroflot is prepared to take up to 50 medium-range United Aircraft MS-21 twin-jets in the period between 2016 and 2020.
He indicates this would bring the share of domestically-built equipment in the group's integrated fleet to almost half, up from the current 10%.
Aeroflot has firm orders for 30 Superjet 100s, while Rossiya - one of the carriers being integrated - is to receive two more An-148s.
Savelyev, in his letter to Putin, points out that sticking to "the tight schedule" of aircraft delivery will depend on domestic manufacturers and their capability to fulfil orders in time.
He reminds that, under the agreement with Sukhoi, Aeroflot was supposed to begin taking Superjets in 2008 but has received none yet.
