A strong impetus to ramping up the output of machines of the type was given by the governmental order for 22 Mi-26s for the Russian Defence Ministry, which was awarded in 2010. The first two aircraft under the contract were delivered in October 2011 and two more followed suit late in the same year. During 2012, as many as six Mi-26s were made under the governmental defence acquisition programme. Four more were fielded with a combat units last year. Another two have been manufactured and already tested this year. Russian Army Aviation units in the Russian Far East, Urals and Rostov and Pskov regions operate brand-new Mi-26s.

Early last year, a brand-new Mi-26T was delivered to a Russian commercial operator. The machine (RA-06255) was made in late 2012 and delivered to the Rostvertol-Avia airline that had operated three aircraft of the type. In addition to the domestic market, Rostvertol-built heavylifters have been exported of late. For instance, three Mi-26TC helicopters were shipped to China during 2007-10, and three Mi-26Ts entered service with the Venezuelan Army Aviation in 2007-08.

According to Rostvertol's 2013 annual report, the company's upgraded Mi-26T2 foreign-market promotion efforts came to fruition when the first export deal was clinched on 26 June 2013 for six machines for Algeria. The construction of the first two production-standard Mi-26T2s is in full swing in Rostov-on-Don, and the aircraft may be shipped to the customer before year-end.

The key difference setting the Mi-26T2 from the production-standard Mi-26 and Mi-26T/TC is its sophisticated digital avionics suite that has allowed slashing the flying crew from four to two (from five to three, if the external cargo sling is used) and simultaneously improved reliability, flight safety, helicopter's stability, controllability and hover precision, which is especially important when using the external sling.

The BREO-26 avionics suite of the upgraded Mi-26T2 is based on the NPK-90-2 flight navigation system comprising the digital display system, control panels, airborne computer, satellite navigation system and digital flight system. In addition, the Mi-26T2's avionics incorporates an up-to-date communications system and an airborne flight recorder system.

Just like its baseline model, the Mi-26T2 can haul outsize cargo and vehicle weighing a total of 20 t in the cargo hold or at the external sling. Its military version carries 82 troops and casevac variant airlifts 60 casualties. The machine can perform installation and construction work of varying degrees of complexity, fire-fighting missions, quick fuel delivery, self-contained refuelling of vehicles on the ground, etc.

A Mi-26T2 prototype (tail number 901) was made by Rostvertol and submitted for its flight trials early in 2011. To date, it has passed all of the key phases of the trials and Mi-26T2 entered full-rate production.
