How many is T-80BW? In fact modern tanks number is around 1000...
There were several thousands of different T-80, now I haven't a list of current formations (how many of them are active and in reserve), but there are many units with BV, recently also in Kuril islands.
All currently active units, T-90A, T-90, modernised T-72B, T-72B and T-80 variants make up about 2000, that is not counting tanks in storage.
Hold a second -as I know T-72BA (Ob.184A1) is in 220 numbers. And whit Sosna-U main sight less then 60 tanks. Those tanks where produced in last decade.
Can you give source about 300 new T-72BA2 in next 3 years?
"T-72BA" was purchased before 2011 and there were different variants of modernisation, I do not know exact number, maybe about 100.
Contract for T-72B1 (Sosna-U, 2A46-M5...), which is not named T-72BA, was signed on march 2011 but details were not officially disclosed. According to
reports it is about 100 for 3 years, indeed
http://www.rosoboronpostavka.ru/documents/pg_mo_2013_1.pdf second year contract (2012-2013) for 2013 is for 101 tanks, now first year tanks should be already delivered in 2011-2012, about 100.
"Imposiblu"
Impossible -take look about UVZ cheper and simpler T-90A (Ob.188A/A1) production. In best years it was 180 tanks per yer. Even If Armata will be ended "on time" (2015) -what is not so sure when we take a look in other russian military program... - then starting production need time. In fact the most optymistic possibility is ~500 new tanks in 2020. Propably mucht less...
IMHO Amrmata wil be ended whit 1-2 years later then it planed now.
Though I am skeptical, 460 tanks per year is possible. T-90A orders were under the capacity of the plant and there were many more including export and modernisations. Also UVZ since 2015 will operate new production facility currently under construction and will focus on new production, it will no longer be dedicated to T-72B upgrade which should shift to Omsk.
Because current T-72 upgrade contracts are not very rentable and are being ordered only to save capacity.
Also Armata is result of 2 decades of developement, ob 195 and most is already available, they are to show prototype on 2013, pass trials on 2014 and ready for production.
