Russian Tank development - did I get it right? I have some problems understanding the russian tank development...Thats how I think it goes: (1) First T-54, T-55 and T-62 as mediocre, but reliable and mass produced tanks. (2) After that, a policy of two tanks at the same time, a high quality one and a cheap mass produced one. The high quality tank is the T-64, the mass produced one the T-72 (3) The T-64 gets replaced by the T-80, the T-72 is still kept in service because he was introduced later. (4) The T-72 is developed further into the T-90, the new replacement for the T-80 is still vague, many different concepts (T-95, Black Eagle etc. etc.) (5) Because of monetary concerns, and a higher export demand, the two tank policy is dropped. Only the T-90 is kept in production, and is from now on russias MBT. (6) T-72, T-80 and T-90 are continiung their service until ~2025, when they all are supposed to be replaced by one new MBT. Is this about right...?
