Pendulum swings.
Post-USSR, Russian military aircraft production fell off a cliff, especially deliveries to the country's own armed forces - exports mainly to India and China were practically the only business sustaining the industry. The charts don't really include this period which lasted until 2010 approximately - else the whole notion that there was a decline at all would be ludicrous. What followed was a catch-up phase where 20 years worth of procurement and modernization backlog were cleared on top of a normal pace of re-equipment, adding more than 350 4.5 generation fighters in 10 years. That's twice the rate of delivery of Eurofighter partners UK, Germany and Spain (comprising 3 of the top 5 EU economies) *combined*, which accepted approximately the same number of aircraft, but spread out over 20 years! Is the tempo declining from this abnormally high level? Sure, but that frenzied pace was never going to last indefinitely, nor was it planned to. Recent economic problems may make the slow-down more marked than it otherwise would have been, but production is not going back to near-zero either.
