Airplanes are built as part of March and December 2012 two contracts for the supply of each of 30 Su-30cm to Russian Air Forces (VKS) of Russia. Earlier in the period 2012-2016 for these contracts, Irkut has delivered to the Air Force (VCS) 48 Su-30cm.
In addition, during the 2015 Irkut passed four Su-30cm for Kazakhstan (serial numbers 1118, 1119, 1120, 1201) and five Su-30cm for the Russian Navy Naval Aviation (serial numbers from 1202 to 1206). By the end of 2015 at the Irkut plant have been transferred for flight testing five Russian Su-30cm aircraft (serial numbers 1301 - 1303, 1305 and 1307) for the Air force, but none of them has not yet been delivered to the customer.
So we have 50 Su-30SM delivered in total to the air force, out of 60 ordered. And there are also 5 more in flight tests to be delivered next days.
