The first production examples of the Mi-28N completed factory flight and armament tests in late May 2006, and were received by the Russian Air Force on 5 June 2006. The Mi-28N was officially accepted three years later, in October 2009. It was assumed the Mi-28N would fully replace the older Mi-24 variant in the Russian Armed Forces by 2015. In September 2011, six Mi-28Ns of the Russian Air Force took part in the 2011 Union Shield joint Russian-Belarusian military exercise at the Ashuluk training ground in Astrakhan Oblast, Russia. To improve training of pilots for the Mi-28N, the Russian Defense Ministry announced to procure up to 60 Mi-28UB training-and-combat versions by 2020. Four to six Mi-28UBs would be purchased for every unit that operates the Mi-28N. An initial batch of 24 Mi-28UB training-and-combat helicopters was ordered in April 2016, and first two serial Mi-28UBs arrived at the Torzhok Air Base on 16 November 2017. In October 2016, a prototype of upgraded Mi-28NM helicopter performed its maiden flight. The Russian Defence Ministry has ordered first batch of Mi-28NM helicopters in December 2017, not disclosing the number of helicopters ordered. In March 2019, a Mi-28NM prototype was seen accompanied by a Mi-24/Mi-35M during a combat sortie over a rebel-held territory in the northern Hama. It was reported the helicopter was sent to Syria to underwent testing in difficult weather and climatic conditions. The Russian Air Force has received first two serial Mi-28NMs on 23 June 2019.
