Not really Van, things were still pretty bad in 2013, even with a number of years of stimulus. Looking back with the clarity of hindsight it was probably 2014/15 that saw a marked improvement in the support, maintenance and availability to the more modern parts of the Russian Air Force. 2016 was arguably more impressive when the logistics system was given a serious pull-through. It is now possible to see a complete end-to-end (from manufacturer to frontline) deployable system for the Russian AF. Given the stretch on operational forces this new-found capability has not been reflected in export support.
The problem with rose-tinted glasses and pride is that it can mask what has been a massive and genuine improvement from what was a terrible position. The shift in genuine capability from 2012 to 2017 has been remarkable.
